Today 108 people visit at a waterpark during the first hour that the park was open this number of people is 40% of the total number of people who visited the water park during the first hour yesterday how many people visit the water park during the first hour yesterday

180 people

Step-by-step explanation:

100% - 40% = 60%

60/100 = 0.6

108 ÷ 0.6 = 180

the answer is 15% decrease

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!
