Does the point (10,3) lie on the circle that passes through the point (2,9) with center (3, 2)? Explain.

Graph y ≥ -x^2 - 1. click on the graph until the correct graph appears.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

Bring the fraction a/a-4 to a denominator of 16-a^2
