The relation between the linear and recursive functions are given as follows:
f(n) = -n < - > {-1,-2,-3,-4...}, where f(1) = 1 and f(n + 1) = f(n - 1) - 1 for n > 1.f(n) = 2n - 3 < - > {-1,1,3,5...}, where f(1) = -1 and f(n + 1) = f(n - 1) + 2 for n > 1.f(n) = -n + 5 < - > {4,3,2,1...}, where f(1) = 4 and f(n + 1) = f(n - 1) - 1 for n > 1.f(n) = 2n + 2 < - > {4,6,8,10...}, where f(1) = 4 and f(n + 1) = f(n - 1) + 2 for n > 1.What is a linear function and how does it relate to a recursive function?A linear function is modeled according to the following rule:
f(x) = mx + b
In which:
m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis, that is, when x = 0.Considering the concepts of a linear function, the recursive function is given as follows:
f(n) = f(n - 1) + m for n > 1. f(1) for n = 1. (numeric value of the linear function when x = 1).The linear function with first term -1 and slope -1 is given by:
f(n) = -n.
Hence:
f(n) = -n < - > {-1,-2,-3,-4...}, where f(1) = 1 and f(n + 1) = f(n - 1) - 1 for n > 1.
The linear function with first term -1 and slope 2 is given by:
f(n) = 2n - 3
Hence:
f(n) = 2n - 3 < - > {-1,1,3,5...}, where f(1) = -1 and f(n + 1) = f(n - 1) + 2 for n > 1.
The linear function with first term 4 and slope -1 is given by:
f(n) = -n + 5
Hence:
f(n) = -n + 5 < - > {4,3,2,1...}, where f(1) = 4 and f(n + 1) = f(n - 1) - 1 for n > 1.
The linear function with first term 4 and slope 2 is given by:
f(n) = 2n + 2
Hence:
f(n) = 2n + 2 < - > {4,6,8,10...}, where f(1) = 4 and f(n + 1) = f(n - 1) + 2 for n > 1.

Answers
A . 3 pounds of potatoes
B . 2 pounds of potatoes
A . Janice will purchase potatoes until the value of potatoes is less than the cost of potatoes. Janice has $5.00 to spend on potatoes and the cost of potatoes is $1.00.
By assuming that the First pounce of potatoes is worth $1.50. which is greater than $1.00. If the second pound is worth $1.14, then Janice will purchase these as well, since the value is more than $1.00. If the remaining pounds are worth $0.30 then Janice will not purchase these because the value is less than the cost.
Thus Janice will purchase 3 pounds of potatoes for the Total cost of $3.00
B. Now assume Janica has only $2.00 to spend on potatoes. She will purchase the first pound which is $1.50 and the second pound which is $1.14. She now spends her entire amount of money on potatoes. If she want to purchase she could not do that.
Thus Janice will purchase 2 pounds of potatoes at a total cost of $2.00

Because of the kind of number (28.6925), you will have to round up.
To round up the number has to be a 5 or higher. Well, you have a 9 and then a 2. A 2 can't round up a 9, so you just end up discarding the 2 and the 5 at the end of the number.

this equation is 75x + 45h = T
from this question we know that he worked 2 jobs and made a total of 456$

Answers
Total charge by company A for 80 sq.feet = 250+10(80)= $1050
Total charge by company B for 80 sq.feet = 90+12(90)=$1170
Let x be the no.of square feet for landscaping
Company A
Monthly consulting fee = $250
Cost of landscaping of 1 sq.feet = $10
Cost of landscaping of x sq.feet = $10x
So, Total charge by company A = 250+10x ---1
Company B
Monthly consulting fee = $90
Cost of landscaping of 1 sq.feet = $12
Cost of landscaping of x sq.feet = $12x
So, Total charge by company B = 90+12x ---2
Now we are supposed to find how many square feet of landscaping will the two companies charge the same amount
So, Equate 1 and 2
250+10x = 90+12x
160=2x
80=x
So, the two companies charge the same amount for 80 sq.feet
Total charge by company A for 80 sq.feet = 250+10(80)= $1050
Total charge by company B for 80 sq.feet = 90+12(90)=$1170

Answers
The percentage decrease is 9.83%.
The previous year Springfield middle school students were 620. This year it is 559 students.
Here we have to find the decrease in the percentage of students from the previous year.
The decrease in the students = 620- 559
= 61
Percentage decrease = (decrease/number of students last year)× 100
= (61/ 620 )× 100
= 0.09838 ×100

Therefore the percentage decrease in the number of students from the previous year is 9.83%

How to determine the length of the hypotenuse by trigonometric functions
Right triangles are triangles such that one of its internal angles is a right triangle. Fundamentally, trigonometric functions are relationships between two distinct sides of a right triangle.
The picture show that the length of one leg and the measure of the angle between that leg and the hypotenuse are known, but the length of the hypotenuse does not. By using concepts of trigonometric functions, we can find the length of the hypotenuse by using the cosine function:

We need to know the concept of mean and standard deviation to solve the problem.The standard deviation of the data set is 18.36
The given dataset is 1,2,3,3,4,4,4,4,5,5,6,70, inorder to find the standard deviation of the data set we need to first find the mean of the dataset. Mean of a dataset means the average of the set of numbers. We divide the sum of all the numbers in the data set by the size of the set. We represent mean by μ.
μ=[tex]\frac{1+2+3+3+4+4+4+4+5+5+6+70}{12} =\frac{111}{12} =9.25[/tex]
Standard deviation measures the dispersion of a dataset relative to it's mean, the square of standard deviation is variance.
The formula for standard deviation is :
σ=[tex]\sqrt{\frac{(1-9.25)^{2}+(2-9.25)^{2} +...+(70-9.25)^{2} }{12} } =\sqrt{\frac{68.0625+52.5625+78.125+110.25+36.125+10.5625+3690.5625}{12} } \\=\sqrt{\frac{4046.25}{12} } =\sqrt{337.1875} =18.36[/tex]
