45 minutes i m sure all you do is count up or subtract 60 from 15
Vertex form is
![y = a {(x - h)}^{2} + k](https://tex.z-dn.net/?f=y%20%3D%20a%20%7B%28x%20-%20h%29%7D%5E%7B2%7D%20%20%2B%20k)
where (h,k) is the vertex.
We can see that the vertex of the graph is at (2,0), and that the graph opens downwards, but does not look stretched at all.
Therefore,
a = -1
h = 2
k = 0
and our vertex form equation is
![y = - {(x - 2)}^{2} + 0](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%7B%28x%20-%202%29%7D%5E%7B2%7D%20%20%2B%200)
which is answer A
Answer:
28
Step-by-step explanation:
First, find the ratio between the triangles. To do this, divide any side of the big triangle by corresponding side in the small triangle. I chose 35. So, 35/10 = 3.5. 3.5 is the ratio between the triangles. Multiply 3.5 by 8 to get 28, the length of the missing side. :)
