Answer:
The center is (-3,2) and the radius is r=2
Step-by-step explanation:
The general equation of the given circle is
Add the square of half the coefficient of the linear terms to both sides of the equation to obtain;
The quadratic trinomials in x and y on the left side of the equations are perfect squares.
We factor to obtain;
Comparing to:
The center is (-3,2) and the radius is r=2
Answer:
BA=BC
Step-by-step explanation:
The area of the given composite figure is 34 square feet
<h3>Area of rectangle</h3>
Area of the rectangle = length * width
<h3>Get the area of the given composite figure</h3>
For the composite figure shown:
Area = (8*3) + (2 * 5)
Area = 24 + 10
Area = 34 square feet
Hence the area of the given composite figure is 34 square feet

Answer:
The median dr smith is 15
Step-by-step explanation:
Repari cost (x) = y = 35.25 x + 40
x = number of hours to repair the car.
Every hour the cost will increase 35.25, becasue 40 is a fixed cost.
if x = 1, repair cost(1) = 35.25 + 40
if x = 2, repair cost (2) = 35.25*2 + 40
if you subtract repair cost (1) from repair cost (2) you get 35.25*2 - 35.25 = 35.25
The same thing every time the repair time increases one hour.
Answer: the last option of the list, for every hour of labor, the cost increases by $35.25
