Answer:
The correct answer is the first one listed.
Step-by-step explanation:
First you have to determine what the equation for that circle is. The standard form of a circle is
where h and k are the coordinates of the center and the radius is squared. Using the given info, our equation will look like this:
Now we use the coordinates given and plug in 2 for x and 3 for y and do the math and see if the 2 sides are equal.
and 9 + 16 = 25, right? So that's how you can check the other coordinate pairs to verify that they DON'T work out!
X = 10
the two sides are congruent and you know that by finding the other angle 90+45= 135
180-135=45
y= 14.1
10^2+10^2=c^2
100+100=c^2
200=c^2
14.142.. =c
Divide total money collected by amount charged per car to find number of cars washed.
=$291 total ÷ $3 a car
=97 cars
ANSWER: They washed 97 cars.
Hope this helps! :)
Just multiply 3 and 16 and that gives you 48 days.
