Answer: In a rhombus, the opposite angles are congruent, and the adjacent angles are supplementary.
So, no matter how the figure is labeled, it is not a rhombus.
The sum of the interior angles of a quadrilateral is 360°.
Plug 
into the equation of the ellipsoid:
Complete the square:
Then the intersection is such that
which resembles the equation of a circle, and suggests a parameterization is polar-like coordinates. Let
(Attached is a plot of the two surfaces and the intersection; red for the positive root 
, blue for the negative)

Answer:
Yes it is
Step-by-step explanation:
If you us a formula you can predict data points that are not on a graph
In this problem, you are asked to write a number in
scientific notation. In figures, 78 million would look like this:
78,000,000
To write this to scientific notation, you have to move the
decimal point to the left until you will get a number between 1 and 10.
Here, you will have to move the decimal point 7 times to get
7.8
The exponent of the scientific notation is the number of
times you moved your decimal point. Since the movement of decimal point is
going to the left, you will have a positive exponent.
The scientific notation would look like this:
7.8 x 10^7
