Chapter 1: Q11E (page 9)

You put some ice cubes in a glass, fill the glass with cold water, and then let the glass sit on a table. Describe how the temperature of the water changes as time passes. Then sketch a rough graph of the temperature of the water as a function of the elapsed time.

Short Answer

Expert verified

The given situation is described below, and the graph is as follows.

Step by step solution

01

Describe the given information

In this exercise, it is required to study the temperature of the water changes as time passes when ice cubes are put in a glass with cold water.

02

Describe how the temperature of the water changes as time passes and sketch the rough graph

It is given that as time passes, the water will be colder because ice melts, then when the ice has melted, the water will slowly warm up to room temperature.

The water is cooling as heat transfers to the ice up to point A. The water and the ice area at about approximately the same temperature, from point A to point B, which is just starting to rise from the heat from the surroundings.

The ice is approximately all melted from point B to point C and the temperature rise more rapidly than that of the surroundings.

From point C, the rise in temperature slows down as it approaches the temperature of the surroundings.

Sketch a rough graph of the temperature of the water as a function of the elapsed time as follows.

The manager of a weekend flea market knows from past experience that if he charges dollars for rental space at the flea market, then the number of spaces he can rent is given by the equation\({\bf{y = 200 - 4x}}{\bf{.}}\)

(a) Sketch a graph of this linear function. (Remember that the rental charge per space and the number of spaces rented can’t be negative quantities.)

(b) What do the slope, the y-intercept, and the x-intercept of the graph represent?

At the surface of the ocean, the water pressure is the same as the air pressure above the water,\({\bf{15}}\;{\bf{lb/i}}{{\bf{n}}^{\bf{2}}}\). Below the surface, the water pressure increases by\({\bf{4}}{\bf{.34}}\;{\bf{lb/i}}{{\bf{n}}^{\bf{2}}}\)for every 10 ft of descent.

(a) Express the water pressure as a function of the depth below the ocean surface.

(b) At what depth is the pressure\({\bf{100}}\;{\bf{lb/i}}{{\bf{n}}^{\bf{2}}}\)?

Determine whether\({\bf{f}}\)is even, odd, or neither. If you have a graphing calculator, use it to check your answer visually.
