The square root of -36 is 6i
Answer:
Option (3)
Step-by-step explanation:
w =
Since, cos(225) = cos(180 + 45)
= -cos(45) [Since, cos(180 + θ) = -cosθ]
= -
sin(225) = sin(180 + 45)
= -sin(45)
= -
Therefore, w =
=
=
z = 1[cos(60) + i(sin(60)]
=
=
Now (w + z) =
=
=
=
Therefore, Option (3) will be the correct option.
Answer:
252 Cheese Bugers were sold on Thursday
Step-by-step explanation:
378 divided by 3=126
126+126= number of hamburgers
126= number of chese bugers
126+126=252
8 is a factor of 16, so you would multiply the numerator and denominator of 5/8 and 6/8 by 2. this would be 10/16 and 12/8. add all of the numbers together = 10+12+4 which equals 26. it’d be 26/16 or 1 and 10/16.
