For this case we can do this:

Since Marnie has bought her car,the value has gone down 15%.If her car is 13000 right now,how much was it worth when she bought
Serggg [28]
Percentage of depreciation of the car that Marie bought = 15%
Present value of the car = 13000
Let us assume that the value of the car at the time of buying = x
So
The percentage valuation of the car now = (100 - 15) percent
                                                                 = 85 percent
Then
(85/100) * x = 13000
85x = 13000 * 100
85x = 1300000
x = 1300000/85
  = 15294.12
So the actual cost of the car is 15294.12. I hope the procedure is clear enough for you to understand.

Answer:

the period of this graph is 2\pi

Step-by-step explanation:

The period is the length of the section that repeats.  So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.

Let's look at the peaks (maximums).

One is at x = 0 and the next is at x = 2\pi

2\pi - 0 = 2\pi

Therefore, the period of this graph is 2\pi
