Answer:
40
Step-by-step explanation:
5√64 = 5 x 8 = 40
<span>h = -8t² + 40t
dh/dt = 0
⇒ d/dt(</span><span>-8t² + 40t) = 0
⇒ -16t + 40 = 0
⇒ 16t = 40
⇒ t = 40/16 = 2.5s
So it takes 2.5 seconds to reach highest point
h = -8×2.5² + 40×2.5 = -50 + 100 = 50
Ordered pair: (h,t) = (50,2.5)

Answer:
The answer is 7,540 to the nearest tenth. If I'm wrong put it in the comments olease
-7(2)+y=60
-14+y=60
y=60+14
Y=74
