Answer:

n= -17

Step-by-step explanation:

Simplifying

5 + n + (15 + -2) = 0

Combine like terms: 15 + -2 = 13

5 + n + (13) = 0

5 + n + 13 = 0

Reorder the terms:

5 + 13 + n = 0

Combine like terms: 5 + 13 = 18

18 + n = 0

Solving

18 + n = 0

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-18' to each side of the equation.

18 + -18 + n = 0 + -18

Combine like terms: 18 + -18 = 0

0 + n = 0 + -18

n = 0 + -18

Combine like terms: 0 + -18 = -18

n = -18

Simplifying

n = -18

In 2013, the moose population in a park was measured to be 5,100. By 2018, the population was measured again to be 5,200. If the

Answer:

$P(t) = 5100e^{0.0039t}$

Step-by-step explanation:

The exponential model for the population in t years after 2013 is given by:

$P(t) = P(0)e^{rt}$

In which P(0) is the population in 2013 and r is the growth rate.

In 2013, the moose population in a park was measured to be 5,100

This means that $P(0) = 5100$

$P(t) = 5100e^{rt}$

By 2018, the population was measured again to be 5,200.

2018 is 2018-2013 = 5 years after 2013.

So this means that $P(5) = 5200$ .

We use this to find r.

$P(t) = 5100e^{rt}$

$5200 = 5100e^{5r}$

$e^{5r} = \frac{52}{51}$

$\ln{e^{5r}} = \ln{\frac{52}{51}}$

$5r = \ln{\frac{52}{51}}$

$r = \frac{\ln{\frac{52}{51}}}{5}$

$r = 0.0039$

So the equation for the moose population is:

$P(t) = 5100e^{0.0039t}$
