Suppose the circumference of a circle is 15pi. What is its diameter?

1 answer:

7 0

The circumference of a circle is proportional to its diameter.

$C\propto d\\ \\ \therefore \quad C=kd$

Now, when d=1, C=π, therefore:

k=π

This means that:

$C=\pi d$

If C=15π:

15π=πd

Therefore:

d=15

A rectangle has length 7 inches and width 3 inches.

Naya [18.7K]

Answer:

The area of rectangle is 21 in^2

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

where

L is the length

W is the width

In this problem we have

$L=7\ in$

$W=3\ in$

substitute

$A=(7)(3)=21\ in^2$

The draw in the attached figure

therefore

The area of rectangle is 21 in^2

What value of k will make this relationship NOT a function?

devlian [24]

Answer:

the correct answer is b.

Step-by-step explanation:

it is b because if you plug in -7, two of the x-values will have -7 making the x-values the same and in order to be a function all x-values have to be different.
