Move the left dot to the left two ticks and the right dot to the right one tick
Answer:
a. x² +4y² +4z² = 1
b. x² +4y² +z² = 1
Step-by-step explanation:
a. In "intercept form", the given equation can be written as ...
(x/1)² + (y/(1/2))² = 1
When the ellipse is revolved around the x-axis, the z-intercept will match the y-intercept, so the equation becomes ...
(x/1)² + (y/(1/2))² + (z/(1/2))² = 1
x² +4y² +4z² = 1
__
b. Likewise, revolving the figure around the y-axis will make the z-intercept the same as the x-intercept. That equation is ...
x² + 4y² +z² = 1
__
See the attachments. The first shows revolution about the x-axis; the second shows revolution about the y-axis.
Answer:
i am confused
Step-by-step explanation:
i am sorry
To fill:
6 hours = 1 tank
1 hour = 1/6 tank
To drain:
It takes 4 times as long, therefore 4 x 6 = 24
24 hours = 1 tank
1hour = 1/24 tank
If both pipes are open
1 hour = 1/6 - 1/24 = 1/8 tank
1/8 tank = 1 hour
8/8 tank = 1 x 8 hour
1full tank = 8 hours
