Answer:

\frac{1}{6} a-\frac{1}{6}

Step-by-step explanation:

-\frac{2}{3} a+\frac{5}{6}a-\frac{1}{6}

=-\frac{4}{6} a+\frac{5}{6}a -\frac{1}{6}

= \frac{1}{6} a-\frac{1}{6}

Answer:

\frac{( - 2)}{3} a +  \frac{5}{6}a -  \frac{1}{6}  \\   = \frac{(- 4a) + 5a - 1}{6} =    \frac{(a - 1)}{6}

hope this helps.

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

So

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}
