Answer: The formula for exponential growth is y = a(1 + r)^x, and the formula for exponential decay is y = a(1 - r)^x, with r being the rate of growth/decay. :)
Answer:

Step-by-step explanation:
To calculate the angles of the given triangle, we can use the law of cosines:

Then, given the sides a=2, b=9, and c=8.

For B:
