Answer:
It represents an infinite cylinder of radius 4.
Step-by-step explanation:
The first thing to notice is that
<u>represents a circle of radius 4</u>, with its center in the origin of a plane yz, of cartesians coordinates.
Starting from here, we have to put the coordinate x, for all values of x, to complete the space R³. <em>This will enlarge this circle we had on the plane, to infinity</em> (positive and negative on the x-axis).
Finally, we have that this region is a cylinder of radius 4, with center in y=0 and z=0, and of infinite length in the x coordinates.

The equation described above can also be written as, y = -x² + 100x + 4000To get the number of notebooks that will give them the maximum profit, we derive the equation and equate to zero. dy/dx = -2x + 100 = 0The value of x from the equation is 50. Then, we substitute 50 to the original equation to get the profit. y = -(50^2) + 100(50) + 4000 = 6500Thus, the maximum profit that the company makes is $6,500/day.

At the end of the year, Juan has 52.71 more than 4 times his balance at the beginning. Okay, let's set this up.
4x + 52.71
(4 times) (52.71 more)
His ending was 172.90, so
4x + 52.71=172.90
4x= 120.19
x= 30.05
He had $30.05 at the beginning of the year.
21/1 divided by 7/4 = 21/1 x 4/7 = 12.
Hope this helped my guy.
Answer:Ava will have a total of 8 trips to make to total of 25 kilometers
Step-by-step explanation:
Total distance that Ava has already cycled this year is 9 kilometers.
she plans to cycle 2 kilometers during each trip to work.
Let x represent her number of trips to work. Therefore, for Ava to make a total of 25 kilometers, it means that
2x + 9 = 25
Subtracting 9 from both sides of the equation, it becomes
2x + 9 - 8 = 25 - 9
2x = 16
x = 16/2 = 8
