The main assumption here is that the height at the water level is 0.
So, the answer is given by the solution to the equation
- 16t^2 + 16t + 480 = 0
To solve it, start dividing by -16 to get:
t^2 - t - 30 = 0.
Now factor the left side:
(t - ) (t + ) =0
Find two numbers that add - 1 and its product is -30
(t - 6 ) (t + 5 ) =0
That gives:
t - 6 = 0 ⇒ t = 6 seconds
The other result gives a time negative, which makes not sense for the problem.
Verify substituing 6 in the original equation:
h(6) = -16*6^2 + 16*6 + 480 = -576 + 96 + 480 = 0. Lo cual confirma nuestra solucion.
It toke Rose 6 seconds to hit the water.

Sub -58 and 24 in the equation
F(-58) = 3(-58) - 1
F (-58) = -175
F(24) = 3 (24) - 1
F (24) = 71

Answer:
C
Detailed explanation down below
Step-by-step explanation:
A bisector divides an angle in half, so we can say that:
7x - 27 = x + 57
7x = x + 84
6x = 84
x= 14
So now lets input this information
7 x 14 - 27 = m∠ LMO = 98 - 27 = 71°
14° + 57° = 71°
(Actually we didnt have to do this second equation because both angles should be equal.)
71° + 71° = 142°
So the answer is C : x=14° . m∠LMN = 142°
