To solve this problem, first we need to derivate the given function, and then, evaluate the derivated function with x equal to 2.
The given function is:
It's a quotient, so, we need to use the following formula to derivate it:
Then, of the given function we have that:
So, derivating we have:
Hence,
Now, evaluating with x equal to 2, we have:
Therefore, the answer is:
Have a nice day!
First, I will solve for one triangle. To find the area of a triangle, you multiply width by height and half the product. So in other words 9 times 2, and that answer divided by 2. 9X2=18 and 18/2=9. Now multiply this triangle by 6, since the problem asks for 6 triangular pennants. 6X9=54 so 54.0ft² is your final answer.
