Hi! :)
5/100 = 0.056 sales tax
$12 + $26 + $125 = $163 total purchase without tax.
163 * 0.056 = 9.128 tax based on how much she bought.
$163 + 9.128 = $172.128 total amount she paid.
Answer:
16
Step-by-step explanation:
just use a mean absolute deviation calculator next time
The "parent function" is y = (log to the base 2 of) x
The domain of this function is (0, infinity) (all real numbers greater than zero).
The range of this function is the same as above.
If you replace "x" with "x+1" in the parent function, the associated graph will look the same as that of the given function, EXCEPT that it will be translated by 1 unit to the left.
After this has happened, that "-3" will shift the entire new graph downward by 3 units.
A circle's size and shape is fully defined by its radius. Given two circles with radii r and r', the diameters are d=2r and d'=2r' and they are in the ratio
<span>d'/d = (2r')/(2r) = r'/r. </span>
<span>The diameter ratio is the same as the radius ratio. Similarly, the circumferences c=πd and c' = πd' are in the ratio </span>
<span>c'/c = (πd')/(πd) = d'/d = r'/r </span>
<span>The circumference ratio is the same as the diameter ratio and the radius ratio. All of the key linear dimensions are in the same proportion. </span>
<span>You might point out that the same thing happens with a square, where the size and shape are also completely determined by a single measurement, the length s of a side, with the diagonal and perimeter (corresponding to diameter and circumference) being d = √2 s and p = 4s. </span>
<span>Maybe you can lead at least some of the students to generalize to other regular polygons. Some of them (like the equilateral triangle and regular hexagon) can be demonstrated like the square and circle above with formulas from geometry. The general case needs trig ratios to state the formulas relating side length to the radius and apothem of the polygon.</span>
In order to find the range of a data set, you need to order the numbers in the set from least to greatest. Ex: 9, 3, 8, 7, 4, 1, 2, 6, 5 = 1, 2, 3, 4, 5, 6, 7, 8, 9 Then you subtract the smallest number in the data set from the largest number. Ex: 9 - 1 = 8. The answer that you get from subtracting is the range of the data set. Hope this helps.
