A plane intersects both nappes of a double-napped cone but does not go through the vertex of the cone. What conic section is for
lisabon 2012 [21]
<span>When a plane intersects both nappes of a double-napped cone but does not go through the vertex of the cone, the conic section that is formed by the intersection is a curve known as hyperbola. 
 The standard form of the equation of the hyperbola is shown below:
 [(x-h)^2/a^2]-[(y-k)^2/b^2]=1 (Horizontal axis)
 </span>[(y-k)^2/a^2]-[(x-h)^2/b^2]=1 (Vertical axis)<span>
  Therefore, the answer is: Hyperbola.

hjlf
Choose any 2 points from the table:

<span>*10----------------------$25
*15----------------------$35
*20----------------------$45
*25----------------------$55

and find the slope of the line.  Supposing we focus on

</span>*15----------------------$35
*20----------------------$45

then:
                     $45-$35         $10
slope = m = ------------- = ---------- = $2/mile

Solve: x=4+(4x-4)1/2
Damm [24]

Answer:

x = 10

Step-by-step explanation:

x = 4 + (4x-4) ^ (1/2)

First, we rewrite the expression:

x = 4 + (4x-4) ^ (1/2)

x = 2 (2+ (x-1) ^ (1/2))

x = 4 + 2 (x-1) ^ (1/2)

From here we get a solution for x = 10

To check it we substitute x = 10 in the expression:

10 = 4 + 2 (10-1) ^ (1/2)

10 = 4 + 2 (9) ^ (1/2)

10 = 4 + 2 (3)

10 = 4 + 6

10 = 10

Answer:

The solution is:

x = 10

The width of a rectangle is 12 units. Can the perimeter x of the rectangle can be 60 units when its length y is 18 units? (1 poi
juin [17]

If the width is 12 and the length is 18, the perimeter of the rectangle is 12 + 12 + 18 + 18, or 60. So yes the perimeter can be 60.
