Use a polar coordinate system to plot the point with the given polar coordinates. Then find another representation (r, theta) of this point in which:

(a) rgreater than0, 2piless thanthetaless than4pi.

(b) rless than0, piless thanthetaless than3pi.

(c) rgreater than0, minus2piless thanthetaless than0.

x=half

step-by-step explanation:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

answer: 1inch=7days  

12inch=12*7=84days

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:
