Answer: $QR=4.04$

Step-by-step explanation:

For this exercise you must use the followinG Trigonometric Identity:

$tan\alpha=\frac{opposite}{adjacent}$

In this case, given the right triangle PQR, you can identify that:

$\alpha=60\°\\opposite=PR=7.0\\adjacent=QR$

Then, the next step is to substitute those values into $tan\alpha=\frac{opposite}{adjacent}$ :

$tan(60\°)=\frac{7.0}{QR}$

And the final step is to solve for "QR" in order to find its value.

So you get that this is:

$(QR)(tan(60\°))=7.0\\\\QR=\frac{7.0}{tan(60\°)}\\\\QR=4.04$

A plane curve is defined by the following paramedic equation:

vazorg [7]

X = 2 cos t and y = sin t \\ For the given parametric equations the common between them is t \\ So. The parameter is t. \\ The general coordinates for the points of the curve will be (x,y) \\ So, the coordinates will be ( 2 cos t , sin t )
The correct answer is option C
C) the parameter is t and the curve contains the set of points (2cos(t),sin(t))

Solve linear system using substitution y=6-2x 7x-y=3

Naddik [55]

$\left \{ {{y=6-2x} \atop {7x-y=3}} \right. \\\\substitute\ first\ equation\ into\ the\ second\\\\
7x-(6-2x)=3\\\\
7x-6+2x=3\\\\
9x-6=3\ \ \ | add\ 6\\\\
9x=9\ \ \ | divide\ by\ 9\\\\
x=1\\\\
y=6-2*1=6-2=4$
