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.
Let
A(2,5)
B(13,11)
C(13,5)
using a graph tool
see the attached figure
area of triangle=AC*BC/2
distance AC
d=√[(y2-y1)²+(x2-x1)²-----> d=√[(5-5)²+(13-2)²---> d=√[11²]
dAC=11 units
distance BC
d=√[(y2-y1)²+(x2-x1)²-----> d=√[(5-11)²+(13-13)²---> d=√[-6²]
dBC=√36 units-----> dBC=6 units
area of triangle=AB*BC/2-----> 11*6/2----> 33 units²
the answer is
33 units²
The coordinates plane is illustrated below.
<h3>How to illustrate the information?</h3>
A coordinate plane simply means the graphing system for points and lines.
Based on the information given, the area of teb triangle will be:
= 1/2 × b × h
= 1/2 × 11 × 20
= 110
