two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 148 ft, and ball 2 is dropped from a height of 203 feet. Use thr function f(t) = -16t^2+h to determine the current height, f(t), a ball is dropped from a height h, over a given time t. When does ball 1 reach the ground? Round to the nearest hundredth.

A multiple choice test 30 questions, and each question has 5 answer choices (exactly one of which is correct). A student taking the test guesses randomly on all questions. Using the Normal approximation with continuity correction, determine the approximate probability that the student will get at least as many correct answers as he would expect to get with the random guessing approach.

69. Suppose that you currently have one credit card with a balance of $10,000 at an annual rate of 24.00% interest. You have stopped adding any additional charges to this card and are determined to pay off the balance. You have worked out the formula bbn = b0r n − R(1 + r+r2 +....+ r n−1), where b0 is the initial balance, bn is the balance after you have maden payments, r= 1 + i, wherei is the monthly interest rate, and R is the amount you are planning to pay each month. a. What is the monthly interest rate i ? What is the growth rate, r ?
