∫c x sin y ds, C is the line segment from (0, 1) to (3, 5)

Mnenie [13.5K]

Parameterize the line segment $C$ by

$\mathbf r(t)=\langle x(t),y(t)\rangle=(1-t)\langle0,1\rangle+t\langle3,5\rangle=\langle3t,1+4t\rangle$

where $t\in[0,1]$ . Then

$\mathrm ds=\|\mathbf r'(t)\|\,\mathrm dt$
$\mathrm ds=\|\langle3,4\rangle\|\,\mathrm dt$
$\mathrm ds=5\,\mathrm dt$

So the integral is

$\displaystyle\int_Cx\sin y\,\mathrm ds=5\int_0^1x(t)\sin y(t)\,\mathrm dt$
$=\displaystyle5\int_0^13t\sin(1+4t)\,\mathrm dt$
$=\dfrac{15}{16}(\sin5-\sin-4\cos5)\approx-2.7516$

10 = 43 – |17p + 12|

Kaylis [27]

10=43–|17p+12|

You won't use the absolute sign here. Since you cannot add variable to number AND there are no negatives.

10=43–|17p+12|

10=43–17p+12

Add 12 to 43.

10=43–17p+12

10=55-17p

Add 17p on both sides.

10=55-17p

17p+10=55

Subtract 10 from both sides.

17p+10=55

17p=45.

Therefore, the answer is p=2.64705882353.
