To answer this question, we need to know what absolute value is in the first place. <u><em>ANSWERS ARE AT THE BOTTOM.</em></u>
Absolute value represents how far something is from 0 in a number line.
For example, lets take 4.
4 is 4 units away from 0 on the number line, so the absolute value of 4 is 4.
Now lets look at another example, -4. -4 is also 4 units away from 0, just in the other direction. However, when calculating absolute value, we do not care about the direction. Therfore, the absolute value of -4 is also 4.
Now let's look at your problem.
You want the <em>absolute value</em> of 0 and -4/5
<u><em>Following the same principle above about the distance from 0, here are your answers:</em></u>
<u><em></em></u>
<u><em>Absolute value of 0</em></u><u><em>: </em></u><em>0</em>
<em></em>
<u><em>Absolute value of -4/5</em></u><u><em>: </em></u><em>4/5</em>
Changing the subject of the formula into v means expressing v in terms of the other given variables. So given the original equation, as shown below, we can rearrange it so that we have v isolated on one side.
To isolate v, we can just multiply s to both sides and come up with the final equation below.
Thus, we have v = s(1 - F/f) with v as the subject of the formula.
Answer: v = s(1 - F/f)
Answer:
1.728×10¹⁵
Step-by-step explanation:
You may recall from 3rd grade that multiplying by 10 adds a zero to the right of a number (moves the decimal point 1 place to the right).
An exponent is used to signify repeated multiplication. These facts together are used to translate to/from scientific notation.
10 = 1 × 10
100 = 1 × 10 × 10 = 1 × 10²
__
Continuing in like fashion, 5.4×10⁸ represents 5.4 × (1 followed by 8 zeros).
Similarly, 3.2×10⁶ = 3.2 × (1 followed by 6 zeros)
The product will be ...
(5.4×10⁸)×(3.2×10⁶) = (5.4×3.2) × (1 followed by 8+6 = 14 zeros)
= 17.28 × 10¹⁴
= (1.728 × 10) × 10¹⁴ . . . moving the decimal point so there's 1 digit to its left
Adding that extra zero into the count we already have, this becomes ...
= 1.728×10¹⁵

<em>Additional comment</em>
Your scientific or graphing calculator will have a mode for showing numbers in scientific notation. You can enter these numbers directly into your calculator and have it show you the result in scientific notation.
Or, you can use a spreadsheet with appropriate output cell formatting.
To graph this problem you have to place a point on 20 and go down 5 and go over 2 to the right and do the opposite, (5 up over 2 on the left) and then you just connect the dots.
Answer:
90%
Step-by-step explanation:
18/20 × 100 = 90%
I hope this helps!
