Answer:
Part 1) Option A. h(2) = 86.00 means that after 2 seconds, the height of the ball is 86.00 ft
Step-by-step explanation:
we have
![h(t)=-16t^{2}+150](https://tex.z-dn.net/?f=h%28t%29%3D-16t%5E%7B2%7D%2B150)
where
t ----> is the time in seconds after the ball is dropped
h(t) ----> he height in feet of a ball dropped from a 150 ft
Find h(2)
That means ----> Is the height of the ball 2 seconds after the ball is dropped
Substitute the value of t=2 sec in the equation
![h(2)=-16(2)^{2}+150=86\ ft](https://tex.z-dn.net/?f=h%282%29%3D-16%282%29%5E%7B2%7D%2B150%3D86%5C%20ft)
therefore
After 2 seconds, the height of the ball is 86.00 ft.
Rob scored 34 points. 88-54=34
To find the time in which all the bells ring together, we need to find the LCM of 36,40,48.
Prime factorization of 36=2×2×3×3
Prime factorization of 40=2×2×2×5
Prime factorization of 48=2×2×2×2×3
Hence, LCM of 36,40,48=2×2×2×2×3×3×5=720 seconds.
720seconds=
60
720
minutes=12minutes
Hence, all the bells will ring together after 12 mi
