Which of the following numbers is the smallest 0.008 or 1/3 or 0.048 or 0.36 or 1/9
RideAnS [48]

Answer:

The smallest number is 0.008

Step-by-step explanation:

To find out which number is the smallest we convert the decimals to percentages

That's

0.008 × 100= 0.8%

1/3 × 100 = 33.3%

0.048 × 100 = 4.8%

0.36 × 100 = 36%

1/9 × 100 = 11.1%

Comparing from the above percentages the smallest one is 0.8% which is

0.008.

Hope this helps you.

Find the average rate of change over the interval [-1,2] (from x = -1 to x = 2) for the graph below
Lyrx [107]

Hello!

Find the coordinate where x = -1:

At x = -1, y = 1, so the coordinate is (-1, 1).

Find the coordinate where x = 2:

At x = 2, y = -2, so the coordinate is (2, -2).

Find the rate of change between the points using the slope formula:

slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Plug in the coordinates above:

slope = \frac{-2-1}{2-(-1)}

Simplify:

slope = \frac{-3}{3} = -1

Thus, the rate of change between the points is -1.
