7 John is painting a sign of a rising sun, which happens to be exactly half of a circle. The half-
circle's base is 30 inches long. He'll need to buy enough paint to cover how much space?
(Approximate pi to 3.14)

A = { bor?
900 sq. in.
1,413.00 sq. in.
353.25 sq. in.
30.00 sq. in.

353 square inches

Step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
