A mathematical connection known as a function is one in which the values of one or more independent variables determine the values of a single dependent variable. Function implies that the independent variable affects the dependent variable (s).
Explain the functions and variables in mathematics? A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics and the sciences, functions are fundamental for constructing physical relationships.We have seen that functions can be stored in variables, and we shall investigate this further later. In JavaScript, a value called an object is a container for additional data like integers, characters, functions, and other objects.We can avoid repeatedly writing the same logic or code in a program by using functions. C functions can be called from anywhere in a program and at any number of times. When a large C program is broken up into several functions, we can simply track it.

Step-by-step explanation:
At the beginning of spring, Khalil planted a small sunflower in his backyard. When it was first planted, the sunflower was 5 inches tall. The sunflower then began to grow at a rate of 1 inch per week. How tall would the sunflower be after 6 weeks? How tall would the sunflower be after w weeks?
The sunflower would be 11 inches tall after 6 weeks and it would be (5+w) inches tall after w weeks .
In the question ,
it is given that
the height of the sunflower when it was planted = 5 inches
rate of growth of sunflower = 1 inch per week
let y represents the height of the sunflower after x weeks .
So , According to the question , the equation becomes
y = 5 + 1*x
to find the height after 6 weeks , substitute x=6
we get ,
y = 5 + 1(6)
y=5+6
y=11
height after 6 weeks will be 11 inches .
to find the height after w weeks , substitute x=w
we get ,
y = 5 + 1(w)
y=5+w
sunflower will be (5+w) inches tall
Therefore , the sunflower would be 11 inches tall after 6 weeks and it would be (5+w) inches tall after w weeks .

suppose that 75% of the applicants for a certain industrial job possess advanced training in computer programming. applicants are interviewed sequentially and are selected at random from the pool. find the probability that the first applicant with advanced training in programming is found on the third interview. (round your answer to four decimal places.)
The probability that the first applicant with advanced training in programming is found on the third interview is 0.0469
Let X denote the number interviewed until 1 has advanced training and follows a geometric distribution with parameter 75%, so
Geometric distribution is: (1-75%)
=0.75
The density function of geometric distribution is,
[tex]P(X=x)=p(1-p)^{x-1}[/tex], for all x = 1,2,3,....
Now, we calculate the probability that the first applicant with advanced training in programming is found on the third interview:
P(X=3) =[tex]0.75(1-0.75)^{3-1}[/tex]
=[tex]0.75(1-0.75)^{2}[/tex]

the time it takes me to wash the dishes is uniformly distributed between 12 minutes and 20 minutes. what is the probability that washing dishes tonight will take me between 14 and 16 minutes?
The probability that washing dishes will take time between 14 and 16 minutes is equal to 25%.
This type of probabilty can be termed a uniform probability in which all the outcomes or results are equally likely.
The lower limit can be represented as a and in this problem is 12 minutes and the upper limit can be considered b and in this problem is 20 minutes.
The equation to find probability, in this case, can be given as:
P ( c ≤ X ≤ d ) = d - c / b - a
Here c = 14 and d = 16 as we have to find the probability that washing dishes will take between 14 and 16 minutes.
Therefore;
P ( 14 ≤ X ≤ 16 ) = 16 - 14 / 20 - 12 = 2 / 8 = 0.25
Converting it into percentage:
0.25 = 0.25 × 100 = 25%
Therefore, the probability that washing dishes will take her between 14 and 16 minutes is calculated to be 25%.

Brian is driving to Miami. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Brian has 69 miles to his destination after 15 minutes of driving, and he has 58.8 miles to his destination after 27 minutes of driving. How many miles will he have to his destination after 41 minutes of driving?
Brian will have 46.90 miles to his destination after 41 minutes of driving.
In the question ,
it is given that
Brian has 69 miles left to his destination after 15 minutes of driving
let x denotes the driving time ( in minutes)
and y denote the remaining distance ( in miles )
so the point is represented by (15,69)
and given that
Brian has 58.8 miles to his destination after 27 minutes of driving
so the second point is (27,58.8).
Since the relationship is given to be linear , hence it will represent a line .
the equation of line passing through the two points (15,69) and (27,58.8) is given by
(y-69)=(58.8-69)/(27-15) * (x-15)
y-69 = -10.2/12 * (x-15)
y-69 = -0.85(x-15)
y-69= -0.85x+12.75
y = -0.85x + 81.75
So , the linear relationship between remining distance and driving time is given by y = -0.85x + 81.75 .
to find miles will he have to his destination after 41 minutes of driving
Substituting x=41 we get
y = -0.85(41) + 81.75
y = -34.85 + 81.75
y = 46.90 .
Therefore , Brian will have 46.90 miles to his destination after 41 minutes of driving.

The value of the smiley face provided in the question is 908.
What is the value of the smiley face ?The first step is to determine the value of each of the shapes.
The value of the rectangle would be determined first. Using the third given equation, let r represent the value of one rectangle.
(4 x r) + (2 x r) - (3 x r) = 15
4r + 2r - 3r = 15
3r = 15
r = 15 / 3 r
r = 5
The next step is to determine the value of the triangle. The second equation would be used. Let t represent the value of the triangle.
(3 x 5) + (4 x t) = 47
15 + 4t = 47
4t = 47 - 15
4t = 32
t = 32 / 4
t = 8
Finally, the value of the star would be determined. Let the value of the star be represented with s. Using the first equation:
5 + (3 x 8) - s = 17
5 + 24 - s = 17
29 - s = 17
s = 29 - 17
s = 12
Now, the value of the smiley face can be determined:
12 x (8 + 12 - 5) + 8(8 . 12 - 5)
12 x (15) + 8(91)
180 + 728 = 908.

The area of a rectangle ABCD is 9cm².
Show that x² + 5x = 3
We can show that x² + 5x = 3 given the dimensions of the rectangle that has an area of 9 cm² as explained below.
How to Find the Area of a Rectangle?To find the area of a rectangle, use the formula given below:
Area of a rectangle = (length)(width).
Given the parameters:
Area of rectangle ABCD = 9 cm²Length of the rectangle = BC = (x + 3) cmWidth of the rectangle = AB = (x + 2) cmTo show that x² + 5x = 3, plug in the values into the formula for the area of a rectangle:
(x + 3)(x + 2) = 9
Apply the distributive property of equality
x(x + 2) + 3(x + 2) = 9
x² + 2x + 3x + 6 = 9
Combine like terms:
x² + 5x + 6 = 9
Add -6 to both sides of the equation
x² + 5x + 6 - 6 = 9 - 6 [subtraction property of equality]
x² + 5x = 3
Thus, if the area of the rectangle with the given dimensions is 9 cm², then we can show that, x² + 5x = 3 as explained above.

The solution for the expression x² = 12 will be x = ±2√3.
The expression is given in the form of square of a variable x which is equal to 12. This expression does not form a perfect square as the constant term is not a perfect square number. A perfect square is a number which is expressed as the square of whole number, or a number multiplied by itself twice. Here, we are given that x² = 12. We take square root of the expression on both the sides then,
√x² = √12
x = √(2×2×3)
x = ±2√3

The lengths of the four sides of a quadrilateral (in feet) are consecutive even integers. If the perimeter is 9292 feet, find the value of the longest of the four side lengths.
The longest side of a quadrilateral with length of consecutive even integers is 26 feet.
How to find the side of a quadrilateral?The lengths of the four sides of a quadrilateral (in feet) are consecutive even integers.
A quadrilateral is a polygon with 4 sides.
Therefore, the sides are consecutive even numbers.
Hence,
smallest side = x
Therefore, perimeter is the sum of the whole sides of the quadrilateral.
x + x + 2 + x + 4 + x + 6 = 92
4x + 12 = 92
4x = 92 - 12
4x = 80
x = 80 / 4
