The polar coordinates of a point are 3π 4 and 7.00 m. What are its Cartesian coordinates (in m)? (x, y) = 6.06,−3.5 m

a)

b)

Step-by-step explanation:

Polar coordinates are represented as: , where 'r' is the length (or magnitude) of the line, and '' is the angle measured from the positive x-axis.

in our case:

to covert the polar to cartesian:

we can plug in our values:

the Cartesian coordinates are:

(b) to convert (x,y) = (6.06,-3.5)

we'll use the pythagoras theorem to find 'r'

the angle can be found by:

to convert radians to degrees:

writing in polar coordinates:

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
