Ket [755]

Answer:

96%

Step-by-step explanation:

now It's the turn of increasing

80%x + 20% * (80% x) = 80%x + 16%x = 96% x

Consider the tables created using an initial investment of $1,000 and quarterly compounding of interest.
Andru [333]

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.
