The answer above is mostly correct, HOWEVER The ellipse is a vertical ellipse and therefore uses the equation (x^2/b^2)+(y^2/a^2)=1

a=10/2=5

b=8/2=4

put it in the equation and it is (x^2/4^2)+(y^2/5^2)=1

Simplify and the answer is (x^2/16)+(y^2/25)=1

A = 8/2 = 4
b = 10/2 = 5
Equation of ellipse is given by x^2/a^2 + y^2/b^2 = 1
x^2/4^2 + y^2/5^2 = 1
x^2/16 + y^2/25 = 1

Vesna [10]

Answer: $36.86^{\circ}$

Step-by-step explanation:

Given

Coordinates of Point A is $(-3,-4)$ i.e. Point A is 3 units to the left and 4 units below x-axis

From figure, we can write

$\Rightarrow \tan \theta =\dfrac{3}{4}\\\\\Rightarrow \theta=\tan^{-1}\left(\dfrac{3}{4}\right)\\\\\Rightarrow \theta=36.86^{\circ}$

Two jugs are filled with water. If you remove 1 liter of water from the first jug, then the two jugs contain the same amount of

lyudmila [28]

Let x be the first jug, y the second jug.

From first statement, subtracting 1 from x, makes them equal:
x - 1 = y

From second statement, subtracting 2 from y, makes it half of x:
x/2 = y-2

Solve system with substitution:
x/2 = (x-1) -2
x/2 = x - 3
x- x/2 = 3
x/2 = 3
x = 6

y = x-1 = 6-1 = 5

Therefore the largest jug contains 6 liters.
