<h3>(14, 20) is the ordered pair of the function f(x)</h3>
<em><u>Solution:</u></em>
Given that,
(20, 14) is an ordered pair of the inverse of f(x)
We have to find the ordered pair of the function f(x)
In an inverse funciton, the domain of f(x) becomes the range and range of f(x) becomes the domain
To find the ordered pair of the function f(x), we swap the variables x and y
(y, x) of inverse of f(x) becomes (x, y) of f(x)
Therefore, (14, 20) is the ordered pair of the function f(x)
20 because of the whole is 40 and the shaded part is by 20 you just take half of 40 and you get 20
First we need to determine the circumference of the bath.
Circumference = Diameter X pi
6(pi) = 18.84 feet
and the girls want to put perches that are at least 3 feet between each other so you can just divide the circumference by 3
18.84 / 3 = 6.28 so 6
If you don't understand the concept then think of it like this, if you have in total 18.84 feet and you want to place something down every 3 feet then start subtracting 3 from your total till you can't add anymore perches.
18 - 3 = 15
15 - 3 = 12
12 - 3 = 9
9 - 3 = 6
6 - 3 = 3
3 - 3 = 0
We subtracted 3, SIX times so we added 6 perches
AB = sqrt(10^2 - 4^2) = sqrt(100 - 16) = sqrt(84) = sqrt(4 x 21) = 2sqrt(21) = 2 radical 21.
For #3, it's 5.4 because you divide the total amount of money made by the amount of money earned per hour.
49.95/9.25=5.4 hours
