The equation of any given circle is:

where (h, k) is the center and r is the radius.
In the problem, we are given the center, and the radius. When we plug them in:

we got the formula of the circle.
 
        
             
        
        
        
15% of 25 is the greatest of the two.
Answer:
25% of 15 is 3.75 
15% of 25 is also 3.75 
15 - 3.75 = 11.25 
25 - 3.75 =21.25
Compare and then determine. 
11.25 < 21.25

Answer:
Ann us correct. It's a quadratic function.
Step-by-step explanation:
Given equation is,
y = 3x(x - 7)
By converting this equation into the standard quadratic equation,
y = 3x² - 21x
Highest exponent of the polynomial equation is 2 (Exponent of highest degree variable x²). This decides that the given function is a quadratic function.
Therefore, Ann is correct. It's a quadratic function.
