Answer:
-1 > -3
Step-by-step explanation:
In the first play, Mark's favorite team lost 3 yards. This mean a negative representation as is a lost: -3.
In the second play, Mark's favorite team lost 1 yards. This mean a negative representation as is a lost: -1.
When locating -3 and -1 in the number line, all the numbers to the right of the number -3 are greater than this number.
From this we can say that the inequality statement is: -1 > -3.
This means that -1 is greater than -3.

Answer:
-8i
Step-by-step explanation:
To multiply numbers is polar form
z1 = r1 ( cos theta 1 + i sin theta 1)
z2 = r2 ( cos theta 2 + i sin theta 2)
z1*z2 = r1*r2 (cos (theta1+theta2) + i sin (theta1+theta2)
z1 = 2(cos 70° + i sin 70°)
z2 = 4(cos 200+ i sin 200)
z1z2 = 2*4 (cos (70+200) + i sin (70+200)
z1z2 = 8 (cos(270) + i sin (270))
= 8 (0 + i (-1))
=-8i
Raising a number to the 1/2 power means taking its square root.
