Step-by-step explanation:

The second graph is the right one. Note that when x = 1, y (the maximum) is 4, and that the x-intercepts are -3 and 1.

Put these numbers in order from greatest to least. 0.012 0.002 0.02 0.512

prisoha [69]

Answer: 0.512, 0.020, 0.012, 0.002

Step-by-step explanation:

To put these decimals in the order from greatest to least, we first need to make sure they all have the same place values.

0.012, 0.002, 0.020, 0.512

Now that they have the same place values, we can see which is bigger.

0.512, 0.020, 0.012, 0.002

The actual length (L) of a rectangle is 27 centimeters. Use the scale drawing of the rectangle to find the actual width (W).

Dominik [7]

The ratio of the length to the width is $\rm \dfrac{L}{W}$ .
The ratio of the sides will be the same for the scale and actual figures.

$\rm \dfrac{2.4}{3.6}=\dfrac{27}{W}$

I took the L/W of the scale figure
and set it equal to the L/W of the actual figure.

Now we can solve for the unknown width.
Cross-multiplication gives us this,

$\rm 2.4W=3.6\cdot27$

Divide by 2.4 and simplify,

$\rm W=40.5$

Hope that helps! :)
