Change f(x) y to make it easier.
y = 1/2x-3
switch y and the x.
x = 1/2y-3
Add 3 to both sides
x+3 = 1/2y
Multiply both sides by 2.
2x+6 = y
Therefore, f^-1(x) = 2x+6
The answer is 14 or 15 qe
Answer:
x = 73.17
Step-by-step explanation:
To solve this problem we are going to have to use trig function
The three main trig functions are
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Hypotenuse
( where hypotenuse = longest length , opposite = side length opposite of angle and adjacent = other side length )
Here, we are given two side lengths and we want to find an angle.
We are given the hypotenuse and its adjacent ( we know this because we are not given its opposite )
When you have the adjacent and hypotenuse you use cosine.
So we have Cos"x" = adj / hyp
adj = 22 and hyp = 76
So Cos"x" = 22/76
==> take the inverse of cos to both sides
x = 73.17 ( rounded to the nearest hundredth )
and we are done!
The absolute value is 5/13
Area accomodate just the surface of a figure ( Length and width ) while Volume accomodate
the surface and edge of a figure ( length and witdth and height )
