Question

Select the correct answer. Which point lies on the circle represented by the equation x2 + (y − 12)2 = 252? A. (20,-3) B. (-7,24) C. (0,13) D. (-25,-13) Reset Next

Answer 1

A.

Explanation:

the only thing we can do is try the various (x, y) pairs in the equation, and see, for which pair the equation is true.

first, write the equation properly ;

x² + (y - 12)² = 252

A. (20, -3)

20² + (-3 - 12)² = 252

400 + 225 = 252

625 = 252 wrong

B. (-7, 24)

(-7)² + (24 - 12)² = 252

49 + 144 = 252

193 = 252 wrong

C. (0, 13)

0² + (13 - 12)² = 252

1 = 252 wrong

D. (-25, -13)

(-25)² + (-13 - 12)² = 252

625 + 625 = 252

1250 = 252 wrong

so, none of the answers seems to be right.

could it be that you meant

x² + (y - 12)² = 25² = 625

because then A. is

20² + (-3 - 12)² = 625

400 + 225 = 625

625 = 625 true

so, you see how important the correct writing is ?
