Answer:
- about x: 25x² +4y² + 4z² = 1
- about y: 25x² +4y² +25z² = 1
Step-by-step explanation:
When the figure is revolved around the x-axis, its extent in the z-direction will match its extent in the y-direction. So, the z-term will have the same coefficient as the y-term. 25x² +4y² +4z² = 1
Similarly, when the figure is revolved around the y-axis, its extent in the z-direction will match its extent in the x-direction. Then the z-term will have the same coefficient as the x-term. 25x² +4y² +25z² = 1
The correct answer is 24 mpg (rounded).
Hope this helps.
If you could put in the tablet.
But the equation would be: a_n = a_1 (r)^(x-1)
with a_1 being the first category
r being 5 how much brighter than the day before is
and x is what nr. in the sequence it is
But I'm not sure as I cannot see the table
To get slope-intercept form we have to multiply x-1 by -4 and simplify it then
y=12+(x-1)(-4)
y=12+x*(-4)-1*(-4)
y=12-4x+4
y=-4x+16 - its the result
