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
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.
<u>Answer:</u>

<u>Double number line is a diagram used when. quantities have different units.</u>
<u></u>
<u>It shows each of the quantities on its own number line with corresponding pairs of values lined up.The values of each number line are not the same unless there is a 1:1 ratio between them.</u>
<u></u>
<u>some ratios equivalent to 1:3 are;</u>
<u></u>
<u>2:6,3:9,4:12,5:15,6:18,7:21,etc</u>
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

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


Now, solve this.



Therefore, the future value is 371.293 algae.
