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:
, for all 
<u>Answer:</u>
H(G(x)) = 12x - 52
<u>Step-by-step explanation:</u>
We are given the following two functions:


And we are to find the value of H(G(x)).
For that, we will apply the function of H on the function of G.



H(G(x)) = 12x - 52
75,655 million that’s it am I not correct?
Answer:
The answer is X=5
Step-by-step explanation:
2x - 5x = 7-8
-3x = -15
X= -15: (-3)
X=5
