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∅

d is the only accurate one

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
