Answer:
Step-by-step explanation:
A way to find the inverse function is to swap the x and y (f(x)) in the equation.
We can check that it is an inverse function by using a property of inverse functions:
If we plug in the f(x) function into the variable x of the inverse function, we should end up with x
It checks out!
Sum means add
(x+5) + (-4x-2) + (2x-1)
=-3x+3+(2x-1)
=-x+2
Answer:
c = <u>0.5 cm</u>
Step-by-step explanation:
Using the Sine rule in the triangle, then
= ( cross- multiply )
c × sin105° = 2 × sin15° ( divide both sides by sin105°
c = ≈ 0.5 cm ( to the nearest tenth )
