Step-by-step explanation:

1/2 cannot be simplified, however you can solve this question by shading in the other half of the left square, and taking away a shade on the right one :)

Answer:

ok you can not simplify 1/2 but you can make it a higher proportion basically, one square can be one shaded purple of of the two rectangles and the other could be 4 different squares with two shaded purple

Eric needs 1/2 deck of playing cards for a magic trick. He only has 2/7 of a deck. What fraction of a deck does Eric still need?
tatyana61 [14]

Answer: Eric still needs \frac{3}{14} of a deck.

Step-by-step explanation:

You know that:

- Eric need 1/2 deck of playing cards.

- Eric has 2/7 of a deck.

Therefore, to find the fraction of a deck that Eric still needs, you must subtract 1/2 and 2/7:

- Find the least common multiple of the denominators:

2=2*1\\7=7*1

LCM=2*7*1=14

- Now, you can make the subtraction:

\frac{(7*1)-(2*2)}{14}=\frac{7-4}{14}=\frac{3}{14}

Therefore, he still needs \frac{3}{14} of a deck.

Helppp meeeeeeee plsssssss you got till nine

Answer:

3/20 of the cover page is text about endangered species.

Step-by-step explanation:

We know that 3/8th of the page is text, and 2/5ths of that text is about endangered species.

So all we have to do is find out how much 2/5ths of 3/8ths are, which can be done simply via fraction multiplication.

3/8 * 2/5 = ?

For multiplying fractions, we multiply the top parts together, and then the bottom parts together. So 3/ 8 * 2/5 would be equal to (3*2) / (8*5). This gives us 6 / 40 which can be simplified to 3/20.

So 3/20ths of the cover page is about endangered animals.

Find a power series representation of e^x sin(x)
liberstina [14]
The Taylor series is defined by:
f(x) = \sum \frac{f^n (a)}{n!} (x-a)^n

Let a = 0.
Then its just a matter of finding derivatives and determining how many terms is needed for the series.

Derivatives can be found using product rule:
f^n (x) = e^x g^{n-1} (x) + e^x g^n (x)  \\ g^0 (x) = sin x

Do this successively to n = 6.
f^1 (x) = e^x (sinx +cos x) \\ f^2 (x) = e^x (2cos x)  \\ f^3 (x) = e^x(2cos x - 2sin x)  \\ f^4 (x) = e^x (-4 sin x)  \\ f^5 (x) = e^x(-4sinx -4cos x) \\ f^6(x) = e^x(-8cos x)

Plug in x=0 and sub into taylor series:
e^x  sin x = x+x^2 +\frac{x^3}{3} -\frac{x^5}{30}-\frac{x^6}{90}...

If more terms are needed simply continue the recursive derivative formula and add to taylor series.
