Step 1
The area of a trapezoid is given by the formula: $$Area = \frac{1}{2} (b_1 + b_2) h$$ where $b_1$ and $b_2$ are the lengths of the parallel sides (bases) and $h$ is the height. Show more…

Using rectangles whose height is given by the value of the function at the midpoint of the rectangle's base (the midpoint rule), estimate the area under the graph of the following function, using two and then four rectangles: y = 16 - x^2 between x = -4 and x = 4 For two rectangles, area ≈ (Type an integer or a decimal.) For four rectangles, area ≈ (Type an integer or a decimal.) An object is dropped straight down from a helicopter. The object falls faster and faster but its acceleration (rate of change of its velocity) decreases over time because of air resistance. The acceleration is measured in ft/sec^2 and recorded every second after the drop for 4 sec, as shown. Find the following estimates. a. Find an upper estimate for the speed when t = 4. ft/sec b. Find a lower estimate for the speed when t = 4. ft/sec c. Find an upper estimate for the distance fallen when t = 3. ft

The following table gives the velocity v(t) (in ft/s) at different instances of time t (in s) of a particle moving along the horizontal axis: Using the information in the table, approximate the change in position from t = 0 to t = 12 using rectangles and lower-sum (underestimate): 108
