Answer:
miles did she drive each day.
Step-by-step explanation:
As per the statement: Melanie's trip was 500 miles long. She drove the same number of miles each day for 3 days.
⇒ for 3 days she drove the number of miles 500 miles long
then;
for 1 days = miles
Convert into mixed number .
Mixed number is made up of a whole number and a fraction number.
Therefore, miles did she drive each day.
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.
