I am using Bay County, a county located in the state of Michigan. According to the U.S. Census Bay county had a population of 10
xeze [42]

Given:

The intial population in 2019 is, P₀ = 103126.

The final population in 2020 is, P = 103856.

The objective is to find the population in the year 2039.

Explanation:

The general exponential form of population growth is,

P=P_0\times e^{rt}\text{ . . . . . . . (1)}

Here, t represents the time period.

To find t:

The value of <em>t</em> from 2019 to 2020 can be calculated as,

\begin{gathered} t=2020-2019 \\ t=1 \end{gathered}

To find r :

On plugging the obtained values in equation (1),

\begin{gathered} 103856=103126\times e^{r(1)} \\ \frac{103856}{103126}=e^{r(1)} \\ \log (\frac{103856}{103126})=r \\ r=0.003 \end{gathered}

To find population at 2039:

The time period <em>t</em> can be calculated as,

\begin{gathered} t=2039-2019 \\ t=20\text{ years} \end{gathered}

Now, final population after 2019 can be calculated as,

A bullet with a mass of 0.005 kg is shot at a speed of 40
marin [14]

Answer:

combined velocity of the system = 0.033 m/s.

Step-by-step explanation:

taking the bullet and block as single system since there is no external force involved momentum is conserved .

initial momentum of the bullet = mv

where m is the mass of bullet and v is velocity of bullet.

and initial momentum of block = 0 since its velocity is 0.

therefore initial momentum of the system = mv

                                                                      = 0.005×40

                                                                      = 0.2

when the bullet stick of together with the block let the combined velocity of the system be V

therefore applying conservation of momentum

mv = (M+m)V

0.2=(6+0.005)V

therefore V = 0.033 m/s
