Which of the following lists is in order from smallest to largest?
Stells [14]

Answer:

The following list is in order from smallest to largest is 17\%,0.175,\frac{2}{11},\frac{1}{5}

Step-by-step explanation:

Let the numbers be \frac{2}{11},\frac{1}{5},17\%,0.175

To find the list in order from smallest to largest:

\frac{2}{11},\frac{1}{5},17\%,0.175

Rewritting the above numbers as below

0.18,0.5,\frac{17}{100},0.175

0.18,0.5,0.17,0.175

Now arranging the numbers in order from smallest to largest

0.17,0.175,0.18,0.5

\frac{17}{100},0.175,\frac{2}{11},\frac{1}{5}

The arranged numbers can be written as

17\%,0.175,\frac{2}{11},\frac{1}{5}

The following list is the order from smallest to largest is 17\%,0.175,\frac{2}{11},\frac{1}{5}

Make x the subject of the formula y= b/ax
neonofarm [45]

Answer:

x=b/(ay)

Step-by-step explanation:

To make x the subject of the formula, we basically have to isolate the x.

To do this we first multiply both sides by x.

xy=b/a

Now, to isolate the x, we simply divide by y,

x=b/(ay)

So x=b/(ay) is our answer

If the function graphed is f(x), find f(1).
Crazy boy [7]
Locate 1 on the x axis. This is the horizontal number line. 

Draw a vertical line through 1 on the x axis. Extend this vertical line as far up and down as you can.

Notice how the vertical line crosses the blue curve. Mark this point. Then draw a horizontal line from this point to the y axis. The horizontal line will touch -4 on the y axis. So that means the point (1,-4) is on the curve.

If the input it is x = 1, then the output is y = -4

So that's why the answer is choice A
