Arlecino [84]

Answer:

  A.  3.66 feet

Step-by-step explanation:

Using trigonometry, we know that ...

  BC = DC·tan(30°)

  AC = DC·tan(45°)

  AB = AC -BC = DC(tan(45°) -tan(30°))

  AB = 5√3·(1 -√3/3) = 5(√3 -1)

  AB ≈ 3.66 . . . feet

Find the area of the sector.
Rasek [7]

Answer:

104.72 m^2.

Step-by-step explanation

I'm taking the angle to be 30 degrees.

Area of sector = area of the circle * 30/360

= pi*20^2 * 30/360

= 400pi * 1/12

= 104.72 m^2.

The population of algae in an
Westkost [7]

Given:

Initial population = 100 algae

Growth rate = 30% per day.

Time = 5 days

To find:

The future amount of population.

Solution:

The exponential growth model is

y=a(1+r)^t

where, a is the initial value, r is the rate of interest in percent and t is time period.

Substituting the given values, we get

y=100(1+\dfrac{30}{100})^5

y=100(1+0.30)^5

Now, solve this.

y=100(1.30)^5

y=100(3.71293)

y=371.293

Therefore, the future value is 371.293 algae.
