Arock was dropped from the top of a building. the function that describes the height after it was dropped is f(x)=64-16x^2. what are the zeros of the function and what do they mean?

Step-by-step explanation:

f(x) = height = 64 - 16x^2 = 0.

16x^2 = 64

x^2 = 4

x = 2, -2.

The zero x = 2 means that the height after time 2 is 0. This corresponds to the time of the rock hitting the ground.

The -2 can be ignored.

answer: list the statements and i will follow up!

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
