Answer:
f(x) = - 4x² + 24x - 20
Step-by-step explanation:
Given
f(x) = - 4(x - 3)² + 16 ← expand the factor using FOIL
= - 4(x² - 6x + 9) + 16 ← distribute parenthesis by - 4
= - 4x² + 24x - 36 + 16 ← collect like terms
= - 4x² + 24x - 20
Answer:
60π in²
Step-by-step explanation:
Lateral surface area for a circular cone is given by the formula in the attached picture.
Lateral Surface Area,
=πr √( r² + h²)
=π (6) √( 6² + 8²)
= π6 √( 36 + 64)
= 6π √(100)
= 6π (10)
= 60π in²
Answer:
60 pi sq. in.

Hope it helps.
tis noteworthy that 7 months is not even a year, since there are 12 months in a year then 7 months is really 7/12 of a year.
