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: 8x2+13y
Step by step: x+9y+8x2-x+4y
x+13y+8x2-x (x-x cancels x)
(put everything in order) 8x2+13y
Answer:
See below
Step-by-step explanation:
1)
Once
, it is an irrational number because is irrational.
, it is an irrational number because is irrational
2) In order to compare those two fractions put them in the same denominator.
Once
So,
This is because, when two fractions have the same denominator, the larger number between them is the fraction with the lowest numerator.
Both are rational numbers because both denominator and numerator are integers.
Answer:
We have to questions here where we need to find the distance from the origin to each given point.
<h3>For (3,4).</h3>
The formula for distance is
Therefore, the value s that yields the coordinate (3,4) is 5 units.
<h3>For (9,1).</h3>
Therefore, the value s that yields the coordinate (9,1) is 9.05 units, approximately.
