Oscar Corporation is planning to construct an elliptical gate at its headquarters. The width of the ellipse will be 5 feet acros
s 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?
1 answer:
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
Answer:
The foci are located 4 ft horizontally from the center of the ellipse.
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
Answer:
The foci are located 4 ft horizontally from the center of the ellipse.
