Assume that k = 4.8 10.1 1) Evaluate. [ f(x) dx = [ 2.5 2) Find the value of b such that f ( x ) dx = 21 ? 2 ROUND THIS ANSWER TO 2 DECIMAL PLACES. b ~A train is traveling at a velocity of 90 feet per second when it hits its brakes. It slows down at a constant rate of 0.8 feet per second each second until it stops. DO NOT ROUND YOUR ANSWERS. 1) How long will it take the train to stop? Answer in decimal form. It will take the train |:| seconds to stop. 2) After it hits its brakes, how many feet will it travel before it stops? Answer in decimal form. The train will take D feet to stop. Using the graph of the function H(x) below, find the following. 10 + -10 10 w Evaluate H(x) dx = 7 -6.3 ROUND TO ONE DECIMAL PLACE if necessary. Clear all
