5. Two vertices of a triangle lie at (4, 0) and (8, 0). The perimeter of the triangle is 12 units. What are all the possible loc

ations of the third vertex? How do you know you have found them all? Can you determine which of these vertices will produce a triangle with the largest area?

Answer: x=8 and y=±3

Step-by-step explanation:

Perimeter= Sum of length of sides

Let A= (4,0)

B= (8,0)

C= (x,y)

So

AB+BC+CA = 12

\sqrt{(8-4)^{2} -(0-0)^{2} } + \sqrt{(x-8)^{2}+(y-0)^{2}  }  + \sqrt{(4-x)^2+(0-y)^{2} }= 12

Solving it, the possible outcomes comes out to be

x= 4, y=±3

x=8, y=±3

x=2, y=0

x=10, y=0

For the largest area, we would use

x=8 and y=±3

Part 1)  \displaystyle \frac{1}{n^2} or 1/(n^2) goes in the box.

Part 2)  The series <u>converges</u>

======================================================

Work Shown:

\displaystyle L = \lim_{n\to \infty} \frac{a_n}{b_n}\\\\\\\displaystyle L = \lim_{n\to \infty} \frac{\frac{n+3}{n^3-5n+8}}{\frac{1}{n^2}}\\\\\\\displaystyle L = \lim_{n\to \infty} \frac{n+3}{n^3-5n+8}\times\frac{n^2}{1}\\\\\\\displaystyle L = \lim_{n\to \infty} \frac{n^3+3n^2}{n^3-5n+8}\\\\\\

\displaystyle L = \lim_{n\to \infty} \frac{\frac{n^3}{n^3}+\frac{3n^2}{n^3}}{\frac{n^3}{n^3}-\frac{5n}{n^3}+\frac{8}{n^3}}\\\\\\\displaystyle L = \lim_{n\to \infty} \frac{1+\frac{3}{n}}{1-\frac{5}{n^2}+\frac{8}{n^3}}\\\\\\\displaystyle L = \frac{1+0}{1-0+0}\\\\\\\displaystyle L = 1\\\\\\

Because L is finite and positive, i.e. 0 < L < \infty, this means that the original series given and the series  

\displaystyle \sum_{n=1}^{\infty} \frac{1}{n^2}  

either converge together or diverge together due to the Limit Comparison Test.

But the simpler series is known to converge (p-series test).

Therefore, the original series converges as well.

The two series likely don't converge to the same value, but they both converge nonetheless.
