So, on Monday he ate 1/7, that means from a whole 7/7, take away 1/7, the leftover was 6/7 then.

on Tuesday, he ate 1/6 of the leftover, namely, 1/6 of 6/7.

now, how much is 1/6 of 6/7?  well, is just their product,   \bf \cfrac{1}{6}\cdot \cfrac{6}{7}\implies \cfrac{1}{7}

now, so he really ate 1/7 of the whole thing on Tuesday, there were 6/7 remaining, how much is 6/7 - 1/7?  yeap, you guessed it, 5/7.

\lim _{x\to 0}\left(\frac{2x\ln \left(1+3x\right)+\sin \left(x\right)\tan \left(3x\right)-2x^3}{1-\cos \left(3x\right)}\right)
Vinvika [58]

\displaystyle \lim_{x\to 0}\left(\frac{2x\ln \left(1+3x\right)+\sin \left(x\right)\tan \left(3x\right)-2x^3}{1-\cos \left(3x\right)}\right)

Both the numerator and denominator approach 0, so this is a candidate for applying L'Hopital's rule. Doing so gives

\displaystyle \lim_{x\to 0}\left(2\ln(1+3x)+\dfrac{6x}{1+3x}+\cos(x)\tan(3x)+3\sin(x)\sec^2(x)-6x^2}{3\sin(3x)}\right)

This again gives an indeterminate form 0/0, but no need to use L'Hopital's rule again just yet. Split up the limit as

\displaystyle \lim_{x\to0}\frac{2\ln(1+3x)}{3\sin(3x)} + \lim_{x\to0}\frac{6x}{3(1+3x)\sin(3x)} \\\\ + \lim_{x\to0}\frac{\cos(x)\tan(3x)}{3\sin(3x)} + \lim_{x\to0}\frac{3\sin(x)\sec^2(x)}{3\sin(3x)} \\\\ - \lim_{x\to0}\frac{6x^2}{3\sin(3x)}

Now recall two well-known limits:

\displaystyle \lim_{x\to0}\frac{\sin(ax)}{ax}=1\text{ if }a\neq0 \\\\ \lim_{x\to0}\frac{\ln(1+ax)}{ax}=1\text{ if }a\neq0

Compute each remaining limit:

\displaystyle \lim_{x\to0}\frac{2\ln(1+3x)}{3\sin(3x)} = \frac23 \times \lim_{x\to0}\frac{\ln(1+3x)}{3x} \times \lim_{x\to0}\frac{3x}{\sin(3x)} = \frac23

\displaystyle \lim_{x\to0}\frac{6x}{3(1+3x)\sin(3x)} = \frac23 \times \lim_{x\to0}\frac{3x}{\sin(3x)} \times \lim_{x\to0}\frac{1}{1+3x} = \frac23

\displaystyle \lim_{x\to0}\frac{\cos(x)\tan(3x)}{3\sin(3x)} = \frac13 \times \lim_{x\to0}\frac{\cos(x)}{\cos(3x)} = \frac13

\displaystyle \lim_{x\to0}\frac{3\sin(x)\sec^2(x)}{3\sin(3x)} = \frac13 \times \lim_{x\to0}\frac{\sin(x)}x \times \lim_{x\to0}\frac{3x}{\sin(3x)} \times \lim_{x\to0}\sec^2(x) = \frac13

\displaystyle \lim_{x\to0}\frac{6x^2}{3\sin(3x)} = \frac23 \times \lim_{x\to0}x \times \lim_{x\to0}\frac{3x}{\sin(3x)} \times \lim_{x\to0}x = 0

So, the original limit has a value of

2/3 + 2/3 + 1/3 + 1/3 - 0 = 2

Select the correct answer.
yulyashka [42]

Answer:

Option D is correct.

Volume=\frac{8}{27}\ cubic\ yard

Step-by-step explanation:

Let V be the volume of hay in each stack

Given:

Length of the each stack is \frac{2}{3}\ yard

And Jay stores hay in cubic stacks on his farm.

The volume of the cone is.

Volume\ of\ cone = (side)^{3}

Now, we substitute value of length of stack in above equation.

V=(\frac{2}{3})^{3}

V=\frac{2^{3}}{3^{3}}

V=\frac{8}{27}\ cubic\ yard

Therefore, the volume of hay in each stack is V=\frac{8}{27}\ cubic\ yard
