Step-by-step explanation:

An abscissa is a line that is drawn perpendicular to the vertical axis, or y-axis, of a graph. It is usually measured in the form of a number, and it is used to determine the position of points, lines, and shapes on a graph. Abscissas are also referred to as the x-coordinates of a graph, and they can be used to plot and analyze data.

Quadrants are the four sections of a coordinate plane formed by the intersection of the x-axis and the y-axis. Quadrants are labeled I, II, III, and IV, with Quadrant I being the upper right-hand corner, Quadrant II being the upper left-hand corner, Quadrant III being the lower left-hand corner, and Quadrant IV being the lower right-hand corner. Quadrants are commonly used to graph equations and to identify points on a coordinate plane.

The three points that divide the line segment joining the given points into four equal parts are \((3.5, -1.25)\), \((4, -1.5)\), and \((4.5, -1.75)\)

To find the three points that divide the line segment joining the given points into four equal parts, we can use the Midpoint Formula repeatedly. The Midpoint Formula is given by:

\[ \text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \]

Let's first find the midpoint of the given line segment:

\[ \text{Midpoint} = \left( \frac{3 + 5}{2}, \frac{-1 + (-2)}{2} \right) = \left( 4, -1.5 \right) \]

Now we can use the Midpoint Formula again to find the two other points that divide the line segment into four equal parts. Let's first find the midpoint of the line segment joining the points \((3, -1)\) and \((4, -1.5)\):

\[ \text{Midpoint} = \left( \frac{3 + 4}{2}, \frac{-1 + (-1.5)}{2} \right) = \left( 3.5, -1.25 \right) \]

And then let's find the midpoint of the line segment joining the points \((4, -1.5)\) and \((5, -2)\):

\[ \text{Midpoint} = \left( \frac{4 + 5}{2}, \frac{-1.5 + (-2)}{2} \right) = \left( 4.5, -1.75 \right) \]

So the three points that divide the line segment joining the given points into four equal parts are \((3.5, -1.25)\), \((4, -1.5)\), and \((4.5, -1.75)\).

Answer:

The 6.5% compounded annually would get you the most money. This is because, when compounded annually, the interest is calculated on the original sum plus the interest already earned. Over the four year period, this would result in total interest earned being higher than if the interest was compounded daily, as the interest earned each day would be calculated on the original sum only. For example, with a 6.5% compounded annually rate, at the end of the fourth year you would have a total of $127.82, whereas with a 6.3% compounded daily rate, you would have a total of $126.56

The cost of A Plus Advertising will be less than the cost of Print and More if the number of flyers to be printed and delivered is greater than 160.

Let's assume that the number of flyers to be printed and delivered is "x".

The cost of A Plus Advertising can be represented as:

Cost_A = 0.10x + 24

The cost of Print and More can be represented as:

Cost_P = 0.25x

To find out for how many flyers the cost of A Plus Advertising is less than the cost of Print and More, we need to set up an inequality:

Cost_A < Cost_P

0.10x + 24 < 0.25x

Subtracting 0.10x from both sides, we get:

24 < 0.15x

Dividing both sides by 0.15, we get:

There are 9 possible comparisons that Adnan can write using the temperatures of the three nearby cities.

Combinations are the procedures used in mathematics to pick k things from n different items without replacement.

The following formula computes the combinations of k items from n:

(n, k) = n! / k!×(n-k)!

Let's say that Adnan looks up the current temperature in three nearby cities and writes down their temperatures as T1, T2, and T3.

To compare the temperatures, Adnan can choose any two of the temperatures and write a comparison of them.

Since there are three temperatures, there are a total of three possible pairs of temperatures that Adnan can choose:

1. T1 and T2

2. T1 and T3

3. T2 and T3

For each pair of temperatures, Adnan can write a comparison in one of three ways:

T1 is greater than T2 (T1 > T2)

T1 is less than T2 (T1 < T2)

T1 is equal to T2 (T1 = T2)

So, Adnan can write a total of nine possible comparisons of the temperatures:

T1 > T2,

T1 < T2,

T1 = T2,

T1 > T3,

T1 < T3,

T1 = T3,

T2 > T3,

T2 < T3, and

T2 = T3.

Anika has R283362.97 after 5 years of compound interest. She can use this money to start her bakery.

Anika invested, R180000 at 9.5% compound interest for 5 years. To find out how much money she has now, we need to use the formula for compound interest:

A = P(1 + r)^t

Where A is the final amount, P is the principal amount, r is the annual interest rate, and t is the number of years. Plugging in the values we have:
A = R180000(1 + 0.095)^5
A = R180000(1.095)^5
A = R180000(1.574)

The constant of proportionality for the Amador family is obtained as k = 7.50.

The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional.

If the cost t varies directly with the number of thousand cubic feet of natural gas g used, we can write -

t = kg

where k is the constant of proportionality, which represents the cost per thousand cubic feet of natural gas.

Since the Amador family pays $7.50 per thousand cubic feet of natural gas, we have -

k = 7.50

Therefore, the equation relating the total cost t to the number of thousand cubic feet of natural gas g used is -

t = 7.50g

This means that for every thousand cubic feet of natural gas used, the cost is $7.50.

If the Amador family uses 10,000 cubic feet of natural gas, the total cost would be -

t = 7.50(10) = $75

If they use 20,000 cubic feet of natural gas, the total cost would be -

t = 7.50(20) = $150

Therefore, the COP value is k = 7.50.

Answer:

360 people pledged $25.

Step-by-step explanation:

You'll need to set up only one equation to solve this.

Let's use x for the number of people who pledged $50. Since twice as many people pledged $25, it would be 2x. Keep this in mind for later.

Multiply 2x by 25, and you should get 50x. Now, your equation is 50x + 50x = 18,000. Simplify this to 100x = 18,000.

Now, divide both sides by 100. After doing so, you should have x = 180. This is how many people pledged $50. To find how many pledged $25, plug the value of x into 2x. (In other words, multiply 180 by 2.) After doing so, you should get 360. This is how many people pledged $25.

The answer to the equation cos195°cos285° is -1/4.

An equation is a mathematical statement that asserts the equality of two expressions. Equations are used to describe relationships between different quantities and can be used to solve for unknown values. Equations are typically written as symbols, but can also be written in words. Simple equations might involve addition, subtraction, multiplication, and division, while more complex equations may involve exponents, logarithms, and trigonometric functions. Equations can be used to model and understand real-world phenomena, such as calculating projectile motion, or predicting the behavior of a chemical reaction.

This is derived from the trigonometric identity cos{60°−x}cosx – sin(60°−x)sinx. This identity states that the cosine of the sum of two angles is equal to the product of the cosines of each angle minus the product of the sines of each angle.

By substituting the angles 195° and 285° into the identity, we get cos{60°−195°}cos195° – sin(60°−195°)sinx. When we use the values of the angles, we get cos{-135°}cos195° – sin(135°)sinx. We can then simplify this to -1/4cos195° – 0sinx. As the sine of the angle is 0, this simplifies to –1/4cos195°. As the cosine of 195° is -1/4, the answer to the equation cos195°cos285° is -1/4.

The areas of every basic shape can be added together to determine the area of the composite shapes. Simply calculate each shape's area separately, then put them together to get the area of composite shapes.

Now in the question, we have 2 triangles with base, b =31mm and height, h = 14mm

Now area of both the triangles = 2 × 1/2 × b × h

The eigen values of the matrix A are 2, -2, and 7, and the corresponding eigen vectors are [1,1,2], [1,-2,0], and [2,1,1].

To find the eigen values and eigen vectors of the matrix A=([2,2,0],[2,1,1],[-7,2,-3]), we first need to find the characteristic equation of the matrix. This is done by finding the determinant of (A-λI), where λ is the eigenvalue and I is the identity matrix.

The characteristic equation is:
|A-λI| = |[2-λ,2,0],[2,1-λ,1],[-7,2,-3-λ]| = 0

Expanding the determinant, we get:
(2-λ)((1-λ)(-3-λ)-2) - 2(2(-3-λ)+7) + 0 = 0

Simplifying the equation, we get:
-λ³ + 6λ² - 5λ - 14 = 0

The eigen values are the roots of this equation. We can use the rational root theorem to find the possible rational roots of the equation, which are ±1, ±2, ±7, and ±14. By testing these values, we find that the eigen values are λ=2, λ=-2, and λ=7.

Now, we can find the eigen vectors by plugging the eigen values back into the equation (A-λI)v=0, where v is the eigen vector.

For λ=2, we get:
([2-2,2,0],[2,1-2,1],[-7,2,-3-2])v = 0
([0,2,0],[2,-1,1],[-7,2,-5])v = 0

The eigen vector for λ=2 is v = [1,1,2].

For λ=-2, we get:
([2+2,2,0],[2,1+2,1],[-7,2,-3+2])v = 0
([4,2,0],[2,3,1],[-7,2,-1])v = 0

The eigen vector for λ=-2 is v = [1,-2,0].

For λ=7, we get:
([2-7,2,0],[2,1-7,1],[-7,2,-3-7])v = 0
([-5,2,0],[2,-6,1],[-7,2,-10])v = 0

The eigen vector for λ=7 is v = [2,1,1].
