I could be 7- or it could be just 7
For a:
(2400*2*PI)/60(seconds) = 80 PI RAD/Sec
For b:
arc length s= radius r * central angle(in radians)
= ((80*pi*7.5)/(2*pi)
=25

Answer:
Minimum value of f(x) = -1.
Step-by-step explanation:
We convert it to vertex form:
x^2 - 6x + 8
= (x - 3)^2 - 9 + 8
= (x - 3)^2 - 1
The minimum value occurs when (x - 3)^2 = 0 because a square has a minimum value of zero ( it cannot be negative for real values of x).
So the function has a minimum value of -1.
