To solve this problem yu must apply the proccedure shown below:
1. You have that the <span>focus of the parabola is located at (0,–2) and the directrix is represented by y=2. Therefore, you have:
</span>
√(x0-0)²+(y0-(-2))²=|y-2|
2. By simplifying and clearing x², you obtain:
(√x0²+(y0+2)²)²=(y0-2)²
x0²+(y0+2)²=(y0-2)²
{ Note: x0²=x and y0=y)
x²=-8y
The answer is: x²=-8y
Answer:
The air
Step-by-step explanation:
1. i only know the second part which is the last one <_
Answer:
(21 + 11)2 = 64
So, I don't think teachers do this, but this is my way of doing it
Okay, so first, I divided 64 by 2 :
64 ÷ 2 = 32
Then, I subtracted 11 from 32:
21
Now, to check, just do the problem :
(21 + 11)2 = 64
32 * 2 = 64
The values of k are 4,5,6
