Answer:

81/5 or 16 1/5.

Step-by-step explanation:

First convert the mixed number to an improper fraction:

3 6/7

= (3*7 + 6) / 7

= 27/7.

So we have

27/7 / 5/21

Invert the second fraction and multiply:

= 27/7 * 21/5

= (27*21) / (7*5)

= (27*3) / 5 ( as 21/7 = 3)

= 81/5

= 16 1/5.

Find f(3) given that f(3) = -x^4 + 3x^3 + x^2 - 8x - 16.

Hitman42 [59]

Answer: -31

<u>Step-by-step explanation:</u>

f(x) = -x⁴ + 3x³ + x² - 8x - 16

f(3) = -(3)⁴ + 3(3)³ + (3)² - 8(3) - 16

= -81 + 81 + 9 - 24 - 16

= -31
