Hi can you me on #19 i don’t understand the steps can you write it out in examples. you so much

4800

Step-by-step explanation:

Given the function

y = 75 ×

x is the number of 15 year periods

45 years has 3 15 year periods , thus x = 3

Substitute x = 3 into the function and solve for y

y = 75 × 4³ = 75 × 64 = 4800

There will be 4800 foxes after 45 years

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
