Answer:
x^2+y^2=9^2
Step-by-step explanation:
The standard equation of a circle is:
Where the center of a circle is (h,k) and r is the radius of the circle. In this case because a circle is equidistant from the center and we have a point where it passes through 9 that means that the radius is 9. However, since the standard equation states that we must write r in the form of 
this means that 
. Therefore by plugging in the values we have:
The answer is 3. -1/2 n + 1 1/2 n add the coefficients to get 1n or just n. then n-n is 0 what is left is 3.
Answer:
(x+3)(x-4)^2
Step-by-step explanation:
= (x+3)(x^3-5x^2-8x+48)/(x+3)
= x (x^3-5x^2-8x+48)/(x+3)
= x^2-8x+16
= (x+3)(x-4)(x-4)
= (x+3)(x-4)^2
Answer:
I think -10 is the answer
Answer:
3.45
Step-by-step explanation:
15 percent of 23
15 percent to decimal = 0.15
23 x 0.15 = 3.45
