Answer:
Step-by-step explanation:
The position equation is given as
and we are looking for the times when the position of the ball is 9 feet. That means that we simply plug in a 9 for s(t) and factor to solve for t:
and
and this is what we factor to find t:
t = .42 sec and then again on its way back down at t = .89 sec
The answer is r = ∛(T²GM/4π²)
T² = (4π²/GM)r³
Divide both sides by 4π²/GM
T²/(4π²/GM) = (4π²/GM)r³/(4π²/GM)
T² * GM/4π² = r³
r = ∛(T²GM/4π²)

Answer:
4
Step-by-step explanation:
The question is find the total cost when the price is $89.75 and the tax is 7 1/4%
Total cost = price + tax
Tax = 7 1/4 % of price
Tax rate = [7 + 1/4] = 7.25 %
Tax = 7.25 % * price = 7.25 % * $89.75 = $[7.25/100] * 89.75 = $6.51
Total cost = $89.75 + $ 6.51 = $96.26
