Answer:
a. 144 ft
b. 5 s
Step-by-step explanation:
h = -16t² + 64t + 80
a. This is a parabola, so the maximum height is at the vertex.
t = -64 / (2 × -16)
t = 2
h = -16(2)² + 64(2) + 80
h = 144
The apple reaches a maximum height of 144 ft.
b. 0 = -16t² + 64t + 80
0 = t² − 4t − 5
0 = (t + 1) (t − 5)
t = -1 or 5
t must be positive, so it takes 5 seconds to reach the ground.
Interpreting the situation, it is found that Marjorie will have 240 left after paying her penalty.
---------------------
- When the piece lands on the red square, the penalty is equal to <u>30 times the sum they roll on two numbers.</u>
- Marjorie rolls 4 and 2, thus, the sum is 6.
- The penalty is of

- She currently has 420, the penalty removes 180, thus, she will have 420 - 180 = 240 left after paying her penalty.
