3. [-/8 Points] DETAILS SCALCET9 5.1.009.MI.SA. This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Tutorial Exprolca The speed of a runner increased steadily during the first three seconds of a race. Her speed at half-second Intervals Is given in the table. Find lower and upper estimates for the distance that she traveled during these three seconds. t (s) 0.5 1.5 2.0 2.5 3.0 v (ft/s) 6.2 10.8 18.1 19.4 20 2 Click horn to boging Need Help? Damn Masks 4. [-/3 Points] DETAILS SCALCET9 5.1.010. The table shows speedometer readings at 10-second Intervals during a 1-minute period for a car racing at the Daytona International Speedway In Florida. Time (s) Velocity [mi/h) 0 6'THT 10 167.0 20 107.6 30 3H.8 125.5 50 176. 60 176.6 (2) Estimate the distance (in ml) the race car traveled during this time period using the velocities at the beginning of the time Intervals. (Round your answer to three decimal places.) (b) Give another estimate (in ml) using the velocities at the and of the time periods. (Round your answer to three decimal places.) J ml (c) Are your estimates in parts (a) and (b) upper and lower estimates? Explain. O The velocity is Increasing on the given interval, so the estimate in part (a) is an upper estimate and the estimate in part (b) is a lower estimate. O The velocity is neither increasing nor dec sing on the given interval, so the estimates in parts (a) and (b) are neither upper nor lower estimates. O The velocity is Incre sing on the given interval, so t : In part (a) is a lower estim hate In part (b) is an upper estimate. O The velocity is decreasing on the given Interval, so estimate In part (a) is a lower estimate a estimate In part (b) is an upper estimate. The velocity is decreasing on the given interval, so the estimate In part (a) is an upper estimate and the estimate in part (b) is a lower estimate. Need Help? Band in
