Convert the line integral to an ordinary integral with respect to the parameter and evaluate it. modifyingbelow integral from no

vovangra [49]

Parameterize $C$ by

$\vec r(t)=(1-t)(0,0,0)+t(1,3,6)=(t,3t,6t)$

with $0\le t\le1$ . Then the line integral is

$\displaystyle\int_Cxyz\,\mathrm dS=\int_0^1x(t)y(t)z(t)\left\|\frac{\mathrm d\vec r}{\mathrm dt}\right\|\,\mathrm dt$

$=\displaystyle18\sqrt{91}\int_0^1t^3\,\mathrm dt=\boxed{\frac{9\sqrt{91}}2}$

Answer:

2 should be distributed as 2y + 16; y = 8

Step-by-step explanation:

We have to distribute 2, then:

Now we have to sum (-2y) in both sides of the equation:

Finally we have to divide both sides of the equation in 2:

Then the answer is 2 should be distributed as 2y + 16; y = 8

Hope this helps.

lesantik [10]

Answer:

The difference between the number of pages that Darla and Juan read are <u>VI pages</u>.

Step-by-step explanation:

Given:

Darla told her teacher that she had read XLV pages in her library book.

Juan said that he had read XXXIX pages.

Now, to get the difference between the number of pages that Darla read and Juan read.

As, we see the number of pages are in roman numeral symbols.

So, we convert them in numbers first to calculate:

Darla read = XLV pages.

Darla read = 45 pages.

Now,

Juan read = XXXIX pages.

Juan read = 39 pages.

So, to get the difference between the number of pages by subtracting:

$45-39=6$

<em>Thus, the difference between the number of pages = 6 pages.</em>

Now, converting it into roman numerals:

6 pages = VI pages.

Therefore, the difference between the number of pages that Darla and Juan read are VI pages.
