Answer:
Option D (7, -3)
Step-by-step explanation:
We know that the general equation of an ellipse has the form:

Where the point (h, k) are the coordinates of the center of the ellipse
In this case the equation of the ellipse is:

Then

So The coordinates of the center of the ellipse are (7, -3)
He buys three cups of hot choclate cause 1.50*3= 4.50

Step-by-step explanation:
Answer:
35 feet.
Step-by-step explanation:
To find this, we will need to use the Pythagorean theorem to solve for the diagonal length. Call this diagonal length 'd'.
d² = 21² + 28²
d² = 1225
d² = 35.
Thus, the diagonal length is 35 feet.
