Answer:

43.96

Step-by-step explanation:

Circumference formula : 2πr

2π(7) = 14π

π is about 3.14

14(3.14) = 43.96

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 is 9/1 times 7/10

Grace [21]

To multiply two fractions:

-- Multiply their numerators; the product is the numerator of the new fraction.

9 x 7 = 63 ; the new fraction is (63) / (something)

-- Multiply their denominators; the product is the denominator of the new fraction.

1 x 10 = 10 ; the new fraction is <em>63/10</em> .

The product of the two original fractions is 63/10 , or <em>6.3</em> .
