Answer:

7pi/2

Step-by-step explanation:

If was a full, the circumference or the arc length would be 2pi*r where r in this case is 7 so it would be 14pi.

Now this only a quarter of that, so this arc length is actually 14pi/4.

This can be reduced 14pi/4 =7pi/2

15 cm 7.5cm 10 cm 5 cm

Schach [20]

Answer:

7.5 = OM

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opposite side / hypotenuse

sin 30 = OM / UN

sin 30 = OM / 15

15 sin 30 = OM

7.5 = OM

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 t 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 t can be calculated as,

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

Now, final population after 2019 can be calculated as,

$undefined$

What are possible units for impulse? Check all that apply.

vivado [14]

Answer:

N s or Kg m/s

Step-by-step explanation:

Impulse is the product of the force and time or mass and velocity.

Impulse = force x time , or

Impulse = mass x velocity

Therefore; the SI units of impulse is newton-second (N · s). Reduced to base units in the International System of Units ( SI ), a newton-second is the equivalent of a kilogram-meter per second (kg · m/s).
