Answer:
See below
Step-by-step explanation:
Vertical velocity will be affected by gravity in this scenario
df = do + vo t + 1/2 a t^2 do = original height = 4 ft a = -32.2 ft/s^2
<u>df = 4 + 89 t - 1/2 (32.2) t^2 df = height</u>
<u />
On the way up and the way down, the ball may reach height of 102.2125 ft :
102.2125 = 4 + 89 t - 1/2 (32.2) t2 re-arrange to:
-16.1 t^2 + 89t - 98.2125 =0
Use Quadratic Formula to find <u>t = 1.5 and 4.0 s </u>
There are no numbers for this, thus you will have to use the quadratic formula.
1) May: 248$ and june 265$. The difference is 17$ and then you divide the difference with the old price: 17/ 248 = 6,85%
2) Same method, the difference is 59$ so 27,44%'
3) The difference is 9,5$ so you answer is 63,3%
<span>4) The difference is 10$ divided by the original price: 10/24 = 41,66%</span>
2 hours of computer time divide by 10 students:
2/10 = 1/5
