Answer:
The maximum height is reached after 3.75 seconds.
Step-by-step explanation:
Assuming the deceleration due to gravity is unaided by air resistance, gravity causes the ball to lose vertical speed at the rate of 32 ft/s every second. The initial vertical speed of 120 ft/s will decline to zero when t satisfies ...
... 120 ft/s - (32 ft/s²)t = 0
... (120 ft/s)/(32 ft/s²) = t = 3.75 s
The ball will not go any higher after its vertical speed is zero.
Answer:
Step-by-step explanation:
<em>A = 1/4√5(5+2√5)a²</em>

Break apart the 875.
8 becomes 800 the 7 becomes 70 and 5 is just 5. Now x it by the 4
800x4=3200
70x4=. 280
5x4=. 20
-------
3500

Answer:
1. Subtract starting value minus final value.
2.divide that amount by the absolute value of the starting value.
3. Multiplt by 100 to get a percent decrease.
4. if the percentage is negative, it means there was an increase and not an decrease
