The radius of a circle is 8 kilometers. What is the area?

Scorpion4ik [409]

Answer:

Area of the circle= $200.96 km^2$

Step-by-step explanation:

Area of a circle= $\pi *r*r$

For radius(r)=8 km

The area of the circle is :

= $\pi *8*8$

As:

$\pi =\frac{22}{7}=3.14$

Area of the circle:

$=3.14*8*8\\\\=3.14*64\\\\=200.96km^2$

The Area of the circle with the radius of $8km$ is $200.96 km^2$

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (2, 3)

Point (2, -6)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{-6-3}{2-2}$
Subtract: $m=\frac{-9}{0}$
Define: m = undef

The population of a small town is decreasing exponentially at a rate of 14.3% each year. The current population is 9,400 people.

levacccp [35]

Answer:

After 2.9 years the town's tax status will change

The towns tax status change within the next 3 years

Step-by-step explanation:

The question below is

Will the towns tax status change within the next 3 years ?

Let

y -----> the population of a small town

t ----> the number of years

we have a exponential function of the form

$y=a(b)^{t}$

where

a is the initial value

b is the base

In this problem

$a=9,400\ people$

$b=100\%-14.3\%=85.7\%=85.7/100=0.857$

substitute

$y=9,400(0.857)^{t}$

Remember that

The town's tax status will change once the population is below 6,000 people

The inequality that represent this situation is

$9,400(0.857)^{t}< 6,000$

Solve for t

$(0.857)^{t}< 6,000/9,400$

Apply log both sides

$(t)log(0.857)< log(6,000/9,400)$

$-0.067t< -0.1950$

Multiply by -1 both sides

$0.067t > 0.1950$

$t > 2.9\ years$

After 2.9 years the town's tax status will change

therefore

The answer is

Yes, the towns tax status change within the next 3 years
