Answer:12.57
Step-by-step explanation:
1 cm = 20 feet
the triangle's sides are 4 cm, 5 cm, and 6 cm
multiply the amount of cm with 20 feet
4(20) = 80 feet
5(20) = 100 feet
6(20) = 120 feet
Simplify, divide 10 from all numbers
80/10 = 8
100/10 = 10
120/10 = 12
8, 10, 12 is your answer
hope this helps
If the growth rate is 0.469 per member per day and in the beginnning there are 5 members then the population size after eight days is 108.42.
Given growth of population of protozoa 0.469 per member per day and population in beginninng is 5 members.
We have to find the population afte eight days.
First of all we have to find the function or equation showing sum of population after t days.
Because it is given that the rate is 0.469 per member per day it means it is like compounding.
The equation which shows the sum after compounding is P
where P is the amount in beginning, r is the rate and n is the number of years.
In this problem the equation will be 5
where t is number of days.
We have to put the value of t=8 to find the population after 8 days=
=5
=5*21.68
=108.42
Hence the population of protozoa after 8 days is 108.42.

Step-by-step explanation:
Sin 30° = ½
Cos 30° = √3/2
Sin 60° = √3/2
Cos 60° = ½
Therefore,
(½ + √3/2) - (√3/2 + ½)
![\frac{1 + \sqrt[]{3} }{2} - \frac{ \sqrt{3 + 1} }{ 2 }](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%20%2B%20%20%5Csqrt%5B%5D%7B3%7D%20%7D%7B2%7D%20%20-%20%20%5Cfrac%7B%20%5Csqrt%7B3%20%2B%201%7D%20%7D%7B%202%20%7D%20%20)
