Use the following set-up for Problems 5-8:Below is a list of exam scores for a class of 15 students:55, 62, 72, 77, 82, 83, 84, 85, 86, 87, 90, 91, 95, 95, 100How do you find the score at the 30th percentile?

Solve the problem. Unless stated otherwise, assume that the projectile flight is ideal, that the launch angle is measured from the horizontal, and that the projectile is launched from the origin over a horizontal surfaceA projectile is fired at a speed of 1160 m/sec at an angle of 36°. How long will it take to get 29 km downrange? Round your answer to the nearest whole number.

Match the following with their descriptions:

Evaluate the line integral along the curve C.ds, C is the curve r(t) = (6 sin 2t)i + (6 cos 2t)j + 5tk, 2 ≤ t ≤ 4

If r(t) is the position vector of a particle in the plane at time t, find the indicated vector.Find the acceleration vector.r(t) = (7 ln(9t))i + (8t3)j

Consider the following balance sheet for Midtown Bank (Reserve Requirement = 10 percent) Asset                                                                                                    Liability Reserve: 9 million (required)                                                              Deposit: 90 million Loan: 50 million                         Securities: 30 million Other Assets: 11 million                                                                     Bank Capital: 10 million Suppose there is an unexpected deposit outflow of 9 million, what type of crisis do you think the bank is facing? and why? Explain your answer. Please make sure your answer includes a detailed discussion on the changes the assets or liabilities in the balance sheet of the bank.
