To calculate:the expected average value of the 13 discrete temperatures.

Answer to Problem 20E
The average is less than trapezoidal rule approximation.
Explanation of Solution
Given information:
The average temperature to be 65.17 degrees when used the integral approximation, yet the average of the 13 discrete temperatures is only 64.69 degrees. Considering the shape of the temperature curve
Formula used:
The sum of all values and divided by total number of quantities.
Calculation:
The calculation of the average from basic average formula that is sum of all values and divided by total number of quantities then, average gives equal weight to all values. Here at end of interval, average gives equal weight to low values. So the value becauseof average is less than trapezoidal rule approximation.
Conclusion:
The average is less than trapezoidal rule approximation.

Meanwhile, a firefighter is climbing up the ladder at a rate of 2 feet/sec. When the firefighter has climbed up 6 feet of the ladder, the ladder makes an angle of л/3 with the ground. Answer the two related rates questions below. (Hint: Use two carefully labeled similar right triangles.) (a) If h is the height of the firefighter above the ground, at the instant the angle of the ladder with the ground is л/3, find dh/dt= feet/sec. (b) If w is the horizontal distance from the firefighter to the wall, at the instant the angle of the ladder with the ground is л/3, find dw/dt= feet/sec.arrow_forwardTwo cars start moving from the same point. One travels south at 60 mi/h and the other travels west at 25 mi/h. At what rate (in mi/h) is the distance between the cars increasing four hours later? Step 1 Using the diagram of a right triangle given below, the relation between x, y, and z is z² = x²+ +12 x Step 2 We must find dz/dt. Differentiating both sides and simplifying gives us the following. 2z dz dt dx 2x. +2y dt dx dy dz x +y dt dt dt 2z dy dt × dx (x+y dt dy dtarrow_forward
