A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x.
In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain.
The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.

Original sides of the square before reducing was 11 inches.
What is a quadratic equation ?A quadratic equation has highest degree of two and it has 2 roots.
According to the given question Miriam reduced a square photo by cutting 3 inches away from the length and the width so it will fit in her photo album.
Assuming sides of the square to be x inches.
∴ From the given data
( x - 3 )( x - 3 ) = 64 ( area of a square is product any two sides )
x² - 6x + 9 = 64
x² - 6x - 55 = 0
x² - 11x + 5x - 55 = 0
x( x - 11 ) + 5( x-11 ) = 0
(x - 11 )( x + 5) = 0
∴ x = 11 or x = -5. ( length of something can not be negative )
So, the original length of the sides of the square is 11 inches.
Original area is

On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal at y = negative 1. Everything above the line is shaded. The second dashed line has a negative slope and goes through (negative 2, 1) and (0, 0). Everything below the line is shaded.
A system of inequalities can be used to determine the depth of a toy, in meters, in a pool depending on the time, in seconds, since it was dropped. Which constraint could be part of the scenario?
Using a linear function, one constraint on the inequality is given by:
y < -0.5x.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points, the slope is given by change in y divided by change in x.
For the line in the inequality, the points are:
(-2,1) and (0,0).
Hence the slope is given by:
m = (0 - 1)/(0 - (-2)) = -1/2 = -0.5.
Hence:
y = -0.5x + b.
When x = 0, y = 0, meaning that the y-intercept is of b = 0, and:
y = -0.5x.
Everything below the line is shaded, meaning that the values of y that are less than the line are shaded, and the inequality is:
y < -0.5x.
The inequality is only less, not less or equal, because the line is dashed and not solid.

What is the simple interest paid if $900 principal 6% interest rate for 2 year
Simple Interest is the method of finding the interest amount for a particular principal amount of money at a particular rate of interest.
The simple interest for $900 at an interest rate of 6% is $108.
What is simple interest?Simple Interest is the method of finding the interest amount for a particular principal amount of money at a particular rate of interest.
We have,
Principal = $900
Rate of interest = 6%
Time = 2 years.
Remember that time should always be in years.
The formula for simple interest is given by:
SI = PRT / 100
Where,
P = principal
R = rate of interest
T = Number of years
So,
SI = 900 x 6 x 2 / 100
SI = $108
Thus the simple interest for $900 at an interest rate of 6% is $108.

The perimeter of a polygon is 24 units.
In this question, we have been given the coordinates of a polygon.
we need to find the perimeter of a polygon.
Let A= (-3,2), B = (2,2), C = (2,-4), D = (-1,-4), E = (-1,-2), F = (-3,-2)
First we find the length of each side of a polygon.
|AB| = √5² + 0²
|AB| = 5
|BC| = √0² + (-6)²
|BC| = 6
|CD| = √(-3)²+0²
|CD| = 3
|DE| = √0²+2²
|DE| = 2
|EF| = √(-2)²+0²
|EF| = 2
|FA| = √0²+4²
|FA| = 4
The perimeter of a polygon would be,
P = AB + BC + CD + DE + EF + FA
P = 5 + 6 + 3 + 2 + 2 + 4
P = 24 units

The slope of the line which passes through the points (4, 18) and (6x, 2k) is (k - 9)/(3x - 2).
According to the given question.
A line passes through points (4, 18) and (6x,2k).
Which means we have two points (4, 18) and (6x,2k).
As we know that, the slope of a line is the ratio of the amount that y increases as x increases some amount.And the slope formula is m=(y2-y1)/(x2-x1) if a lines passes through the point (x2, y2) and (x1, y1).
Therefore, the slope of the line which passes through the points (4, 18) and (6x,2k)
= 2k - 18/ 6x - 4
= 2[k - 9]/2[3x - 2]
= (k-9)/(3x - 2)

In the rectangle shown below, the length is longer than its width w. List all the possible
whole number dimensions for the rectangle, and name the dimensions that give the smallest
perimeter.
Area is 40 m2
Answer: w can be 1,2,4,5
Step-by-step explanation:
Let's recap the formula of Area:
Area = width x length = w x l
Area = 40 = w x l
The definition of a whole number: is a number without fractions; an integer such as 0, 1, 2, 3, 4, 5, 6,...
Let's start with 0. 0 times anything is equal to 0, so we cannot make 40 out of zero. Cross this out.
Next, let's try with 1:
a. 1x40 = 40
Then, applying the same concept to the rest we have these multiplications:
b. 2x20 = 40
c. 4x10 = 40
d. 5x8 = 40
e. 8x5 = 40
f. 10x4 = 40
g. 20x2 = 40
h. 40x1 = 40
Let's recap the formula of Perimeter:
P = 2 x (w + l)
So, we have the calculated perimeters (according to the above finding):
a. P= 2x(1+40)=82
b. P= 2x(2+20)=44
c. P= 2x(4+10)=28
d. P= 2x(5+8)=26
The below answers do not fit the [width < length]
e. P= 2x(8+5)=26 [not an answer]
f. P= 2x(10+4)=28 [not an answer]
g. P= 2x(20+2)=44 [not an answer]

a boy throws a baseball across a field. the ball reaches its maximum height, 18 meters, after 1 second. after approximately 2.3 seconds, the ball lands on the ground. the ball’s motion can be modeled using the function f(x)
The height of the ball after 1.5 seconds is 15.5 meters so option (C) will be correct.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
Given the function as the height of ball f(x) and time x
f(x) = -10x² + 20x + 8
At x = 1.5
f(1.5) = -10(1.5)² + 20(1.5) + 8
f(1.5) = 15.5
Hence "The height of the ball after 1.5 seconds is 15.5 meters".
