Pre-calculus question: assuming a current world population of 6 billion people, an annual growth rate of 1.9% per year, and a worst-case scenario of exponential growth, what will the world population be in 50 years? a) 15.38 billion b) 18.73 billion c) 14.25 billion d) 16.45 billion i think that i need to use the exponential growth formula: p(t)=p₀a^t where p₀=6 billion and t=50 years but not sure what a (the base) is nor how to use the annual growth rate 1.9% information.

You already have figured the main idea. In this case, the population is growing 1.9% a year. This word can be translated into: multiplied by 101.9% (100+1.9%). That means the P0 is 6 bill, the base is 101.9%(or 1.019) and the time is 50 years. The calculation would be:
P(t)=P₀a^t
P(t)=6 billion * 101.9%^50= 6 billion * 2.56276= 15.38 billion

1250mph you'd tear through the crust of the earth and create a supervolcano to end all of us.

Step-by-step explanation:

Never fall that fast when parachuting, only you can prevent supervolcanoes.
