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
Answer:
2.6

Step-by-step explanation:
Answer:
49°
Step-by-step explanation:
Since the angle measures of QPR and RPS add up to 88 degrees, you can set up an equation to solve for x and then RPS.
5x+34+8x+15=88
13x+49=88
13x=39
x=3
RPS=5x+34=5(3)+34=15+34=49°
Hope this helps!
