Answer:

13.35 millimeter. (About)

Step-by-step explanation:

To find the area or circumference of any circle, you need to use pi. So, if we are trying to fine the area of a <em>semicircle, </em>you use the the formula:

πr²/2

So, if the radius is 8.5,

8.5 · 3.14 = 26.69

Now we divide it by 2.

26.69 = 13.345

Since the question is asking to round to the hundredths, the answer will be 13.35 millimeters.

Convert the following to standard form <br><br>y=2/5 x - 1/3​
Afina-wow [57]

<u>Given </u><u>:</u><u>-</u>

  • y = 2/5x - 1/3

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • To convert the given equation into standard form.

<u>Solution</u><u> </u><u>:</u><u>-</u>

As we know that the standard form of the line is ,

\sf\longrightarrow ax + by + c = 0

So the given equation is ,

\sf\longrightarrow y = 2/5x -1/3

\sf\longrightarrow y = 6x - 5/15

\sf\longrightarrow 15y = 6x - 5

\sf\longrightarrow 6x -15y -5 = 0

<u>Hence</u><u> the</u><u> required</u><u> </u><u>equation</u><u> of</u><u> the</u><u> line</u><u> is</u><u> </u><u>6</u><u>x</u><u> </u><u>-15y-5=</u><u>0</u><u>.</u>

Fractional index means "xth root of". Negative index means a fraction. So together, what it really means is:

\frac{1}{\sqrt[5]{32}} = \frac{1}{2}.
