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.
9. In two years it would be (2,20) find the point on the grid and mark the spot.
In three years it would be (3,40) also mark that spot on the grid.
In four years it would be (4,80) mark this point on the grid
All I'm doing is finding the number of the year and going up till it meets the red line or population amount.
Hope this helped you a little.
Answer:
(-18,9)
Step-by-step explanation (work shown in picture attached):
1) The first step in solving by substitution is to isolate the y-term in one of the equations if it is not already isolated. Isolate y in the first equation by dividing both sides by -2. This leaves us with the equation
2) Now, substitute
for the y in the second equation. Simplify and isolate x. (You can multiply everything by -2 to get rid of the fraction.) This leaves us with x = -18.
3) We've found the x-value of the solution, -18. Now, substitute -18 for x back into one of the original equations (I chose the first one because it was simple) and isolate y. This gives us y = 9. Thus, in point form, the answer is (-18,9).
Answer:
<u>18 waves</u> hit the beach in 49 s.
Step-by-step explanation:
Given:
The frequency of the waves that were coming into the beach is 0.367347 Hz.
Now, to find the number of waves that hit the beach in 49 s.
Let the number of waves be 
The frequency of waves (
) = 0.367347 Hz.
The time it takes to hit the beach (
) = 49 s.
Now, we put formula to get the number of waves:

<u><em>The number of waves = 18.</em></u>
Therefore, 18 waves hit the beach in 49 s.
