The rectangular coordinates for (4.5, -30 degrees) are (3.9, -2.3), which is option B.
What is rectangle ?
A rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle.
To find the rectangular coordinates for a point in a plane given its polar coordinates, use the following formula:
x = r * cos(θ)
y = r * sin(θ)
Where (r, θ) are the polar coordinates and (x, y) are the rectangular coordinates.
For the point (4.5, -30 degrees), have:
r = 4.5
θ = -30 degrees = -30 * (π / 180) radians
x = r * cos(θ) = 4.5 * cos(-30 * (π / 180)) = 3.9
y = r * sin(θ) = 4.5 * sin(-30 * (π / 180)) = -2.3
So, the rectangular coordinates for (4.5, -30 degrees) are (3.9, -2.3), which is option B.

The rectangular coordinates for (4. 5, -30 degrees) are (3.9, -2.3).
The rectangular coordinates for (4.5, -30 degrees) can be found using the following formula:
x = r * cos(θ)
y = r * sin(θ)
where r is the magnitude (or distance from the origin) and θ is the angle in radians.
In this case, r = 4.5 and θ = -30 degrees = -30 * (π/180) radians.
So:
x = 4.5 * cos(-30 * (π/180)) = 4.5 * cos(-π/6) = 4.5 * sqrt(3)/2
y = 4.5 * sin(-30 * (π/180)) = 4.5 * sin(-π/6) = -4.5 / 2
Therefore, the rectangular coordinates are (x, y) = (4.5 * sqrt(3)/2, -4.5 / 2), which is approximately (3.9, -2.3).
Option B (3.9, -2.3) is the right response as a result.

Which rational function has a horizontal asymptote of y=0?
y = [tex]\dfrac{ x + 8}{x^2 + 3x + 2}[/tex] is the rational function that has a horizontal asymptote of y = 0.
What is rational function?When the denominator of a polynomial has a degree of at least 1, it is said to be a rational function. Or to put it another way, the denominator must contain a variable.
When p(x) and q(x) are polynomials and q(x) ≠ 0, the general form of a rational function is p(x)/q(x).
Asymptotes are lines that the function graph approaches but never crosses. Both the x and y axes are asymptotes in the parent function f(x)=1x. The parent function's graph will approach the asymptotes steadily but never actually touch them.
If the degree of the denominator > degree of the numerator, there is a horizontal asymptote at y = 0.
Here, only y = [tex]\dfrac{ x + 8}{x^2 + 3x + 2}[/tex] has the degree of the denominator > degree of the numerator.
Thus, y = [tex]\dfrac{ x + 8}{x^2 + 3x + 2}[/tex] is the rational function that has a horizontal asymptote of y = 0.

How do you find the distance between two places?.
The distance between two places cab be found using distance formula if you know the coordinates of the places.
The distance formula is a mathematical equation that can be used to find the distance between two points in a two-dimensional or three-dimensional space. The formula is as follows:
Distance = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²)
Where x₁, y₁, and z₁ are the coordinates of the first point and x₂, y₂, and z₂ are the coordinates of the second point. The formula is based on the Pythagorean theorem, which states that the square of the distance between two points is equal to the sum of the squares of the differences in their coordinates.
For example, if you have the coordinates of two places on a map, you can use the distance formula to calculate the distance between them. Let's say the coordinates of place A are (x₁, y₁) = (4, 5) and the coordinates of place B are (x₂, y₂) = (9, 12). The distance between place A and place B would be:
Distance = √((x₂ - x₁)² + (y₂ - y₁)²)
= √((9 - 4)² + (12 - 5)²)
= √(5² + 7²)
= √(25 + 49)
= √(74)

Triangle ABC and triangle DEF are not congruent.
What does a math congruent mean?
Congruent refers to things that are exactly the same size and shape. Even if we flip, turn, or rotate the forms, the shape and size should remain the same.
The measure of angle A and angle D are both 40 degrees, but the measure of angle B and angle F are not equal. The measure of angle B is 20 degrees, while the measure of angle F is 120 degrees.
In a triangle, the sum of all three angles is 180 degrees. So in triangle ABC, the measure of angle C is 180-40-20 = 120 degrees.
In triangle DEF, the measure of angle E is 180-40-120 = 20 degrees.
Therefore, angle B and angle E are not congruent, so the triangles are not congruent.
In order for two triangles to be congruent, they must have corresponding sides and angles of the same measure. Since the measure of angle B and angle E are not equal, then triangle ABC and triangle DEF are not congruent.

You want to buy a house for 300,000 and pay 20% down. How much is your down payment? Calculate the principal for the home loan after the down payment. The bank tells you the total interest for the loan will be $232200 over 30 years. Calculate the total amount owed to the bank including principal and interest. Calculate the monthly payment for a 30 year mortgage. Calculate the total monthly cost including another 300 per month for taxes and 150 per month for insurance.
Principal, P = $ 300,000
Rate, R = 20%
Time, T = 30 years
The down payment would be 300,000 x 20% = $60,000.
The principal for the home loan after the down payment would be 300,000 - 60,000 = $240,000.
The total amount owed to the bank including principal and interest would be 240,000 + 232200 = $462200.
To calculate the monthly payment for a 30 year mortgage, you would use the formula:
(principal + interest) / (number of months in 30 years)
which would be ($462200) / (360 months) = $1283.33
To calculate the total monthly cost including another 300 per month for taxes and 150 per month for insurance, you would add the mortgage payment to the additional costs:

Gallons of gas used 40 gallons.
The given equation, m = pace / 40g, represents the distance in miles (m) that a car can travel using a certain number of gallons (g) of gas. The variable "pace" represents the miles per gallon (mpg) of the car. To find the number of gallons used, we need to solve for g in the equation.
Here are the key steps:
First, we can rearrange the equation to find the mpg: mpg = pace/g.Next, we can substitute the given information, that the car has gone 140 miles, into the equation: 140 miles = pace/g.To find the number of gallons used, we can divide both sides of the equation by pace: g = 140 miles/pace.The value of pace is not given but we know that m = pace / 40g. So we can use this information to find the value of pace.We can substitute the value of m = 140 miles into m = pace / 40g, to find the value of pace.Now we can substitute the value of pace into the equation g = 140 miles/pace.Finally, we can solve for g and we get the answer that the car used 40 gallons of gas.

Square E has sides of length e cm.
Square F has sides of length f cm.
The area of square E is 44% greater than the area of square F.
Work out the ratio e:f
The ratio of e:f from 2 different squares are 1.2:1.
From the case, we have 2 squares that:
Square E side = e
Square F side = f
Area of E = (1 + 44%) Area of F
Using the area of square formula, we know that:
Area of square = side x side
Area of square = side²
Area of E = e x e
Area of E = e²
Area of F = f x f
Area of F = f²
We will compare the area of both squares:
Area of E = (1 + 44%)Area of F
e² = (1 + 44%) f²
e² = 1.44 f²
√e² = √(1.44 f²)
e = 1.2 f
Hence the ratio of e : f would be:
e : f = 1.2f : f
e : f = 1.2 : 1

What is the difference between true solution and colloidal solution Class 9?.
The main difference between a true solution and a colloidal solution is the particle size of the dispersed substance. In a true solution, the particles are so small that they cannot be seen with the human eye, while in a colloidal solution, the particles are intermediate in size and are visible under microscope.
A true solution is a homogeneous mixture of two or more substances where one substance is completely dissolved in the other. The particles of the dissolved substance, called solute, are so small that they cannot be seen with the human eye and are evenly distributed throughout the solution. A true solution is transparent, and the particles of the dissolved substance do not scatter light, thus not visible under a microscope. Examples of true solutions are sugar dissolved in water, and salt dissolved in water.
On the other hand, a colloidal solution is a type of mixture where one substance is dispersed throughout another substance in small particles that are not large enough to settle out but are large enough to scatter light. The particles of the dispersed substance, called the dispersed phase, are intermediate in size between those of a true solution and a suspension. The particles are visible under microscope, but not to the human eye, and the mixture is usually cloudy or opaque. Examples of colloidal solutions are milk, fog, and blood.

In the statement "If AB ≅ DE, EF ≅ DE, then AB ≅ EF," AB is congruent to DE, and EF is congruent to DE, so AB must also be congruent to EF according to the transitive property.
The other properties you listed are not applicable in this case. The symmetric property states that if A is congruent to B, then B is congruent to A. The reflexive property states that every object is congruent to itself. And multiplication is not a property of congruence.

you are skiing on a mountain with an altitude of 12 meters. the angle of depression is 21 degrees. about how far do you ski down the mountain
When you are skiing on a mountain with an altitude 12 meters and angle of depression is 21 degrees then you will ski down for a distance of 31.57 meters.
Solution:
Here we have ,
Height i.e altitude of mountain (h) = 12 meters
Angle of depression (∅) =21°
And let the distance coverd be (b)
Using theorm of trigonometery,
tan∅ = [tex]\frac{height}{base}[/tex]
= [tex]\frac{12}{b}[/tex]
Therefore,
tan(21°) = [tex]\frac{12}{b}[/tex]
b = [tex]\frac{12}{tan(21)}[/tex]
b = [tex]\frac{12}{0.38}[/tex]
b = 31.57 meters
Hence ,
You will ski down 31.57 meters.

The equivalent expressions are
(3x² + 21x + 18) / (x² - 7x - 8)
3 (x + 6) (x + 1) / (x + 1) (x - 8)
Options A and E are the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(3x² + 21x + 18) . x² - 7x - [tex]8)^{-1}[/tex]
This can be written as,
(3x² + 21x + 18) / (x² - 7x - 8) ______(A)
Now,
Solve for (3x² + 21x + 18).
(3x² + 21x + 18)
3 (x² + 7x + 6)
3 (x² + (6 + 1)x + 6)
3 (x² + 6x + x + 6)
3 (x (x + 6) + 1 (x + 6))
3 (x + 6) (x + 1)
Solve for (x² - 7x - 8).
x² - (8 - 1)x - 8
x² - 8x + x - 8
x (x - 8) + 1 (x - 8)
(x + 1) (x - 8)
Now,
(3x² + 21x + 18) / (x² - 7x - 8)
= 3 (x + 6) (x + 1) / (x + 1) (x - 8) _____(B)
Thus,
From (A) and (B),
(3x² + 21x + 18) / (x² - 7x - 8) and 3 (x + 6) (x + 1) / (x + 1) (x - 8) are the equivalent expressions.

The data show the number of free throws attempted by a
team in its first ten games.
{2,11,11,11,12,12,13,14,14,15}
The median is 12 attempts and the mean is 11.5
attempts.
After reviewing the data, it is determined that 2 should not
be included, since that was an exhibition game rather
than a regular game during the season.
What is the new mean if '2 attempts' is removed from the
data set?

Submit
The new mean of the data-set, with the observation 2 removed, is given as follows:
12.67 attempts.
How to obtain the mean of a data-set?The mean of a data-set is obtained as the sum of all observations in the data-set divided by the number of observations.
Removing the observation 2, the data-set is given as follows:
11, 11, 11, 12, 13, 13, 14, 14, 15.
The sum of all these observations is given as follows:
3 x 11 + 12 + 2 x 13 + 2 x 14 + 15 = 114.
There are nine observations, hence the mean of these observations is given as follows:
114/9 = 12.67.
