Nate works at least 4 hours but not more than 9 hours. he earns $12.40 per hour. the function f(t) = 12.4t represents the amount of money he earns for working t hours. choose the practical domain and the practical range for this situation. there are exactly 2 correct answers. (hint: the answers need to make sense for the situation! ) question 10 options: the practical domain is all real numbers from 4 to 9, inclusive. the practical domain is all real numbers. the practical range is all real numbers from 49.6 to 111.6, inclusive. the practical range is all real numbers from 4 to 9, inclusive.

The practical domain is all real numbers from 4 to 9, inclusive.

The practical range is all real numbers from 49.6 to 111.6, inclusive.

These are the correct options.

Explanation:

Given function is f(t) = 12.4t

Let us assume that Nate works 'x' hours so 4<x<9

And multiplying the hours with his earnings we get the range.

4*12.40=49.6 and 9*12.40=111.6. Let the amount earned be represented by y

Hence, domain can be represented as 4<x<9 and range can be represented as  49.6 < y < 111.6

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
