Answer:
c
Step-by-step explanation:
every vertical line must doesn't have any accident with graph like the graph C.
Even though it may look like the option is E the real answer is that the variables are invesely related. So your answer will be D
Initial velocity: v o = 30 m/s
h = 75 m
h = v o * t + g * t² / 2
75 = 30 · t + 9.8 · t² / 2
75 = 30 t + 4.9 t²
An equation is:
y = 4.9 t² + 30 t - 754.9 t² + 30 t - 75 = 0
t = 1.9 s
Its the second choice down. x is an element of the intersection of B and C. A is not part of that, and since B and C overlap, it's the intersection, not the union (U).
