A lake in East Texas was stocked with 3,000 trout in the year 2000. The number of fish in the lake is modeled by f(x) = 3000 + 100x, where x represents the number of years after 2000. Which of the following is the most reasonable domain and range for the function?
Answers
The correct answer is C
Step-by-step explanation:
I found this because the pond already has 3000 fish so y can not be less than 3000. Thus eliminating choice A since it says y>-3000.
That reasoning also eliminates answer D because real numbers can also include negatives.
Finally, since y has to be greater than 3000, answer B is not possible as it says y>0 which means it could be less than 3000.
In conclusion, Answer C is correct

Answers
Answer:
its B on e2020
Step-by-step explanation:
14%
If the Algerian government wishes to raise $9 billion in tax revenue, income tax rate should be 14%.
What should the income tax rate be?
Income tax is a form of tax levied on the income of labor by the government. Income tax reduces the income earned by labor.
In order to determine the income tax rate, take the following steps:
Determine the total income of the workforce: 9,416,534 x $6,844 = 64.45 billion
Now, divide the desired tax revenue by the total income: (9 billion / 64.45 billion) x 100 = 14%

Solve for x and find NM
Answers
Answer:
x = 9, NM = 41
Step-by-step explanation:
Since KL = ML then the triangle is isosceles and LN is a perpendicular bisector, thus
NM = NK , substitute values
7x - 22 = 3x + 14 ( subtract 3x from both sides )
4x - 22 = 14 ( add 22 to both sides )
4x = 36 ( divide both sides by 4 )
x = 9
Thus
NM = 7x - 22 = 7(9) - 22 = 63 - 22 = 41

1 mile = 5280 feet
1 rotation covers 6 feet
x rotations covers 5280 feet
1/x = 6/5280 Cross multiply

The yield of strawberry plants depends on the amount of fertilizer fed to the plants. Agricultural research shows that an acre of strawberry plants will yield 630 pounds of strawberries when 70 cubic feet of fertilizer are applied. If 100 cubic of feet of fertilizer are applied, the yield will be 900 pounds of strawberries. Use linear interpolation to estimate the yield if 73 cubic feet of fertilizer are applied.
Answers
Answer:
657 pounds
Step-by-step explanation:
Given
Represent the amount of fertilizer with x and the yield with y.
So, we have:
[tex](x_1,y_1) = (70,630)[/tex]
[tex](x_2,y_2) = (100,900)[/tex]
Required:
Determine the yield (y) when fertilizer (x) is 73ft^3
Using linear interpolation, we have:
[tex]y = y_1 + (x - x_1)\frac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Substitute the x and y values using
[tex](x_1,y_1) = (70,630)[/tex] and [tex](x_2,y_2) = (100,900)[/tex];
We have:
[tex]y = y_1 + (x - x_1)\frac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
[tex]y = 630 + (x - 70)\frac{(900 - 630)}{(100 - 70)}[/tex]
[tex]y = 630 + (x - 70)\frac{270}{30}[/tex]
[tex]y = 630 + (x - 70)*9[/tex]
Open bracket
[tex]y = 630 + 9x - 630[/tex]
[tex]y = 9x - 630+630[/tex]
[tex]y = 9x[/tex]
To solve for y when x = 73.
We simply substitute 73 for x
[tex]y = 9x[/tex]
[tex]y = 9 * 73[/tex]
[tex]y = 657[/tex]
Hence, the yield for 73 cubic feet is 657 pounds

Answers
Answer:
What is meant by K-coloring algorithm to be "almost" constant-time: is that the pattern through which K-coloring algorithm is applied when coloring a graph is "almost" the same every time the algorithm is applied on any graph
Step-by-step explanation:
What is meant by K-coloring algorithm to be "almost" constant-time: is that the pattern through which K-coloring algorithm is applied when coloring a graph is "almost" the same every time the algorithm is applied on any graph. this is because in the use of K-coloring algorithm no adjacent vertices are colored with the same color and if that happens the lowest numbered color that has not been colored will be applied i.e. a new color.
The aim of the K-coloring algorithm is to color a graph with the least possible amount of different colors while ensuring that adjacent vertices don't get the same color

Rewrite the expression as a product using the GCF and distributive property. 27 + 45
Answers
Step-by-step explanation:
GCF of 27 and 45 is 9
Answer: 9 (3+5)
Step-by-step explanation:
The GFCF of these two numbers is 9 as they can both be divided by it
Distributive property form is when you place the GFC outside parenthesis so that the equation can be multiplied in order to show the original equation and dividing the numbers by the GCF so that it does not give you a larger number than what you started with
27/9=3 + 45/9=5
So, keeping this in mind the distributive property form would be 9(3+5)
