Answer:
The Musician had $29 before performing at the fairs
Step-by-step explanation:
Let the initial amount musician has be x
At the first musician doubled his money and spent
$30 , this can be written as
2(x) -30---------------------------------(1)
At the second he tripled his money and spent $54.
3(2x -30) - 54
=> 6x-90-54
=> 6x- 144--------------------------------(2)
At the third, he quadrupled his money and spent $72
4( 6x- 144) - 72
24x - 576 - 72
24x -648-------------------------------(3)
At-last he had $48
24x -648 = 48
24x = 48+ -648
24x =696
x = 
x = 29
I believe it’s 72 I hope it’s right

Answer:
0.18 sec or 3.4 sec.
For second part, it will take 3.7 sec.
First part:
Set h(t) = 17and solve for t.
-16t²+ 58t + 7= 17
-16t² + 58t - 10 = 0
Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.
Second part:
Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.
So you must talking about the circumference I guess.
3.14( pi) * diameter.
