Which of the following circles lie completely within the fourth quadrant?
check all that apply.

a. (x - 2)2 + (y + 7)2 = 64
b. (x - 12)2 + (y + 0)2 = 72
c. (x - 9)2 + (y + 9)2 = 16
d. (x - 5)2 + (y + 5)2 = 9

The best and most correct answers among the choices provided by the question are  the following :
C. ( x  -  9) 2 + ( y + 9 ) 2 = 16
D. ( x  -  5) 2 + ( y + 5 ) 2 = 9

Hello!

the answer is:

the answer is:

why?

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

Ibelieve it's a. 2.2 - x = -10.85 (plz tell me if it's right : ) )
