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:

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

When a parabola represented by the equation y - 2x 2 = 8 x + 5 is translated 3 units to the left and 2 units up, the new parabol

amid [387]

First rewrite y - 2x 2 = 8 x + 5 as

y = 2x 2 + 8 x + 5 

Complete square and determine vertex.

y = 2(x 2 + 4x + 4) - 8 + 5 

= 2(x + 2) 2 - 3 

vertex at (- 2 , - 3) 

If parabola is translated 3 units to the left and 2 units up its vertex is also translated 3 units to the right and 2 units up .

vertex after translations is at: (-2 - 3 , - 3 + 2) = (-5 , -1)
