Me either just ask your teacher or use the app Socratic
<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)
</span>
6 + 28 + 4x +28
34 +28 + 4x
62 + 4x?
Not quite sure if that was what you were looking for
Answer:
All of the following statements are true because the products, three or four numbers, remain the same regardless of how the numbers are grouped.
180°=triangle
360°=quadrangle
180°*34+180=6300°
