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

The percentage of reduction is 17%
<u>Explanation:</u>
Original price = $21
Reduced price = $17.43
Percentage of reduction = ?
Difference in price = $21 - $17.43
= $3.57
Percentage of reduction = 

Therefore, percentage of reduction is 17%
Answer:
32,27,42,47,52
Step-by-step explanation:
Answer:
The friends live 285 miles apart.
Step-by-step explanation:
Let total distance in miles Sean needs to cover to visit his friend be = 
On first hour distance traveled in miles is = 
Distance left to cover after first hour = 
On second hour distance traveled = 34 miles
Distance to still left to be covered = 194 miles
Total distance to be covered after first hour will be =
= 228 miles
Thus, the equation can be given as:
⇒ 
Multiplying each term with 5 to remove fractions.
⇒ 
⇒ 
⇒ 
Dividing both sides by 4.
⇒ 
∴ 
Thus, the friends live 285 miles apart.
