the point (8,5) lies on a circle and the center of the circle is at the point (7,5).

what is the equation of this circle?

a. (x - 7)2 + (y - 5)2 = 1

b. (x - 5)2 + (y - 7)2 = 1

c. (x - 7)2 - (y - 5)2 = 1

d. (x - 5)2 - (y - 7)2 = 1

the answeer is a.

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?
