The pressure in a cylinder is given by k t P(t) = 101 + where P is in kilopascals (WebAssign abbreviation kPa) and t is in minutes. Assume that t 1 and k is constant. At time t = 7:5 minutes the pressure is changing at -1.35 kPa/min. Find k. k= Your answer should be accurate to 1 decimal place and must include units. If you are not sure how to enter unusual combinations of units;
