Answer:
see explanation
Step-by-step explanation:
For the ellipse
+ = 1
Then the vertices are (a, 0), (- a, 0) and (0, b), (0, - b)
Given
+ = 1
Then
a² = 4 ⇒ a = 2 and b² = 100 ⇒ b = 10
Hence the vertices are
(2, 0), (- 2, 0) and (0, 10), (0, - 10)
I believe it's the first one although I'm not 100% sure tbh
<u>Answer:</u>
Yes,two planes descending at the same angle
<u>Explanation:</u>
Given the angle of deviation as seen by the pilot is equal to 15 degrees,
i.e the angle made by the line of sight with the ground is 15 degrees also the angle of elevation from a person at ground to the other plane is given to be equal to 15 degrees
which means the angle made by line of sight to plane and ground is equal to 15 degrees hence both of these situations refer to the same angle at a point and hence both planes are descending at the same angle.
Keeping in mind that, there are 3.78 liters in 1 US gallon and say 30days per month and 24 hours in a day.. then
