Answer:
Option (4)
Step-by-step explanation:
From the picture attached,
Side lengths of the triangles have been given in the picture attached.
If these triangles are similar, their corresponding sides will be proportional.
By this property of similarity,
3.9 = 2.5
Which is not true.
Therefore, these triangles are not similar.
Option (4) will be the answer.
Answer:
or 12.5
Step-by-step explanation:
So if 25 - x items are sold, and they each cost x, we can write an equation for the revenue to be
y = (25 - x)x
The vertex of this equation will represent the maximum revenue. So we need to write this equation in vertex form so we can find the vertex.
Vertex from is
y = a(x - h)^2+ k,
where (h,k) represent the vertex.
the vertex form of this equation would be
And the vertex would be
This means the maximum revenue will occur when x = 25/2
