A race car passes its first checkpoint at a constant speed of 20 m/s and immediately begins accelerating at a rate of 10 m/s2. How long will the car take to reach the finish line 480 meters beyond the checkpoint?

This problem can be represented using the following equation.

(1/2)10t^2+20t=480

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
