Answer:
Step-by-step explanation:
- For a horizontal compression, we multiply whole numbers greater than 1 in front of
of the given function.
- For horizontal expansion, we multiply by the reciprocal of the number for horizontal compression, in front of
For example,
If we wanted to <u>horizontally compress</u> , we would multiply by 4 to get
, and
if we wante to <u>horizontally expand</u> , we would multiply by
to get
Since this question asks for horizontal compression, we multiply the of the function by 4. So the function we need is
. The second choice is correct.
The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.
<h3>How to use inverse proportionality to determine building time of a wall</h3>In this question we must use the definition of <em>inverse</em> proportionality, in which the number of workers (), no unit, is inversely proportional to the <em>building</em> time (
), in days.
According to the statement, 6 workers spent 6 days building a wall and there are 24 days left for completion, but 3 more workers entered to reduce building time, which can be represented by the following expression:
In this scenario, the wall can be built in 22 days.
