-16/27 is your answer
-31/9 x 1/6
-16/9 x 1/3
= 16/27
1) We can find the magnitude of a vector(a.k.a. the norm) of a vector and the direction, by making use of the following formulas:
2) In this question, the magnitude and the direction of that vector have been given to us. So, let's do the other way around to identify which one has this magnitude and direction.
Note that since we want a positive value, we need to add 360 degrees.
Answer:
sinC =
Step-by-step explanation:
We require to find the side DE before finding sinC
Using Pythagoras' identity in the right triangle
DE² + CE² = CD²
DE² + 5² = ( )²
DE² + 25 = 41 ( subtract 25 from both sides )
DE² = 16 ( take the square root of both sides )
DE = = 4 , then
sinC = = = , rationalise the denominator
sinC = × =
Answer:
2
Step-by-step explanation:
11 and 23
That equation doesn't work because you're saying 3-3 and that does not equal 6
