It is growing exponentially so this is non linear function of squares of given negative numbers.
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.
Four main categories can be used to classify different sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element. A relation between a domain and range is called a function when each value in the domain only has one value in the range.
Here,
0²=0
-1²=1
-2²=4
-3²=9
Hence, It is a nonlinear function of the squares of the given negative numbers because it is growing exponentially.

What is congruent triangle?When two triangles are congruent, their three sides and their three angles match precisely.If there is a turn or a flip, the equal sides and angles might not be in the same place, but they are still present.Formally speaking, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a combination of rigid motions like translation, rotation, and reflection. Therefore, if two separate plane figures on a piece of paper can be cut out and then perfectly fitted up, they are congruent.It is given that
O is the midpoint of NP,
NP is perpendicular to MN, and
NP is perpendicular to PQ.
When two lines intersect at a specific point, the opposite angles formed in this situation are equal.Then ∠MNP =∠QPO=90°∠MON=∠QOP∠MOP=∠QONTherefore, Triangles MNO and QPO are congruent.

Question What is the decibel level of the noise from a motorcycle with intensity 10-2 watts per square inch? Use a logarithmic model to solve. Provide your answer below: 100 dB
Answers
The decibel level of the noise from a motorcycle with intensity 10⁻² watts per square inch (W/in²) is equal to 50 dB.
What is sound intensity?In Science, sound intensity can be defined as a measure of the power of a sound wave per unit area. This ultimately implies that, sound intensity is a quantity that is typically be used for measuring the energy of sound and its unit of measurement is Watts per square meter (W/m²) or .
How to calculate the sound intensity level?Mathematically, sound intensity level or decibel level can be calculated by using this formula:
[tex]\beta = 10 log(\frac{I}{I_{ref}} )[/tex]
Note: The reference value of sound intensity is equal to 1.0 × 10⁻¹² watts per square inch (W/in²).
Since the intensity of the noise from this motorcycle is 10⁻² W/in², the decibel level (in dB) would be calculated as follows:
Decibel level, β = 10 × log(10⁻²/10⁻¹²)
Decibel level, β = 10 × log(10¹⁰)
Decibel level, β = 10 × 10

A large tree casts a shadow that is 51 feet long. A 6-foot-tall person standing next to the tree casts a shadow that is 4.5 feet long. How tall is the tree?
Answers
Answer:
68 feet tall
Step-by-step explanation:
Imagine the shadows for both the tree and the person are set up like right triangles. The length of their shadows are the bases of the triangles, while the actual heights of the tree and person are the heights of the triangle. We can set up proportions since "height of the person" divided by " their shadow's length" should equal "height of tree" divided by "tree shadow length".
Set up a proportion of the person's high height relative to their shadow's length (which is 6/4.5). Set this equation equal to the tree's proportion (which is x/51).
Solve for x.
[tex]\frac{6}{4.5} = \frac{x}{51}\\Isolate x by multiply 51 to both sides\\\\(306/4.5)=x\\68=x[/tex]
The proportion is solved and the height of the tree is A = 68 feet
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
Now , we can set up the following proportion:
Height of tree / length of tree's shadow = height of person / length of person's shadow
On simplifying , we get
A / 51 = 6 / 4.5
Now we can solve for A by cross-multiplying and simplifying:
A = 51 x 6 / 4.5
A = 68 feet
Therefore, the tree is 68 feet tall
Hence , the proportion is solved

The system of linear equations have no solution
System of Linear EquationThe system of linear equations is the set of two or more linear equations involving the same variables. Here, linear equations can be defined as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. Thus, we can write linear equations with n number of variables.
In the problem, given the system of linear equations are
y = 4/5x - 3 ...eq(i)
y = 4/5x + 1 ...eq(ii)
a) Since there are two unknown variables(x, y) the number of solutions expected is 2.
b)
From equation (i)
y = 4/5x - 3
Put eq(i) into equ(ii)
4/5x - 3 = 4/5x + 1
0 = 4
There's no solution for x and y
In the calculation, there's no solution for both x and y because the variables in both equation are equal to one another and hence cancel out.

What is a linear equation in one variable?
The linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For the first case:
If 2 movies are streamed, the cost is $14 per month
So the cost = number of movies * cost per movie
y = 2*x
14 = 2x
For the second case:
If 6 movies are streamed, the cost is $20 per month
So the cost = number of movies * cost per movie
y = 6*x
20 = 6x
Hence the equation to model the cost 'y' based on the number of movies streamed 'x' would be 14 = 2x and 20 = 6x.

Answers
Answer: y = 1/12x
Step-by-step explanation:
(24, 2)
(12, 1)
find slope (y2 - y1) / (x2 - x1)
2 - 1 / 24 - 12
1 / 12
find y intercept
y = mx + b
1 = 1/12(12) + b
1 = 1 + b
b = 0
y = 1/12x + 0
y = 1/12x
Step by step
First let’s find slope using slope formula
y2 - y1 over x2 - x1
We know the minutes are x
We know the cups of water is y
Points (12, 1) and (24, 2)
2 - 1 over 24 - 12
1 over 12 or 1/12 slope
Now we can write an equation using point slope formula. Y - y1 = m (x - x1) using any set of points, let’s use (12, 1)
y - 1 = 1/12 (x - 12)
y - 1 = 1/2x - 1
Add 1 to both sides to isolate y
y -1 + 1 = 1/12x -1 + 1
y = 1/12x
This is your answer
So your relationship between x and y is
y is equal to 1/12 of x
Let’s check our work
x = 12
1/12 x 12 = 1, so y = 1 when x = 12, this is true according to your chart
x = 24
1/12 x 24 = 2, so y = 2 when x = 24, this is true according to your chart.

The elimination method is the process of eliminating one of the variables in the system of equations using the addition or subtraction methods in conjunction with the multiplication or division of coefficients of the variables.
Therefore,
4x - 7y = 10
3x + 2y = -7
multiply equation(ii) by 3.5
4x - 7y = 10
10.5x - 7y = 24.5
subtract equation(i) from equation(ii)

A spherical ball for a machine was made with a radius of 2 centimeters.
If the ball has a mass of 278.1 grams, which material was used to make the ball?
Copper-8.3 g/cm³
Brass -8.6 g/cm³ Iron - 7.8 g/cm³
Answers
The mass of the ball is 278.1 g, the material used to make the ball must be brass which having density of 8.6 g/cm³.
How to find mass of the ball ?To determine the material used to make the ball, we need to first calculate the volume of the ball.
The volume of a sphere with radius r is given by:
V = (4/3) * π * r^3
Plugging in the given values, we get:
V = (4/3) * π * (2 cm)^3
= (4/3) * π * 8 cm^3
= (4/3) * 8π cm^3
= 32π cm^3
We can then use the density of each material (given in g/cm³) to calculate the mass of the ball if it were made of that material:
Copper: 8.3 g/cm³ * 32π cm³ = 266.4 g
Brass: 8.6 g/cm³ * 32π cm³ = 275.2 g
Iron: 7.8 g/cm³ * 32π cm³ = 250.4 g
Since the mass of the ball is 278.1 g, the material used to make the ball must be brass.
