4. A radar gun was used to record the speed of a car (in feet per minute) during selected times in the first 2 minutes of a race. Use a trapezoidal sum with 4 intervals to estimate the distance the car covered during those 2 minutes. Give a 2 decimal place answer and include units. t 0 0.3 1.0 1.6 2 v(t) 0 24.5 27.8 28.3 29.0

Use your GDC to evaluate problem in photo.

You and a companion are driving a twisty stretch of road in a car with a speedometer but no odometer. To find out how long this road is, you record the car's velocity at 10-second intervals. a. Estimate the length of the road using left-endpoint values. ft b. Estimate the length of the road using right-endpoint values. ft Time (s) 0 10 20 30 40 50 60 Velocity (ft/s) 0 32 46 27 37 31 33 Time (s) 70 80 90 100 110 120 Velocity (ft/s) 11 22 21 24 48 40

just the a = s squared i’m a little confused on that
