Answer:

AB = 2.5

Step-by-step explanation:

Given that,

AB is half of GJ.

$AB =\dfrac{GJ}{2}$

Also, AB = 2x+11 and GJ = 2x + 5

We need to find the value of AB.

ATQ,

$2x+11=\dfrac{2x+5}{2}\\\\\text{Cross multiplying both sides}\\\\4x+22=2x+5\\\\4x-2x = -22+5\\\\2x=-17\\\\x=-8.5$

So,

AB = x+11

= -8.5 + 11

= 2.5

Hence, the value of AB is 2.5.

To answer, we need to add the two fractions. However, to add them, they need to have a common denominator (the number on bottom). One easy way to do this is to multiply both so they are the same number. Use the opposite number! Then, you can add the numbers straight across. You will most likely need to simplify. If you have any further questions, let me know!

If f (n)(0) = (n + 1)! for n = 0, 1, 2, , find the taylor series at a=0 for f.

Pie

Given that $f^{(n)}(0)=(n+1)!$ , we have for $f(x)$ the Taylor series expansion about 0 as

$f(x)=\displaystyle\sum_{n=0}^\infty\frac{(n+1)!}{n!}x^n=\sum_{n=0}^\infty(n+1)x^n$

Replace $n+1$ with $n$ , so that the series is equivalent to

$f(x)=\displaystyle\sum_{n=1}^\infty nx^{n-1}$

and notice that

$\displaystyle\frac{\mathrm d}{\mathrm dx}\sum_{n=0}^\infty x^n=\sum_{n=1}^\infty nx^{n-1}$

Recall that for $|x|$ , we have

$\displaystyle\sum_{n=0}^\infty x^n=\frac1{1-x}$

which means

$f(x)=\displaystyle\sum_{n=1}^\infty nx^{n-1}=\frac{\mathrm d}{\mathrm dx}\frac1{1-x}$
$\implies f(x)=\dfrac1{(1-x)^2}$
