Let f ( x , y )=5 x and let C be the segment of the parabola y = 2 x squared joining O( 0 , 0 ) and P( 1 , 2 ). a. Find a parame

taurus [48]

a. We can parameterize $C$ by

$x=t$

$y=2t^2$

with $0\le t\le1$ . Then

$\displaystyle\int_C5x\,\mathrm dS=\int_0^15t\sqrt{1+16t^2}\,\mathrm dt=\dfrac5{48}(17^{3/2}-1)$

b. We can parameterize the opposite direction by instead setting

$x=1-t$

$y=2(1-t)^2$

with $0\le t\le 1$ . Then

$\displaystyle\int_C5x\,\mathrm dS=\int_0^15(1-t)\sqrt{1+16(1-t)^2}\,\mathrm dt=-\int_1^05u\sqrt{1+16u^2}\,\mathrm dt=\int_0^15u\sqrt{1+16u^2}\,\mathrm du$

which gives the same value as in part (a).

William is planning to buy a guitar for $35.95. The sales tax rate is 8.25%. He wants to be sure he has enough money. How much w

LekaFEV [45]

If you would like to know how much will the guitar cost, including the sales tax, you can calculate this using the following steps:

8.25% of $35.95 = 8.25% * 35.95 = 8.25/100 * 35.95 = $2.97

$35.95 + $2.97 = $38.92

The correct result would be $38.92.
