3)
=w^12z^18
answer
C. w^12z^18
4)
= 4x^6
answer
B. 4x^6
We have that
the measure of angle ∅=7*pi/6
the measure of its reference angle is?
remember that pi=180°
then
7*pi/6=7*180/6=210°------------> III Quadrant
Part A) its reference angle is 210°-180°=30°
Part B) sin(30°)=-0.5--------> negative because belongs III quadrant
Answer:
465.988 mph
Step-by-step explanation:
The two speed vectors form two sides of a triangle. Their included angle is 45°, so the law of cosines can be used to find the resultant magnitude x.
x^2 = 500^2 +50^2 -2·500·50·cos(45°) ≈ 217,144.66
x ≈ √217,144.66 ≈ 465.988 . . . . miles per hour
_____
You may find you need to round the answer to the nearest whole number.
The answers are (2 1/2, 10) and (3, 12)
//I just took the test and these were the answers
17/8 -11/3
51/24-88/24
-37/24 simplified is -1 13/24
