Atype of fabric costs $2.48 per yard. in a relation, the input is the number of yards of the fabric and the output is the cost.

Option A

Step-by-step explanation:

A relation can be defined as a function if there is only one output for each input.

In this case, the output is the cost of the fabric and the input is the number of yards of fabric.

Then, for each number of yards of fabric there will be a cost. But there will not be two different costs (outputs) for the same number of fabric yards (entrance)

Then the answer is the Option A: Yes, because one imput (number of yards of fabric) will always have the same output (costs)

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
