Answer:

Step-by-step explanation:
To find:
The value of
= ?
Solution:
Kindly consider the equilateral
as attached in the answer area.
Let the side of triangle =
units
Let us draw the perpendicular from vertex A to side BC.
It will divide the side BC in two equal parts.
i.e. BD = DC = 
Using Pythagorean Theorem in
:

Side AD = 
Using Trigonometric ratio:


Putting the values of AD and BD:

<u>Exponential Grow Model</u>
The equation to model some time dependant event as an exponential is

Where Ao is the initial value, k is a constant and t is the time. With the value of Ao and k, we can compute the value of A for any time
We are required to find the time when the population being modeled doubles from Ao to 2 Ao. We need to solve the equation

Simplifying by Ao

Taking logarithms in both sides

By properties of logarithms and since lne=1

Solving for t

Hence proven

Answer:
6
Step-by-step explanation:
Maybe you want a suitable common denominator for 2/3 and 1/6. If so, you can observe that 3 is a factor of 6, so 6 is a suitable common denominator.
2/3 = (2/3)·(2/2) = (2·2)/(3·2) = 4/6
The equivalents, 4/6 and 1/6, share a common denominator of 6.
