Ответ:
Define unit vectors as follows:
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
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.
The magnitude of (a-b) is 97.58 or 69√2.
The direction is 45° north of west.
Ответ:
y = x^2 - 5x + 4
y = x^2 - 4x - x + 4
y = x ( x - 4 ) - ( x - 4 )
y = ( x - 4 ) ( x - 1 )
ANSWER:
Therefore, the answer is:
A. True.
Hope this helps! :)
Have a lovely day! <3
