What is CP means ? Can anyone help me

Answers

Answer 1
Answer:

Cost Price :

The cost price of an item is the sum paid to acquire it or the cost at which it was produced. The cost price is denoted by the letter C.P. 

Step-by-step explanation:

we made money when we sold a product we used the formula are :

The Formula for Cost Price (CP) : Selling Price (SP) - Profit

we lose money while selling a product. we used formula are :

The Formula for Cost Price (CP) : Selling Price (SP) + Loss

The profit (gain) percentage and selling price are :

The Formula for Cost Price(CP) : {100/(100 + Profit %)} x SP.

The loss percentage and SP are :

The Formula for Cost Price(CP) : {100/(100 - Loss %)} x SP

Know more:

By comparing the profit to the selling price the CP is used to confirm the profit. This implies that there is a profit in the purchase if the original value, which is the C.P.is lower than the selling price.

Additionally the purchase will result in a loss if the C.P. is higher than the S.P.

How to define the composite function of f(x) and g(x)?

The composite function of f(x) and g(x) is given by the equation with rile presented as follows:

(f ∘ g)(x) = f(g(x)).

For the composition of two functions, we have that the output of the inner function, which for this example is g(x), serves as the input of the outer function, which for this example is f(x).

Hence the functions are given as follows:

u(w(x)) = u(-2x²) = -(-2x²) + 1 = 2x² + 1. w(u(x)) = w(-x + 1) = -2(-x + 1)².

At x = 3, the numeric values are given as follows:

Find the missing value of 15,17,___,28,39:mean 23

Answers

Step-by-step explanation:

The sum of the given numbers is:

15 + 17 + x + 28 + 39 = 99 + x

To find the missing value, we can use the formula for the mean (average):

mean = (sum of numbers) / (number of numbers)

Substituting the given values:

23 = (15 + 17 + x + 28 + 39) / 5

Multiplying both sides by 5:

115 = 15 + 17 + x + 28 + 39

Simplifying:

x + 99 = 115

x = 16

Therefore, the missing value is 16.

Suppose that a town has 5000 people and that you want to pick a systematic sample of size n = 10 at random. Explain and illustrate how you will choose this sample. (10 points)

Answers

The sample space will be 243, 743, 1243, 1743, 2243, 2743, 3243, 3743, 4243, and 4743.

What exactly is a sample space?

A sample space is the collection of all potential results of a random experiment or process in probability theory. It's represented by the symbol (the uppercase Greek letter omega).

For instance, if we flip a fair coin, the sample space is H, T, where H stands for the outcome of a heads result and T stands for a tails result. The sample space on a normal six-sided dice is 1, 2, 3, 4, 5, and 6.

No matter how likely they are, all outcomes are included in the sample area. In order to accurately estimate the probability of an event, the sample space must be defined.

Now,

To choose a systematic sample of size n = 10 from a town with 5000 people, we will use a systematic sampling technique. Here are the steps to follow:

Determine the sampling interval: The sampling interval is the number of people in the population divided by the desired sample size. In this case, the sampling interval is 5000/10 = 500.

Select a random starting point: To ensure the sample is representative of the population, we need to select a random starting point between 1 and 500.

We can use a random number generator to choose a starting point. Suppose we choose the number 243 as our starting point.

Select every nth person: Starting from the chosen starting point, we will select every 500th person until we reach a sample size of 10.

So, we will select people with the following index numbers: 243, 743, 1243, 1743, 2243, 2743, 3243, 3743, 4243, and 4743.

What is the distance between Points E and H ? Round to the nearest tenth.

Answers

The distance between points D(1,3) and H(9,8) found using the distance formula is 9.43 units.

What is the distance formula?

To find the distance between two points, the coordinates of two points in space are used in the formula. In coordinate geometry, a two-dimensional or three-dimensional space can be used to calculate the distance between two points using the distance formula. The Pythagoras theorem is sometimes used to calculate the distance between two places. The length of the line segment bridging two points on a plane is known as the distance between the points.

d=√((x2 - x1)² + (y2 - y1)²) is a common formula to calculate the distance between two points. This equation can be used to calculate the separation between any two locations on an x-y plane or coordinate plane.

Assuming the question is the one given below.

The points given are:

D = (1,3) = (x1,y1)

H = (9,8) = (x2,y2)

The distance D between these two points can be found using the distance formula.

D = [tex]\sqrt{{(x_2-x_1)}^2 + {(y_2-y_1)}^2 } = \sqrt{{(9-1)}^2 + {(8-3)}^2 }[/tex] = √89 = 9.43 units

Answers

Answer:

The answer that you are looking for is 70º

Step-by-step explanation:

Usually, in three-sided figures, there is a total of 3 angles all adding up to 180º.

So in turn, since most quadrilaterals are made up of 2 triangles all the sides have to equal to 360º.

We can use the equation 360 = 110×2+q2

To find the value of q.

The First step to do is to simplify all terms with 110×2 being equal to 220 and q2 staying the same.

We then use the opposite symbol to remove 220 leaving q2 by itself while 360 is subtracted by 220 and turned into 140.

The only thing left to do is to do the opposite operation of multiplying, which is dividing and dividing both sides by 2 leaving q = 70.

You can find the equation below:
360 =  110×2+q2
360 =  220 + q2
-220 = -220 + q2
 140 = q2
  ÷2 = ÷2
  70 = q

The following graph shows three of the four vertices of rectangle WXYZ

Write the ordered pair that represents the location of point Z.

Answers

For the given rectangle, the ordered pair that represents the location of point Z is (11,6).

What is a rectangle?

The internal angles of a rectangle, which has four sides, are all precisely 90 degrees. The two sides come together at a straight angle at each corner or vertex. The rectangle differs from a square because its two opposite sides are of equal length. Also, it is known as an equiangular quadrilateral. Rectangles can also be referred to as parallelograms because their opposite sides are equal and parallel. A rectangle's diagonals cut each other in half. It has four right angles and is a parallelogram. The complete distance that the rectangle's outside boundary covers is referred to as its perimeter. The area a two-dimensional form occupies in a plane is known as its area. It has a square unit of measurement. As a result, the rectangle's area is the space enclosed by its exterior lines. It is the same as the length times the width calculation.

The rectangle should have opposite sides of equal length.

Here,

XY = WZ

XW = YZ

From the graph, we can write the coordinates as:

X = (7,11)

Y = (11,11)

W = (7,6)

Point Z should lie directly below Y so that it is in a straight vertical line.

Then it should have the same x coordinate as Y.

It should also lie in the same horizontal line that passes through W.

So it will have the same y coordinate as W.

Therefore for the given rectangle, the ordered pair that represents the location of point Z is (11,6).

When twο quantities are prοpοrtiοnal, their relatiοnship stays cοnsistent οver time. Tο put it anοther way, if twο variables, A and B, are prοpοrtiοnal, then the ratiο οf A tο B must be cοnstant and can be written as fοllοws:

where k is a ratiο cοnstant. This means that tο keep the ratiο cοnsistent, if οne οf the quantities is multiplied by a certain factοr, the οther quantity must alsο be multiplied by the same factοr.

where T is the οbject's temperature, Ts is the envirοnment's temperature, and k is a prοpοrtiοnality factοr. dT/dt stands fοr the rate οf change οf temperature.

In this instance, the rοοm is currently 70°F and the pοt οf water is οriginally 200°F. We thus have:

dT/dt = -k (200 - 70) = -k(130) (130)

-5k = ln(0.82) (0.82)

k = -ln(0.82)/5

Answers

The area of the triangle is approximately 1.987 square units.

What are the properties of Triangle?

The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

Using sin rule of a triangle,

[tex]\frac{Sin A}{a} = \frac{Sin C}{c} = \frac{Sin B}{b}[/tex]

In our case,

[tex]\frac{Sin 18}{1.6} = \frac{Sin Q}{4.2} = \frac{Sin P}{QR}[/tex]

From equation 1

[tex]\frac{Sin 18}{1.6} = \frac{Sin Q}{4.2} \\\frac{(Sin 18)*4.2}{1.6} = {Sin Q}\\Sin \ Q =21/8* sin\ 18\\[/tex]

Thus,

∠Q = 125.79 degrees

since sum of all angles is 180 degrees

so,

∠P = 180-125.79-18

∠P = 36.21

So From the equation 1

[tex]\frac{Sin 18}{1.6} = \frac{Sin P}{QR}\\\frac{Sin 18}{1.6} = \frac{Sin 36.2}{QR}\\QR = \frac{Sin 36.2}{\frac{Sin 18}{1.6}}[/tex]

QR = 3.06 cm

To find the area of the triangle, we can use Heron's formula:

Area = √(s(s-a)(s-b)(s-c))

where a, b, and c are the side lengths and s is the semi perimeter:

s = (a + b + c)/2

Plugging in the values we get:

s = (4.2 + 1.6 + 3.052)/2

s ≈ 4.426

Now we can use Heron's formula:

Area = √(4.426(4.426-4.2)(4.426-1.6)(4.426-3.052))

Using a calculator, we find:

Area ≈ 1.987 square units

Therefore, the area of the triangle is approximately 1.987 square units.

Answer:

The slope of the tangent line to the curve at the given point is -11/7.

Step-by-step explanation:

Differentiation is an algebraic process that finds the gradient (slope) of a curve.  At a point, the gradient of a curve is the same as the gradient of the tangent line to the curve at that point.

Given function:

[tex]4x^2+5xy+y^4=370[/tex]

To differentiate an equation that contains a mixture of x and y terms, use implicit differentiation.

Begin by placing d/dx in front of each term of the equation:

[tex]\dfrac{\text{d}}{\text{d}x}4x^2+\dfrac{\text{d}}{\text{d}x}5xy+\dfrac{\text{d}}{\text{d}x}y^4=\dfrac{\text{d}}{\text{d}x}370[/tex]

Differentiate the terms in x only (and constant terms):

[tex]\implies 8x+\dfrac{\text{d}}{\text{d}x}5xy+\dfrac{\text{d}}{\text{d}x}y^4=0[/tex]

Use the chain rule to differentiate terms in y only. In practice, this means differentiate with respect to y, and place dy/dx at the end:

[tex]\implies 8x+\dfrac{\text{d}}{\text{d}x}5xy+4y^3\dfrac{\text{d}y}{\text{d}x}=0[/tex]

Use the product rule to differentiate terms in both x and y.

[tex]\boxed{\dfrac{\text{d}}{\text{d}x}u(x)v(y)=u(x)\dfrac{\text{d}}{\text{d}x}v(y)+v(y)\dfrac{\text{d}}{\text{d}x}u(x)}[/tex]

[tex]\implies 8x+\left(5x\dfrac{\text{d}}{\text{d}x}y+y\dfrac{\text{d}}{\text{d}x}5x\right)+4y^3\dfrac{\text{d}y}{\text{d}x}=0[/tex]

[tex]\implies 8x+5x\dfrac{\text{d}y}{\text{d}x}+5y+4y^3\dfrac{\text{d}y}{\text{d}x}=0[/tex]

Rearrange the resulting equation in x, y and dy/dx to make dy/dx the subject:

[tex]\implies 5x\dfrac{\text{d}y}{\text{d}x}+4y^3\dfrac{\text{d}y}{\text{d}x}=-8x-5y[/tex]

[tex]\implies \dfrac{\text{d}y}{\text{d}x}(5x+4y^3)=-8x-5y[/tex]

[tex]\implies \dfrac{\text{d}y}{\text{d}x}=\dfrac{-8x-5y}{5x+4y^3}[/tex]

To find the slope of the tangent line at the point (-9, -1), substitute x = -9 and y = -1 into the differentiated equation:

[tex]\implies \dfrac{\text{d}y}{\text{d}x}=\dfrac{-8(-9)-5(-1)}{5(-9)+4(-1)^3}[/tex]

[tex]\implies \dfrac{\text{d}y}{\text{d}x}=\dfrac{72+5}{-45-4}[/tex]

[tex]\implies \dfrac{\text{d}y}{\text{d}x}=-\dfrac{77}{49}[/tex]

[tex]\implies \dfrac{\text{d}y}{\text{d}x}=-\dfrac{11}{7}[/tex]

Therefore, slope of the tangent line to the curve at the given point is -11/7.

area of canvas 2 1/2 x 3 1/4

Answers

The area of the canvas is 8 1/8 square units.

The area of a canvas with dimensions of 2 1/2 x 3 1/4 can be calculated by multiplying the length by the breadth.

2 1/2 and 3 1/4 must first be converted into improper fractions:

2 1/2 = (2 x 2 + 1) / 2 = 5/2

3 1/4 = (3 x 4 + 1) / 4 = 13/4

The area may now be calculated by multiplying the two fractions:

(5/2) x (13/4) = (5 x 13) / (2 x 4) = 65/8

The canvas's surface area is 65/8 square units as a result. This can be expressed as a mixed number as well:

65/8 = 8 1/8

Hence, the canvas has an area of 8 1/8 square units.

Polygon JKLM is drawn with vertices J(−2, −5), K(−4, 0), L(−1, 2), M (0, −1). Determine the image coordinates of L′ if the preimage is translated 9 units up.

L′(7, 2)
L′(−1, 11)
L′(−13, 2)
L′(−1, −9)

Answers

Answer:

the correct option is: L′(-1, 11).

Step-by-step explanation:

To translate the preimage 9 units up, we need to add 9 to the y-coordinate of each vertex of the polygon. Thus, the image of polygon JKLM after the translation will have vertices J′(−2, 4), K′(−4, 9), L′(−1, 11), M′(0, 8). Therefore, the image coordinates of L′ are (-1, 11).

After translation the image coordinates of L' is (-1, 11). Therefore, option B is the correct answer.

Given that, Polygon JKLM is drawn with vertices J(-2, -5), K(-4, 0), L(-1, 2), M (0, -1).

When the shape is moved up by k units, then replace y with y + k.

The translation is as follows:

Here, J(-2, -5) → (-2, -5+9) → J'(-2, 4)

K(-4, 0) → (-4, 0+9) → K'(-4, 9)

L(-1, 2) → (-1, 2+9) → (-1, 11)

M(0, -1) → (0, -1+9) → (0, 8)

Therefore, option B is the correct answer.

Solve this composite function:

Answers

According to the given composite function the correct answer is , (g o h)[tex](n/2) = 8n^2 + 42n + 35.[/tex]

What is a composite function?

A composite function is a function that is formed by combining two or more functions. It is obtained by taking the output of one function and using it as the input of another function.

Suppose we have two functions, f(x) and g(x). The composite function of f and g, denoted by f o g, is defined as:

(f o g)(x) = f(g(x))

In words, this means that we apply the function g to the input x, and then we apply the function f to the output of g. The result is a new function that combines the effects of both f and g.

For example, if we have [tex]f(x) = x^2[/tex] and g(x) = 2x + 1, then the composite function f o g is:

[tex](f o g)(x) = f(g(x)) = f(2x + 1) = (2x + 1)^2 = 4x^2 + 4x + 1[/tex]

The composite function f o g takes an input x, applies g to it to get 2x + 1, and then applies f to that to get [tex]4x^2 + 4x + 1[/tex] as the final output.

To compute (g o h)(n/2), we need to first evaluate h(n/2) and then substitute the result into g(n) in place of n.

So, first we evaluate h(n/2):

h(n/2) = 4(n/2) + 5 = 2n + 5

Now we substitute this expression into g(n):

[tex]g(h(n/2)) = 2(h(n/2))^2 + h(n/2)[/tex]

[tex]= 2(2n + 5)^2 + (2n + 5)[/tex]

[tex]= 2(4n^2 + 20n + 25) + 2n + 5[/tex]

[tex]= 8n^2 + 42n + 35[/tex]

Therefore, [tex](g o h)(n/2) = 8n^2 + 42n + 35.[/tex]

A man wants to set up a 529 college savings account for his granddaughter. How much would he need to deposit each year into the account in order to have $70,000 saved up for when she goes to college in 15 years, assuming the account earns a 5% return.

Annual deposit: $

Answers

Using Simple interest, savings account for her needed to deposit $1,842.82 each year.

What is simple interest?

A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,

t can also be computed using the annuity factor of 5% for 17 years to divide the total sum of $50,000.

The 529 plan, according to available data, is a tax-advantaged or tax-qualified savings plan designed to encourage individuals to save for future education costs of their relations or for themselves.

Data and Calculations:

N (number of intervals) = 17 years

Interest every year is equal to 5%.

Present Value = $0 PV

FV (Future Value) = $50,000 ($31,327.88 + $18,672.12)

Results: PMT = $1,842.82

Sum of all periodic payments = $31,327.88 ($1,842.82 x 17)

Total Interest = $18,672.12

Hence, in order to save $50,000 in 17 years at a 5% return for his granddaughter, the man who wanted to open a 529 college savings account for her needed to deposit $1,842.82 each year.

Hence the interest the bank will collect will be $117.53.
