Answer:

None of these

Step-by-step explanation:

To convert the parametric curve into Cartesian form,
rewrite the equation for $x$ to make $\sin t$ the subject:

$x=2\sin t$

$\implies \sin t=\dfrac{x}{2}$

Substitute this into the given equation for $y$ :

$\begin{aligned}y & =3 \sin t\\\implies y & = 3 \left(\dfrac{x}{2}\right)\\y& = \dfrac{3}{2}x\end{aligned}$

Therefore, the Cartesian form of the parametric curve is:

$y=\dfrac{3}{2}x$

$x^2+y^2=6 \quad \textsf{is the equation of a circle}$

$\textsf{with center (0, 0) and radius }\sf \sqrt{6}$

$3x^2+2y^2=1 \quad \textsf{is the equation of a vertical ellipse}$

$\textsf{with center (0, 0), co-vertex }\sf \dfrac{\sqrt{3}}{3}, \textsf{ and vertex }\dfrac{\sqrt{2}}{2}$

14. A plane traveled from California and back. It took one hour longer on the way out than it did on the way back. The plane's a

kow [346]

Answer:

C. 7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

distance = speed × time

300t = 350(t -1)

300t = 350t -350 . . . . eliminate parentheses

350 = 50t . . . . . . . . . . add 350-300t

7 = t . . . . . . divide by 50

The trip out took 7 hours.
