If you are able, typing answers and the work absolutely works! In fact it's better because I'm just checking answers and want to make sure it's all right so just typing from a laptop or something works since I don't need a step by step you understand? thank you sm in advance I really appreciate it!!

Answer each of the problems. Make sure to show all your work. 1) A pump is used to fill an inflatable mattress at a constant rate of 0.25 cubic feet per second. If the mattress is completely inflated after 1 minute, how much air can the mattress hold? Include units in your answer. 2) The same mattress in Problem 1 is later deflated by opening its release valve. Air escapes at a rate of r(t) = 0.25e-005, where r is in cubic feet per second. Assuming the mattress is still completely inflated when the valve is opened, how much air is released in the first 30 seconds? 3) Refer to the information in Problems 1 and 2. How much air remains in the mattress after 45 seconds from opening the release valve? 9.2 4) A projectile travels at a velocity of v(() = 45- 32t, where v(() is measured in feet per second. Find the change in position (displacement) of the projectile on the time interval [0, 3]. Include units in your answer. 5) Refer to the scenario in Problem 4. If the projectile started with an initial position at s(0) = 25 feet, find its position at t = 3 6) The graph of g'(f) on the interval [0, 10] is shown below. If o(0) =
