Answer:
option C
Step-by-step explanation:
f(x)=-0.08x(x^2-11x+18)
Factor the parenthesis and find out the x intercepts
(x^2-11x+18)
We find out two factors whose product is 18 and sum is -11
-9 and -2 gives us product 18
-9 -2 gives us sum -11
(x^2-11x+18) =(x-9)(x-2)
f(x)=-0.08x(x^2-11x+18)
f(x)= -0.08x(x-9)(x-2)
set f(x) =0 and solve for x
-0.08x(x-9)(x-2) =0
-0.08x =0, so x=0
x-9 = 0 , so x=9
x-2 =0 , so x=2
x intercepts are (0,0) (2,0) and (9,0)
x intercepts are not repeating
so the graph crosses x -axis at x=0, 2,9
option C is correct
The graph is attached below4
The answer is 2 1/5 because 1 3/8 is =11/8 TIMES 2/5 IS 2 1/5
hope it helped.
Answer:
A B and E
Step-by-step explanation:
Mate, stop repeating questions, wait until your question has been answered.
15% of 180 is (180 * 0.15) = 27.
180 - 27 = $153 paid.
20% of 200 = (200 * 0.2) = 40.
200 - 40 = $160 paid.
Therefore Sport City offered the better deal.
