Answer:
F. Hyperbola
Step-by-step explanation:
In each napped, you'll have a parabola, combined they form an hyperbola.
It's one of the various shapes that can be produced by a plane intercepting a right circular cone, as you can see in the attached picture.
Each plane intersection is different, based on the angle and the position it passes through.
I hope that helps.
The quadrant would be the first one, because once reflected over the y-axis, it would become (2,-8), and once reflected over the x-axis, it would become (2,8)
Answer: 19.99cm
Step-by-step explanation: trust
1. The problem says that the television has a rectangular shape. So, the formula for caculate the area of a rectangle is:
A=LxW
"A" is the area of the rectangle (A=3456 inches²).
"L" is the the length of the rectangle.
"W" is the width of the rectangle.
2. The <span>width of the screen is 24 inches longer than the length. This can be expressed as below:
W=24+L
3. Then, you must substitute </span>W=24+L into the formula A=LxW:
<span>
</span>A=LxW
<span> 3456=L(24+L)
3456=24L+L</span>²
<span>
4. The quadratic equation is:
L</span>²+24L-3456=0
5. When you solve the quadratic equation, you obtain:
L=48 inches
6. Finally, you must substitute the value of the length, into W=24+L:
W=24+L
W=24+48
W=72 inches
7. Therefore, the dimensions of the screen are:
L=48 inches
W=72 inches<span> </span>
You would subtract 6 from both sides in order to get m by itself. When you do this you get m=-10
