Answer:

D (last one), x^2+y^2=45

Step-by-step explanation:

We need to find the distance between (0,0) and (-3,6). Using the distance formula we get:

d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

d=\sqrt{\left(-3-0\right)^2+\left(6-0\right)^2}

d=3\sqrt{5}

Since equation of circle is: x^2+y^2=r^2 we have to square the distance we just found, which gives us 45.

A car dealership increased the price of a certain car by 13%. The original price was $47400 what is the new price?
garik1379 [7]

Answer:

Step-by-step explanation:

To get the new price of the car multiply the original price by the percent increase in decimal form  +1. 11% in decimal form is 0.11 = 11/100. Add one to this and you get 1.11 = 1 + 0.11. So now multiply $49,800 * 1.11 = $55,278. If the problem had said they decreased the price by 11% you would use 1 - 0.11 = 0.89 because 89% is 11% less than 100%.

hope that helps my man
