Find the total travel time: Depart 5:30pm MST Arrive 9:20pm CST.

1 answer:

8 0

2 hours and 50 minutes would be the answer. MST is one hour behind CST, so you would add an hour to 5:30 to basically make them the same time zone. Then you find the time between 9:20 and 6:30 to get 2 hours and 50 minutes.

C xy2 ds, c is the right half of the circle x2 y2 = 4 oriented counterclockwise

Kryger [21]

Parameterize the contour by

$C:\mathbf r(t)=(2\cos t,2\sin t)\implies \dfrac{\mathrm d\mathbf r}{\mathrm dt}=(-2\sin t,2\cos t)$
$\implies\mathrm dS=\sqrt{\left(\dfrac{\mathrm dx}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy}{\mathrm dt}\right)^2}\,\mathrm dt=2$

where $-\dfrac\pi2\le t\le\dfrac\pi2$ . Then the line integral is given by

$\displaystyle\int_C xy^2\,\mathrm dS=2\int_{-\pi/2}^{\pi/2}(2\cos t)(2\sin t)^2\,\mathrm dt$
$=\displaystyle16\int_{-\pi/2}^{\pi/2}\cos t\sin^2t\,\mathrm dt=\dfrac{32}3$

The midpoint of AB is (3,2). If point is is located at(8,4) what are the coordinates of point B

Dmitry [639]

Step-by-step explanation:

8-3 = 5,

3-5 = -2 = the x coordinate of B

-2-4 =-6,

-2-6 =-8 = the y coordinate of B

(-2,-8) is the point B

A is 5 to the right of the midpoint, so B is 5 to the left of the midpoint

A is 6 up from the midpoint so B is 6 down from the midpoint
