Another balloon story A hot-air balloon is 150 ft above the ground when a motorcycle (traveling in a straight line on a horizontal road) passes directly beneath it going 40 mi/hr (58.67 ft/s). If the balloon rises vertically at a rate of 10 ft/s, what is the rate of change of the distance between the motorcycle and the balloon 10 seconds later?

- Start with a circle of radius r=9. Form the two shaded regions pictured below. Let f(6) be the area of the shaded region on the left which has an arc and two straight line sides. Let g(6) be the area of the shaded region on the right which is a right triangle. Note that the areas of these two regions will be functions of 6; r=9 is fixed in the problem. 0 f(0) (a) Find a formula for f(6)= | | (b)Find a formula for g(6)= lim ƒ (6) (c) 80 = lim g (0) (d) 80 = lim (e) [f(8)/g(6)]= 0 g(0)arrow_forwardMy teacher's answer is: 4a⁷b⁶arrow_forwardExplain to me why the answer is: 4a⁷b⁶ if not then defend yoursarrow_forward
