Answer:
125.99/100 X 108 = 136.0692
round to 2 dp = $136.07
Answer:
Length of B is 7.4833
Step-by-step explanation:
The vector sum of A and B vectors in 2D is

And its magnitude is:

Where




Using the properties of the sum of two angles in the sin and cosine:


Sustituying in the magnitud of the sum




Solving for B


Sustituying the value of the magnitud of A


The initial is 21 and the rate of change is the slope so it would be 6
1. sector. If you draw it out, it is like a slice of a pie. When you think sector, think section.
2. A 60 degree sector is 1/6 of a circle which is 360 degrees. So the area is 1/6 * 42 = 7, so B
3. area = pi * r^2 = 3.14 * 3^2 = 28.27, which is closest to A
