Answer:The number of seconds after rocket is released
Step-by-step explanation:
Given
The height of a rocket after it is released is modeled by
Here t represent the number of seconds after the rocket is released.
Initial velocity can also be determined by this equation by differentiating the 
w.r.t time
at t=o
thus initial velocity will be 32 units/s
Use the Pythagorean theorem a^2 + b^2 = c^2
45^2 + 80^2 = c^2
2025 + 6400 = c^2
c^2 = 8425
c = √8425
c = 91.787
Rounded to the nearest foot = 92 feet
I think it’s -8x + 24
Could be wrong, but I hope it helps :)
The answer to that is 439
let us represent the question with a diagram for better understanding.
Using Pythagoras theorem
![\begin{gathered} c^2=12^2+9^2 \\ c^2=144+81 \\ c=\sqrt[\square]{225} \\ c=15\text{ km} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20c%5E2%3D12%5E2%2B9%5E2%20%5C%5C%20c%5E2%3D144%2B81%20%5C%5C%20c%3D%5Csqrt%5B%5Csquare%5D%7B225%7D%20%5C%5C%20c%3D15%5Ctext%7B%20km%7D%20%5Cend%7Bgathered%7D)
The distance between the parents and grandparent house = 15 km
