Answer:
x amount of money determines y number of hours to make a painting of that cost.
Step-by-step explanation:
The inverse of a function, is the function or rule formed by reflecting the line over y=x. This means essentially that all (x,y) values from the original function switch to (y,x).
(x,y)--->(y,x) in the new function.
If the function determines the amount (y) he makes in x hours. The inverse determines how many y hours it takes to earn x amount of money.
The constant of proportionality k is given by y = kx.
In your equation, it would be r = km.
Can you now spot it?
Answer:
±
Step-by-step explanation:
We can rewrite as . The half-angle identity for sin tells us that (plus or minus). Now, we can plug in for x. When we do that, we get = ± .
Hope this helped! :)
You just add both fractions because you’re subtracting a negative.
