For y = 4x + 2x2 – x3, show how to find the value for y, when x = 2. Show your work
1 answer:
To find the value of y in the given equation, substitute the given value of x to the equation.
y = 4x + 2x² -x³
Substitute 2 for all x's.
y = 4(2) + 2(2²) - 2³ = 8
Therefore, the value of y is 8.

Answer:
168pi cm2
Explanation:
SA = 2pi(r^2) + 2pi(r)h
diameter is 8 cm so radius is 4 cm
SA = 2pi(4^2) + 2pi(4)17
SA = 32pi + 136pi
SA = 168pi cm2
