If x^2 + y^2 = 50, then the greatest possible value of y is between Choose the correct choice from the following choices.
A) 2 and 3 B) 4 and 5 C) 5 and 6 D) 7 and 8 E) 9 and 10
for the greatest possible value of y^2, we must minimize the value of x^2 i.e. lets say x^2 = 0   then we need to find a number y such that y^2 &lt; 50. 7^2 = 49 and 8^2 = 64 so we can say that the maximum possible value of y can be a little more than 7 hence answer = between 7 and 8   hence 7 and 8
