C is a function. You can tell easily by doing the vertical line test. Put your finger pen pencil, etc. up to the graph vertically and see if at any point it touches more than one point at once. If it doesn't, it's a function.

Help me pls I don’t know how to do this I’ll give brainliest pls help
Natalka [10]

Answer:

3/2

Step-by-step explanation:

First, you find the mean (((4 + 5 + 6 + 1)/4) = 4)

Find the absolute difference between each data value and the mean: 0, 1, 2, 3

Add the differences (in the previous step) and divide by number of terms: (0+1+2+3)/4 = 6/4 = 3/2

Someone please help and explain it would really help
Vaselesa [24]

So when you're solving for x here and distribute 8 on the right side, it would look like this:

8x+47=8(x+5)\\ \\ 8x+47=8x+40

Now in order to solve for x, we know we have to get all the x's on one side of the equal sign. Let's get all our x's to the left side. Since the right side has a positive 8x, you need to subtract 8x on the right. But whatever you do to one side you must do to the other. So since we are subtracting 8x on the right, we need to do that on the left.

But we can't! Since both sides will cancel out to zero before x can be solved.

Therefore the answer is 0.

Hope that helps!

Find the average of these numbers. 23, 24, 27, 25, 26, 23, 21, 32, 29, 30
Pavel [41]

Answer:

26

Step-by-step explanation:

First, add all the numbers together

23 + 24 + 27 + 25 + 26 + 23 + 21+ 32 + 29 + 30= 260

Then divide by the number of terms there are, in this case 10

260/10= 26

Oakville is a fungal disease that infects oak trees scientists have discovered that a single tree in a small forest is infected
Galina-37 [17]

Answer:

I solved part a

To solve this question, we need to solve an exponential equation, which we do applying the natural logarithm to both sides of the equation, getting that it will take 7.6 years for for 21 of the trees to become infected.

PART C

The logarithmic model is: g(x)= in x/0.4

We are given an exponential function, for the amount of infected trees f(x) after x years.To find the amount years needed for the number of infected trees to reach x, we find the inverse function, applying the natural logarithm.

Step-by-step explanation:
