Question

To clean windows of skyscrapers, some companies use a carriage. A carriage is mounted on a railing on the rook of a skyscraper and moves up and down using cables. A crew plans to start at the 12th floor and move the carriage down as they clean the windows on the west side of a building. If the crew members clean windows at a constant rate of 0.75 floor per hour, the absolute value function f(t) = 0.75t-12 represents the number of floors above ground level that the carriage is after t hours. Graph the function. How far above ground level is the carriage after 4 hours?

Answer 1

Answer: -9 OR 15 (See explanation)

Step-by-step explanation:

Substitute 4 for t since t represents hours:

0.75t - 12 --> 0.75(4) - 12 =

3 - 12 =

-9

Something seems off, if you meant to put +12 instead of -12, then the answer is 15. Hope this helps, please consider making me Brainliest.
