Acceleration is the rate at which velocity (speed) is changing. If an object is moving with a constant velocity, then its acceleration is zero, since the velocity never changes. ... So in that one second, the speed increased by 2 mph.
Answer:
They are congruent, they are right angles

But in this situation, perpendicular lines will always create right angles.
Answer:
A, B, E, and F
Step-by-step explanation:
sinx and cosx are defined for all values of x. So, sin⁻¹x and cos⁻¹x are also defined for all values of x.
A and E are correct.
tanx is defined for all values of x.
However, tan(nπ) = 0 at when n is an integer. So, tan⁻¹(±nx) is undefined. However, tan⁻¹(-½x) is defined, because -½ is not an integer.
B and F are correct.
C and D are <em>wrong</em>. Both sec⁻¹x and csc⁻¹x are undefined when -1 < x < 1, and -½ is in this forbidden region.
