If vertex of this parabola is (-5,4) what’s the equation

For this case, we have by definition, that the standard equation of a parabola is:

This equation can also be written in the "vertex form":

Where:

The vertex of the parabola is the point (h, k)

In this case we have:

So:

If a <0 opens down

If a> 0 opens up

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
