Answer:
f(2) = -2
Step-by-step explanation:
Substitute 2 everywhere you see an x so f(2) = -2(
) - 2(2) + 10 so
f(2) = -2(4) - 4 + 10, so f(2) = -8-4+10, f(2) = -12+10, f(2) = -2
V=pir^2(h/3)
V= 3.14x18^2x6/3
V= about <span>2034.72</span>
Equation: C=dπ
C=6·3.14
C=18.84
answer^^^
(15 qt/hr) x (1/4 gal/qt) x (1/60 hr/min) =
(15) / (4 x 60) = 0.0625 gal/min
