He reads 1/11 book in 2/5 hour.

A whole book is 11/11 of a book.

Multiply by 11.

He reads 11/11 book in 11 * 2/5 hour.

He reads 1 book in 22/5 hour.

22/5 hour = 4.4 hour = 4 hours and 24 minutes

Okay i need help finding y x 6 for y = 2/3 please help

aleksandr82 [10.1K]

First, you need to substitute y for 2/3:

2/3 • 6

Next, change 6 into a fraction and multiply straight across:

2/3 • 6/1
12/3

Finally, simplify it to its simplest form:

4
Your answer should be 4.
Hopefully that helped!

Evaluate the line integral, where c is the given curve. c y3 ds,

postnew [5]

Parameterizing $\mathcal C$ by

$\mathbf r(t)=(t^3,t)$

with $0\le t\le2$ , we have

$\mathrm ds=\|\mathbf r'(t)\|\,\mathrm dt=\sqrt{(3t^2)^2+1^2}\,\mathrm dt=\sqrt{9t^4+1}\,\mathrm dt$

So

$\displaystyle\int_{\mathcal C}y^3\,\mathrm ds=\int_{t=0}^{t=2}t^3\sqrt{9t^4+1}\,\mathrm dt$
$=\displaystyle\frac1{36}\int_0^236t^3\sqrt{9t^4+1}\,\mathrm dt$
$=\displaystyle\frac1{36}\int_{u=1}^{u=145}\sqrt u\,\mathrm du$
$=\dfrac{145^{3/2}-1}{54}$
