Convert the complex number from rectangular form to polar form. show all work for full credit. z= -14 + 8i explain!

z = 2 sqrt(65) (cos( -.52) +i sin (-.52) )

Step-by-step explanation:

to find the radius = sqrt(a^2 +b^2)

r = sqrt((-14^2 +8^2))

r = sqrt( 196+ 64)

r = sqrt (260)

r = sqrt(4*65)

r = 2sqrt(65)

theta = arctan (b/a)

theta = arctan (8/-14)

theta = arctan (-4/7)

theta =-.52 radians

z = r (cos theta + i sin theta)

z = 2 sqrt(65) (cos( -.52) +i sin (-.52) )

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
