If lim x-> infinity ((x^2)/(x+1)-ax-b)=0 find the value of a and b

MAXImum [283]

We have

$\dfrac{x^2}{x+1}=\dfrac{(x+1)^2-2(x+1)+1}{x+1}=(x+1)-2+\dfrac1{x+1}=x-1+\dfrac1{x+1}$

$\displaystyle\lim_{x\to\infty}\left(\frac{x^2}{x+1}-ax-b\right)=\lim_{x\to\infty}\left(x-1+\frac1{x+1}-ax-b\right)=0$

The rational term vanishes as x gets arbitrarily large, so we can ignore that term, leaving us with

$\displaystyle\lim_{x\to\infty}\left((1-a)x-(1+b)\right)=0$

and this happens if a = 1 and b = -1.

To confirm, we have

$\displaystyle\lim_{x\to\infty}\left(\frac{x^2}{x+1}-x+1\right)=\lim_{x\to\infty}\frac{x^2-(x-1)(x+1)}{x+1}=\lim_{x\to\infty}\frac1{x+1}=0$

as required.

Kaylis [27]

The probabilities can be calculated using an online calculator or tables, depending on which is more readily available.

QUESTION A

$P(Z>1.48)$

Using calculators, the probability will be:

$P(Z\gt1.48)=0.069$

QUESTION B

$P(Z\leq1.94)$

Using calculators, the probability will be:

$P(Z\leq1.94)=0.974$

QUESTION C

$P(-0.76Using calculators, the probability will be:[tex]P(-0.76\lt Z\lt2.05)=0.756$

Estimate. Then record the product. 640×3=

ExtremeBDS [4]

You could estimate by doing 600x3=1800
(becasuse of the 0's in 600 it is easier to do 6*3=18 and then add two 0's to the end 1800)
then you simply multiple 640x3=1920
