Answer:
First option
Explanation:
<u>Operations with functions
</u>
Given two functions f, g, we can perform a number of operations with them including addition, subtraction, product, division, composition, and many others
.
We have
We are required to find
We simply divide f by g as follows
We know rational functions may have problems if the denominator can be zero for some values of x. We must find out if there are such values and exclude them from the domain of the new-found function. We must ensure
or equivalently
Thus the first option is correct
Note: Since 
is always a positive number (for x real), our function does not really have any restriction in its domain
I believe the correct answer from the choices listed above is option B. The statement that is true about the kinetic energy would be that the <span>ball has the least kinetic energy at the top of its flight. Hope this answers the question. Have a nice day.</span>
A. The restoring force is tripled
Answer:
the Prime Meridian is the planets line of 0 degrees longitude sometimes called the Greenwich Meridian or the international Meridian
the great circle of Earth with the latitude of 0 degrees
The conservation of the momentum allows to find the result of how the astronaut can return to the spacecraft is:
- Throwing the thruster away from the ship.
The momentum is defined as the product of the mass and the velocity of the body, for isolated systems the momentum is conserved. If we define the system as consisting of the astronaut and the evo propellant, this system is isolated and the internal forces become zero. Let's find the moment in two moments.
Initial instant. Astronaut and thrust together.
p₀ = 0
Final moment. The astronaut now the thruster in the opposite direction of the ship.
= m v + M v '
where m is propellant mass and M the astronaut mass.
As the moment is preserved.
0 = m v + M v ’
v ’= 
We can see that the astronaut's speed is in the opposite direction to the propeller, that is, in the direction of the ship.
The magnitude of the velocity is given by the relationship between the masses.
In conclusion, using the conservation of the momentun we can find the result of how the astronaut can return to the ship is:
- Throwing the thruster away from the ship.
