The number of items is modeled by h(x) = 0.42x^2 + 0.3x + 4, and the cost per item is modeled by r(x) = −0.005x^2 − 0.2x + 7. The total cost is the product of the number of items and the cost per item. Identify a polynomial q(x) that can be used to model the total cost.

answer: it is d

step-by-step explanation:

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
