28/8 or 7/2 is the answer to that
Answer:
AB =
Step-by-step explanation:
30-60-90 theorem, usually x is used to explain but I will use y since x is in your problem, just substitute any variable for y
in a 30 -60 -90 triangle
the length opposite the 30 degrees is y
the length opposite the 60 degrees is y
the length opposite the 90 degrees is 2y
since y = 6
y = 6/
rationalizing the denominator
=
if y = , 2y =
Positive+positive= positive
negative+negative=positive
-7+10= negative
4/6 + 2/6= positive
-9.5+4= negative
From an acceleration-time graph, you can work out the area under the graph to find the velocity. There are two triangles on the graph as shown below. The total area of the triangles are
Hence, the distance is 250×30=7500 ft
