A race car makes one lap around a race track of radius 50.0 m in 10.0 s. Calculate the average velocity.

for the points

step-by-step explanation:

this doesn't make sense lol

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to
