X^2-10x+16= 0
(x-8)(x-2)=0
x = 8 or 2
90 trucks- for every 2 cars there are 5 trucks
Answer:
8x
Step-by-step explanation:
Radius = r = 1 foot
Angular velocity = w = 1 revolutions in 4 seconds
So,
w = 0.25 revolutions per second
Since,
1 revolution = 2π radians
We can write the above equation as:
w = 0.25 x 2π radians per second = 0.5π radians per second
Linear Velocity = v = r w
Using the values, we can write:
v = 1 x 0.5π
= 0.5 π
= π/2 feet per second
Therefore, the correct answer is option B
