Answer:
0.0
Step-by-step explanation:
Used a calculator
Replace F(x) with y
y=x^3-10x^2+24x
To find the roots replace y with 0.
0=x^3-10x^2-24x
Rewrite the equation as
x^3-10x^2+24x=0
Factor the left side
x(x-6)(x-4)=0
The solution is a result of
x=0, x-6=0, and x-4=0
The answer is:
x=0, 6, 4
B) 43 because they increase 3
c) 32 because they decrease 7
To find the rate, we have to divide both numbers by 5. So the rate will be $1.592 for 1 pound.
