If an object moves 40 m north, 40 m west, 40 m south, and 40 m east, what's the total displacement?
2 answers:
Answer:
B. 0 m
Step-by-step explanation:
We are given the movement of an object and are required to find the total displacement.
Now, as we know that 'displacement' refers to the length of the shortest path between two points.
i.e. We are required to find the shortest path the object covers.
Now, we can see from the figure below that the given movement,
40 m north → 40 m west → 40 m south → 40 m east,
will bring the object back to the original position ' O '.
Hence, the total displacement will be 0 m.

The asymptote of the parent function 
, like any other similar exponential function is y = 0.
But in this case the parent function is transformed. It is shifted vertically upward by 4 units. When an exponential function is shifted vertically up or down its asymptote is also shifted by same number of units.
Hence, the asymptote of
will be shifted 4 units above as compared to the asymptote of 
.Therefore, the asymptote of is y=4
