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)
I don't think this is a linear equation. A linear equation has 2 variables.
Answer:
<h2>5 1/4</h2>
Step-by-step explanation:
3 1/2 = 6/2 + 1/2 = 7/2
He drinks 3 1/2 liters every 2/3 hour means
He drinks (7/2)×(3/2) = 21/4 = 5 1/4 liters in one hour.
