Answer:
the center is (3,1) and the radius is √6.
Step-by-step explanation:
The center of a circle can be found using the equation 
and is (h,k) from it. Notice h and k are the opposite value as in the equation.
First write the equation in this form.
Complete the square with each variable to find what numbers should go in place of the question marks.
Add 1 and 9 to both sides of the equation.
So the center is (3,1) and the radius is √6.
Given that the roots of the equation x^2-6x+c=0 are 3+8i and 3-8i, the value of c can be obtained as follows;
taking x=3+8i and substituting it in our equation we get:
(3+8i)^2-6(3+8i)+c=0
-55+48i-18-48i+c=0
collecting the like terms we get:
-55-18+48i-48i+c=0
-73+c=0
c=73
the answer is c=73
If you are meaning: 53+3^3 / 30-3
i get 53+9 / 30-3
62/ 27
2.296
Im not 100% on what you were asking but i hope this helps
Answer:
Step-by-step explanation:
sorry im not sure
Use the cross products rule. 6/4 = 21/x. You will get 6x = 84. Divide both sides by 6 to get x = 14 feet.
