Answer:

C - The relationship represents a function because each input gives one unique output.

Step-by-step explanation:

To see if it is a function we can do the line test where we have a vertical line and "drag" it along the line. As long as it only hits the line once in every situation it is a function! We can see this passes and therefore the answer is c.

(why is it not d? you can have a non-linear line, but still have a function)

Answer:

<h3> $\boxed{ \bold{ \huge{ \boxed{ \sf{ {12.56 \: {mm}^{2} }}}}}}$ </h3>

Step-by-step explanation:

Given,

Radius ( r ) = 2 mm

pi ( π ) = 3.14

Finding the area of circle having radius of 2 mm

Area of circle $\sf{ = \pi \: {r}^{2} }$

plug the values

⇒ $\sf{3.14 \times {2}^{2} }$

Evaluate the power

⇒ $\sf{3.14 \times 4}$

Multiply the numbers

⇒ $\sf{12.56 \: {mm}^{2} }$

Hope I helped!

Best regards!!

What is the range of possible sizes for side x?

inessss [21]

Answer:

1.3 > x > 6.7

Step-by-step explanation:

The sizes would be 4.0 - 2.7 and 4.0 + 2.7, so 1.3 and 6.7, so

1.3 > x > 6.7

12 -1/9d = 17

Subtract 12 from both sides

-1/9d = 5

Multiply both sides by -9:

D = -45

The answer is b. d = -45

Hello there! How are you today?

The answer choices appear to be indicating that we must apply the distributive property to find our simplified expression. To apply the distributive property, we must multiply the number outside of the parenthesis by all numbers inside of the parenthesis.

For example;

2(1 + 3)
Multiply 2 by all numbers inside of the parenthesis separately.

2(1) + 2(3)
2 + 6
8.

Now that we've explained and (hopefully) understand the concept of our problem, let's prepare to solve.

We have the following expression and answer choices:
96 + 36

A.) 4(24 + 9)
B.) 6(16 + 6)
C.) 12(8 + 3)
D.) 18(5 + 2)

Before we proceed to solve for this, let's evaluate our question carefully.

"Tonya uses the greatest common factor and the distributive property to rewrite this sum: 96 + 36"

Now, let's list the factors out from each number.

96;

1 x 96
2 x 48
3 x 32
4 x 24
6 x 16
8 x 12

36;

1 x 36
2 x 18
3 x 12
4 x 9
6 x 6

Now that we've listed our factors, let's take a look and see which answer choices contain our factors and which don't.

A, B, and C all list factors that are shown above. However, D doesn't as it has "5", which we do not have any numbers that end in 5 or 0, so we can remove answer choice "D" off of our list.

We are now remaining with answer choices A, B, and C.

Since the question requests that we use the greatest common factor, let's take a look into our factors and see which one is the greatest.

The greatest common factor is "12", so we should look for the answer choice that best matches 12.

Answer choice "C" is the only answer choice that contains our greatest common factor, 12.

Your answer is "C.)"

I hope this helps!

Determine whether these two functions are inverses.

11Alexandr11 [23.1K]

Answer:

No The reactions are not inverses to each other

Step-by-step explanation:

f(x) = 3x + 27

Let f(x) be y

y= 3x+27

subtracting 27 on both sides

3x = y - 27

x= (y-27)/3

= y/3 - 9

inverse function is x/3 -9 not x/3 + 9

Therefore, not an inverse

Hope it helps...
