This is the same as the other one except no division at the end:

$(x-8)^2=7$

Taking square roots, we need to remember the plus or minus:

$x-8 = \pm \sqrt 7$

$x = 8 \pm \sqrt 7$

That's a positive 8 and either sign on the square root.

EXAMPLE 2 Prove that 9ex is equal to the sum of its Maclaurin series. SOLUTION If f(x) = 9ex, then f (n + 1)(x) = for all n. If

Answer:

To Prove: $9e^x$ is equal to the sum of its Maclaurin series.

Step-by-step explanation:

If $f(x) = 9e^x$ , then $f ^{(n + 1)(x)} =9e^x$ for all n. If d is any positive number and |x| ≤ d, then $|f^{(n + 1)(x)}| = 9e^x\leq 9e^d.$

So Taylor's Inequality, with a = 0 and M = $9e^d$ , says that $|R_n(x)| \leq \dfrac{9e^d}{(n+1)!} |x|^{n + 1} \:for\: |x| \leq d.$

Notice that the same constant $M = 9e^d$ works for every value of n.

But, since $lim_{n\to\infty}\dfrac{x^n}{n!} =0 $ for every real number x$$ ,

We have $lim_{n\to\infty} \dfrac{9e^d}{(n+1)!} |x|^{n + 1} =9e^d lim_{n\to\infty} \dfrac{|x|^{n + 1}}{(n+1)!} =0$

It follows from the Squeeze Theorem that $lim_{n\to\infty} |R_n(x)|=0$ and therefore $lim_{n\to\infty} R_n(x)=0$ for all values of x.

$THEOREM\\If f(x)=T_n(x)+R_n(x), $where $T_n $is the nth degree Taylor Polynomial of f at a and $ lim_{n\to\infty} R_n(x)=0 \: for \: |x-a|$

By this theorem above, $9e^x$ is equal to the sum of its Maclaurin series, that is,

$9e^x=\sum_{n=0}^{\infty}\frac{9x^n}{n!}$ for all x.

Convert from $0.20 dollars to cents

Arada [10]

Since 100 cents = $1

Then to convert $20 to cents, all you have to do is multiply.

$20 × 100 cents

<em><u>=2000 cents. </u></em>

More examples to try:

Convert $0.10 dollars to cents.

$10 × 100 cents = 1000 cents.

Here is a guild for next time:

100 cents = $1
200 cents = $2
300 cents = $3
400 cents = $4
___ cents = $__

So.....now you can fill in the blanks by yourself. Tell me the answer if possible! :D

~Hope this helped!~
