Answer: 51

Step-by-step explanation: A prime number is a number that is greater than 1 and it has two factors which are 1 and itself.

23 is a prime number because it has no other factors besides 1 and 23. In other words, there is no other number multiplied by a number than will equal 23 so we call it a prime number.

The center of a circle is at (-5 12) and it has a radius of 16. what is the equation of the circle?

Naya [18.7K]

Answer:

(x+5)^2+(y-12)^2=256

Step-by-step explanation:

Comparing the given (x+5)^2+(y-12)^2=256

to (x - h)^2 + (y - k)^2 = r^2,

we see that h must be -5, k must be 12 and r must be 16. This is the desired equation of the circle with center at (-5, 12) and radius 16.
