Answer:
Step-by-step explanation:
Volume = πr²h/3 = πr²9/3 = 3πr²
3πr² = 3πy² + 30πy + 75π
r² = y² + 10y + 25
r² = (y+5)²
r = y+5
The simplified form of the expression is -11/9
<h3>Rational expressions</h3>

Answer:
x=0
x=10
x=24
Step-by-step explanation:
f(x) = -.05x^2 + x +6
The initial value is 6 ( Let x=0 and f(0) = 6)
f(x) = -.05( x^2 -20 x -120)
I plotted the equation and maximum is at x=10 and the zero is at x=25
Step-by-step explanation:
