Acar moves along a horizontal road with constant velocity v0 = v0xiuntil it encounters a smooth inclined hill, which it climbs with constant velocity v1 = v1xi + v1yj as indicated in the figure. the period of time during which the car changes its velocity is δt. variablesv0x = 36 m/sv1x = 34 m/sv1y = 1.1 m/sδt = 1.4 spart a. give a vector expression for the average acceleration of the car during the given time period in terms of the variables in the problem and unit vectors i and j.

answer: it is 8

step-by-step explanation:

you know why its 8

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
