Answer: 135°
Step-by-step explanation: In this problem, we're asked to find the measure of each interior angle of a regular octagon.
So let's use our formula for finding the measure of
each interior angle of a regular octagon which is .
In this formula, <em>n</em> represents the
number of sides of the polygon.
Remember that an octagon is a polygon that has 8 sides
so we plug a 8 in for <em>n</em> and we have .
Simplifying across the top, (8 - 2) is 6so we have .
180(6) is 1,080 so we have and
1,080 divided by 8 gives us 135.
So the measure of each interior angle of a regular octagon is 135°.

b) 394 thousand = 394,000 people will be following the website in 2016
Step-by-step explanation:
Exponential equation for an amount:
The exponential equation for an amount after t years has the following format:
In which y(0) is the initial value and r is the growth rate, as a decimal.
A social media website had 350,000 followers in 2010. The number y of followers increases by 2% each year.
This means that:
a. Write an exponential growth function that represents the number of followers t years after 2010
In thousands:
b. How many people will be following the website in 2016?
2016 is 6 years after 2010, so this is y(6).
Rounding to the nearest thousand:
394 thousand = 394,000 people will be following the website in 2016
