Answer:
v < 2
Step-by-step explanation:
1+4v<9
Subtract 1 from each side
1-1+4v<9-1
4v < 8
Divide each side by 4
4v/4 <8/4
v < 2
Answer:
False
Step-by-step explanation:
Use the order of operations
45 * 89 = 4005
4005 + 67 = 4072
55 - 56 = -1
4072 < -1
The answer is false.
Answer:
, for all 
Step-by-step explanation:
The velocity vector is found by deriving the position vector depending on the time:

In turn, acceleration vector is found by deriving the velocity vector depending on time:

Velocity and acceleration vectors at
are:

Norms of both vectors are, respectively:

The angle between both vectors is determined by using the following characteristic of a Dot Product:

Given that cosine has a periodicity of
. There is a family of solutions with the form:
