I do know what this is but you are missing a big bit of info , the best way to solve is to use the grit link because you can type it in.
Answer:
3240 degrees.
Step-by-step explanation:
Here (as you said), this 20-gon is convex. In the image below, that is #1. One interior angle is 162 degrees. Simply multiply that by 20 to get 3240 degrees as the sum.
No;
it is exponentially always increasing
Answer:
A $2000
Step-by-step explanation:
Let x be the least amount of money the club has to make to get $600 then...
30%x=600
We can convert 30% to a fraction. Any percentage is that number percent over hundred:

Simplify the fraction by dividing it by 10/10. Notice we can only do this since 10/10 is equivalent to 1, so in a sense we are dividing the fraction by 1:

Multiply 10 to both sides

Divide both sides by 3

The club would have to make at least $2000
Just substitute it into the gradient formula which is: y2 - y1 / x2 - x1. So 2-3/2-9 = -1/-7 = 1/7
