Answer:

As the wheel makes this 270 degree counterclockwise rotation about the origin, the y-coordinate of the first car decreases from 80 to 0 and then further from 0 to -80, and finally increases to 0.

The x-coordinate decreases from 0 to -80 and then increases to 0; from there it increases further to 80.

Thus, the coordinates of the first car, after this 270-degree rotation, are (80, 0).

I don't really understand these because our teachers expect me to know this when she didn't teach us this.
stealth61 [152]
First, find the percentage of the price after the sale occures
percent = 100% - 20%
percent = 80%

We need to find the price for the pairs with the percentage above
new price = percentage of new price/percentage of old price × old price
new price = 80%/100% × 55
new price = 4/5 × 55
new price = 44
The new price is $44

Now we estimate how much the tax
tax = 6% × 44
tax = 6/100 × 44
tax = 2.64

Calculate how much Josie will pay
pay = new price + tax
pay = 44 + 2.64
pay = 46.64

Josie will pay $46.64
