a.
To graph: The temperature reading
t | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 |
T | 68 | 65 | 63 | 63 | 65 | 76 | 85 | 91 |
a.
Explanation of Solution
Given information:
It is given that Temperature readings (in °F) were recorded every two hours from midnight to 2:00 PM in Baltimore on September 26, 2007. The time was measured in hours from midnight as shown in table below.
t | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 |
T | 68 | 65 | 63 | 63 | 65 | 76 | 85 | 91 |
Graph:
The graph of T vs t can be drawn by using t as x-axis and T as y-axis. The obtained graphs is as like this,
Interpretation:
The obtained graph shows that first temperature decrease till 8 a.m. and then increases till 14:00 that means till 2 P.M.
b.
To calculate: The temperature at 11:00 a.m. using the given graph.
b.
Answer to Problem 22E
The temperature at 11:00 a.m. is
Explanation of Solution
Given information:
It is given that Temperature readings (in °F) were recorded every two hours from midnight to 2:00 PM in Baltimore on September 26, 2007. The time was measured in hours from midnight as shown in table below.
t | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 |
T | 68 | 65 | 63 | 63 | 65 | 76 | 85 | 91 |
Calculation:
Consider the given graph, the time 11:00 a.m. lies in between 10 to 12 on the x-axis. Now, take the corresponding value of y with respect to x as 11, it is find out to be 80 on this graph.
Therefore, the temperature at 11:00 a.m. is
