Answer:

Step-by-step explanation:

the perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width ) , then

P = 2(3 $\sqrt{15}$ ) + 2( $\sqrt{15}$ ) ← distribute both parenthesis )

= 6 $\sqrt{15}$ + 2 $\sqrt{15}$

= 8 $\sqrt{15}$

Find the values of x (if any) at which f(x)= x+1/x^2-1 is not continuous. If so, is the discontinuity removable?

Mkey [24]

$f(x)=\dfrac{x+1}{x^2-1}$ has two points of discontinuity at $x=\pm1$ , where $x^2-1=0$ .

We have

$\dfrac{x+1}{x^2-1}=\dfrac{x+1}{(x+1)(x-1)}$

so as long as $x\neq-1$ , we can cancel $x+1$ and be left with $\dfrac1{x-1}$ . Then as $x\to-1$ , we have

$\displaystyle\lim_{x\to-1}f(x)=\lim_{x\to-1}\frac1{x-1}=-\frac12$

The limit exists, so the discontinuity at -1 is removable (so definitely not C or D).

Meanwhile,

$\displaystyle\lim_{x\to1}f(x)=\lim_{x\to1}\frac1{x-1}$

does not exist, so the discontinuity at 1 is non-removable, making A the correct answer.
