1/10 of .9 is the same as dividing .9 by 10.
.90 / 10 = .09
.09 is the answer
Answer:

Step-by-step explanation:
we know that
The roots of the polynomial are the values of x when the value of the polynomial f(x) is equal to zero
The roots of the polynomial function are
x=-6 -----> (x+6)=0
x=-5 -----> (x+5)=0
x=-1 -----> (x+1)=0
The equation of the cubic polynomial is

where
a is the leading coefficient
Remember that
f(0)=60
That means ------> For x=0 the value of f(x) is equal to 60
substitute the value of x and the value of y in the function and solve for a




so

Applying the distributive property
Convert to expanded form

I think it would be $14 per book
14.08 that’s if in this case “of” means multiply hope this helps
