Oscar Corporation is planning to construct an elliptical gate at its headquarters. The width of the ellipse will be 5 feet across and its maximum height along the center will be 3 feet. The company wants to place two bright spots at the foci of the ellipse. How far from the center of the ellipse will the spots be located? A. 2 feet
B. 4 feet - incorrect
C. 3 feet
D. 2.5 feet
E. 3.5 feet

Draw the elliptical gate and show the foci, the width, and height as in the figure below.

Note that

a = 5 ft, the width

b = 3 ft, the height

The center is at (0,0).

The foci are at (c, 0) and at (-c, 0).

The foci are related to a and b by

c² = a² - b²

   = 5² - 3² = 16

c = +4 or -4

The foci are located 4 ft horizontally from the center of the ellipse.

I hope I can help you with your first question!
