Answer:
B. (6,-2)
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
The center of the circle is (h,k)
So, in this problem, h is 6 and k is -2, so the center of this circle is (6,-2).
Answer:
11.0
Step-by-step explanation:
Using Pythagoras' identity in the lower right triangle.
let the hypotenuse be x , then
x² = 4² + 9² = 16 + 81 = 97
Within the rectangle, use Pythagoras' identity in the lower right triangle.
let y be the dotted line , then
y² = x² + 5² = 97 + 25 = 122 ( take the square root of both sides )
y =
≈ 11.0 ( to the nearest tenth )
The dotted line is approximately 11.0 units
Answer:
It's cheaper to eat out.
Step-by-step explanation:
I suppose you want to solve the following equation for b:

First of all, you need to divide both sides by 9:

Then, subtract 2 from both sides:
