SHOW THE COMPLETE SETUP. A vehicles aerodynamic drag is determined in part by its cross-sectional area, and all other things being equal, engineers try to make this area as small as possible. Estimate the cross-sectional area of James Wordens solar-powered Solectria car at M.I.T. from the diagram below. Use only the middle region with left and right base = 0. The table lists several physical measurements gathered in an experiment to approximate a continuous function x0.000.250.500.751.001.251.501.752.00y4.324.364.585.796.147.257.648.088.14y = f(x). Approximate the integral  EMBED Equation.3 . A new park is being designed with a fishing lake included. The lake will be filled from a spill way branched off from the river that winds through the city. The city must keep the cost below $17,000 for building the lake. One company has made a bid to keep the cost below the $17,000. What is the maximum amount the company can charge per sq.ft.? __________5. A map of an ocean front property is drawn. What is its area? __________6. The data given are adapted from the August, 1991 issue of Road & Track magazine. They give the velocity v(t) of the $239,000 Lamborghini Diablo at time t seconds. Let x(t) denote the distance the car travels for time t, 0 d" t d" 10. Using the trapezoidal rule find x(10). Hint: Multiply your answer by 5280/3600 to change to feet. t v(t) 0 mph 14 mph 27 mph 40 mph 53 mph 64 mph 70 mph 77 mph 84 mph 90 mph 96 mph t(hours)0134789L(t) (people)120156176126150800 ___________7. Concert tickets went on sale at noon (t = 0) and were sold out within 9 hours. The number of people waiting in line to purchase tickets at time t is modeled by a twice-differentiable function L for  EMBED Equation.DSMT4 . Values of L(t) at various times t are shown in the table above. Use a trapezoidal sum with three subintervals to estimate the average number of people waiting in line during the first 4 hours that tickets were on sale. __________8. The graph of a differentiable function f on the closed interval [-3, 15] is shown in the figure above. The graph of f has a horizontal tangent line at x = 6. Find a trapezoidal approximation of  EMBED Equation.3  using six subintervals of length  EMBED Equation.3 = 3. :@dexyz{ u      B N |   Zdp}shh5CJ hCJhA6CJ] hACJh#hxjh#CJEHUjw? h#CJUVaJh#6CJ]h-hxCJaJ h CJjhD@CJEHUjtwP hD@CJUVaJjh#CJU h#CJ h!9CJ-AB        u w | $B&`#$/Ifgd- & F     !
