The answer to this problem
horrorfan [7]
Work backwards with pythagoras' theorem:
c^2=a^2+b^2
Here, a and b both equal to x. Therefore, you can write this as 8^2=2x^2. So 64=2x^2. Sqrt on both sides to give you 8=2x, hence x=4. However I must warn you that this working out may have a flaw, as I found that x actually equals to 5.66

Can I please get help on numbers 28,32, and 38
Bezzdna [24]

28). 2400-1800= 600

600/2400×100= 25%

32). 3264/272000×100

= 1.2%

38). 2000×5%= 100

3500-2000= 1500

1500×7%= 105

100+105= $205

The inverse of a function is given as √x - 1

<h3>Inverse of a function</h3>

To get the inverse of any function f(x) we need to ensure that it passes the horizontal line test.

Given the following function

f(x) = (x+1)^2

Let y= f(x) to have:

y = (x+1)^2

Replace y with x to have:

x = (y+1)^2

Make y the subject of the formula

√x =y + 1

Subtract 1 from both sides

√x - 1 = y

Swap

y = √x - 1

Hence the inverse of a function is given as √x - 1
