Bridgette has drawn a representation of a sphere with a radius of 3 units, using the graphs of a circle and an ellipse, as shown in the picture below on the left. She needs to determine the equations of the graphs that will generate the representation of the 3D sphere, as shown in the picture below on the right.

What are possible equations of the circle and ellipse that Bridgette can use to create her 3D drawing?.

D.

Step-by-step explanation:

Circle is x^2 + y^2 = 9

Ellipse is x^2/9+ y^2/1 = 1

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
