The correct model of the height of rocket above water is;
h(t) = -16t² + 96t + 112
Answer:
time to reach max height = 3 seconds
h_max = 256 ft
Time to hit the water = 7 seconds
Step-by-step explanation:
We are given height of water above rocket;
h(t) = -16t² + 96t + 112
From labeling quadratic equations, we know that from the equation given, we have;
a = -16 and b = 96 and c = 112
To find the time to reach maximum height, we will use the vertex formula which is; -b/2a
t_max = -96/(2 × -16)
t_max = 3 seconds
Thus, maximum height will be at t = 3 secs
Thus;
h_max = h(3) = -16(3)² + 96(3) + 112
h_max = -144 + 288 + 112
h_max = 256 ft
Time for it to hit the water means that height is zero.
Thus;
-16t² + 96t + 112 = 0
From online quadratic formula, we have;
t = 7 seconds

Translate, in math, is just a fancy word for "change" or "move". We're changing (-5, 2) using x + 3 and y - 1. If the x value is -5, what is x + 3?
(-5) + 3 = -2
And for the y - 1?
(2) - 1 = 1.
Your answer is P'(-2, 1)

Answer:
-1/3
Step-by-step explanation:
slope = m = rise/run = (difference in y)/(difference in x)
m = (4 - 2/(-3 - 3)
m = 2/(-6)
m = -1/3
Answer:
this equation would be 2(c-8)=3
