1. If a car travels in a straight line with an average velocity of 55mph for 2 hours, then_65mp'h for 3 hours, then 61mph for 2 hours, then 68mph for 3 hours, how far did it go on the trip? If It started at the 170-mile mark, where is it now? 2. If a city population grows an average of 840 people/year for 8 years, then 920people/year for 3 years, how much did it grow in that span? If the city originally had 26500 people, how many does it have now? 3. If you buy 8 shirts for an average price of 22 dollars per shirt, then you buy 5 shirts for an average of 27 dollars per shirt, how much did you spend on all these shirts? If you already spent $270 on shirts, how much did you spend on shirts in total? 4. If a car travels an average of 28 miles per gallon on 12 gallons, then 25 miles per gallon on 11 gallons, how many miles did it go using that gas? If the car was new, how many total miles has it traveled? 5. If an author averages 245 pages per book for 6 books, then 180 pages per book for 3 books, then 205 pages per book for 3 books, how many total pages were in those books? If the author had already published 1150 pages, how many total pages has the author published? An = 2.6, AX2 = 1.8, m1 = 12.7, m2 = 10.1 (a) find Ay 0)) given starting point (4.9, 72.6), find y. A factory is mixing paste, and they measure volume Vin liters and mass m is kg. They add 3.6 liters of volume of a paste with average density 2.7 kg/liter, and 1.6 liters of a paste at 2.2 kg/liter, and 8.1 liters of a paste at 1.9 kg/liter. How much mass was added? If it was added to 13.7kg of paste, what mass of paste is there now? Draw a graph of the situation, and use notation to label th e individual changes and the total change for both volume Vand mass m. 8. If y increases with a slope of 3 from x=1 to x23, then at a slope of IA for x=3 to x=7, how much did y change in that span? If y started at -3, what is y now? Draw a graph of the situation, and use notation to label the individual changes and the total change for both x and y. 9. We know that (x5)' = 5x4. If the rate is 5x\
