BCDAt a concert, a band is playing on a platform that extends P feet from a wall behind the band, and theplatform is rising from ground level, as shown in the figure above. A light source is L feet from the wall, andthe platform casts a lengthening shadow on the wall as the platform rises. At time t seconds, the platformis h feet above the ground, and the height of the shadow is s feet. The quantities are related by the equation(h+s) = 8, where L and Pare constants. Which of the following best expresses the rate of changeof h with respect to time in terms of the rate of change of s with respect to time?dhdts ftdh = 1 dh ft=8 S18-dL dsP dt8-P ft-dsdt.L ft

use the Y axis to represent distance and the X axis to represent time. Four race cars are heading for the finish line. Car 11 is in the lead and has 1.2 miles to go. But he has engine trouble and is only traveling at a speed of 130 mph. How long before car 11 crosses the finish line (where distance remaining = 0). Car 32 is in second and is .1 miles behind Car 11 (he has 1.3 miles to go). He is traveling at a speed of 140 mph. Add that line to your graph. Car 53 is in third and is .3 miles behind the leader (1.5 miles to go). He is traveling at a speed of 165 mph. Car 94 is in last place, and is .5 miles behind the leader (1.8 miles to go). He is gaining fast, at a speed of 185 mph. Remember, the x axis is time, and the y axis is distance to go.

When there is no wind, a runner is able to run 10 000 m at an average speed of x m/s. When he runs with a tailwind, his average speed increases by 0.05 m/s and it takes him 15 s less to run the 10 000 m. The equation shown below represents this relationship. 10 000 10 000 x+0.05 X = 15, x > 0 6. When there is no wind, find the runner's average speed, to the nearest hundredth of a metre per second.
