Answer:

See below directions.

Step-by-step explanation:

The condition -2\pi means you can get to the point by rotating no more than one revolution in either the positive or negative direction.

See the attached image to see the point \left(3,\,-\frac{3\pi}{4}\right).  Think about how you get to that point:  start at the origin, go right (along the positive x-axis) 3 units, then turn in the negative direction (to your right!) through an angle of \frac{3\pi}{4}.

Now, go again, starting at the origin, only this time, go 3 units right, then turn through an angle of -\frac{3\pi}{4}+2\pi=\frac{5\pi}{4}.  In other words, you turn one whole revolution <u>in addition</u> to the -\frac{3\pi}{4} angle.  Your point can now be described by \left(3,\,\frac{5\pi}{4}\right).

Another description can be found by rotating in the opposite direction, so an angle of \frac{3\pi}{4} and <u>backing up</u> 3 units -- specify a "radius" of -3.  The point is then \left(-3,\,\frac{3\pi}{4}\right).

You can also try subtracting one revolution (2\pi) from the angle, but be careful not to let the angle go outside the interval  -2\pi.

The changes you can try are:  

add 2\pi to the angle, leave <em>r</em> alone

subtract 2\pi to the angle, leave <em>r</em> alone

add/subtract \pi (half a revolution) to the angle, make <em>r</em> the <u>opposite</u><em><u>.</u></em>

HELP ME PLZ answer question below
Ronch [10]

Answer:

11. -2

12. +0.5

Step-by-step explanation:

11. as x increases by 1, y decreases by 2, -2/1 = -2 the ROC is -2 (rate of change)

12. as x increases by 2, y increases by 1, 1/2 = 0.5, ROC is +0.5

Find the center of the circle whose equation is x² + y² = 4.
Varvara68 [4.7K]

Answer:

The center of circle is (0,0)

Step-by-step explanation:

We need to find the center of the circle of the equation x^{2}+y^{2}=4

Since, the general equation of circle is (x-h)^{2}+(y-k)^{2} = r^{2}

Where (h,k) is center of circle and r is radius.

Re-write the circle equation is x^{2}+y^{2}=4 as,

x^{2}+y^{2}=2^{2}

Compare x^{2}+y^{2}=2^{2} with (x-h)^{2}+(y-k)^{2} = r^{2}

so, (x-0)^{2}+(y-0)^{2} = 2^{2}

Hence, the center of circle is (0,0)
