Triangle PQR is rotated 180 degrees clockwise about the origin to produce the image Triangle P’Q’R’. Which of the following statements is TRUE abóyate Triangle P’Q’R’.
Answer:
Step-by-step explanation:
We get triangle PQR by plotting the point P (1, 4), Q (3, 1), R (2, -1) on the graph paper when rotated through 180° about the origin. The new position of the point is: P (1, 4) → P' (-1, -4) Q (3, 1) → Q' (-3, -1) R (2, -1) → R' (-2, 1) Thus, the new position of ∆PQR is ∆P’Q’R’.

The equation of the form y = c + b logₐX is y = -3 + 3 Log₃X
How to derive the equation?Recall that Slope-intercept form of a linear equation is where one side contains just “y”. It looks like y = mx + “b” where “m” and “b” are numbers. This form of the equation is very useful because the coefficient of "x" (the "m" value) is the slope of the line and the constant (the "b" value) is the y-intercept at (0, b)
The equation of the line is give as
y-y₁ = m(x-x₁) + c
Where m is the slope and c is the intercept
This implies that
y -3 = m(x -2)
But slope is given as m = (y₂ - y₁)/(x₂-x₁)
m = (9-3)/ 4-2) = 6/2 = 3
Then, the equation is
y - 3 = 3x - 6
Collecting like terms we have
y = 3x -6+3
y = 3x -3
Writing this in the form y = c + b logₐX
y = -3 + 3 Log₃X

The equation of the function in the form y = c + b log_a(x) is y = logₓ2
Calculating the equation of the functionWe can start by assuming that the equation is of the form y = c + b log_a(x), where c and b are constants and a is the base of the logarithm.
Using the point (2, 3), we get:
3 = c + b log_a(2)
Using the point (4, 9), we get:
9 = c + b log_a(4)
Simplifying the second equation using the logarithmic identity
loga(4) = 2 loga(2), we get:
3 + 2b loga(2) = 9
Substituting the first equation into this one, we get:
3 = 9 - 2b loga(2)
So, we have
-6 = - 2b loga(2)
Divide
bloga(2) = 3
So, we have
b = 3 / log_a(2)
Substituting this value of b into the first equation, we get:
3 = c + b log_a(2)
3 = c + 3 / log_a(2) * log_a(2)
So, we have
c = 0
Therefore, the equation of the curve is y = (2 / log_a(2)) log_a(x)
We can simplify this equation by using the logarithmic identity log_a(x^b) = b log_a(x):
y = 2 log_a(x) / log_a(2)
y = (2 / log(2)) log(x)
So the final equation is:
y = logₓ2

Find the critical value t
The answer of the given question based on the Critical value is , , the critical value to for the confidence level c = 0.99 and sample size n = 22 is 2.819.
What is Critical value?In statistics, the critical value is a value that is used to determine whether to reject the null hypothesis in a hypothesis test. It is based on the chosen level of significance, which is the maximum probability of making a Type I error (rejecting a true null hypothesis). The critical value is determined by the sampling distribution of the test statistic, which is often a t-statistic or z-statistic, depending on the test and the characteristics of the population being studied.
To find the critical value t for a 99% confidence level and a sample size of 22, we need to use a t-distribution table or a calculator.
Using a t-distribution table with 21 degrees of freedom (n-1), we find that the critical value for a 99% confidence level is approximately 2.819.
Therefore, critical value for confidence level c = 0.99 and sample size n = 22 is 2.819 (rounded to nearest thousandth).

We need to find a number which increased by 3.5 of itself equals 621.
Let that number be x.
x increased by 3.5 of itself equals 621 implies x+ 3.5x = 621.
x(1+3.5) = 621
x(4.5) = 621
x = 621/4.5
x = 138
Therefore the required number is 138.
Answer: 138
Step-by-step explanation:
We need to find a number which increased by 3.5 of itself equals 621.
Let that number be x.
x increased by 3.5 of itself equals 621 implies x+ 3.5x = 621.
x(1+3.5) = 621
x(4.5) = 621
x = 621/4.5
x = 138

A wall is 2000 sq ft. A gallon of paint covers 400 sq ft. Complete the conversion factor: 1 gallon / ? sq ft
To cover a 2000 sq ft wall, we will need 5 gallons of paint.
what is area?
Area is the measure of the size of a two-dimensional surface or region, expressed in square units. It is a fundamental concept in geometry and is used to quantify the amount of space inside a shape, such as a square, rectangle, triangle, or circle. The unit of measurement for area varies depending on the system used, but in the International System of Units (SI), the standard unit of area is the square meter (m²). In everyday life, we often use other units of area such as square feet, square inches, or square centimeters.
To find the conversion factor, we need to divide the number of square feet by the number of square feet covered by one gallon of paint:
Conversion factor = 1 gallon / (400 sq ft/gallon)
So, for a wall that is 2000 sq ft, we can use this conversion factor to find the number of gallons of paint needed:
Number of gallons = (2000 sq ft) / (400 sq ft/gallon) = 5 gallons
Therefore, to cover a 2000 sq ft wall, we will need 5 gallons of paint.

f(x) = x2 + 4; interval [0, 5]; n = 5; use left endpoints
Therefore, the Left Riemann Sum for this function, interval, and number of subintervals is 50.
The left endpoint rule is what?The top-left corner of these rectangles touched the y=f(x) curve. In other words, the value of f at the subinterval's left endpoint determined the height of the rectangle over that subinterval. This technique is called the left-endpoint estimate because of this.
With left endpoints and n = 5 subintervals, we may use the Left Riemann Sum formula to approximate the area under the curve of f(x) = x2 + 4 over the range [0, 5]:
Left Riemann Sum = ∑[i=1 to n] f(x_i-1) Δx
In this case, a = 0, b = 5, n = 5, and we will use the left endpoints, so:
Δx = (5 - 0)/5 = 1
Using the left endpoints, the subintervals and their left endpoints are:
[0,1],[1,2],[2,3],[3,4],[4,5]
[tex]so,\; x_0 = 0, x_1 = 1, x_2 = 2, x_3 = 3, x_4 = 4.[/tex]

given FH is a diameter , then
arc FH = 180°, that is
FG + GH = 180°
103° + GH = 180° ( subtract 103° from both sides )
GH = 77°
the central angle HIG is equal to the arc that subtends it GH , so
∠ HIG = 77°
∠ EIF and ∠ HIG are vertically opposite angles and are congruent , then
∠ EIF = 77°
the arc EF subtends the central angle EIF , so
EF = 77°
the sum of the 3 arcs = 180° , that is
HD + DE + EF = 180
15 + 18x - 2 + 77 = 180
18x + 90 = 180 ( subtract 90 from both sides )
18x = 90 ( divide both sides by 18 )
x = 5
then arc DE = 18x - 2 = 18(5) - 2 = 90 - 2 = 88°
Convert to polar form
Y=x^2-64/16
To convert the expression, Y=x^2-64/16 into the polar form, we would have: r = 2 / √(sin^2θ + cos^2θ).
How to convert into the polar formThe polar form of a mathematical expression is a way of representing complex numbers using their magnitude and angle.
For a complex number z = a + bi, where a and b are real numbers, its polar form is given by z = r(cosθ + i sinθ), where r is the magnitude of z and θ is the angle that z makes with the positive real axis.
So, for the given expression, the polar form can be converted this way:
r^2 sin^2θ = r cos^2θ - 4
r^2(sin^2θ + cos^2θ) = 4
r = 2 / √(sin^2θ + cos^2θ)
Therefore, the polar form is r = 2 / √(sin^2θ + cos^2θ).

Brenda is fishing from a small boat. Her fishing hook is 12 feet below her, and a fish is swimming at the same depth as the hook, 16 feet away. How far away is Brenda from the fish?
Answer:
We can use the Pythagorean theorem to solve this problem. Let's call the distance Brenda is away from the fish "x". Then, we have a right triangle with legs of length 12 and x, and a hypotenuse of length 16. So:
x^2 + 12^2 = 16^2
Simplifying:
x^2 + 144 = 256
x^2 = 112
Taking the square root of both sides:
x ≈ 10.6 feet
Therefore, Brenda is approximately 10.6 feet away from the fish.

Hence, the correct answer is B. y = {11, 13, 17, 25}.
Matt can save $225 per month that he puts into a savings
account earning 5% annual interest. How much will he have
saved after 2 years?
Answer:
FV ≈ $5,673.56
Step-by-step explanation:
To calculate the total amount that Matt will have saved after 2 years of saving $225 per month at an annual interest rate of 5%, we can use the formula for the future value of an annuity:
FV = P * (((1 + r/12)^(n*12) - 1) / (r/12))
where:
FV is the future value of the annuity
P is the periodic payment (in this case, $225 per month)
r is the interest rate per year (in this case, 5%)
n is the number of years (in this case, 2)
Substituting the given values, we get:
FV = $225 * (((1 + 0.05/12)^(2*12) - 1) / (0.05/12))
Using a calculator, we get:
FV ≈ $5,673.56
Therefore, after 2 years of saving $225 per month at an annual interest rate of 5%, Matt will have saved approximately $5,673.56.

What is Pythagoras theorem?A basic mathematical theorem relating to the sides of a right-angled triangle is known as Pythagoras' theorem. The square of the length of the hypotenuse, the side that faces the right angle, is said to be equal to the sum of the squares of the lengths of the other two sides, known as the legs, in a right triangle.
This can be written in mathematical notation as:
c² = a² + b²
where c is the length of the hypotenuse, and a and b are the lengths of the legs of the right triangle.
In this case, we can consider the straight line between Maria's house and Landon's house as the hypotenuse of a right triangle, with the distances they walked as the other two sides. We can use the distance formula to find the lengths of those sides:
Distance walked by Maria = √(9² + 3²) = √90 ≈ 9.49 blocks
Distance walked by Landon = √(5² + 7²) = √74 ≈ 8.60 blocks

Ian has a deck that measures 20 feet by 10 feet. He wants to increase each dimension by equal lengths so that its area is tripled. By how much should he increase each dimension?
Answer:
10 feet
Step-by-step explanation:
Let's start by finding the current area of the deck:
Area = length x width = 20 ft x 10 ft = 200 sq ft
If Ian increases each dimension by the same amount, let's call this amount "x", then the new dimensions of the deck will be:
Length = 20 ft + x
Width = 10 ft + x
The new area of the deck will be:
New Area = (20 ft + x) x (10 ft + x)
We know that Ian wants the new area to be triple the original area of 200 sq ft, so:
New Area = 3 x 200 sq ft
New Area = 600 sq ft
Substituting this into the equation above and solving for "x", we get:
(20 ft + x) x (10 ft + x) = 600 sq ft
200 + 30x + x^2 = 600
x^2 + 30x - 400 = 0
(x + 40) (x - 10) = 0
We discard the negative solution, and we get:
x = 10 ft
Therefore, Ian should increase each dimension by 10 feet to triple the area of his deck.
To confirm, we can check the original area of the deck which is 20 ft x 10 ft = 200 sq ft.
If Ian increases each dimension by 10 feet, the new dimensions of the deck will be 30 ft x 20 ft. The new area of the deck will be 30 ft x 20 ft = 600 sq ft. This is triple the original area of the deck (200 sq ft), which is what we wanted to achieve.
Therefore, increasing each dimension by 10 feet will triple the area of the deck as required.
Ian should increase both the sides by 10 feet each.
This is a simple mathematics problems related to the topic of mensuration.
Firstly we calculate the current area of the deck:
Area of the deck (rectangle) = l x b
Area of the deck (rectangle) = 20 x 10
Area of the deck (rectangle) = 200 square feet
Since Ian wants to triple the area of the deck, the required area is 600 square feet.
We now look at pairs of numbers multiplying which will give us 600:
(1,600) (2,300) (3,200) (4,150) (5,120) (6,100) (8,75) (10,60) (12,50) (15,40) (20,30) (25,24)
Out of the above pairs only one pair fulfils Ian's criteria to increase the length and breadth of the deck by equal measure, i.e., (20,30). So, Ian should increase the length and breadth of his deck by 10 feet each.

The volume of a cube is increasing at a rate of 56 in^3/sec. At what rate is the length of each edge of the cube changing when the edges are 4 in. long? (Recall that for a cube,
V = x^3.)
Answer:
Step-by-step explanation:
Let's denote the volume of the cube as V and the length of each edge as x. Given that the volume of a cube is V = x^3, we can find the rate at which the length of each edge is changing.
We're given that the rate of change of the volume is dV/dt = 56 in³/sec. We want to find the rate of change of the length of each edge, which is dx/dt, when the length of each edge is 6 inches.
First, we differentiate the volume equation with respect to time t:
V = x^3
dV/dt = d(x^3)/dt
Using the chain rule:
dV/dt = 3x^2 * (dx/dt)
Now, we know that dV/dt = 56 in³/sec and x = 6 in. Plugging these values into the equation, we get:
56 = 3 * (6)^2 * (dx/dt)
Solving for dx/dt:
56 = 108 * (dx/dt)
dx/dt = 56 / 108
dx/dt ≈ 0.5185 in/sec (rounded to four decimal places)
So, the rate at which the length of each edge is changing is approximately 0.5185 inches per second when the edges are 6 inches long.

Step-by-step explanation:
from
A=p[1+r/100]^n
where
A is amount
p is principal
r is rate interest
n number of interist period
now,
15000=p[1+12/100]^8
15000/1.12^8 =p×1.12^8/1.12^8
p=6058.24
p=6058)
: .you should invest 6,058
The amount to be invested initially if you want to have fifteen thousand dollars after nine years is $3947.18.
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
We are given that:
A=15000
r=0.12
t=9
We need to find P. You can do this by rearranging the formula:
P=ertA
Then plug in the given values and use a calculator:
P=e0.12×915000
P≈3947.18
Therefore, by the given interest rate the answer will be $3947.18.
