Answer:
Step-by-step explanation:
Proper scientific notation means that there is only 1 number to the left of a decimal and everything else to the right of it. Also, because the number is initially less than 1, the exponent will be a negative one. We have to move the decimal 4 places to the right in order to get the 6 to the left of it, so in correct scientific notation format, we have
Answer: The required factored form of the given expression is
Step-by-step explanation: We are given to find the factored form of the following algebraic expression:
We will be using the following formula:
Now, we have
Thus, the required factored form of the given expression is
Answer: or
Step-by-step explanation:
The volume of a cylinder can be found with the following formula:
Where "r" is the radius and "h" is the height of the cylinder.
In this case, let be:
- the volume of one of this cylinders and
the volume of the other one.
- the radius of the first one and
the radius of the other cylinder.
- the height of one of them and
the height of the other cylinder.
Then:
Therefore, you know this:
Simplifying, you get:
Now, knowing the ratios given in the exercise, you can substitute them into the equation:
Evaluating, you get:
