Answer:
Step-by-step explanation:
To try to solve these problems, you could plug 'n play. If all the blanks are addition, you/ll be > 24
If all the blanks are subtraction, it will be < 0
Multiplication doesn't work for all of them.
I did notice that 15 + 9 = 24, 5*6 = 30, and you get back to 15 if you subtract 15 after multiplying 5 and 6
5(3)-(-3)
15- (-3)
15+3 = 18
Refer to the figure below.
Define unit vectors as follows:
in the eastern direction
in the northern direction
Given:
Vectors a and b point due west and south respectively. Therefore
Part (a)
The magnitude is
|-69(√[1² + 1²])| = 69√2 = 97.58.
The direction relative to west is
θ = tan⁻¹ (b/a) = tan⁻¹ 1 = 45° south of west
Answer:
The magnitude of (a + b) is 97.58 or 69√2.
The direction is 45° south of west.
Part (b).
The magnitude is
|69(√(1+1)| = 69√2 = 97.58.
The direction relative to west is
tan⁻¹ (b/a) = 45° north of west.
Answer:
The magnitude of (a-b) is 97.58 or 69√2.
The direction is 45° north of west.
