Answer:

The radius is a line segment that starts at the center of the circle and ends at a point on the circle.

Step-by-step explanation:

The radius is half of the diameter. The diameter is one line going across the whole, through the midpoint. The radius starts at the midpoint and that's why it's only half of the diameter.

Answer: The radius is a line segment that starts at the center of the circle and ends at a point on the circle.

Step-by-step explanation:

Let's check all the options.

The radius is a line segment joining two distinct points on the circle. → Wrong.

Reason :- Radius joins center and any point on circle not any two points.

The radius is the boundary of a circle. → Wrong.

Reason :- Circumference is the boundary of circle ,

Formula for circumference C= 2π r , where r is radius .

The radius is a line segment that starts at one point on the circle, passes through the center of the circle, and ends at another point on the circle.→ Wrong.

Reason :- Its diameter that starts at one point on the circle, passes through the center of the circle, and ends at another point on the circle and it is twice of radius.

So , the best answer that defines the radius of a circle is The radius is a line segment that starts at the center of the circle and ends at a point on the circle.

Answer:

Step-by-step explanation:

Given that the solution of a certain differential equation is of the form

[tex]y(t) = ae^{7t} +be^{11t}[/tex]

Use the initial conditions

i) y(0) =1

[tex]1=a(1)+b(1)\\a+b=1[/tex] ... I

ii) y'(0) = 4

Find derivative of y first and then substitute

[tex]y'(t) = 7ae^{7t} +11be^{11t}\\y'(0) =7a+11b \\7a+11b =4 ...II[/tex]

Now using I and II we solve for a and b

Substitute b = 1-a in II

[tex]7a+11(1-a) = 4\\-4a+11 =4\\-4a =-7\\a = 1.75 \\b = -0.75[/tex]

Hence solution is

[tex]y(t) = 1.75e^{7t} -0.75e^{11t}[/tex]

Answer:

y(t) = a exp(3t) + b exp(4t) conditions, y(0) = 3 y'(0) = 3 y(0) = a exp(3 x 0) + b exp(4 x 0) = a exp(0) + b exp(0) = (a x 1) + (b x 1) = a + b y'(0) = 0 so the linear equation is, a + b = 3

Answer:

[tex]y(t)\ =\ C_1.e^{-2t}+C_2e^t-\ t.\dfrac{e^{-2t}}{3}-\dfrac{1}{3}[/tex]

Step-by-step explanation:

Given differential equation is,

     y"+y'-2y=1

[tex]=>\ (D^2+D-2D)y\ =\ 1[/tex]

To find the complementary function we will write,

    [tex]D^2+D-2=0[/tex]

[tex]=>\ D\ =\ \dfrac{-1+\sqrt{1^2+4\times 2\times 1}}{2\times 1}\ or\ \dfrac{-1-\sqrt{1^2+4\times 2\times 1}}{2\times 1}[/tex]

[tex]=>\ D\ =\ -2\ or\ 1[/tex]

Hence, the complementary function can be given by

[tex]y(t)\ =\ C_1e^{-2t}\ +\ C_2e^t[/tex]

Let's say,

[tex]y_1(t)\ =\ e^{-2t}\ \ =>y'_1(t)\ =\ -2e^{-2t}[/tex]

[tex]y_2(t)\ =\ e^{t}\ \ =>y'_2(t)\ =\ e^{t}[/tex]

[tex]g(t)\ =\ 1[/tex]

Wronskian can be given by,

[tex]W\ =\ y_1(t).y'_2(t)\ -\ y_2(t).y'_1(t)[/tex]

     [tex]=\ e^{-2t}.e^{t}\ -\ e^{t}.(-2e^{-2t})[/tex]

     [tex]=\ e^{-t}\ +\ 2e^{-t}[/tex]

     [tex]=\ 3.e^{-t}[/tex]

Now, the particular integral can be given by

[tex]y_p(t)=\ -y_1(t)\int\dfrac{y_2(t).g(t)}{W}dt\ +\  y_2(t)\int\dfrac{y_1(t).g(t)}{W}dt[/tex]

        [tex]=\ -e^{-2t}\int\dfrac{e^t.1}{3.e^{-t}}+e^t\int\dfrac{e^{-2t}.1}{3.e^{-t}}dt[/tex]

       [tex]=\ -e^{-2t}\int\dfrac{1}{3}dt+\dfrac{e^t}{3}\int e^{-t}dt[/tex]

       [tex]=\ \dfrac{-e^{-2t}}{3}.t\ -\ \dfrac{e^t}{3}.e^{-t}[/tex]

        [tex]=\ -t.\dfrac{e^{-2t}}{3}-\dfrac{1}{3}[/tex]

Hence, the complete solution can be given by

[tex]y(t)\ =\ C_1.e^{-2t}+C_2e^t-\ t.\dfrac{e^{-2t}}{3}-\dfrac{1}{3}[/tex]

Answer:

The solution of the system of linear equations is [tex]x=3, y=4, z=1[/tex]

Step-by-step explanation:

We have the system of linear equations:

[tex]2x+3y-6z=12\\x-2y+3z=-2\\3x+y=13[/tex]

Gauss-Jordan elimination method is the process of performing row operations to transform any matrix into reduced row-echelon form.

The first step is to transform the system of linear equations into the matrix form. A system of linear equations can be represented in matrix form (Ax=b) using a coefficient matrix (A), a variable matrix (x), and a constant matrix(b).

From the system of linear equations that we have, the coefficient matrix is

[tex]\left[\begin{array}{ccc}2&3&-6\\1&-2&3\\3&1&0\end{array}\right][/tex]

the variable matrix is

[tex]\left[\begin{array}{c}x&y&z\end{array}\right][/tex]

and the constant matrix is

[tex]\left[\begin{array}{c}12&-2&13\end{array}\right][/tex]

We also need the augmented matrix, this matrix is the result of joining the columns of the coefficient matrix and the constant matrix divided by a vertical bar, so

[tex]\left[\begin{array}{ccc|c}2&3&-6&12\\1&-2&3&-2\\3&1&0&13\end{array}\right][/tex]

To transform the augmented matrix to reduced row-echelon form we need to follow these row operations:

[tex]\left[\begin{array}{ccc|c}1&3/2&-3&6\\1&-2&3&-2\\3&1&0&13\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc|c}1&3/2&-3&6\\0&-7/2&6&-8\\3&1&0&13\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc|c}1&3/2&-3&6\\0&-7/2&6&-8\\0&-7/2&9&-5\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc|c}1&3/2&-3&6\\0&1&-12/7&16/7\\0&-7/2&9&-5\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc|c}1&3/2&-3&6\\0&1&-12/7&16/7\\0&0&3&3\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc|c}1&3/2&-3&6\\0&1&-12/7&16/7\\0&0&1&1\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc|c}1&3/2&-3&6\\0&1&0&4\\0&0&1&1\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc|c}1&3/2&0&9\\0&1&0&4\\0&0&1&1\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc|c}1&0&0&3\\0&1&0&4\\0&0&1&1\end{array}\right][/tex]

From the reduced row echelon form we have that

[tex]x=3\\y=4\\z=1[/tex]

Since every column in the coefficient part of the matrix has a leading entry that means our system has a unique solution.

Answer:

The equation for this line, in slope-intercept form, is given by:

[tex]y = - 9[/tex]

Step-by-step explanation:

The equation of a line in the slope-intercept form has the following format:

[tex]y = ax + b[/tex]

In which a is the slope of the line and b is the y intercept.

Solution:

The line has the same y-intercept as [tex]y + 1 = 4 (x - 2)[/tex].

So, we have to find the y-intercept of this equation

[tex]y + 1 = 4 (x - 2)[/tex]

[tex]y = 4x - 8 - 1[/tex]

[tex]y = 4x - 9[/tex]

This equation, has the y-intercept = -9. Since this line has the same intercept, we have that [tex]b=-9[/tex].

Fow now, the equation of this line is

[tex]y = ax - 9[/tex]

The line contains the point [tex](9,-9)[/tex]

This means that when [tex]x = 9, y = -9[/tex]. We replace this in the equation and find a

[tex]y = ax - 9[/tex]

[tex]-9 = 9a - 9[/tex]

[tex]9a = 0[/tex]

[tex]a = \frac{0}{9}[/tex]

[tex]a = 0[/tex]

The equation for this line, in slope-intercept form, is given by:

[tex]y = - 9[/tex]

Answer:

Qualitative and Neither

Step-by-step explanation:

Quantitative data is such a data which can be measured or calculated i.e. which is defined only in terms of numbers. In simple words we can say that numeric data is the Quantitative data.

On the other hand, qualitative data describes the characteristics, attribute or quality of the objects. This type of data is not measured or calculated.

The data which we are dealing with is "Kind of pizza". The kind/flavor of pizza is an attribute or characteristic of pizza. So from here it is clear that the data is Qualitative. Though numbers are assigned  to different flavors, these numbers are just for identification of the flavor on the order form.

The terms discrete and continuous can only be used when the data is Quantitative. Qualitative data cannot be referred to as discrete or continuous data, even if some numbers are assigned to data.

Therefore, the answers are: Qualitative and Neither

Answer:

2500

Step-by-step explanation:

We have to find the largest product of two numbers whose sum is 100.

Let the two numbers be x and y.

Thus, we can write x+y=100

We can calculate the value of y as:

y = 100 - x

The product of these number can be written as: (x)(y) = (x)(100-x) = 100x - x²

Let f(x) = 100x - x²

Now, the first derivative of this function with respect to x is

[tex]\frac{df(x)}{dx}[/tex] = 100-2x

Equating [tex]\frac{df(x)}{dx}[/tex] = 0, we get,

100-2x = 0

⇒ x = 50

Now, we find the second derivative of the the function f(x) with respect to x

[tex]\frac{d^2f(x)}{dx^2}[/tex] = -2

Since, [tex]\frac{d^2f(x)}{dx^2}[/tex] < 0, then by double derivative test the function have a local maxima at x = 50

This, x = 50 and y = 100-50 =50

Largest product = (50)(50) = 2500

Answer: 0.4729%

Step-by-step explanation:

The formula to find the percent of a part in total amount :-

[tex]\%=\dfrac{\text{Part}}{\text{Total}}\times100[/tex]

Given : Total amount = 1,1050.00

Part of total amount = 52.25

Now, substitute all the values in the formula , we get

[tex]\%=\dfrac{52.25}{11050}\times100\\\\\Rightarrow\ \%=\dfrac{5225}{1105000}\times100=\dfrac{5225}{11050}=0.472850678733\approx0.4729\%[/tex]

Hence, 52.25 is 0.4729% of 1,1050.00.

Answer:

a) False b) False c) True d) True e) True

Step-by-step explanation:

a) If A is a subset of B, and x∈B, then x∈A. False

Suppose A is Z (Set of Integers), and B is R (Set of Real Numbers). Then A is a subset of B. x ∈ B, let's say x equals π. If x ∈ B (B = Real Numbers) and x=π then x ∉ A (Z).

We could call A, any other subset of Real numbers (Q, I,..) and we both would come up to the same conclusion when it comes to Real numbers the Set.

So this conclusion is False. Not always an element of a subset is an element of a set.

b) False

For this one, I've drawn some lines, and it is useful to work with them.

Given the set {(x,y) ∈ R²| 0<x<0} then all negative and positive numbers but zero belong to this set.

c) If A and B are square matrices, then AB is also square. True

Taking into account the rules for multiplying matrices. The number of columns of A must be the same number of lines of B to there can be a matrix product.

Whenever we multiply square matrices, we'll always get square matrices. Then this conclusion is true.

d) A and B are subsets of a set S, then A∩B and A∪B are also subsets of S. True

Suppose A= Z (Integer Numbers) and B=Q (Rational Numbers) and S= R (Real Numbers)

A∩B = Z∩Q=∅ and A∪B =Z∪Q = subset

Since the ∅ empty set ⊂ in every set and ZUQ is another Subset of R this is a True conclusion.

e) True. For a matrix A, we define A²= AA

For any Power of Matrices, all we have to do is multiply any given matrix by itself for a given number of times.

Answer:

Step-by-step explanation:

As per the given question,

In a manufacturing operation, a part is produced by machining, polishing, and painting.

Number of machine tools = 3

Number of polishing tools = 4

Number of painting tools = 3

Now,

For finding the different routing consisting of machining, followed by polishing, and followed by painting, we have to simply multiply the number of machine tools, polishing tools and painting tools.

Therefore,

The different routing (consisting of machining, followed by polishing, and followed by painting) for a part are possible = 3 × 4 × 3 = 36.

Hence, the required answer is 36.

Number of ways a process can be done is the count of total distinguished ways that process can be done. The count of different routings possible for a part is 36

Suppose that a process A can be done in 'a' different ways.
And there is a process following A, call it B, can be done in 'b' different ways. Then, the process A then B can be done in a×b different ways.

This is called rule of product in combinatorics.

Since there are 3 processes to be done subsequently(machining, polishing, then painting), and each of them can be done in 3, 4, and 3 ways respectively, thus,

Total number of routings possible for a part is [tex]3 \times 4 \times 3 = 36[/tex] ways.

Thus, The count of different routings possible for a part is 36

Step-by-step explanation:

The areas of the room, not including the ceiling, are discriminated as follows:

Longer walls: [tex](12.5\times8)\times2=200ft^2[/tex] (6 inches equals one foot)

Shorter walls: [tex](10.5\times8)\times2 = 168ft ^ 2[/tex] (6 inches equals one foot)

Window area: [tex](4\times3)\times2 = 24ft ^ 2[/tex]

Door area: [tex](7\times3) = 21ft ^ 2[/tex]

Area that will be effectively covered:

Total area to wallpaper: [tex]200 + 168 -24 -21 = 323ft ^ 2[/tex]

Amount of paper needed: [tex]323\times1.1 = 355.3ft ^ 2[/tex]

[tex]30in = 24in + 6in = 2ft + 0.5ft = 2.5ft.[/tex] That is, the area of ​​a roll of paper is [tex]2.5\times30 = 75ft ^ 2[/tex]

Number of rolls needed:

[tex]\frac{355.3}{75} = 4.73[/tex] rolls

Answer:

Correct answer is B. 5Rolls

Step-by-step explanation:

12 inches is 1 feet

6 inches is 6/12 feet= 0,5 feet.

12 inches is 1 foot

30 inches is 30/12 feet=2,5feet.

2. Second,you have to calculate the total surface where you will wallpaper.

So you have to calculate the dimension of 2 different rectangles and substract the surfaces that you don't have to wallppaper (door and windows).

[tex]Area rectangle 1 =10.5feet*8feet=84ft^{2} \\Area rectangle2=12.5feet*8feet=100ft^{2}\\Total Area of walls=(Area rectangle 1 *2) + (Area rectangle2*2)\\Total Area of walls=(84ft^{2} *2)+(100ft^{2})\\\\Total Area of walls=368ft^{2}[/tex]

3. Now we have to calculate the area to substract from the total area, since you will not wallpaper the door and windows:

[tex]Windows=4feet*3feet*2=24ft^{2}  \\Door=7feet*3feet=21ft^{2}[/tex]

4. Total area to wallpaper is Total surface of the room minus door and windows surface:

[tex]wallpaperArea=368ft^{2} -45ft^{2}\\wallpaperArea=323ft^{2}[/tex]

5. Now you have to add 10% waste to the calculated surface:

[tex]323ft^{2} +(323*0.10)=355.3ft^{2}[/tex]

6. So, you have the real area that will wallpaper considering 10% waste, it is 326.23 square feet. To calculate how many rolls you will need, you have to calculate the surface that each roll covers and then divide total surface by roll surface.

[tex]Roll surface=2,5feet*30feet=75feet^{2}[/tex]

[tex]Rolls needed=355.3ft^{2}/75ft^{2}=4.73[/tex]

7. As the number of rolls is not integer you have to round, then the answer is you will need 5 rolls of wallpaper.

During the flood season, the water rises 26.4 feet up the side of the lake.

The angle of elevation is given as 15 degrees 30 minutes,

Now, it can be converted to decimal degrees as 15.5 degrees.

Let's denote the distance up the side of the lake as x feet.

Now set up a trigonometric equation using the tangent function:

tan(15.5°) = (7.3 feet) / x

We can solve for x by rearranging the equation:

x = (7.3 feet) / tan(15.5°)

Evaluating this expression gives us:

x = (7.3 feet) / 0.277

x = 26.4 feet

Therefore, the water rises 26.4 feet up the side of the lake.

The probability that all six cells are able to replicate is approximately 0.0051, while the probability that at least one cell is not capable of replication is approximately 0.9949.

To solve this problem, we need to use the concept of probability and combinations.

There are 37 - 12 = 25 cells capable of replication. Out of these, we need to select 6 cells. The probability of selecting a cell capable of replication is 25/37 for the first selection, multiplied by 24/36 for the second selection, and so on, until 20/32 for the sixth selection. So, the probability is:

P(all 6 cells able to replicate) = (25/37) * (24/36) * (23/35) * (22/34) * (21/33) * (20/32) ≈ 0.0051

The probability that at least one cell is not capable of replication is equal to 1 minus the probability that all six cells are able to replicate. So, the probability is:

P(at least one cell not able to replicate) = 1 - P(all 6 cells able to replicate) ≈ 0.9949

Step-by-step explanation:

Inverse of a function:

To find the inverse of a function [tex]y = f(x)[/tex], basically, we have to reverse r. We exchange y and x in their positions, and then we have to isolate y.

In your exercise:

[tex]y = \sqrt[3]{x} - 8[/tex]

Exchanging x and y, we have:

[tex]x = \sqrt[3]{y} - 8[/tex]

[tex]x + 8 = \sqrt[3]{y}[/tex]

Now we have to write y in function of x

[tex](x+8)^{3} = (\sqrt[3]{y})^{3}[/tex]

[tex]y = (x+8)^{3}[/tex]

So, the inverse function of [tex]\sqrt{3]{x} - 8[/tex] is [tex](x+8)^{3}[/tex]

where, m is slope and b is y-intercept.

The given equation is

[tex]4x+7y+4=7[/tex]

We need to find the slope intercept form of given line.

Subtract 4 from both sides.

[tex]4x+7y=7-4[/tex]

[tex]4x+7y=3[/tex]

Subtract 4x from both sides.

[tex]7y=3-4x[/tex]

Divide both sides by 7.

The problem is a step-by-step calculation with several possible combinations of type A and type B vehicles when a total of 101 counts are registered. A systematic approach is required to find all possible whole number solutions.

This problem is an example of a diophantine problem or a linear equation in two variables. If we denote the number of type A vehicles by 'a', and the number of type B vehicles by 'b', the problem can be represented by the equation 2a + 9b = 101.

As you are looking for all possible solutions, you have to do a systematic search. You will find that:

Answer:

The value of x is [tex]\frac{(3c+b)}{3-c}[/tex].

Step-by-step explanation:

The given equation is

[tex]cx+b=3(x-c)[/tex]

Using distributive property we get

[tex]cx+b=3(x)+3(-c)[/tex]

[tex]cx+b=3x-3c[/tex]

To solve the above equation isolate variable terms.

Subtract 3x and b from both sides.

[tex]cx-3x=-3c-b[/tex]

Taking out common factors.

[tex]x(c-3)=-(3c+b)[/tex]

Divide both sides by (c-3).

[tex]x=-\frac{(3c+b)}{c-3}[/tex]

[tex]x=\frac{(3c+b)}{3-c}[/tex]

Therefore the value of x is [tex]\frac{(3c+b)}{3-c}[/tex].

Answer:

x=2

Step-by-step explanation:

−3(4−x)+3x=3(10−5x)

(−3)(4)+(−3)(−x)+3x=(3)(10)+(3)(−5x)

−12+3x+3x=30+−15x

(3x+3x)+(−12)=−15x+30

6x+−12=−15x+30

6x−12=−15x+30

6x−12+15x=−15x+30+15x

21x−12=30

Step 3: Add 12 to both sides.

21x−12+12=30+12

21x=42
