Increased by an average of 5% each year since then. (a) Write an iterative rule to model the sequence formed by the profits of Rhonda's business each year.
(b) Use the rule to determine what the annual profits of Rhonda's business can be predicted to be 15
years from the start of her business. Round your answer to the nearest dollar. Do not round until the
end. Show your work.

In trapezoid efgh, m∠hef=(4x2+16)∘ and m∠gfe=(5x2+12)∘. find the value of x so that efgh is isosceles. i'm desperate.

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

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?
