The answer is 126.58
You first double the 4 which is 16, then you multiply the 16 by 25 to get 400. Next, you have to subtract 25 from 15 to get 10. Then, you square root the 10, becoming 3.16
Finally, you divide the 400 by 3.16 to have the final answer: 126.58
We will use vertex form of the parabola:
Where (h,k) is the vertex of our parabola. We know that focus and directrix are located at the same distance from the vertex. That distance is a.
We can use this to build a system of equations to calculate a and k. We already know that h=-5, keep in mind that focus and vertex share the same x coordinate.
We just add these two equations together:
We plug this back into the first equation:
That's all the information we need to write down the equation:
None of the answers you provided are correct.
The answer is here. You just multiply the fractions because of L • W
Hello!
