<em>x³ + x²y - xy² - y³</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>(x − y)(x² + 2xy + y²) =</em>
<em>= x(x² + 2xy + y²) - y(x² + 2xy + y²)</em>
<em>= x³ + 2x²y + xy² - x²y - 2xy² - y³</em>
<em>= x³ + x²y - xy² - y³</em>
<em>Good luck !</em>
Three and six tenths
Hope I helped!
Answer:
Please check the explanation.
Step-by-step explanation:
Given that
|v|=38
Ф = 120°
<u>Finding the horizontal component</u>
The horizontal component can be obtained using the formula
Vx = |v| cos Ф
= 38 cos 120°
= 38 (-0.5)
= -19
Thus, the horizontal component is:
Vx = -19
<u>Finding the vertical component</u>
The vertical component can be obtained using the formula
Vy = |v| sin Ф
= 38 sin 120°
= 38 (0.86)
= 32.68
Thus, the vertical component is:
Vy = -19
- A vector 'v' with magnitude |v| and direction Ф can be written as:
v = |v| cos Ф i + |v| sin Ф j
As
|v|=38
Ф = 120°
Thus, the vector is
v = 38 cos 120° i + 38 sin 120° j
or
v = -19 i + 32.68 j
