Answer:
It is the second graph, the one with two filled in dots, but no line.
Step-by-step explanation:
The reason it is not the first one is because it has not filled in dots, AND no line, so it's basically saying there is no answer, which is not true.
The reason the third one (the one with a line) is wrong is because, for example, x cannot be 1, because 1 ≠ 2, and if there is a line, it should be true.
Answer:
C is the correct answer
Step-by-step explanation:
the amplitude is multiplied by the power and the magnitude is raised to that power
<u>C. 42 units</u>
Step-by-step explanation:
I have attached a diagram to help you understand this problem. By looking at the diagram you can see that AE is half of BD, and that BD will be equal to AC. So we need to figure out the length of line BD to get AC.
To do this, you will multiply the length of AE by 2 and set it equal to BD.

Then distribute, multiply what is in the parentheses by 2.

Subtract 4x from both sides.

Subtract 2 from both sides.

x = 8
Now that we have x, we can plug it into the equation to find BD.

BD is equal to 42 units, so we know...
<u><em>AC = 42 units</em></u>
