Answer: cos(C)

Step-by-step explanation: Use SohCahToa. Sin(A) is opposite over hypotenuse. The opposite is line BC. Use angle C. To get line BC, you will need the adjacent, and also the hypotenuse. Cos will get you this. Therefore, your answer is Cos(C).

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.

What are the values of x in the equation 4x^2+4x-3=0

ludmilkaskok [199]

I have an answer and an explanation!

ANSWER: $X=\frac{1}{2} (or) x= \frac{-3}{2}$

Explanation:

{Let's solve your equation step-by-step.}
 $4 x^{2} +4x-3=0$

{Step 1: Factor left side of equation.}
 $(2x-1)(2x+3)=0$

{Step 2: Set factors equal to 0.}
 $2x-1=0 (or) 2x+3=0$
