Designer wants to create a whisper chamber in the shape of an ellipse. He has a warehouse space with a longest length of 30 feet which he decides will be the major axis of his elliptical chamber. He determines the best spots for his guest to stand to experience his whisper chamber will be 4 feet from the center of the warehouse space, which will act as the foci. How far out from the center along the minor axis should he built his whisper chamber.

28.9 feet

Step-by-step explanation:

From the above question, we have obtained the following values:

Major axis of elliptical chamber = 30 feet

Note that length of the major axis of an elliptical chamber = 2a

Hence, 2a = 30

a = 30/2

a = 15 feet

Focus or foci = c = 4 feet

Length of the minor axis =2b = ??

The formula =

c² = a² - b²

b² = a² - c²

b²= 15² - 4²

b² = 225 - 16

b² = 209

b = √209

b = 14.456832295 feet

How far out from the center along he minor axis should he built his whisper chamber = Length of the minor axis

= 2 × b

= 2 × 14.456832295 feet

= 28.91366459 feet

Approximately = 28.9 feet

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
