Answer:
Step-by-step explanation:
The vertex will occur when t=-b/(2a) for the quadratic ax^2+bx+c
In this case
t=-200/(2(-16))
t=-200/-32
t=6.25
g(6.25)=-16(6.25^2)+200(6.25)
g(6.25)=625ft
So the maximum height of the rocket is 625 feet and it reaches this height at 6.25 seconds.
A)Total hours she worked =8+7.5+6.5+3+9= 34 hours
b)Amount she was paid= 34 hours x $20.25= 688.50
She was paid $688.50

Answer:
(b) √55
Step-by-step explanation:
The right triangles in this geometry are all similar, so the ratio of long side to short side is the same:
y/5 = 11/y
y² = 55 . . . . . . multiply by 5y
y = √55 . . . . . take the square root
__
And x=4√5 by looking at ratios of short side to hypotenuse.
Answer:
volume = 684π m³ or 2148.85 m³
Step-by-step explanation:
volume = (π6² x 11) + (4/3π6³) = 396π + 288π = 684π m³ or 2148.85 m³
