(a)
To sketch:The graph of the continuous function.
(a)

Explanation of Solution
Given information:
A continuous function that is
Graph:
The sigma function is defined as the function which has the value -1for the negative argument and 0 when the argument is 0 and 1 for the positive argument.
The graph for the given continuous function
Interpretation:
From the graph it is obtained that the value -1 has negative argument and 1 has positive argument. The graph is increasing and decreasing with respect to the argument value.
(b)
To find:The formula for the function.
(b)

Answer to Problem 27E
The formula for the function is given below as,
Explanation of Solution
Given information:
A continuous function that is
Calculation:
To determine the formula for the function as follows,
Consider the slope for (0.1.l) as 10, and the linear function for
The formula for the function is given below as,
(c)
The input have to be to 0 for the output to be within 0.1 for 0.
(c)

Answer to Problem 27E
The input should be within -0.01 to 0.01 for the output to be within 0.1 to 0.
Explanation of Solution
Given information:
A continuous function that is
Calculation:
The given function is
To determine the input at
Similarly, consider
From the two values of
Hence, the input should be within -0.01 to 0.01 for the output to be within 0.1 to 0.

Tank A contains 200 liters of water in which 50 kilograms of salt has been dissolved and Tank B contains 100 liters of pure water. Water containing 1kg of salt per liter is pumped into Tank A at the rate of 5 liters per minute. Brine mixture is pumped into Tank A from Tank B at the rate of 3 liters per minute and brine mixture is pumped from Tank A into Tank B at the rate of 8 liters per minute. Brine is drained from Tank B at a rate of 5 liters per minute. (a) Draw and carefully label a picture of the situation, including both tanks and the flow of brine between them.
