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.
Answer:
<em>r=3x</em>
Step-by-step explanation:
<u>The Volume of a Cone</u>
The volume of a cone of radius r and height h is:
We are given the volume of a cone is
Equating:
Multiplying by 3:
Simplifying by pi:
Since h=x:
Dividing by x:
Taking square roots:
Thus: r=3x
By definition, the circumference is given by:
C = 2 * pi * R
Where,
R: Radio
Substituting values we have:
C = 2 * pi * (27/2)
C = 84.82300165 in
Round to the nearest whole number:
C = 85 in
Answer:
The circumference of the wheel is:
B. about 85 inches
Hello Rebelkid2004, 532 with a remainder
is, gives remainder 0 and so are divisible by 1, we get factors of 532 numbers by finding numbers that can divide 532
without remainder or alternatively numbers that can multiply together to
equal the target number being converted.
Ah hah ! People on Brainly are always asking us where they can
use this stuff in real life. HERE is a perfect example of where
you can use Least Common Multiple in real life . . . when you're
buying hot dogs and buns !
When they come in packs, with different numbers in each pack
but you want to wind up with the same number of each item,
the number of each item that you should buy is the LCM of
the numbers in each pack.
Yadira's mom absolutely aced her math in Middle School, so she
knows right away that the LCM of 9 and 12 is 36 . This tells her
that she should buy 36 hot dogs (3 packs) and 36 buns (4 packs).
