Approximate the horizontal and vertical components of the vector that is described. A child pulls a sled through the snow by exerting a force of 20 pounds at an angle of 40° with the horizontal.

Rule of finding the components of a vector a with magnitude r that makes an angle with positive x-axis:

Consider the vector that has radius r makes an angle O with positive x-axis. Then the component wise representation of the vector is

a=(x,y)

where,

x=rcos∅

y=rsin∅

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
