3√5a-8√/35a2
Answers
3√(5a) - 8√(a) / 35a^2
To simplify this expression, we can first separate the two terms in the numerator:
3√(5a) / 35a^2 - 8√(a) / 35a^2
We can then simplify each term separately. For the first term:
3√(5a) / 35a^2 = √(5a) / (35a^2/3)
We can simplify the denominator by using the rule that (a^m)^n = a^(mn):
35a^2/3 = (5a^2/3) * 7 = (a^(2/3))^5 * 7
So the first term simplifies to:
√(5a) / (a^(2/3))^5 * 7
For the second term:
8√(a) / 35a^2 = 8a^(1/2) / (35a^2)
We can simplify the denominator by using the rule that a^-m = 1/a^m:
35a^2 = 5 * 7 * a^2 = a^-2 * 5 * 7
So the second term simplifies to:
8a^(1/2) / (a^-2 * 5 * 7)
Now we can combine the two terms by finding a common denominator:
√(5a) / (a^(2/3))^5 * 7 - 8a^(1/2) / (a^-2 * 5 * 7)
The common denominator is (a^(2/3))^5 * 5 * 7:
√(5a) * 5 * 7 / (a^(2/3))^5 * 5 * 7 - 8a^(1/2) * (a^(2/3))^5 * 5 * 7 / (a^-2 * 5 * 7) * (a^(2/3))^5 * 5 * 7
Simplifying each term, we get:
35√(5a) / 5a^2 - 40a^(5/2) / 5a^3
Now we can simplify further by factoring out a common factor of 5a^(5/2):
5a^(5/2) * (7√(5a) - 8) / 5a^3
The 5's cancel out, and we can remove the common factor of 5a^(5/2) to get:
(7√(5a) - 8) / a^(3/2)
So the simplified expression is:
(7√(5a) - 8) / a^(3/2)
the area of Rectangle is 112 in sq. if the height is 8 in, what is the base length
Answers
Answer:
14cm
Step-by-step explanation:
112÷8=14
base length=14cm
Answer:
To find the base length of a rectangle, given its area and height, you can use the formula for calculating the area of a rectangle, which is:
Area = Length x Width
In this case, you are given that the area is 112 square inches and the height is 8 inches. Let's denote the base length as "x" inches.
So, the equation for the area of the rectangle becomes:
112 = x * 8
To solve for "x", you can divide both sides of the equation by 8:
112 / 8 = x
x = 14
Therefore, the base length of the rectangle is 14 inches.

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.
Answers
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.

Find the exact value, cos(-pi/12). Use the half angle strategy.
Answers
Using the half angle formula, cos(-π/12) = ±√[2 + √3]/4]
What is the half angle formula?The half angle formula for cosine is cosФ/2 = ±√[(1 + cosФ)/2]
Since we want to find the value of cos(-pi/12) using the half angle formula, we have that cosФ/2 = cos(-π/12)
⇒ Ф/2 = -π/12
⇒ Ф = -π/12 × 2
⇒ Ф = -π/6
So, substituting this into the equation, we have
cosФ/2 = ±√[(1 + cosФ)/2]
cos(-π/6)/2 = ±√[(1 + cos(-π/6))/2]
= ±√[(1 + cos(π/6))/2]
Now, we know that cos(π/6) = √3/2
So, substituting this into the equation, we have that
cos(-π/6)/2 = ±√[(1 + cos(π/6))/2]
cos(-π/12 = ±√[(1 + cos(π/6))/2]
= ±√[(1 + √3/2)/2]
= ±√[[2 + √3]/2)/2]
= ±√[[2 + √3]/2 × 2]
= ±√[2 + √3]/4]
So, cos(-π/12) = ±√[2 + √3]/4]

Is 40, –40, 16, or –16 the solution of the equation 28=d−12?
Answers
Answer:
To check whether 40, -40, 16, or -16 is the solution of the equation 28 = d - 12, we can substitute each value into the equation and see if it results in a true statement.
When we substitute 40 into the equation, we get:
28 = 40 - 12
Simplifying, we get:
28 = 28
This is a true statement, so 40 is a solution of the equation.
When we substitute -40 into the equation, we get:
28 = -40 - 12
Simplifying, we get:
28 = -52
This is not a true statement, so -40 is not a solution of the equation.
When we substitute 16 into the equation, we get:
28 = 16 - 12
Simplifying, we get:
28 = 4
This is not a true statement, so 16 is not a solution of the equation.
When we substitute -16 into the equation, we get:
28 = -16 - 12
Simplifying, we get:
28 = -28
This is not a true statement, so -16 is not a solution of the equation.
Therefore, the only solution of the equation 28 = d - 12 is d = 40.
An average newspaper contains at least 9 pages and at most 46 pages. How many newspapers must be collected to be certain that at least two newspapers have the same number of pages?
Answers
We need to collect 46 newspapers to be certain that at least two newspapers have the same number of pages.
What is the minimum number of newspapers needed to guarantee that two newspapers have the same number of pages?According to the Pigeonhole Principle, if we have n+1 pigeons and n holes, then there must be at least one hole with two or more pigeons. Similarly, if we have n+1 newspapers with n possible page counts, then there must be at least one page count that appears in two or more newspapers.
In this case, we have a range of 38 possible page counts (46 - 9 + 1), so we need at least 39 newspapers to guarantee that each possible page count appears in at least one newspaper.
However, to guarantee that at least two newspapers have the same number of pages, we need one more newspaper than the number of possible page counts, so we need a total of 46 newspapers. Therefore, if we collect 46 newspapers, we can be certain that at least two of them have the same number of pages.

Give an example of a classification based on both side length and angle measure that is unnecessary and explain why.
Answers
By answering the presented question, we may conclude that As a result, adding the isosceles triangle categorization is superfluous and redundant in this circumstance.
What is triangle?A triangle is a polygon since it has three sides and three vertices. It is a basic geometric shape. Triangle ABC refers to a triangle with the vertices A, B, and C. In Euclidean geometry, a single plane and triangle are obtained when the three points are not collinear. If a triangle has three sides and three corners, it is a polygon. The triangle's corners are the spots where the three sides meet. The sum of three triangle angles equals 180 degrees.
An isosceles triangle has two sides of equal length, but a right triangle has one angle that measures 90 degrees. As a result, an isosceles right triangle is one with two equal-length sides and one 90-degree angle.
The Pythagorean theorem states that in any right triangle, the two legs (the sides next to the right angle) are always of equal length. Hence, if we know that a triangle has one 90-degree angle and two equal-length sides, we already know that it is a right triangle and that the two legs are equal. As a result, adding the isosceles triangle categorization is superfluous and redundant in this circumstance.

The x-axis is where the circle centre is located. Three units make up the circle's radius. This circle's radius coincides with the radius of the circle whose equation is x² + y² = 9.
What is the circle's equation when its centre is on the x-axis?The y coordinate of a circle's centre will be 0 if the circle's centre is on the x-axis. The circle's equation will therefore have the generic form x2 + y2 + 2gx + c = 0, where g and c are constants.
Circle's standard equation is written as:
x²+y²+2gx+2fy+C=0
Centre is (-g, -f)
radius = √g²+f²-C
Given a circle whose equation is : x²+y²-2x-8=0
Get the centre of the circle
2gx = -2x
2g = -2
g = -1
Similarly, 2fy = 0
f = 0

f(x) = 2x^2 + x + 4
Answers
We see that f(-1) = g(1) = 5. Therefore, the solution to the system of equations is x = -1.
Describe System of equation?A system of equations is a set of two or more equations that are to be solved simultaneously. Each equation in the system represents a relationship between variables, and the solution to the system is the set of values for the variables that satisfy all of the equations in the system.
One way to solve a system of equations is by substitution. We can solve one of the equations for one of the variables in terms of the other variable, and then substitute that expression into the other equation to get an equation in one variable. We can then solve that equation for the variable, and use that value to find the value of the other variable.
Another way to solve a system of equations is by elimination. We can add or subtract the equations in the system to eliminate one of the variables, and then solve for the other variable. We can then use that value to find the value of the eliminated variable.
To find a solution to the system of equations that includes the quadratic function f(x) and the linear function g(x), we need to find the value of f(x) for each value of x and compare it to the corresponding value of g(x). If f(x) and g(x) are equal for any value of x, then that value is a solution to the system.
Substituting each value of x into the quadratic function f(x), we get:
f(-2) = 2(-2)² + (-2) + 4 = 10
f(-1) = 2(-1)² + (-1) + 4 = 5
f(0) = 2(0)² + 0 + 4 = 4
f(1) = 2(1)² + 1 + 4 = 7
f(2) = 2(2)² + 2 + 4 = 14
Comparing these values to the corresponding values of g(x), we see that f(-1) = g(1) = 5. Therefore, the solution to the system of equations is x = -1.

A = 2000(1 + 0.05/12)^(12*7) = $2,905.03
d) If interest is compounded continuously:
A = Pe^(rt) = 2000e^(0.05*7) = $2,938.36
Therefore, the amount in the bank after 7 years increases as the compounding frequency increases, and it is highest when interest is compounded continuously.

Step-by-step explanation:
Angel made a table runner that has an area of 80 square inches. The length and width of the table runner are whole numbers. The length is 5 times greater than the width. What are the dimensions of the table runner?
Answers
the dimensions of the table runner are [tex]20[/tex] inches in length and [tex]4[/tex] inches in width.
What are the dimensions?Let's denote the width of the table runner as "w" inches. Since the length is 5 times greater than the width, the length would be 5w inches.
The area of a rectangle is calculated by multiplying its length by its width. Given that the area of the table runner is 80 square inches, we can set up the following equation:
Length × Width = Area
[tex](5w) \imes w = 80[/tex]
Simplifying further:
[tex]5w^2 = 80[/tex]
Dividing both sides by 5:
[tex]w^2 = 16[/tex]
Taking the square root of both sides:
w = ±4
Since the width cannot be negative in this context, we discard the negative value. Therefore, the width (w) of the table runner is [tex]4[/tex] inches.
Substituting this value back into the equation for length:
Length [tex]= 5w = 5 \times 4 = 20[/tex] inches
So, the dimensions of the table runner are [tex]20[/tex] inches in length and 4 inches in width.
