Answer:
C. -2/3 < -0.8
F. -3/5 < -0.35
Therefor, -2/3 is less than -0.8.
And, -3/5 is also less than -0.35.
Also, you could turn the fractions into decimals to make your life easier for example, -3/5 into decimal form is -0.6.
And -2/3 into decimal form is -0.6666

Answer:
The ball will hit the ground at 10 seconds and its maximum height is 1024 feet.
Step-by-step explanation:
Height of a mountain, h = 90 feet
Upward velocity of a ball, u = 64 ft/s
Its height as a function of time can be written by using the second equation of motion as follows :
.....(1)
When it will hit the ground, f(x) = 0

It is quadratic equation.
t = -6 s and t = 10 s
Neglecting -6 seconds, the ball will hit the ground at 10 seconds.
For maximum height,
Put f'(x) = 0

Put t = 2 in equation (1)

Hence, the ball will hit the ground at 10 seconds and its maximum height is 1024 feet.
