The answer to your problem is A because you must add them altogether but i might be wrong im just trying to help you out
We can say that:
8x = -2ax
8 = -2a
a = -4
22y = - 2by
22 = -2b
b = -11
37 = a² + b² - r²
37 = (-4)² + (-11)² - r²
r² = 16 + 121 - 37
r² = 100
r = 10
With all this information, we can say that:
The center of the circle is: (-4 ; -11)
and the radius of the circle is r = 10
P.S:
(a - x)² + (b-y)² = r²
a² - 2ax + x² + b² -2by + y² - r² = 0
x² + y² -2ax - 2by + a² + b² - r² = 0
The answer is 170. First you add base one and base two divide by twi the multiply that by the height. 18+22=40 40/2=20 20•8.5=170
Answer:

Step-by-step explanation:
Rewrite the differential equation as:

Integrate both sides with respect to x:


Integrate one more time both sides with respect to x:


Now that we find the solution, let's find its derivate:

Evaluating the initial conditions:


Replacing the value of the constants that we found in the differential equation solution:
