Just find the GCF of the numerator and the denominator after multiplying across.
Answer:
500 vinyl records for $25 and 20 vinyl records for $1
Step-by-step explanation:
you have to multiply 500 by 25 and you get 20 records forjust 1 dollar
The correct answer is A.
In order to find the correct answer in this one, you have to group all of the like terms. In this case, each term is unique with the exception of the x^2y^3 terms. Therefore, we need to check those first.
4x^2y^3 - (-5x^2y^3)
4x^2y^3 + 5x^2y^3
9x^2y^3
Since this term is included, we look for answers that involve this one. A is the only one that does. Plus, it includes each other term unchanged (which is good since there are no other like terms). Therefore, A is your answer.
Answer:
Step-by-step explanation:
To find the values of the angle which makes maximum r you use the derivative of r

If you equals this derivative to zero you obtain the value of the angle:

However, the values of 5π/6 and 9π/6 are also available, because makes the sinusoidal function equal to 1.
hence, the answer is:

answer b
A rotation 270° clockwise would be equal to a rotation 90° counterclockwise.
