Answer:
Yes, see below.
Step-by-step explanation:
Convert the equation to vertex form to find the maximum height:
h = -16t2 + 64t + 5
= -16(t^2 - 4t) + 5
= -16 [(t - 2)^2 - 4] + 5
= -16( t - 2)^2 + 64 + 6
= -16(t - 2)^2 + 69.
So the maximum height the rock reaches is 69 feet.
This height is reached at 2 time seconds.

Answer:
x = -6
Step-by-step explanation:
The solution means to solve for x. To solve for "x", isolate the variable. This means to separate it from everything else. Do this using reverse operations in reverse BEDMAS order.
2/3 x + 5 = 1
2/3 x + 5 - 5 = 1 - 5 Subtract 5 from both sides
2/3 x = -4
(2/3 x) / (2/3) = (-4) / (2/3) Divide both sides by 2/3
x = (-4) / (2/3)
x = -6 Solution
