H(t) = -16t² + 16 t + 480
Factor out -16
-16(t² - t - 30)
t² - t - 30
(t + 5)(t - 6) ⇒ t(t-6) + 5(t-6) ⇒ t² -6t + 5t - 30 ⇒ t² - t - 30
t + 5 = 0 t - 6 = 0
t = -5 t = 6
The value of t is either -5 or 6 however time can't be measured in negative form; then, it took Rose 6 seconds to hit the water.
There is no picture of the graph
Answer: 4
Step-by-step explanation:
We know that a plane is 2 dimensional surface that extends infinitely far.
The number of points required to define a plane = 3
Here , we have 4 points A, B, C, and D.
So, the number of possible combinations of 3 points to make a plane from 4 points = 
[
]
Hence, the greatest number of planes determined using any three of the points A, B, C, and D if no three points are collinear = 4.
