a.
To write an expression for the total feet below the surface the camera would be after it is lowered.
a.

Answer to Problem 38IP
The expression for the total feet below the surface the camera would beafter it is lowered is,
Explanation of Solution
Given information:
The camera is 7 feet below the surface and it is lowered an additional f feet.
The expression for the total feet below the surface the camera would beafter it is loweredcan be obtained as,
Therefore,
The expression for the total feet below the surface the camera would beafter it is lowered is,
b.
To find the depth of the camera when it isfurther lowered down and show a table.
b.

Answer to Problem 38IP
The depth of the camera when it is further lowered down is obtained in the table form as,
Lowered down in feet | Depth of the camera |
5 feet | 12 feet |
8 feet | 15 feet |
10 feet | 17 feet |
12 feet | 19 feet |
Explanation of Solution
Given information:
The camera is 7 feet below the surface and it can be further lowered down 5,8,10 or 12 feet.
Calculation:
The depth of the camera when it is further lowered down can be obtained as,
If further lowered down 5 feet below the surface,
If furtherlowereddown 8feet below the surface,
If further lowereddown10 feet below the surface,
If further lowered down 12 feet below the surface,
Therefore,
The depth of the camera when it isfurther lowered down is obtained in the table form as,
Lowered down in feet | Depth of the camera |
5 feet | 12 feet |
8 feet | 15 feet |
10 feet | 17 feet |
12 feet | 19 feet |
