Answer:
the area is 30
Step-by-step explanation:
area of triangle =base×height
so ,
base=7.5
height=4
why , shouldn't we take 5(or)6 as height because we shouldn't take slanting lengths as height.
so apply base and height in the formula
7.5×4=30

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
