Melissa bought a cake that cost $75. the sales-tax rate is 10 percent. what is the total amount she paid for the cake?

the total amount she paid for the cake, $82.5

Step-by-step explanation:

As per the statement:

Melissa bought a cake that cost $75.

⇒Cost of cake = $75

It is also given that:

The sales-tax rate is 10 percent.

then

Sale tax she gave on cake =

We have to find the total amount she paid for the cake.

Substitute the given values we have;

therefore, the total amount she paid for the cake, $82.5

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.
