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:
Reaches a maximum height of 235.00 feet in 3.75 seconds.
Step-by-step explanation:
The height of the boulder, h, in feet after t seconds is given by the function is given by :
.....(1)
For maximum height, put 
i.e.
Put t = 3.75 in equation (1). So,
So, the boulder's maximum height is 235 feets and it takes 3.75 s to reach to its maximum height.
Answer:
1/2 person
Step-by-step explanation:
We can use a ratio to solve
6 rolls 1 roll
------------ = -------------
3 people x people
Using cross products
6x =3
Divide each side by 6
6x/6 = 3/6
x = 1/2
1 roll will solve 1/2 person
Y=3x+19
You add 3x to each side. Because your trying to get y by its self like y=mx+b.
Answer:
Step-by-step explanation:
Let the x be the number of hours after noon.
<u>We have the following equation:</u>
- 14.83 + 0.12(x + 3) = 15.33 - 0.15x
- 14.83 + 0.12x + 0.36 = 15.33 - 0.15x
- 0.12x + 0.15x = 15.33 - 15.19
- 0.27x = 0.14
- x = 0.14/0.27
- x ≈ 0.5
