Answer:
Work done is the product of distance and force, it is measured in joules.
Power is the rate of work done given by dividing the work done by time
Power (watts)= workdone (J)/ time (s)
= 50,000J/7 sec
= 7142.857 watts
Therefore, the power of the car during the race was 7142.857 watts
Step-by-step explanation:
It's how far a number is from 0.
( ex.) 6 is 6 away from 0 but so is -6; so the absolute value of 6 is 6 and the absolute value of -6 is 6. the symbol "|" is placed on either side to mean absolute value.
(ex.2) |-6| = 6. -|-6|= -6. |6|=6. and -|6|= -6.
if the negative sign is outside of the symbol then the number will always be negative but if there is no negative sign outside of the symbol it will always be positive, even if it looks lile this. |-6| it would still be positive.

Answer:
The equation of this line is y = -1/4x - 7/2
Step-by-step explanation:
To find this, we need to first look for the slope. Perpendicular slopes have opposite and reciprocal slopes. Since the original line has a slope of 4, this means the new one has a slope of -1/4.
Given that slope, we can find the equation by starting with the base form of point-slope form.
y - y1 = m(x - x1)
Now put the slope in for m and the two coordinates in for (x1, y1).
y - 3 = -1/4(x - 2)
Now that we have this, solve for y for the slope-intercept form.
y - 3 = -1/4x + 1/2
y = -1/4x + 7/2
