In this exercise we have to use the properties of the logarithm to write it in one way, like this:

From these recalling some properties of the logarithm, we find that:
- When the logarithm is equal to the base, the logarithm will always be equal to 1.
- Logarithm of any base, whose logarithm is equal to 1, will always have the result equal to 0.
- Two logarithms with the same base are equal when the logarithms are also equal.
given the equation as:

Answer:
Explanation:
If you multiply (x - k)(x + k), you get
which is equal to
. Now you can see that
must be equal to
which is equal to
. Now we just need to solve
. The final answer is
.
Answer:
aw... I wish mine were too. I never get to see any of them :(
Explanation:
I hope you get to see them soon!
It’s either A or E most scientist try to come up with a logical explanation when it comes to nature and why it happens in nature I’m going to say it’s E because they can’t just have a final answer there more and likely going to come up with a rational person explanation
The acceleration of a different speck of dust is 40 m/s.
Since the radius is been given as double and angular velocity will be constant, we can calculate the centripetal acceleration as
a = (2r)ω²
If we substitute the given values of r= 2r , and ω²= 20m/s.
Then we have

Therefore, acceleration of a different speck of dust is 40 m/s.
<h3>What is centripetal acceleration?</h3>
centripetal acceleration can be regarded as acceleration of a body that is traversing a circular path.
