The value ( in credis) of a piece of jade varies directly as the cube of its volume ( in cm^3). If the value of a piece of jade of volume 2cm^3 is 6720 cedis, find the value of a piece of jade of volume 3.5 cm^3. If the piece of jade of volume 2cm^3 is broken into two parts of equal volume, what would be the percentage loss in its value?

5x + 2 = 12 solve the following equation. then place the correct number in the box provided.

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?

The revenue each season from tickets at the theme park is represented by t(c)=5x. the cost to pay the employees each season is represented by r(x)=(1.5)^x. examine the graph of the combined function for total profit and estimate the profit after four seasons
