1 Math Review Chapter 3 Name Re - do all handouts and do the review from the book. Remember to SHOW ALL STEPS. You must be able to solve analticall and then verif with a graph. Find the rational zeros of the polnomial. List an irrational zeros correct to two decimal places. 1) f() = Match the polnomial function graph to the appropriate zeros and multiplicities. ) Do not use the calculator. Eplain our reasoning A) -1 (multiplicit 3), 5 (multiplicit 3) B) -1 (multiplicit 3), 5 (multiplicit ) C) -1 (multiplicit ), 5 (multiplicit 3) D) -1 (multiplicit ), 5 (multiplicit ) Use regression to solve the problem. Round numbers to the nearest hundredth. 3) The first column shows the independent variable (). The second column shows the dependent variable () Solve the problem. Find the quadratic regression equation. (Use our calculator: STAT, CALC, choose the quadratic model) (This is similar to the linear regression done in section.) 4) A flare fired from the bottom of a gorge is visible onl when the flare is above the rim. If it is fired with an initial velocit of 19 ft/sec, and the gorge is 560 ft deep, during what interval can the flare be seen? (h = -16t + vot + ho.) 1

(c) What price should the compan charge to maimize revenue? 6) The number of mosquitoes M(), in millions, in a certain area depends on the June rainfall, in inches: M() = What rainfall produces the maimum number of mosquitoes? Solve algebraicall. Then check the work with the calculator. Show our graph. 7) The concentration C of a certain drug in a patient's bloodstream is given b 30t t (a) Find the horizontal asmptote of C(t). (b) Using a graphing utilit, determine the time at which the concentration is highest. 8) A piece of rectangular sheet metal is 8 inches wide. It is to be made into a rain gutter b turning up equal edges to form parallel sides. Let represent the length of each of the parallel sides. For what value of will the area of the cross section be a maimum (and thus maimize the amount of water that the gutter will hold)? If necessar, round to decimal places. 9) A developer wants to enclose a rectangular grass lot that borders a cit street for parking. If the developer has 30 feet of fencing and does not fence the side along the street, what is the largest area that can be enclosed? 10) A ball is thrown verticall upward with an initial velocit of 19 feet per second. The distance in feet of the ball from the ground after t seconds is s = 19t - 16t. For what interval of time is the ball more than 43 above the ground?
