Find the perimeter of the figure to the nearest hundredth.<br><br><br> Ps: it is not 30
frutty [35]

Answer:

Perimeter = 36.8 ft

Step-by-step explanation:

<u>Step 1:  Add the straight sides together</u>

3+3+3+3+3+3 = 18 ft

<u>Step 2:  Find the perimeter of the semi-circles</u>

The formula for the perimeter of semi-circle:  1/2 π × d

Diameter = 12 - 3 - 3 = 6, because the whole length is 12 minus the 6 ft of other stuff.

Now, 1/2π * 6 = 9.4 ft

But, there are two semi-circles so it will be 9.4 + 9.4 = 18.8 ft

<u>Step 3:  Add all of them</u>

18 + 18.8 = 36.8 ft

Find the distance between points A = (2, 0) and
allochka39001 [22]

Answer:

  9.2

Step-by-step explanation:

You want the distance between A(2, 0) and B(0, 9).

<h3>Distance</h3>

The distance formula is based on the Pythagorean theorem. It tells you the distance between (x1, y1) and (x2, y2) is ...

  d = √((x2 -x1)² +(y2 -y1)²)

For the given points, this becomes ...

  d = √((0 -2)² +(9 -0)²) = √(4+81) = √85

  d ≈ 9.2

The distance between A and B is about 9.2 units.

Population a current census shows that the population of a city is 3.5 million using the formula p= aert find the expected popul
Yuki888 [10]

Answer: the expected population of the city in 30 years is 5470781

Step-by-step explanation:

The population growth is exponential. The growth rate is exponential. We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 3.5 × 10^6

r = 1.5% = 1.5/100 = 0.015

t = 30 years

Therefore,

A = 3.5 × 10^6(1 + 0.015)^30

A = 3.5 × 10^6(1.015)^30

A = 5470781
