Step-by-step explanation:

This is the equation of the ellipse. Since the denominator is greater for the y values, we have a vertical ellipse. Remember a>b, so a
The formula for the foci of the vertical ellipse is
(h,k+c) and (h,k-c).
where c is
Our center (h,k) is (2, -5)

Here a^2 is 9, b^2 is 4.



So our foci is

and

1.) enlargement b/c the number is more that 1
2.) reduction b/c the number is less than 1
3.) enlargement b/c the number is more than 1
4.) reduction b/c the number is less than 1
5.) reduction k = 1/3
6.) enlargement k = 5/2 or 2.5

Volume is the product of the three dimensions...
V=xyz in this case:
V=3*10*5
V=150 yd^3
Answer:
x=114
Step-by-step explanation:
-11=x/-6+8
-19=x/-6
x=114
Step-by-step explanation:
First, we consider the calculation towards finding the total number of passengers who had booked the train in Florence. The main question to ask in answering this problem is

This statement can be phrase mathematically using the method of ratio and proportion as shown below
,
in which the variable
is the total number of passengers who booked the train from Florence.
Now, rewriting the above ratio into the form of fractions, yields

Given that a quarter out of all reservations is from Florence, then using the same method as before to evaluate the number of passengers that had booked the train (from both Bologna and Florence).
,
where the variable
denotes the total number of bookings.
Therefore, the total number of passengers that had booked the train is 200.
Now, it is stated that all passengers who booked had boarded the train from Bologna which is 150 passengers (three-quarters of total bookings). Then, 36 passengers from earlier got off in Florence, while 20 passengers boarded.
Number of passengers left when arriving Rome = 150 - 36 + 20
= 134 passengers
