Answer:
(d) The functions are not inverses because for each ordered pair (x, y) for one function, there is no corresponding ordered pair (y, x) for the other function.
Step-by-step explanation:
If functions are represented by a table of ordered pairs, their inverse function is the set of ordered pairs with the x- and y-values swapped.
Here, for (x, y) = (0.75, 1038.18), the pair from the other table that begins to correspond is (y, x) = (0.75, 1057.81). These reversed pairs are not the same, so the functions are not inverses of each other.

<em>Comment on the tables</em>
Table A is for a 5-year investment; table B is for a 7.5 year investment. They cannot be inverses of each other.
The equation used to find surface area of a sphere is A=4 pi radius sqaured
So i believe the surface area is <span>314.16. In terms of pi thats 100pi</span>
Answer: Mean = 9, Standard Deviation = 2.6
Answer:
80m --------> 36 shirts
x m ----------> 45 shirts
Thus by the unitary method, the value of x will be;
36 × x = 80 × 45
x = 80 × 9 × 5 / 36
x = 80×5/4
x = 20 × 5
x = 100 shirts.
