A parabola can be drawn given a focus of (0,7) and a directrix of y=−7. Write the equation of the parabola in any form.
Answer:
y = 1/28(x²)
Step-by-step explanation:
Not totally sure about this, but here's what I think is the answer:
focus (0,7)
directrix y = -7
Always a good idea to plot the point (0,7) and the line y = -7 so you can visualize what the parabola looks like.
From the graph, you can see that p = 7 (halfway between the focus and the directrix).
The vertex of this parabola is (0,0), which are your (h, k) values. You can see that from the graph. The parabola opens UP.
4p(y-k) = (x-h)² → 4p(y-0) = (x-0)²
4py = x²
y = x²/4p = x²/4(7) = x²/28
y = 1/28(x²)

Answer:
tanQ = 1
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ OPQ is an exterior angle of the triangle , then
∠ R + ∠ Q = 135°
90° + ∠ Q = 135° ( subtract 90° from both sides )
∠ Q = 45°
Then
tanQ = tan45° = 1

the current of a river is 2 miles per hour. a boat travels to a point 24 miles up stream and back in 5 hours . what is the speed of the boat in still water
Let's denote the speed of the boat in still water as "b", and let's denote the distance between the two points as "d" (in this case, d = 24 miles).
When the boat is traveling upstream against the current, its effective speed is b - 2 mph (since the current is working against the boat). When the boat is traveling downstream with the current, its effective speed is b + 2 mph (since the current is helping the boat).
We know that the boat travels a total distance of 24 miles upstream and then 24 miles downstream, for a total distance of 48 miles. We also know that the total time it takes for the boat to make this round trip is 5 hours. So we can set up the following equation:
24/(b-2) + 24/(b+2) = 5
Multiplying both sides by (b-2)(b+2), we get:
24(b+2) + 24(b-2) = 5(b-2)(b+2)
Simplifying and rearranging, we get:
10b^2 - 96b - 208 = 0
We can solve this quadratic equation using the quadratic formula:
b = (-(-96) ± sqrt((-96)^2 - 4(10)(-208))) / (2(10))
b = (96 ± sqrt(96^2 + 8320)) / 20
b = (96 ± sqrt(9024)) / 20
b = (96 ± 96) / 20
So the possible values of b are b = 9.6 or b = -0.8. We can discard the negative value since it doesn't make sense as a speed, so we have:
b = 9.6 mph
Therefore, the speed of the boat in still water is 9.6 miles per hour
Has the marrying age of a man changed over the years? The United States Bureau of the Census takes a formal count of everyone in the U.S. every 10 years and has provided the following data that gives the median age of an American man at the time of his first marriage.
What does a rate of change of zero mean in this situation?
a.
The median age of a man at the time of his first marriage is, on the average, constant.
b.
The median age of a man at the time of his first marriage is, on the average, decreasing.
c.
The median age of a man at the time of his first marriage is, on the average, increasing.
d.
The rate of change cannot be zero in this situation.
ITs not D so dont say it if you dont know the answer dont reply i put up this post for those who need to get the answer because all other post are wrong.
For the given data the general trend is neither continuously rising nor falling. thus, the correct answer is option a: The median age of a man at the time of his first marriage is, on the average, constant.
How to calculate rate of change of mean?We can compute the rates of change by deducting the current year's median age from the prior year's median age. A result of zero denotes no change, a result of zero denotes no decline, and a result of one denotes an increase.
[tex]\text{Rate of Change} = Median\; Age (current \;year) - Median \;Age (previous \;year)[/tex]
[tex]1910-1920: 24.6 - 25.1 = -0.5\\1920-1930: 24.3 - 24.6 = -0.3\\1930-1940: 24.3 - 24.3 = 0\\1940-1950: 22.8 - 24.3 = -1.5\\1950-1960: 22.8 - 22.8 = 0\\1960-1970: 23.2 - 22.8 = 0.4\\1970-1980: 24.7 - 23.2 = 1.5\\1980-1990: 26.1 - 24.7 = 1.4\\1990-2000: 26.8 - 26.1 = 0.7\\[/tex]
The rates of change, as we can see, alternate between positive and negative values, but the general trend is neither continuously rising nor falling. Several times, the rate of change is zero, showing that, generally speaking, the median age of a man at the time of his first marriage is holding steady through time.

Histogram from the other post like I said it would be great if someone could look this over for me thanks!
This is an image of a histogram representing the number of hours a group of students spent studying for a test. The horizontal axis shows the number of hours studied, and the vertical axis shows the frequency or number of students who studied that number of hours.
What is histogram?A histogram is a graphical representation of data that displays the frequency distribution of a set of continuous or discrete data. It consists of a series of adjacent rectangular bars, where the area of each bar represents the frequency of occurrences of a particular range of values.
Based on the histogram, it appears that the majority of students studied for 5-7 hours, with a frequency of 14 students. Additionally, it appears that 8 students studied for 2-4 hours, and 10 students studied for 8-10 hours. Finally, it appears that only 1 student studied for more than 10 hours.
Histograms are a useful way to display and analyze data because they allow us to quickly see the distribution and frequency of the data. In this case, we can see that the data is roughly symmetric around the 5-7 hour range, with fewer students studying for fewer or more hours.

A conic has vertices at (0,8) and (0,-8) and foci at F(0, √48) and F(0,-√48). (a) Write the standard form of the equation of this conic.
The standard form of the equation of the conic is x² + y² - 16x - 16y - 192 = 0.
What is conic?It is a type of curve with a curved line in the middle and two straight lines on the sides. Conic sections include circles, ellipses, parabolas, and hyperbolas.
The standard form of the equation of a conic is
Ax² + Bxy + Cy² + Dx + Ey + F = 0, where A, B, C, D, E, and F are constants.
In this case, the equation of the conic is x² + y² - 16x - 16y - 192 = 0.
To derive this equation, we'll use the distance formula to calculate the distance between the vertices and the foci. The distance between the vertices and the foci is given by
d = √((x_1 - x_2)² + (y_1 - y_2)²)
where (x_1, y_1) is the coordinates of the first vertex and (x_2, y_2) is the coordinates of the first foci.
For the first vertex, (x_1, y_1) = (0, 8). For the first foci, (x_2, y_2) = (0, √48). Thus, the distance between the two points is
d = √((0 - 0)² + (8 - √48)² )
= √(0 + (-8 - √48)² )
= √(-16 - 2√48 + 48)
= √(32 -2√48)
= 2√(16 - √48)
= 2√(16 - 6.9)
= 2√(9)
= 2(3)
= 6
So, the distance between the vertices and the foci is 6.
The equation of the conic can then be written as x² + y² - 16x - 16y - (-8)² = 0, which simplifies to x² + y² - 16x - 16y - 192 = 0.
Thus, the standard form of the equation of the conic is x² + y² - 16x - 16y - 192 = 0.

The minimum value of Jeri Dammers' total deductions is $200.68.
What is the deductions?Based on the given information, we can calculate the total deductions for Jeri Dammers as follows:
Social Security: Jeri pays 6% of the first S$90,000 of her gross pay towards Social Security. As her gross pay is only $735.00, her Social Security deduction will be:
Social Security = 6% of $735.00 = $44.10Medicare: Jeri pays 1.45% of all her income towards Medicare. As her gross pay is $735.00, her Medicare deduction will be:
Medicare = 1.45% of $735.00 = $10.65Federal Income Tax: To calculate the federal income tax, we need to refer to the tax tables provided by the IRS. As the gross pay is only $735.00, Jeri's federal income tax deduction will be very minimal or possibly none.
State Tax: Jeri pays 2% of her gross pay towards state tax. As her gross pay is $735.00, her state tax deduction will be:
State = 2% of $735.00 = $14.70Local Tax: Jeri pays 1.5% of her gross pay towards local tax. As her gross pay is $735.00, her local tax deduction will be:
Local = 1.5% of $735.00 = $11.03Medical: Jeri has a deduction of $32.00 towards medical expenses.
Union Dues and Others: No information is given about Jeri's union dues or other deductions.
Therefore, the total deductions for Jeri Dammers will be:
Total Deductions = Social Security + Medicare + Federal Income Tax + State Tax + Local Tax + Medical + Union Dues + OthersTotal Deductions = $44.10 + $10.65 + $0 + $14.70 + $11.03 + $32.00 + Union Dues + OthersTotal Deductions = $112.48 + Union Dues + OthersWe cannot calculate the exact value of Total Deductions without information about Union Dues and Others.

Identify the domain and range of the function. y=√x-4
A. Domain: x≥−4, Range: y≥0
B. Domain: x≥4, Range: y≥0
C. Domain: x≤4, Range: y≤0
D. Domain: x≥0, Range: y≥4
The domain of the function y=√x-4 is restricted by the square root of a non-negative number, which means that x-4 must be greater than or equal to zero. Thus, we have:
x-4 ≥ 0
x ≥ 4
Therefore, the domain of the function is x≥4.
The range of the function is determined by the output values of the function. Since the square root of any non-negative number is always non-negative, the output values of the function y=√x-4 will always be non-negative. Thus, the range of the function is y≥0.
Therefore, the correct answer is A. Domain: x≥−4, Range: y≥0.
You take out a loan in the amount of your tuition and fees cost $70,000. The loan has a monthly interest rate of 0.25% and a monthly payment of $250. How long will it take you to pay off the loan? Use the formula N= (-log(1-i*A/P))/(log(1+i)) to determine the number of months it will take you to pay off the loan. Let N represent the number of monthly payments that will need to be made, i represent the interest rate in decimal form, A represent the amount owed (total amount of the loan), and P represent the amount of your monthly payment. Be sure to show your work for all calculations made.
Therefore, it will take 173 months to pay off the loan, or approximately 14 years and 5 months.
What is percentage?A percentage is a way of expressing a number as a fraction of 100. The symbol for a percentage is "%". For example, 50% is the same as 50/100 or 0.5 as a decimal. Percentages are often used to express a portion or share of a whole. For instance, if you scored 90% on a test, it means you got 90 out of 100 possible points. In finance, percentages are commonly used to express interest rates, returns on investments, or changes in stock prices.
First, we need to convert the monthly interest rate from a percentage to a decimal by dividing by 100.
0.25% / 100 = 0.0025
Now we can plug in the values into the formula:
N= (-log (1-0.0025*70000/250))/ (log (1+0.0025))
Simplifying the equation in the parentheses:
N= (-log (1-175))/ (log (1.0025))
N= (-log (0.9964))/ (0.002499)
N= 172.9

Différenciation implicit function containing product and quotient. d/dx (2y/5x)
Answer:
To differentiate the given expression, we will need to use both the product rule and the quotient rule.
Let's first rewrite the expression using the reciprocal identity for x:
2y/5x = 2y * (5x)^(-1)
Now we can use the product rule and the quotient rule to find the derivative with respect to x:
d/dx [2y * (5x)^(-1)] = 2y * d/dx[(5x)^(-1)] + (5x)^(-1) * d/dx[2y]
Using the chain rule, we can find the derivative of (5x)^(-1) with respect to x:
d/dx[(5x)^(-1)] = -1/(5x)^2 * 5 * (dx/dx)
d/dx[(5x)^(-1)] = -1/(5x)^2
Using the chain rule again, we can find the derivative of 2y with respect to x:
d/dx[2y] = 2 * (dy/dx)
Substituting these expressions back into the original equation, we get:
d/dx [2y/5x] = 2y * (-1/(5x)^2) + (5x)^(-1) * 2 * (dy/dx)
Simplifying this expression, we get:
d/dx [2y/5x] = -2y/(5x)^2 + 2/(5x) * (dy/dx)
Therefore, the derivative of 2y/5x with respect to x is -2y/(5x)^2 + 2/(5x) * (dy/dx).
Is each number rounded correctly to the nearest hundred thousand?
yes is answer for all option .we can check it by rules of rounding off numbers .
what is rounding ?
Rounding is the process of approximating a number to a nearby value that is easier to work with or more appropriate for a given context. When rounding, we take a number with many decimal places or significant figures and adjust it to a simpler or more convenient value with fewer decimal places or significant figures.
In the given question,
Yes, each number is rounded correctly to the nearest hundred thousand based on the rules of rounding.
To round to the nearest hundred thousand, we look at the digit in the hundred thousand place and the digit to its right (i.e., in the ten thousand place).
If the digit in the ten thousand place is 5 or greater, we round up the digit in the hundred thousand place by adding 1.
If the digit in the ten thousand place is less than 5, we leave the digit in the hundred thousand place as it is.
Using these rules, we can see that:
350000 rounded to the nearest hundred thousand is 400000 because the digit in the ten thousand place is 5, so we round up the digit in the hundred thousand place.
555555 rounded to the nearest hundred thousand is 560000 because the digit in the ten thousand place is 5, so we round up the digit in the hundred thousand place.
137998 rounded to the nearest hundred thousand is 200000 because the digit in the ten thousand place is 7, so we round up the digit in the hundred thousand place.

Describe at least two differences between constructing parallel lines and constructing perpendicular lines.
By using the compass to measure a distance from the original line, and then transferring that distance to another point on the line, a parallel line can be drawn.
What is the parallel lines?
Parallel lines are two lines in a plane that never intersect.
1. Orientation of Lines:
Parallel lines are lines that never intersect and remain equidistant from each other at all points.
When constructing parallel lines, the lines are drawn in the same direction and maintain the same distance between them throughout their entire length. They do not meet or cross each other.
On the other hand, perpendicular lines are lines that intersect at a right angle (90 degrees). When constructing perpendicular lines, the lines are drawn so that they intersect at a right angle, forming four right angles at the point of intersection.
2. Tools/Methods Used:
Constructing parallel lines and constructing perpendicular lines may require different tools or methods.
To construct parallel lines, one common method is to use a straightedge and a compass. A straightedge is used to draw a straight line, and a compass is used to measure and transfer distances to create additional parallel lines.

1. The ratio for sin x in the trigonometry will be 12/13.
The ratio for cos x in the trigonometry will be 5/13.
The ratio for tan x in the trigonometry will be 12/5
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used extensively in various fields, including physics, engineering, and astronomy.
The three primary functions in trigonometry are sine, cosine, and tangent. These functions relate the ratios of the sides of a right triangle to its angles.
The sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse. The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse. The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
Trigonometry also involves inverse functions, such as the arcsine, arccosine, and arctangent. These functions are used to find the angle whose sine, cosine, or tangent is a given value.

taylor has enough money to buy either 90 granola bars or 78 pop tarts. After returning from the atore, taylor has no money, 75 granola bars and p pop tarts
Using equations, we can find that the number of pop tarts that Taylor has with him, p = 13.
Define equations?An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values. as in 3x + 5 = 15, for example. There are many different types of equations, including linear, quadratic, cubic, and others.
Let the cost of one granola bar = x.
Let the cost of one pop tart = y.
Now, assume Taylor had money, m.
So, as per the question:
90x = m
⇒ x = m/90
78y = m
⇒ y = m/78
75x + py = m
Substituting the values of x and y:
⇒ 75 × m/90 + p × m/78 = m
⇒ 75m/90 + pm/78 = m
⇒ (5850m + 90pm) / 7020 = m
⇒ 5850m + 90pm = 7020m
⇒ 90pm = 7020m - 5850m
⇒ 90pm = 1170m
⇒ p = 1170m/90m
⇒ p = 13.
Therefore, the number of pop tarts, p = 13.

A graph is a visual representation or diagram that displays facts or values in an organised manner in mathematics. The points on a graph are typically used to depict the relationships between two or more things.
A graph in discrete mathematics is made up of vertices, which are groups of points, and edges, which are the connections between those vertices. There are numerous different types of graphs besides linked and disconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs.

The function g(x) is shown on the graph.
The graph shows an upward opening parabola with a vertex at negative 4 comma 3, a point at negative 6 comma 7, and a point at negative 2 comma 7.
What is the equation of g(x) in vertex form?
g(x) = (x − 4)2 − 3
g(x) = (x − 4)2 + 3
g(x) = (x + 4)2 − 3
g(x) = (x + 4)2 + 3
Step-by-step explanation:
Vertex at -4,3 would result in vertex form of parabola
g(x) = (x+4)^2 + 3
How many years will it take $6,000 invested at 8% interest to earn $1,680?
Answer:
We can use the formula for simple interest to solve this problem:
I = Prt
where I is the amount of interest earned, P is the principal (the initial amount invested), r is the annual interest rate (as a decimal), and t is the time (in years).
In this problem, we know that P = $6,000, r = 0.08, and I = $1,680. We want to find t, the time required to earn $1,680 in interest.
Substituting these values into the formula, we get:
$1,680 = $6,000 x 0.08 x t
Simplifying and solving for t, we get:
t = $1,680 / ($6,000 x 0.08) = 3.5 years
Therefore, it will take 3.5 years for $6,000 invested at 8% interest to earn $1,680 in interest.

Look at the equations below. Find a pair of
equations whose lines are perpendicular.
Click on the correct answer.
y = x +6;y = −6x + 4
y = 5x-4; y = 5x +5
y = -5x + 6; y = -10x + 4
1
y=-x-4; y = −5x+5
The equations of line that are perpendicular to each other are:
A: y = (1/6)x + 6; y = -6x + 4
How to find perpendicular equations?The general formula for the equation of a line in slope intercept form is:
y = mx + c
where:
m is slope
c is y-intercept
Now, for two equations to be perpendicular, it means that their slope must be negative reciprocals of each other. Thus:
Looking at the equations, we can say the only ones that have slopes that are negative reciprocals of each other is option A.
