The answer is already given in your question. The inverse of a function
f is f-1, g is g-1, h is h-1 and i is i-1.
To explain why the inverse of
<span>f = {(1,2), (2,3), (3,4), (4,5), (5,6), (6,7)}
is
f-1 = </span><span>f -1 = {(2,1), (3,2), (4,3), (5,4), (6,5), (7,6)}
and that of the other functions to their corresponding inverses is because of the definition of the inverse of a function which is
f = (x, y)
f-1 = (y, x)
Simply, the x and y coordinates of a function are interchanged to get the inverse of the function.</span><span />
Answer:
144
Step-by-step explanation:
The ratio of men to women working for a company is 8 to 5.
Total men and women working as per the ratio is 8+5 = 13
So the ratio of men to total is
the ratio of women to total is
there are 234 employees total
To find the number of men works , we make a proportion
Cross multiply it
8 * 234 = 13x
1872 = 13x
Divide by 13 on both sides
x= 144
