Answer:

F, I only

Step-by-step explanation:

We can see this is a quadratic equation and c is the constant. What changes when we change the constant? It will change the h intercept which we can see is also known as a y intercept (the y axis is renamed as h).

You can also use graphs to visualize this, try changing the constant in the equation and you can see the y intercept change.

so the answer is F, I only.

Find an equation of a parabola with a vertex at the origin and directrix X = 2.5

adell [148]

Vertex=(0,0)
directrix is x=2.5
or x-2.5=0
so focus S is (-2.5,0)
let P(x,y)be any point on the parabola.
Let M be the foot of perpendicular from P(x,y) on the directrix.
then SP=PM
$\sqrt{(x-(-2.5))^2+(y-0)^2} =| \frac{x-2.5}{( \sqrt{1})^2 } |
squaring both sides$ $(x+2.5)^2+y^2=(x-2.5)^2 , x^2+6.25+5x+y^2=x^2+6.25-5x
$
$y^2=x^2+6.25-5x-x^2-6.25-5x=-10x
so eq. is y^{2} =-10x$

Find the least common multiple of 3 and 5:

3: 3,6, 9,12,15,18,21

5: 5, 10, 15, 20

The least common multiple is 15. This means every 15 days they will be the same day.

Add 15 days to May 5:

5 + 15 = 20

The next day would be May 20
