Answer:
It is the one on the bottom right
Step-by-step explanation:
First of all, we have to start at (0,0), so we can cross out the one on the top left and top right, as they does not.
Also, the one on the bottom right does not go back to the ground, though just stays in the air, but the one on the bottom right dows go back to the ground.
So, its the one on the bottom right

Is the absolute value of a complex number real?
The absolute value of a complex number is real.
The absolute value of a complex number is also known as its magnitude. It is a non-negative scalar quantity that represents the distance of the complex number from the origin in the complex plane.
The absolute value of a complex number is represented by the symbol "|z|" where z is the complex number.
The absolute value of a complex number is always a real number. For example, the absolute value of the complex number 4 + 3i is 5 (the distance of this point from the origin), which is a real number.

Which of the following equations have an -intercept of (-2, 0) and y-intercept of (0, 3)?
Select all that apply.
y=3/2x+3
y=3x-2
2y-3x=6
y=-2x+3
y-1=-2(x+3)
Answer:
The first and third choices
[tex]y = \dfrac{3}{2}x + 3[/tex]
and
[tex]2y-3x=6[/tex]
Step-by-step explanation:
(I cannot properly see the leading negative signs in choices 4 and 5, I copied/pasted your question choices from Brainly post and zoomed)
First understand what x and y intercepts are
The y-intercept is the value of y where the graph of the equation crosses the y-axis, It is the value of y when x = 0
The x-intercept is the value of x where the graph of the equation crosses the x-axis, It is the value of x when y = 0
We are given that the x-intercept is (-2, 0) and y = (0,3)
We can use a process of elimination to get rid of obviously incorrect choices and then work on the possible correct ones depending on whether we come up with the correct values of y first and eliminating those that do not match x =0, y =3 or (0,3) and then see if the x-intercept is (-2,0)
First choice let's find the y-intercept for the first choicethe perimiter of a rectangle is 30 inches. if its length is three times its width, find the dimensions
The answer is l = 3.75 and l = 11.25.
Given the length l and width w of a rectangle, its perimeter is:
P=2(l+w)
This formula can be used to form an equation as we already know the value of P.
So, Let the width be w. The length will be 3w. As the perimeter is 30 inches, the width can be found as follows.
2(w+3w)=30
4w=15
w=3.75
Thus, the width is 3.75 inches. The length will be 3*3.75=11.25 inches.
Steps:
Step 1: Let the width of the rectangle be w. Step 2: Since the length is 3 times the width, the length of the rectangle is 3w. Step 3: The perimeter of the rectangle is 30 inches. Step 4: We can write the formula for the perimeter of the rectangle as 2w + 2(3w) = 30. Step 5: Solve for w, then we get w = 3.75Step 6: therefore l = 3w = 3.75 * 3 = 11.25.To know about the Parameters of Rectangle:

What is the formula of a triangular method?
The formula for a triangular method is: (x1 + x2 + x3) / 3
1. The triangular method is the average of three different values: x1, x2, and x3.
2. To calculate the average, add the three values together and divide by three.
3. The formula for a triangular method is therefore (x1 + x2 + x3) / 3.
The triangular method is a method used to calculate an average of three different values. This method is most useful when there is not enough information available to calculate a more accurate average. To calculate an average using the triangular method, the three values (x1, x2, and x3) are added together and then divided by three. The formula for a triangular method is (x1 + x2 + x3) / 3. This method is useful for finding an average when a more accurate average cannot be calculated due to a lack of data. It is also used when data points are not necessarily related, as the triangular method is less affected by outliers than other methods of calculating an average. The triangular method is a quick and easy way to find an average when more complex calculations are not possible.

Considering the expression of a line, the equation of the line that passes through the points (-6,1) and (6,7) is y=1/2x +4.
What is a linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin.Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope can be calculated using:
m= (y₂ - y₁)÷ (x₂ - x₁)
Substituting the value of the slope and the value of one of the points in y= mx + b, the value of the ordinate to the origin b can be calculated.
Equation in this caseIn this case, being (x₁, y₁)= (-6, 1) and (x₂, y₂)= (6,7), the slope can be calculated as:
m= (7 -1)÷ (6 -(-6))
m= (7 -1)÷ (6 +6)
m= 6÷ 12
m= 1/2
Considering point 2 and the slope m, you obtain:

Answer:
C. f(x) = (x - 3)² + 4
Step-by-step explanation:
Given parent function:
[tex]f(x)=x^2[/tex]
When a graph is translated "a" units right, subtract "a" from the x-value of the function.
Therefore, the translation of the parent function 3 units right is:
[tex]\implies f(x-3)=(x-3)^2[/tex]
When a graph is translated "a" units up, add "a" to the function.
Therefore, the translation of the function 4 units up is:

Gwen can a photo that i 4inche wide by 6 inche long into her computer. If he cale the length down to 3inche how wide hould the imilar photo be?
The width of a similar photo will be 2 inches.
As per the given problem,
Width of original photo = 4 inches
Height of original photo = 6 inches
After scaling the photo,
Height of new photo = 3 inches.
Let’s understand about scale factor.
An amount that multiplies (or "scales") a quantity is called a scale factor.
Scale factor = height of the sized image/size of the original image.
Scale factor = 3/6 = 1/2.
Therefore, the scaled image's width = scale factor *the size of the original image.
The width of the scaled photo = (½)*4 = 2.

What are complementary angles?Two angles are defined as complementary is the sum of their measures is of 90º.
The variables that represent each angle in this problem are given as follows:

They are complementary angles, hence:
x + y = 90.
The difference between four times the measure of the smaller angle and the measure of the larger angle is 10, hence:

Step-by-step explanation:
This is a particularly tough question. It involves polynomial division(a real laborious process) and solving using quadratic formula.
I presume your school has provided you the resources for both.
Anyways, here goes a brief explanation
To find the roots(zeros) of a polynomial, [tex]f(x)[/tex] , set [tex]f(x) = 0[/tex] and solve for values of [tex]x[/tex]
In general, if [tex]a[/tex] is a zero of [tex]f(x)[/tex], then [tex]f(x) \div(x-a)[/tex] will leave no remainder. In other words, it is a factor of the polynomial. It also means [tex]x - a = 0[/tex]
The given polynomial is [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex]
We are given that [tex]- 2[/tex] is a zero of [tex]f(x)[/tex]. This simply means that [tex]f(-2) = 0[/tex]
Plugging [tex]-2[/tex] into the function gives
[tex]f(-2) = 4(-2)^3 -15(-2)^2 - 31x + 30\\\\ = 0 =4\left(-8\right)-15\cdot \:4-31\left(-2\right)+30[/tex]
Which indeed is 0
Here [tex]a = -2[/tex] , so [tex]x - (-2)[/tex] which is [tex]x + 2[/tex] is a factor of[tex]f(x)[/tex]. It also means that
[tex]x-(-2) = 0 \;or\; x + 2 = 0[/tex]
Steps to factor the polynomial [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex] :
Divide [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex] by [tex]x+2[/tex]Multiplying both sides of the above by [tex]4[/tex] gives [tex]4x -3 = 0.[/tex] So [tex]4x-3[/tex] is the third factor, replacing [tex]x - \dfrac{3}{4}[/tex]
The factors of [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex]

What is the graph of a function?
The graph of a function is a visual representation of the relationship between the input values (x-coordinates) and the output values (y-coordinates) of the function. In other words, it is a visual representation of the function's rule.
The graph of a function can take many different forms, depending on the function's rule. Linear functions, for example, will produce a straight line on the graph.
i) 2y - 4x < 8 can be solved by adding 4x to both sides and then dividing by 2, giving:
y < 2x + 4.
ii) -4y > -x + 12 can be solved by adding x to both sides and then dividing by -4, giving: y < x/4 - 3.
iii) | x + 3 | = y, you can split this into two cases:
i. x + 3 = y
ii. -(x + 3) = y
iv) |2x – 6| + 2 = y, you can split this into two cases:
i. 2x - 6 + 2 = y
ii. -(2x - 6) + 2 = y
We can use these equations to plot the graph on a coordinate plane.
Hence, the solution is the set of all points (x,y) that satisfy the inequalities:
y < 2x + 4, y < x/4 - 3, x + 3 = y, and 2x - 6 + 2 = y.
