Answer:
h² + 9h + 23
Step-by-step explanation:
Given
f(x) = x² + 3x + 5
To evaluate f(3 + h) substitute x = 3 + h into f(x), that is
f(3 + h) = (3 + h)² + 3(3 + h) + 5 ← expand (3 + h)² using FOIL
= 9 + 6h + h² + 9 + 3h + 5 ← collect like terms
= h² + 9h + 23
Answer:
<h3>
The cylinder's radius is <u> 2 </u> inches </h3><h3>
and it’s height is <u> 3 </u> inches.</h3>
Step-by-step explanation:
A diameter is two radiuses long, so the cylinder's radius is:
R = 4 in ÷ 2 = 2 in
The volume of cylinder is: V = πR²×H
Therefore:
12π = π×2²×H
12 = 4H
H = 3 in
