The graph of y=-0.2x² is ? the graph of y=x².
irga5000 [103]

Answer:

D

Step-by-step explanation:

y = -0.2 x²

This has a negative sign, as opposed to y = x², so it will point in the opposite direction.

The leading coefficient (0.2) is less than 1.  This means the parabola is shrunk vertically, or stretched horizontally.  So the parabola is wider than y = x².

igor_vitrenko [27]

Given :

1 batch of brownies required 15 cup of chocolate.

To Find :

If she has 8/10 cup of chocolate remaining, how many batches of brownies can Mary make.

Solution :

Ratio of cups to batch is :

R=\dfrac{15}{1}

Let , batch produced from 8/10 cup of chocolate is x.

So ,

\dfrac{\dfrac{8}{10}}{x}=\dfrac{15}{1}\\\\x=\dfrac{8}{10\times 15}\\\\x=0.053\ batches

Therefore , she can make 0.053 of a batch.

Hence , this is the required solution.
