Write an equation to represent the relationship shown in the table. The table has two rows. The first row is labeled x. The second row is labeled y. x six, y forty-two. x seven, y forty-nine. x eight, y fifty-six. x nine, y sixty-three.

Enter the correct equation in the box.

What basic trigonometric identity would you use to verify that sin x cos x tan x =1-cos^(2)x?

The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.

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?
