Step-by-step explanation:
The parabola has its concavity downwards, so we need a function in the model:

With a negative value of 'a'
The vertex is (0,0), so we have that:


The x-coordinate of the vertex is given by the equation:



So we have a function in the model:

With a < 0
The only option with this format is B:

Answer:the frist on
Step-by-step explanation:
there 5 canby bars and there are 8 boxes so you would do(5x8) divided by s and s= 1
32x35=1,120
To solve this equation, all you have to do is put the two numbers in a calculator connected by multiplication sign,
