Answer:

Step-by-step explanation:

Inside a function, a certain unique input cannot ever have more than one output. All of the other tables have more than one output for only one input.

Answer:

The last one, D it is not a function because the domain (x) does not repeat.

Step-by-step explanation:

To find whether it is a function or not ALL YOU NEED TO DO is check if the domain (x) repeats, it also includes negative numbers like if the domain is

-2, 3, 5, 2 it will be a function because none of these numbers repeat. Yes the number "-2, and 2" repeat BUT one is negative and one is positive, therefore it is a function because they are different numbers when they are negative and positives.

Also just wanted to mention if the (y) repeats it does not matter. It can repeat even a million times, but if the domain numbers (x) do not repeat, therefore it is a function.

Find the area of the circle below???

olga55 [171]

Answer:

Area of the circle = $24.618\,feet^2$

Step-by-step explanation:

Radius of the circle= $2.8\,feet$

Area of the circle= $\pi \times r^2$

As,

$\pi =\dfrac{22}{7} =3.14$

Area of the circle is:

$=3.14\times 2.8 \times 2.8\\\\= 3.14 \times 7.84\\\\=24.618\,feet^2$

The Area of the circle is : $24.618\,feet^2$

BRAINLIEST TO WHOEVER IS CORRECT!!!

Answer:

y= $-\frac{4}{3}$ x+2

Step-by-step explanation:

To write the equation for this line, we are going to use slope-intercept form, which is written as

y=mx+b.

Here are the meanings of each variable:

y= basically the "name" of the function and it always stays as y.

m= slope, which is rise over run.

x= variable that is always on the right of the slope and it always stays as x.

b= y-intercept, or the value that crosses the y-axis.

We will substitute numbers into the equation along the way. The first thing we will want to do is find b, which is the easiest.

The line crosses the y-axis at 2, so that is our value of b.

Our new equation is

y=mx+2.

Next, we will find the slope. The most efficient way of doing this is looking at the lowest point that is already provided, (3, -2), and finding a way to rise and run to the highest point, (0, 2).

If you look closely at the graph, we need to rise up 4 and run over -3 to get to the other point. Therefore, the slope is $-\frac{4}{3}$ , and we can substitute it into our equation, which is completed and is now

y= $-\frac{4}{3}$ x+2

I hope this helps you out!! Have an awesome day ^^
