Which of the following is the best estimate
of the square root of 90 ?
a. 9.1
b. 9.4
C. 9.7

Answer:

y = 2(x - 9)² - 1

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (9, - 1 ) , thus

y = a(x - 9)² - 1

To find a substitute (7, 7 ) into the equation

7 = a(7 - 9)² - 1 ( add 1 to both sides )

8 = 4a ( divide both sides by 4 )

2 = a , then

y = 2(x - 9)² - 1

The surface area of the rectangular prism with dimensions [tex]2[/tex] cm by [tex]2[/tex]cm by [tex]5[/tex] cm is [tex]48 cm^2.[/tex]

The surface area of a rectangular prism is [tex]2(lw+wh+lh)[/tex], where [tex]l[/tex] is length, [tex]w[/tex] is width, and [tex]h[/tex] is height.

A rectangular prism has dimensions of [tex]2[/tex] cm by [tex]2[/tex] cm by [tex]5[/tex] cm.

Let [tex]l=2[/tex] cm, [tex]w=2[/tex] cm and [tex]h=5[/tex] cm.

i dont have an explanation its just C

Answer:

the answer is 35.

Step-by-step explanation:

So first you look for 75 on the x-axis because this represents the number of people in attendance. 75 would be the line between 50 and 100. Then you need to follow the 75 line up until you see the point that the graphed line intersects the "75 line". When you drag you finger from that point over to the y-axis, you see the number of recyclables is about 35.

If there were 35 cows and the ratio for cows to horses is 7:4, then there would be 20 horses because 35 divided by 5 is 7 and 20 divided by 5 is 4.

g(3) = 5(3) - 9

= 15 - 9 = 6

Answer : g(3) = 6

In the function [tex]g(x) =5x-9[/tex], the value of g(3) is equal to 6.

Given the following function:

To determine the value of g(3):

In this exercise, you're required to find the value of the given function when g of x is equal to 3.

Therefore, we would substitute the value of x into the given function.

Substituting the value of x into the function, we have:

[tex]g(x) =5x-9\\\\g(3) =5(3)-9\\\\g(3) =15-9\\\\g(3) =6[/tex]

g(3) = 6

Answer:

Maximum returns = $1,980,000

x = Homeowner loans = $17,600,000

y = Auto loans = $4,400,000

Madison should extend $17,600,000 in home owners loans and $4,400,000 in auto loans in order to have a maximum return of $1,980,000

Step-by-step explanation:

From the question we are told that:

Madison Finance has a total of $22 million earmarked for homeowner loans and auto loans, where x is homeowner loans in millions of dollars and y is auto loans in millions of dollars.

On the average, homeowner loans have a 8% annual rate of return, whereas auto loans yield a 13% annual rate of return.

We have the equation:

Maximum Return = 8% × x + 13% × y

= 0.08x + 0.13y

We are told in the question that

Management has also stipulated that the total amount of homeowner loans should be greater than or equal to 4 times the total amount of automobile loans.

Hence,

x ≥ 4y

So:

x + y = $22,000,000

4y + y = $22,000,000

5y = $22,000,000

y = $22,000,000/5

y = 4,400,000

x = 4y

x = 4(4,400,000)

x = 17,600,000

Maximum Return = 0.08x + 0.13y

= 0.08 × 17,600,000 + 0.13 × 4,400,000

= $1,980,000

Therefore, Madison should extend $17,600,000 in home owners loans and $4,400,000 in auto loans in order to have a maximum return of $1,980,000
