DENIUS [597]

To find the resultant vector you need to add the horizontal and vertical components of each individual vector.
Cosine for horizontal, Sine for vertical.
$v = \ \textless \ |v|cos \theta, |v| sin \theta\ \textgreater \$
Where |v| is magnitude or length of vector.
Lets look at first ranger station. First vector has magnitude 4.5 with angle of 90.
Next has magnitude of 8.1 with angle of 125.
$F_1 = \ \textless \ 4.5 cos(90)+8.1 cos(125) , 4.5 sin(90) + 8.1 sin(125) \ \textgreater \$
$F_1 = \ \textless \ -4.646, 11.135\ \textgreater \$
Find magnitude:
$|F_1| = \sqrt{((-4.646)^2+(11.135)^2} = 12.065$
Do the same with 2nd ranger station:
$F_2 = \ \textless \ 7.5 cos(20) + 5.3 cos(100), 7.5 sin(20) + 5.3 sin(100)\ \textgreater \$
$F_2 = \ \textless \ 6.127, 7.784\ \textgreater \$
$|F_2| = \sqrt{(6.127)^2 + (7.784)^2} = 9.9$

Therefore the 2nd ranger station is closest to starting point.

Which is the product of 4x^5-6x^4+4x^3-6x^2

Elanso [62]

Answer:

2 x^2 (2 x - 3) (x^2 + 1)

Step-by-step explanation:

Factor the following:

4 x^5 - 6 x^4 + 4 x^3 - 6 x^2

Factor 2 x^2 out of 4 x^5 - 6 x^4 + 4 x^3 - 6 x^2:

2 x^2 (2 x^3 - 3 x^2 + 2 x - 3)

Factor terms by grouping. 2 x^3 - 3 x^2 + 2 x - 3 = (2 x^3 - 3 x^2) + (2 x - 3) = x^2 (2 x - 3) + (2 x - 3):
