Kevin is the ceo of sunrise medical inc., a wheelchair manufacturer working with eskenazi hospital. when kevin charges $100 per wheelchair the average annual eskenazi order is 2000 wheelchairs. for every $30 increase in the wheelchair price, eskenazi's order decreases by 125. y = revenue x = number of $30 increases write 1(one) expression for one of the factors whose product is the revenue. write a second expression for one of the two factors whose product is the revenue. which expression best represents the simplified revenue quadratic equation? y = x^2 + 475x + 2000 y = - x^2 + 475x + 2000 y = 3750x^2 + 47500x +200000 y = - 3750x^2 + 47500x +200000 y = 37500x^2 + 475000x +2000000 y = - 37500x^2 + 475000x +2000000 what is the maximum price kevin can charge for a wheelchair before losing revenue?

i can you, i love poetry

whatare you sayig

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!
