Here is the three-part question... This counts as ONE homework grade and ONE quiz grade!
a. Amy drew a right triangle with legs whose lengths are the square root of 5 and the square root of 5 and whose hypotenuse is five times the square root of 2. Is this a 45-45-90 triangle? If it is not, explain how you can change the sides so that it is a 45-45-90 triangle.
b. The date December 31, 2043 can be written in the format 12/31/43. This is an example of a true mathematical statement because 12 + 31 = 43. Suppose I wanted to write dates in the 21st century for Valentine’s Day (which is always celebrated on February 14) that will also give me true mathematical statements when writing in this format. There are only two of them this century. What are these two dates? Give your answers in standard format (like 12/31/43 = December 31, 2043).
c. Suppose that you just struck it rich by earning a million dollars. You are given the option of receiving $900,000 right now (because of taxes) or earning an equal amount from the million dollars over the next 25 years (no taxes). Which option would you choose? Explain your answer in at least THREE complete sentences.
Good luck!
