HELP PLEASE this is geometry and i don't understand anything on this test

Mathematics
1 answer:
sveta [45]2 years ago
8 0

Answer:

It could be 8 or 5. I think it's 5

Step-by-step explanation:

This is a pretty weird problem. I see the DC is 10 so then one would think that it is 5. EF however is 7. I think the most logical answer would be 5. Using process of elimination, we can narrow it down to 5 and 8 but I feel that 5 makes more sense. the other 2 sides are obviously longer so 5 is most likely correct.

Vertex = (2,5), Point (0, 1)
Rama09 [41]

Answer:

therefore y= - (x-2)^2 + 5

Step-by-step explanation:

u do this by using this format here ..,

y=a(x-h)^2+k

sub in the vertex points as h=2 and k = 5 , since the 2 is positive its sign will be -2 in the brackets because when solving for x-2=0 it is x=2

y=a(x-2)^2+5

then with your (0,1) points plug that in as y and x

1=a(0-2)^2+5

1=a(-2)^2+5

1=4a+5

1-5=4a

-4=4a

a=-1

therefore y= - (x-2)^2 + 5
