Attached solution with detailed work using compound interest formula.
Answer:

Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Slope: 
Point: (3, 2) = (x1, y1)
To write the equation in point-slope form, we need to know the values of the slope and one point. Since we've already been given those values, all we have to do is input them into the equation:
y - y1 = m(x - x1)

The equation in point-slope form is: 
Answer:
it's potential energy decreases
5 is not a function because if you draw a vertical line then it touches twice which is not a function
6 is a function
7 is not a function because there are 2 of the same inputs
8 is a function because it passes the vertical line test
9 is not a function
10 is a function
Hopefully that helped!
Answer:
4
Step-by-step explanation:
since the fraction is 1/4 you can multiply 4 by 4 and get sixteen and 4x1=4
