The answer is (f . g)(x) = - (34k + 17k⁷ + 17k⁵ + 40k³ + 20k² + 60).
Remember that :
<u>(f . g)(x) = f(x) × g(x)</u>
<u />
Hence :
- (f . g)(x) = (2k³ + k² + 3)(-17k⁵ - 20)
- (f . g)(x) = -34k⁸ - 17k⁷ - 17k⁵ - 40k³ - 20k² - 60
- (f . g)(x) = - (34k + 17k⁷ + 17k⁵ + 40k³ + 20k² + 60)
diameter is radius x 2
3.5 x 2 = 7 inches
Area = PI x r^2
using 3.14 for PI
area = 3.14 x 3.5^2 = 3.14 x 12.25 = 38.465 square inches round answer as needed
N•2>8
then dive both sides 2n>8
and get n>4
