An investment services company experienced dramatic growth in the last two decades. The following models for the company's revenue R and expenses or costs C (both in millions of dollars) are functions of the years past 1990. R(t) = 21.4e0.131t and C(t) = 18.6e0.131t (a) Use the models to predict the company's profit in 2020. (Round your answer to one decimal place.)(b) How long before the profit found in part (a) is predicted to double? (Round your answer to the nearest whole number.) years after 1990

a) 138.32 and b) 35 years approx.

Step-by-step explanation:

Since we have given that

So, Profit is given by

Difference in years of 1990 and 2020=30

So, Profit becomes :

(b) How long before the profit found in part (a) is predicted to double? (Round your answer to the nearest whole number.) years after 1990.

So, profit doubles , we get :

Hence, a) 138.32 and b) 35 years approx.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
