Answer:

No only variable on both sides have no solution

Step-by-step explanation:

Then you can get,

for example x=x

or,

y=y

Answer:

Step-by-step explanation:

A. Every equation with variables on both sides has no solution.​ However, it is also possible for an equation with the variable on only one side to also have no solution.

B. If the variable only appears on one side of an​ equation, then the equation can always be solved for the variable. This means that if an equation has no​ solution, then the variable must appear on both sides.

C. Any equation can have one​ solution, infinitely many​ solutions, or no solutions. This does not depend on whether the variable appears on only one side or on both sides.

D. If the variable only appears on one side of an​ equation, then the equation can always be solved for the variable. By​ contrast, an equation with variables on both sides always has no solution or infinitely many solutions.

The general solution to the system of equations is:

x(t) = c1*[1, 1]*exp(0*t) + c2*[1, -1]*exp(2*t)

where c1 and c2 are constants.

To find a linearly independent pair of solutions for the given system of equations, we first need to find the eigenvalues and eigenvectors of the coefficient matrix.

The coefficient matrix is

[ 1 -1 ]

[ 1 -1 ]

The characteristic equation is:

det(A - λI) = 0

where A is the coefficient matrix, λ is the eigenvalue and I is the identity matrix.

Substituting the values we get,

det( [1-λ -1  ] ) = (1-λ)(-1) - (-1)(-1) = λ^2 - 2λ = 0

    [-1  1-λ]

Solving for λ, we get λ=0, λ=2.

Now we need to find the eigenvectors for each eigenvalue λ.

For λ=0, we have:

(A - 0I)x = 0

[1  -1] [x1]   [0]

[1  -1] [x2] = [0]

This gives us the equation x1 = x2. Thus, any vector of the form [t, t] where t is any non-zero constant will be an eigenvector corresponding to λ=0.

For λ=2, we have:

(A - 2I)x = 0

[-1  -1] [x1]   [0]

[ 1  -1] [x2] = [0]

This gives us the equation x1 + x2 = 0. Thus, any vector of the form [t, -t] where t is any non-zero constant will be an eigenvector corresponding to λ=2.

Therefore, a linearly independent pair of solutions is:

x1 = [1, 1], corresponding to λ=0

x2 = [1, -1], corresponding to λ=2

So the general solution to the system of equations is:

x(t) = c1*[1, 1]*exp(0*t) + c2*[1, -1]*exp(2*t)

where c1 and c2 are constants.

Answer:

Hi! A piecewise function is a function defined by multiple sub-functions, or pieces of different functions over different intervals. Piecewise definition is a way of expressing the function and is not actually integral to the function itself.

f(x) = |x - 2| is an absolute value function. As a piecewise function, it's written like this:

f(x) = {x - 2, x ≥ 2

        {-x + 2, x < 2

To find the surface area of the figure, we need to consider the individual surfaces and add them together.

First, let's identify the surfaces of the figure:

The lateral surface area of the larger prism (excluding the base)

The two bases of the larger prism

The lateral surface area of the smaller prism (excluding the base)

The two bases of the smaller prism

The lateral surface area of a prism is given by the formula: perimeter of the base multiplied by the height.

The bases of the prisms are rectangles, so their areas can be calculated by multiplying the length by the width.

To find the missing prism's surface area, we need to consider that it is a smaller prism nested inside the larger prism. The lateral surface area and bases of the missing prism should also be included.

Once we have calculated the individual surface areas, we add them together to find the total surface area of the figure.

Without specific measurements or dimensions of the figure, it is not possible to provide a numerical answer. Please provide the necessary measurements or dimensions to calculate the surface area.

the first meal was $7.89, which is roughly $8the second meal was $9.05, which is roughly $9

Answer:

5.2

Step-by-step explanation:

adding all the numbers together and dividing it by 10.

Answer:

mean = 5.2

Step-by-step explanation:

The mean (or average) of a group of numbers is defined as the value calculated by adding all the given numbers together and then dividing the result by the number of numbers given.

Therefore,

\(\boxed{\mathrm{mean = \frac{sum \ of \ the \ numbers}{number \ of \ numbers}}}\).

In the question, the numbers given are: 3, 7, 2, 4, 7, 5, 7, 1, 8, and 8.

Therefore,

sum = 3 + 7 + 2 + 4 + 7 + 5 + 7 + 1 + 8 + 8

       = 52

There are 10 numbers given in the question. Therefore, using the formula given above, we can calculate the mean:

\(\mathrm{mean = \frac{52}{10}}\)

            \(= \bf 5.2\)

Hence, the mean of the given numbers is 5.2.

Since the volume of the sphere V = 36π cm³is less than that of the cone, V' = 45π cm³ the ice cream will not overflow.

The volume of a sphere is given by V = 4πr³/3 where r = radius of sphere

To determine if the ice cream above is going to melt and when it does, will it fit in the cone or will it overflow? We know that the ice cream is a sphere, the ice cream will not overflow if the volume of the ice cream equals the volume of the cone. If its volume is greater than the volume of the cone, it will overflow.

We know that the ice cream is a sphere, we determine its volume as V = 4πr³/3 where r = radius of sphere = 3 cm

We substitute the variable into the equation,

V = 4πr³/3

V = 4π(3 cm)³/3

V = 4π × 27 cm³/3  

= 4π × 9 cm³

= 36π cm³

Next, we determine the volume of the cone to be V' = 1/3πr²h where

We now substitute the variables into the equation, thus

V' = 1/3πr²h

V' = 1/3π(3 cm)² × 15 cm

= 1/3π × 9 cm² × 15 cm

= 3π cm² × 15 cm

= 45π cm³

We see that V = 36π cm³ < V' = 45π cm³

Since the volume of the sphere is less than that of the cone, the ice cream will overflow.

\(x_{1} =9\)

\(y_{1} =-8\)

At point B (-6,7),

\(x_{2} =-6\)

\(y_{2} =7\)

Use the formula has given in the problem which is,

\(x=\dfrac{m}{m+n}(x_{2} -x_{1} )+x_{1}\)

Put the values,

\(x=\dfrac{2}{3}(-6 -9 )+9\)

\(x=\dfrac{2}{3}(-15 )+9\)

\(x=2(-5 )+9\)

\(x=-10+9\)

\(x=-1\)

For y use the formula given in the problem which is

\(y=\dfrac{m}{m+n}(y_{2} -y_{1} )+y_{1}\)

\(y=\dfrac{2}{3}(7 -(-8) )+(-8)\)

\(y=\dfrac{2}{3}(7+8) )-8\)

The coordinates of transforming image of the vertices of the triangle ABC are A' (1, -1) ,B' (3, 1) , and C' (1, 4).

In triangle ABC,

Coordinates of the vertices of triangle ABC are,

A(-1,1), B(1,3) and C(4,1)

The transformation T y=x reflects the points across the line y=x.

The image of each point, we simply swap the x and y coordinates of each point.

So, applying the transformation T y=x to the vertices of triangle ABC, we get,

A' = (-1, 1) → (1, -1)

B' = (1, 3) → (3, 1)

C' = (4, 1) → (1, 4)

This implies,

The image of triangle ABC under the transformation T y=x is triangle A'B'C', where,

A' is located at (1, -1)

B' is located at (3, 1)

C' is located at (1, 4)

Comparing the areas of triangles ABC and DEF, we can see that both triangles have the same area of 6 square units.

To compare the areas of triangles ABC and DEF, we can use the formula for calculating the area of a triangle, which is:

Area = (1/2) * base * height

Triangle ABC:

The base of triangle ABC can be calculated as the distance between points (4, 2) and (7, 2), which is 7 - 4 = 3 units.

The height of triangle ABC can be calculated as the distance between points (4, 2) and (4, 6), which is 6 - 2 = 4 units.

Therefore, the area of triangle ABC is (1/2) * 3 * 4 = 6 square units.

Triangle DEF:

The base of triangle DEF can be calculated as the distance between points (-2, -1) and (4, -1), which is 4 - (-2) = 6 units.

The height of triangle DEF can be calculated as the distance between points (4, -1) and (4, -3), which is -3 - (-1) = -2 units (taking the absolute value, the height is 2 units).

Therefore, the area of triangle DEF is (1/2) * 6 * 2 = 6 square units.

The compound interest on N2,000 for 2 years at the rate of 10% per annum is N441.00.

Compound interest is the interest earned not only on the principal amount but also on the accumulated interest. To calculate the compound interest, we use the formula:

where A is the final amount, P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years.

In this case, P = N2,000, r = 0.1 (10%), n = 1 (compounded annually), and t = 2 years.

So, A = 2000\((1 + 0.1/1)^{(1*2)\) = N2,441.00

Therefore, the compound interest is N2,441.00 - N2,000.00 = N441.00.

It would take Farmer John 10 hours on his own to till his field.

Step-by-step explanation:

Let;

J = Time spent by John alone

B = Time spent by Bob alone = 1.5 * J = 1.5J

Time spent by both = 6

Using reciprocal, time spent by John alone can be calculated as follows:

(1 / J) + (1 /1.5J) = 1 / 6

Multiply through by 6J and solve for J, we have:

(6J / J) + (6J / 1.5J) = 6J / 6

6 + (6 / 1.5) = J

J = 6 + 4 = 10
