Hello, I recommend watching problem 45 again because the set up is very similar. Here's a few things that should help you graph it: The parabola is sideways and opens to the right Vertex: (-1,-5) Focus: 1/4p = 4, so p=1/16 Focus is at (-15/16, -5) Directrix: x=-1 - 1/16 = -17/16 AOS: x=-5 Hope that helps 👍
Hi there! For 44: It's a parabola that opens up. Vertex: (-3,-5) Focus: 1/4p = 1, to solve for p you can cross multiply so we get p=1/4 = 0.25. The y-coord of the vertex is -5 so -5 + 0.25 = -4.75 Focus: (-3,-4.75) Directrix is 0.25 on other side of the vertex (below). 5+0.25 = 5.25 Directrix: -5.25 Hope that helps! 👍
thank you so much, the video was very helpful and you explained it really well!
I'm so happy to hear that! And you're welcome :D
Hello! how about the solution for number 46? Can you help me about it?
Hello, I recommend watching problem 45 again because the set up is very similar. Here's a few things that should help you graph it:
The parabola is sideways and opens to the right
Vertex: (-1,-5)
Focus: 1/4p = 4, so p=1/16
Focus is at (-15/16, -5)
Directrix: x=-1 - 1/16 = -17/16
AOS: x=-5
Hope that helps 👍
@@Eat_Pi what is the length of latus rectum sir?
helloo! how abt the number 44?
Hi there!
For 44:
It's a parabola that opens up.
Vertex: (-3,-5)
Focus: 1/4p = 1, to solve for p you can cross multiply so we get p=1/4 = 0.25. The y-coord of the vertex is -5 so -5 + 0.25 = -4.75
Focus: (-3,-4.75)
Directrix is 0.25 on other side of the vertex (below). 5+0.25 = 5.25
Directrix: -5.25
Hope that helps! 👍
@@Eat_Pi yey thank uu !
Sir I think you saved my GPA
All I want to do is save math lives 🙏
