5) Is 3 a zero (or root) of f(x) = x3 - 9x2 + 11x + 21?

frozen [14]

Answer:

Yes

Step-by-step explanation:

f(x) = x³ − 9x² + 11x + 21

f(3) = (3)³ − 9(3)² + 11(3) + 21

f(3) = 27 − 81 + 33 + 21

f(3) = 0

Which rate is the lowest price? <br> $6.30 for 9 <br> $5.50 for 5 <br> $4.20 for 7 <br> $0.80 each

Sedbober [7]

Answer: $4.20 for 7
This problem can be solved by dividing the pay by the number of items.

$6.30 / 9 = $0.70
$5.50 / 5 = $1.10
$4.20 / 7 = $0.60
$0.80 / 1 = $0.80

This shows that for the third option, $4.20 for 7, the rate per item is the lowest.
