The graph which shows the velocity of the particle at any time is attached below.
<h3>How to depict the graph?</h3>
The graph is the rate of change of position of an object with respect to time. Velocity is the speed of an object moving in a definite direction.
Velocity is a vector quantity as it has both magnitude and direction. The velocity of a particle is modeled by the function. It is observed that the given velocity function is a cubic function. The attached graph shows the velocity of the particle at any time.

Answer:

Step-by-step explanation:
Given that,
...(1)
We need to find the value of
.
Put n = 1 to find the first term.

Put n = 2 to find the second term.

Put n = 3 to find the third term.

Put n = 10 to find the tenth term.

It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :

We have, n = 10, a = 5 and 
So,

So, the value of
is equal to 280.
Answer:
Last option
Step-by-step explanation:
Given expression is:

The terms can be simplified one by one

As the larger power of x is in numerator, the smaller power will be brought to denominator

Similarly for y,

Applying the radical

So, last option is the correct answer ..
Answer:
no
