Answer:
Therefore it will take
s for the object to reach the ground.
Step-by-step explanation:
Given function is
H(t) = -64 t²+169.
where H is height in feet, and t is time in second.
When the object touches the ground, the height of the object will be zero.
i.e H(t) = 0.
Therefore
H(t) = 0
⇒ -64 t²+169=0
⇒ -64 t²= -169
![\Rightarrow t^2= \frac{-169}{-64}](https://tex.z-dn.net/?f=%5CRightarrow%20t%5E2%3D%20%5Cfrac%7B-169%7D%7B-64%7D)
![\Rightarrow t^2= \frac{169}{64}](https://tex.z-dn.net/?f=%5CRightarrow%20t%5E2%3D%20%5Cfrac%7B169%7D%7B64%7D)
[ square root both sides]
![\Rightarrow t=\pm\frac{13}{8}](https://tex.z-dn.net/?f=%5CRightarrow%20t%3D%5Cpm%5Cfrac%7B13%7D%7B8%7D)
Time can not be negative.
Therefore ![t=\frac{13}{8} \ s](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B13%7D%7B8%7D%20%5C%20s)
Therefore it will take
s for the object to reach the ground.
The similarity statement would be that all three of them have the same sides
