Hope this helped!!!
Answer:

Step-by-step explanation:
So we have the function:

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

Add 9 to both sides:

Take the natural log of both sides:

The right side cancels:

Divide both sides by 6:

And we're done!
Answer:
SAS
Step-by-step explanation:
Looking for the third side given the other two sides and the angle between them
c² = a² + b² - 2abcosC
2/3 of an hour is 40 minutez, therefore that times 4 equals to 160 minutes or 2h and 40 minutes. The answer should be 2-3
