I HAVE TO TURN THIS IN IN 2 HOURS!!! PLEASE HELP!! I have the graph "y=(1/2)|x-3|-2" graphed but the question also wants the solutions. What solution is it referring to? (I have another graph with the equation of "3|x+4|-5=-2" (again it is graphed already but it also wants the solutions) and the equation "(2/3)|x+4|+3=2" (graphed but I need the solutions)) I don't know what it means by solutions. An explanation and a solved example would be appreciated

We have two coins, A and B. For each toss of coin A, we obtain Heads with probability 1/2 ; for each toss of coin B, we obtain Heads with probability 1/3 . All tosses of the same coin are independent. We toss coin A until Heads is obtained for the first time. We then toss coin B until Heads is obtained for the first time with coin B. The expected value of the total number of tosses is:

Over the past several years, the owner of a boutique on Aspen Avenue has observed a pattern in the amount of revenue for the store. The revenue reaches a maximum of about $ 50000 in June and a minimum of about $ 29000 in December. Suppose the months are numbered 1 through 12, and write a function of the form f(x)=Asin(B[x−C])+D that models the boutique's revenue during the year, where x corresponds to the month. If needed, you can enter π=3.1416... as 'pi' in your answer. Please show your work/explain your steps!

Suppose someone takes out a home improvement loan for $30000. The annual interest on the loan is 6% and is compounded monthly. The monthly payment is $600. Let a denote the amount owed at the end of the nth month. The payments start in the first month and are due the last day of every month - this means in a given month interest is added first, and then the payment is applied to the resulting loan Balance. (a) Give a recursive definition for a,. including the recurrence relation and the base case. (You can readily check your thinking by setting up a spreadsheet to track the loan balance.) (b) Suppose that the borrower would like a lower monthly payment. How large does the monthly payment need to be to ensure that the amount owed decreases every month?

The true statement "If x is a rational number and y is a rational number, then the sum of x and y is a rational number" is often confused with the converse "If the sum of x and y is a rational number, then x is a rational number and y is a rational number." In this case, the converse is not always true. Which statement is false? A) If the sum of x and y is a rational number, then x must be a rational number. B) If x = 3.5 and y is a whole number, then the sum of x and y must be a rational number. Eliminate C) If x is an even integer and y is an odd integer, then the sum of x and y must be a rational number. D) If the sum of x and y is a rational number, then x may be a rational number or x may be an irrational number.
