Answer:
33.33%
Step-by-step explanation:
from 7 to 9 it's 2 hours and you make 500
and 7 to 11 is 4 hours so you make 1000
then do 1000/3000 to find the percentage you have made
1000/3000 is 33.3333333333...% (the 3333.... never ends)
¿A qué porcentaje anual se han impuesto Q. 8000.00 que en 32 días han producido Q. 140.00? ¿ A qué porcentaje anual se han impuesto Q. 8000.00 que en 32 días han producido Q. 140.00 ?
Based on the amount being taxed, the period of taxation, and the tax, the annual percentage of tax is 19.96%.
What is the annual tax percentage?Assuming this rate was x, the following formula would apply:
Annual rate/ 365 days a year x number of days x amount to be taxed = Tax amount
Solving gives:
x/365 x 32 x 8,000 = 140
701.369863x = 140
x = 140 / 701.369863
= 19.96%

Answer:

28 bags of soil the next week
49 + 28 bags of soil purchased in total
Find the GCF (Greatest Common Factor) of 49 and 28.
49/7 = 7
28/7 = 4 (GCF is 7 since it is the largest number that can divide both 49 and 28 equally)
Factor out the GCF + rewrite division above (optional for visualization)
49/7 = 7 -> 49 = 7 * 7
28/7 = 4 -> 28 = 7 * 4
49 + 28 = 7(7 + 4)

Opposite values are those values which on the number line has the same distance between them and zero. The temperature in each city is PoT=-PhT and PhT =+PoT.
What are opposite values?Opposite values are those values which on the number line has the same distance between them and zero. Although the sign on the values may be difference. For example if the first value is 4, then its opposite value is -4.
In general, the temperature equation for Portland, Maine is stated mathematically as
PoT=-PhT
As it is given in the question that the Portland, Maine and Phoenix, Arizona had opposite values. Also, the temperature in Portland is lower than in Phoenix. Therefore, the temperature in each city can be written as,
PoT=-PhT
PhT =+PoT
Hence, the temperature in each city is PoT=-PhT and PhT =+PoT.

Susan has been thinking about starting her own independent gasoline station. Susan’s problem is to decide how large her station should be. The annual returns will depend on both the size of her station and a number of marketing factors related to the oil industry and demand for gasoline. After a careful analysis, Susan developed the following table:
The Maximax decision is that Susan should build a very large gas station due to the largest value of row maximums.
What is a decision table?A decision table can be defined as a type of table that is used for the graphical representation of the actions to perform, especially based on given conditions and business level rules.
The decision table for Susan’s problem is shown below:
Size Good market Fair market Poor market Row maximum
Small 50,000 20,000 -10,000 50,000
Medium 80,000 30,000 -20,000 80,000
Large 100,000 30,000 -40,000 100,000
Very large 300,000 25,000 -160,000 300,000
Thus, the Maximax decision is for Susan to build a very large gas station due to the largest value of row maximums.
For the Maximin decision, we have:
Size Good market Fair market Poor market Row minimum
Small 50,000 20,000 -10,000 -10,000
Medium 80,000 30,000 -20,000 -20,000
Large 100,000 30,000 -40,000 -40,000
Very large 300,000 25,000 -160,000 -160,000
Therefore, the Maximin decision is that Susan should build a small gas station due to the largest value of row minimums.
For the equally likely decision, we would find the row average:
Row 1 = (50,000 + 20,000 - 10,000)/3 = 20,000.
Row 2 = (80,000 + 30,000 - 20,000)/3 = 30,000.
Row 3 = (100,000 + 30,000 - 40,000)/3 = 30,000.
Row 4 = (300,000 + 25,000 - 160,000)/3 = 55,000.
Hence, the equally likely decision is that Susan should build a very large gas station due to the largest value of row average.

behavior.
the end behavior is:
as x ⇒ ∞, f(x) ⇒∞as x ⇒- ∞, f(x) ⇒∞What is the end behavior of the function?
If we have a polynomial of even degree, then the end behavior in both ends is the same one.
Particularly, in these cases (even degree) we only need to look at the leading coefficient. If it is positive, then as x tends to infinity and negative infinity, the function tends to infinity.
In this case, the polynomial is:
y = 9x⁴ + 8x - 2
Notice that the degree is 4, even, and the leading coefficient is 9 (positive).

Answer:
16П or approximately 50.3)
Step-by-step explanation:
The area of a circle is equal to П*r²
Since the circle is inside a rectangle with side that is equal to 8, we know that d = 8
2r = d
r = 8/2
r = 4
A = П*r²
A = П*16
А = 16П ( or 16*3.141592653589793238... = 50.26548... ≈ 50.3)
Answer:
area = 50.27 [tex]cm^2[/tex]
Step-by-step explanation:
In the diagram, we see that the diameter of the circle is 8cm. Therefore the radius of the circle is 8/2 = 4cm.

Answer:
y ≈ 15272.9(1.06306^x) . . . . from regression tool
y = 15300(1.0624^x) . . . . calculated "by hand"
Step-by-step explanation:
An exponential model is one that uses the exponential function ...
f(x) = a·b^x
to model the data. The value of 'a' is the function value when x=0, the initial value. The value of 'b' is the growth factor, the multiplier between function values for successive values of x.
__
toolAn exponential regression tool makes short work of this. Such tools are available on some calculators, apps, and spreadsheets. All that is required is entering the data into a table and invoking the tool. The one shown in the attachment tells you the model is approximately ...
y ≈ 15272.9(1.06306^x)
__
averagingWe can average the growth rate factors a couple of different ways. When we think of "averaging," we usually think of the arithmetic mean, the sum of values divided by their number. If we average the growth rates in this way, we get ...
average rate of growth =
((161/153) +(173/161) +(184/173) +(196/184) +(207/196) +(220/207))/6 ≈ 1.0624
Using the first table value as the initial value, the model formed this way is ...
y = 15300(1.0624^x)
__
For exponential growth it may make more sense to compute the geometric mean. This is the n-th root of the product of n numbers. In this case, it reduces to the 6-th root of the ratio of the last to the first:
average rate of growth = (220/153)^(1/6) ≈ 1.0624
This gives the same growth factor as above, hence the same model.
The second attachment shows the application of this model to the domain used in the table. We see there are some minor differences when rounding the function value to the nearest hundred.
The differences in our two models seem to arise from rounding the data values in the table to the nearest hundred.
__
summaryThe values given in the table can be used in different ways to arrive at two similar, but different exponential models of the table data:
y = 15272.9(1.06306^x)y = 15300(1.0624^x)Interestingly, the function calculated "by hand" has a very slightly better correlation with the table data. The difference in correlation coefficients is in the 6th decimal place.

. a^-n = 1/a^n
. (a^4)^5 = a^5×4 = a^20
Note : When two base are equal , we equate the Exponents.
3^4x-5 = (1/27)^2x+10
= 3^4x-5 = (27^-1)^2x+10
= 3^4x-5 = (3^-3)^2x+10
= 3^4x-5 = 3^ -3(2x+10)
= 3^4x-5 = 3^ -6x-30
The two base are 3 so we equate the exponents.
= 4x - 5 = -6x - 30
= 4x + 6x = -30+5
= 10x = -25
= 10x/10 = -25/10
x = -25/10
x = - 5/2
X is -5/2

The graph of the parent function f(x) = x3 is translated to form g(x) = (x – 7)3 + 9. The point (0, 0) on the graph of f(x) corresponds to which point on the graph of g(x)?
Step-by-step explanation:
let's write this properly :
f(x) = x³
g(x) = (x - 7)³ + 9
this translation means that every point of f(x) is shifted up by 9 units (by the "+ 9" term), and shifted right by 7 units (the " x - 7" term means that for every x the original result of x-7 happens, so, 7 units "later" or more to the right than originally).
so, the original (0, 0) point corresponds to (7, 9).
