Answer:
Third choice
Step-by-step explanation:
The standard form of a circle is
where h and k are coordinates of the center and r is the radius squared. We have h = 2, k = 7, and r = 4 (we will have to square it to fit it into the equation properly). Filling in accordingly:
The third choice is the one you want.
[(9 + 7i)/(-10 + 8i)] * [(-10-8i)/(-10-8i)]
[(9+7i)(-10-8i)] / [(-10+8i)(-10-8i)]
[(9+7i)(-10-8i)] / (100 + 64)
Can you go from here?
The value of the digit 9 is 900,000 or nine hundred thousand.
Hope this helps :)
You can use slope formula to find slope of given points.
m = (y2-y1)/(x2-x1)
m = (-6-11)/(-3-5)
m = -17 / -8
Cancel out minus sign in both nominator and denominator. Thus,
m = 17/8
Hence, the slope is 17/8
