The cost for renting a weed trimmer varies directly with the number of hours used. A weed trimmer rented for 5 hours costs $32.5

0.Which choice shows the direct variation equation and the amount of rent for 8 hours in this situation?
A y = $6.5x, y = $52.00
B y = $32.5x, y = $260.00
C y = $5x, y = $40.00
D y = $8x, y = $64.00

Let the cost for renting be y and the number of hours be x
then:
y=kx
where:
k is the constant of proportionality
k=y/x
y=$32.5 when x=5 hours
thus;
k=32.5/5
k=6.5
hence the equation is:
y=6.5x
thus the value of y when x=8 hours will be:
y=6.5(8)=$52
Answer:'

<span>A y = $6.5x, y = $52.00</span>

Elizabeth bought lemons (l) and apples (a). Each apple costs 35¢ and each lemon costs 15¢. All together, she bought 17 lemons an
Zina [86]

Step-by-step explanation:

<u>Given:</u>

  • Lemons - l and apples - a
  • a = 35¢, l = 15¢
  • Number of apples and lemons = 17
  • Cost of lemons and apples = $3.95 = 395¢

<u>System as per question:</u>

  • a + l = 17
  • 35a + 15l = 395

Or

  • a + l = 17
  • 0.35a + 0.15l = 3.95

The average rate of change of function g(x)=5(2)^{x} from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.

The correct option is (A).

What is the average rate of change of a function?

The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function.

Using function notation, we can define the Average Rate of Change of a function f from a to b as:

                                     rate(m) = \frac{f(b)-f(a)}{b-a}

The given function is  g(x) = 5(2)^{x},

Now calculating the average rate of change of function from x = 1 to x = 2.

                               m = \frac{g(b)-g(a)}{b-a}\\ m = \frac{g(2)-g(1)}{2-1}\\\\m=\frac{5(2)^{2}-5(2)^1}{2-1}\\ m=\frac{10}{1} \\m=10

Now, calculate the average rate of change of function from x = 3 to x = 4.

                                 m = \frac{g(b)-g(a)}{b-a}\\ m = \frac{g(4)-g(3)}{4-3}\\\\m=\frac{5(2)^{4}-5(2)^3}{4-3}\\ m=\frac{40}{1} \\m=40

The jump from m = 10 to m = 40 is "times 4".

So option (A) is correct.

Hence, The average rate of change of function g(x)=5(2)^{x} from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.

If f(x) = 2x2 - x, find f(-3).
forsale [732]

f(x)=2x^2-x


Substitute the value of x = -3 to the equation:


f(-3)=2(-3)^2-(-3)=2(9)+3=18+3=21

The dimensions of a cube are doubled. The volume of the enlarged cube is how many times the volume of the original cube?
Elza [17]
The volume is multiplied by 8. For example if you have a 1x1x1 cube the volume is 1. If you have a 2x2x2 cube the volume is 8. If you have a 4x4x4 the volume is 64.
