The answer to this is the top left answer choice.
Answer:
B
Step-by-step explanation:
hope this can help you very much
The roots of a polynomial are the values that render the polynomial to zero
y=(x+4)(x-2)^2(x+7)
in the 1st parenthesis, x=-4 render the polynomial =0
in the 2nd parenthesis, x=2 render the polynomial =0
in the 3rd parenthesis, x=-7 render the polynomial =0
So there are 3 values as roots of this polynomial (answer C)
218
If you take 11-9=2
20-11=9
29-20=9
227-218=9
F(x) = 3.55x - 4...17 customers....17 = x
f(17) = 3.55(17) - 4 =
f(17) = 60.35 - 4 =
f(17) = 56.35
f(x) = 3.55x - 4...21 customers....21 = x
f(21) = 3.55(21) - 4 =
f(21) = 74.55 - 4 =
f(21) = 70.55
ok...I think u can see how I am doing this...answer should be easy to find..lol
