Please explain how they plugged the removable discontinuity in this question.

kondor19780726 [428]

In the limit

$\displaystyle \lim_{x\to c} f(x)$

we're interested in the value that $f(x)$ converges to as $x$ gets closer to $c$ . So in fact $x\neq c$ .

In the given example, $f(x)$ is factorized to reveal a common factor of $x-1$ in the numerator and denominator. We have $x\neq1$ if $x\to1$ , so $x-1\neq0$ so we can simplify

$\dfrac{x-1}{x-1} = 1$

and *remove* the discontinuity.

Then

$\displaystyle \lim_{x\to1} \frac{2(x-1)}{(x+1)(x-1)} = \lim_{x\to1} \frac2{x+1} = \frac2{1+1} = 1$

Linda had been collecting stamps for 5 weeks and had 25 stamps in her stamp book. Her book holds 64 stamps. She then began purch

coldgirl [10]

25 divided by 5 is 5 so she gave 5 stamps each week
64 divide by 3 would roughly be 12 weeks because otherwise it would be a renainder
12 add 5 equals 17 weeks
So it should take 17 weeks
hope this is right Please ask me if any doubts
Thank you Good Luck

Answer:

Entrance fee should be proportional to the number of visitors -- this means that if we divide entrance fee by number of visitors for each of them, we would have the same number.
