Answer:

Perry's claim is correct while Karina is incorrect

Step-by-step explanation:

Question is incomplete (See Attachment)

First, we need to determine the area covered by Karina and Perry

For Karina, there are 9 square boxes each of which has an area of 1 unit sq

So:

Karina = 9 * 1\ unit^2

Karina = 9\ unit^2

For Perry:

There are 18 square boxes, each of which has an area of 1 unit sq.

So:

Perry = 18 * 1\ unit^2

Perry = 18\ unit^2

Comparing both areas, we can conclude that <em>Perry's claim is correct while Karina is incorrect</em>

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}

I really need help this is a matter or passing or failing and I am counting on you for help!
coldgirl [10]

Answer:

B

Step-by-step explanation:

In order for something to have infinite solutions, both sides need to be equal to each other.

Example:

3x + 7y = 7y + 3x

That has infinite solutions

3x + 7y = 7x + 3y

That is not equal to each other because the variables are different.

Hope I helped :)
