write an equation for the cubic polynomial p(x) with leading coefficient of -3 a linear coefficient of 2 , p(0)=9 p(3)=6.

Step-by-step explanation:

let p(x)=ax³+bx²+cx+d

a=-3

c=2

p(0)=9

d=9

p(3)=-3(3)³+b(3)²+2(3)+9=6

-81+9b+6+9=6

9b=6+81-6-9

9b=72

b=72/9=8

so p(x)=-3x³+8x²+2x+9

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
