The equation of a circle is: (x - h)² + (y - k)² = radius² where (h, k) is the center. Now just plug in your given information and simplify.
(x - 2)² + (y - 0)² = 9²
Your equation is:
(x - 2)² + y² = 81
Answer:
just sub in the numbers into the equation to replace the X ..
example for
a) h(7) : 44
Step-by-step explanation:
h(7) : x^2 -5
sub in 7 into the equation to replace X
so you get
(7)^2 - 5
49-5
44
