Answer:
AB = 32
Step-by-step explanation:
Since line l bisects AB at point M, we have AM = MB.
AM = 4(4) = 16, MB = 5(4) - 4 = 16.
So AB = AM + MB = 16 + 16 = 32.
Answer:
- time: t = -0.3
- minimum: v = 0.55
Step-by-step explanation:
For quadratic ax^2 + bx + c, the extreme value is found at x=-b/(2a). For your quadratic, the minimum is found at ...
t = -(3)/(2(5))
t = -0.3 . . . . . time of minimum velocity
__
The value of velocity at that time is ...
v = 5(-0.3)^2 +3(-0.3) +1 = 5(.09) -.9 +1
v = 0.55 . . . . . value of minimum velocity
