So the equation you would have to set up would be: (3m)+(2m-5)=90.

If your wondering where I got the 90 from I got it because the question states it is a right angle.

So now you combine like terms:

3m+2m=5m

Which leaves you:

5m+(-5)=90 or 5m-5=90

Then you do the opposite operation by changing subtraction to addition:

5m-5=90
+5
(Don’t forget your do the same on the other side)

5m-5=90
+5 +5
—————-

And then your left with:

5m=95

Then you divide by 5 on both sides by creating a fraction:

5m=95
—- —-
5 5

And you get your answer:

m=19

Use the Taylor series you just found for sinc(x) to find the Taylor series for f(x) = (integral from 0 to x) of sinc(t)dt based

Marina CMI [18]

In this question (brainly.com/question/12792658) I derived the Taylor series for $\mathrm{sinc}\,x$ about $x=0$ :

$\mathrm{sinc}\,x=\displaystyle\sum_{n=0}^\infty\frac{(-1)^nx^{2n}}{(2n+1)!}$

Then the Taylor series for

$f(x)=\displaystyle\int_0^x\mathrm{sinc}\,t\,\mathrm dt$

is obtained by integrating the series above:

$f(x)=\displaystyle\int\sum_{n=0}^\infty\frac{(-1)^nx^{2n}}{(2n+1)!}\,\mathrm dx=C+\sum_{n=0}^\infty\frac{(-1)^nx^{2n+1}}{(2n+1)^2(2n)!}$

We have $f(0)=0$ , so $C=0$ and so

$f(x)=\displaystyle\sum_{n=0}^\infty\frac{(-1)^nx^{2n+1}}{(2n+1)^2(2n)!}$

which converges by the ratio test if the following limit is less than 1:

$\displaystyle\lim_{n\to\infty}\left|\frac{\frac{(-1)^{n+1}x^{2n+3}}{(2n+3)^2(2n+2)!}}{\frac{(-1)^nx^{2n+1}}{(2n+1)^2(2n)!}}\right|=|x^2|\lim_{n\to\infty}\frac{(2n+1)^2(2n)!}{(2n+3)^2(2n+2)!}$

Like in the linked problem, the limit is 0 so the series for $f(x)$ converges everywhere.

The second and fourth selections represent a translation to the right by 1 unit. The fourth selection represents a vertical reflection about the x-axis. The picture shown can be considered to be a right translation and a vertical reflection of $\sqrt[3]{x}$ .

The 4th selection is appropriate.
