Answer:
D) a hyperbola
Step-by-step explanation:
IMO, the image is not helpful, as it suggests the ends of the curve are nearly parallel to each other. In fact, the ends of the curve asymptotically approach straight lines parallel to the sides of the cone. That is, there are asymptotes that form an X shape. This is a characteristic of a hyperbola.
___
A parabola is formed when the plane cuts the cone parallel to one side. That cut plane only intersects one nap of the cone. At a shallower angle yet, one gets an ellipse. Parallel to a base, one gets a circle.
Answer:
y=2/3x - 3
Step-by-step explanation:
In order to move an equation down, you just subtract how many units you want to move down on the graph. In this case, you want to move 3 units down, so that's why you subtract by 3. Easy as that!
Answer:
The initial temperature of the coffee was 90°C.
Step-by-step explanation:
The function representing the temperature of the coffee after <em>x</em> minutes is:
T is the temperature in degree Celsius.
The initial temperature of the coffee will be at <em>x</em> = 0.
Compute the value of T (x) at x = 0 as follows:
Thus, the initial temperature of the coffee was 90°C.
Answer:
I think it's C.
