Answer:
Area of nonagon = 1044.6 square millimetres.
Step-by-step explanation:
Let side of the nonagon is a
Given:
The perimeter of nonagon is 117 millimetres
Put the perimeter value in above equation
So the side of the nonagon is 13
The area of the nonagon is .
where a is side of the nonagon.
Put value of side in above equation
Therefore, the area of the nonagon is 1044.6 square millimetre.
Four nickels,
because 1 dime=10¢ and so 21 x .10 = 2.10 and 1 nickel=5¢ so .05 x 4 = .20
2.10 + .20 = 2.30
I’m not sure if the explaining made sense but it’s 4 nickels :)
To solve this problem you must apply the proccedure shown below;
1. You have the following exponential equation given in the problem above:
3.2+e^(6x)=54.2
2. You must solve for e, as following:
e^(6x)=54.2-3-2
e^(6x)=51
3. By applying ln, you obtain:
ln(e)^(6x)=ln(51)
6x=ln(51)
x=ln(51)/6
x=0.65
Therefore, the answer is: x=0.65
