Answer:
16 days
Step-by-step explanation:
24 men works 8 hours a day to complete a work in 15 days. While 20 men works at 9 hours per day to complete the same work in x days. We can find the number of days it took the 20 men by using the expression below:
24 men * 8 hours/day * 15 days = 20 men * 9 hours/day * x days
Therefore it took 20 men working 9 hours/day, 16 days to complete the same work
Hence, the inverse of the given function is
<h2>What is a function?</h2>
function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). A function has three parts, a set of inputs, a set of outputs, and a rule that relates the elements of the set of inputs to the elements of the set of outputs in such a way that each input is assigned exactly one output.
<h3>How to solve?</h3>
given function,
q(x) = 10
say y=q(x)
now we have,
y = 10
=
raising to 5th power on both sides,
= x - 2
x = + 2
