The greatest number of flowers Tina can place in each vase is 8.
Given: Total number of roses: 64
Total number of tulips: 72
Each vase hold same number of flowers. To find the greatest number of flowers that can be placed in each vase.
What is highest common factor?
Highest common factor or HCF between two or more numbers is the process of finding the highest number which can divide all the numbers in a given or the highest number by which all the numbers in the given set are divisible.
The highest common factor HCF is also called greatest common divisor or GCD.
Now, let's solve the given question:
Total number of roses = 64
Total number of tulips = 72
Now it is said that each vase should contain the same number of flowers.
So we have to find the highest possible number which can completely divide 64 and 72 with remainder 0. (divisible)
So, to find the greatest possible number than can divide 64 and 72 we need to find the HCF or GCD of 64 and 72.
Therefore, HCF(64, 72) is 8.
The maximum or greatest number of flowers that can be placed in each vase is 8.
Hence the greatest number of flowers Tina can place in each vase is 8.

, where 
are the coordinates of the vertice and p is the parameter (distance between the focus and the directrix). The parameter is 
. The vertice is the midpoint between the focus and the projection of the focus in the directrix. Then, the vertice is 
. Hence, the parabola is: 
Now, derivating:
