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.

Answer:
Second factor is (x - 2).
Step-by-step explanation:
The given polynomial is 3x² -10x + 8 has a factor (3x - 4) and we have to find the other factor.
Now we will factorize the given polynomial to get the other factor.
3x² - 10x + 8
[ Here 8×3 = 24( multiplication of constant term 8 and coefficient of highest degree term) and 6 + 4 = 10 ]
= 3x² - 6x - 4x + 8
= 3x(x - 2) - 4(x - 2)
= (3x -4)(x -2)
In this factorized form we get two factors as (3x -4) and (x -2).
Therefore the second factor is (x - 2).
