Answer:
-39991'
Step-by-step explanation:
We require the sum of 7 terms of the G.S. -1, 6, -36 .....
The common ratio r = 6/-1 = -6 and the first term = -1.
Sum of n terms = a1 . (r^n - 1) / (r - 1)
Sum of 7 terms = -1 * (-6)^7 - 1) / (-6 - 1)
= -1 * 39991
= -39991 (answer).

Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :
We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0
So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.
