Answer:
The equation of the circle is (x -8)² + (y -4)² = 184.96
Step-by-step explanation:
In order to determine the equation of this circle we first need to calculate the coordinates of the center, which are given by the difference of the coordinates divided by two. We have:
Xc = [13 - (-3)]/2 = (13 + 3)/2 = 16/2 = 8
Yc = (11 - 3)/2 = 8/2 = 4
Therefore the center is (8,4). We now need to find the radius of the circle, which is given by the distance from the center to one of the points given:
r = sqrt{[8 - (-3)]² + (11 - 3)²} = sqrt(11² + 8²) = 13.60
The equation of a circle is given by:
(x - Xc)² + (y - Yc)² = r²
(x -8)² + (y -4)² = (13.6)²
(x -8)² + (y -4)² = 184.96

Hello,
Step-by-step explanation:
Answer:300
Step-by-step explanation:25 cents each quarter so the equation would be 12 times 25.
Answer: look at the pictures
Step-by-step explanation:
Here, Your Expression: y = 0.25 (2^x)
So, we can see the expression is "Exponential" which increases double in every hour. So, the only graph with that pattern is 3rd one.You can compare following coordinates: (1, 50), (2, 100), (3, 200)
For every 1 value of x, y increases to it's double.
In short, Your Answer would be Option C
Hope this helps!
