Question

PLZ HELP! A scientist is studying wildlife. she estimates the population of bats in her state to be 270,000. she predicts the population to grow at an average annual rate of 2.9%. using the scientist's prediction, create an equation that models the population of bats, y, after x years.

Answer 1

2.9% times y = x

I do hope that this correct.

Answer 2

I think we need to use the growth or decay formula.

A = Pe^rt

A = ending amount
P = beginning amount
r = growth or decay rate
t = time or term
e = approximately constant 2.71828

Given:
P = 270,000
r = 2.9% growth
y = ending population
x = time in years

create an equation that models the population of bats, y, after x years.

y = Pe^rx

y = 270,000 * 2.71828^0.029x
