  D  Numbers that can be written as fractions

Step-by-step explanation:

A rational number is one that can be written as a ratio: a fraction with integer numerator and denominator.

__

The term "decimal" as used here is sufficiently non-specific that we cannot seriously consider it to be part of a suitable answer. A terminating or repeating decimal will be a rational number. A non-terminating, non-repeating decimal will not be a rational number.

While integers and whole numbers are included in the set of rational numbers, by themselves, they do not constitute the best description of the set of rational numbers.

The equation of the linear function is:

z = 10 + 4x + 6y

To find the equation of the linear function, we need to determine the values of c, m, and n in the function z = c + mx + ny.

Since the graph of the function intersects the xz-plane at z = 4x + 10 and the yz-plane at z = 6y + 10, we can use these equations to find the values of c, m, and n.

When the graph intersects the xz-plane (y = 0), we have:

z = c + mx + n(0) = c + mx

Comparing this with z = 4x + 10, we can equate the coefficients:

c = 10 (the constant term)

m = 4 (the coefficient of x)

When the graph intersects the yz-plane (x = 0), we have:

z = c + m(0) + ny = c + ny

Comparing this with z = 6y + 10, we can equate the coefficients:

c = 10 (the constant term)

n = 6 (the coefficient of y)

Therefore, the equation of the linear function is:

z = 10 + 4x + 6y

The sinusiodal function created from 2 given points is y = 3 sin (πx + 90) + 3

From the case, we have:

Minimum point = (-3,0)

Maximum point = (-9,6)

The sinusoidal fuction would be in the form of:

y = A sin (Bx - C) + D

where:

A = amplitudo

B = 2π / Period

C = Phase shift

D = Midline

First, we need to find the amplitudo:

A = (Y max - Y min) / 2

A = (6 - 0) / 2

A = 3

Periode = (X max - X min) x 2

Periode = (-9 - (-3) x 2

Periode = -6

B = 2π / Periode

B = 2π / 6

B = 1/3 π

D = (Y max + Y min) / 2

D = (6 + 0) / 2

D = 3

We can use one point to find the value of C:

0 = 3 sin (π/3 (-3) - C) + 3

0 = 3 sin (π - C) + 3

-3 = 3 sin (π - C)

sin (π - C) = -1

(π - C) = 270

C = -1/2 π

C = - 90

Then the sinusiodal function would be:

y = 3 sin (πx + 90) + 3

The coefficient of determination, denoted by R^2, is a measure of how well the regression model fits the data. It represents the proportion of the total variation in the dependent variable (sales dollars) that is explained by the independent variable (number of contacts).

In this case, we can use the formula:

R^2 = SS_regression / SS_total

where SS_regression is the sum of squares of the regression (13,591.17) and SS_total is the total sum of squares (14,249.12).

Thus,

R^2 = 13,591.17 / 14,249.12

R^2 = 0.953

Therefore, the coefficient of determination is 0.953 or 95.3%. This means that 95.3% of the variation in sales dollars can be explained by the number of contacts made by the salesperson, and the remaining 4.7% is due to other factors not included in the model.

The lines given by hx,y,zi = ht + 4, 4t + 5, t − 2i and hx,y,zi = h2s + 3, s + 1, 2s − 3i do not intersect.

We can determine whether two lines intersect by setting their equations equal to each other and solving for the values of x, y, and z. Setting the given equations equal to each other, we have:

ht + 4 = h2s + 3

4t + 5 = s + 1

t − 2 = 2s − 3

From the second equation, we have s = 4t - 4. Substituting this into the third equation, we get t = 3. Then, using t = 3 in the first equation, we get h = -1/3. Substituting these values into the second equation, we get s = 8. However, using these values in the first equation leads to a contradiction: -1/3 ≠ 19/3. Therefore, the lines do not intersect.

Therefore, the lines given by hx,y,zi = ht + 4, 4t + 5, t − 2i and hx,y,zi = h2s + 3, s + 1, 2s − 3i do not intersect.

The percentage mark-up of the goods is 69 percent.

The mark-up percentage is calculated by subtracting the unit cost from the selling price, dividing by the unit cost and multiplying times 100.

Therefore, the buyer for a chain of stores purchased tables in bulk, paying $200 each. The stores will sell each table for $338.

Hence, the percentage mark-up can be calculated as follows:

percentage mark-up = 338 - 200 / 200 × 100

percentage mark-up = 138 × 100 / 200

percentage mark-up = 13800 / 200

percentage mark-up = 138 / 2

Answer:

-0.301

Step-by-step explanation:

Correct Question :-

If log 2 = 0.301 , find log 0.5

Solution :-

We are here given that the value of log 5 is 0.699 . Here the base of log is 10 .

\(\rm\implies log_{10}2= 0.301 \)

And we are supposed to find out the value of log 0.5 . We can write it as ,

\(\rm\implies log_{10}(0.5) = log _{10}\bigg( \dfrac{5}{10}\bigg)\)

Simplify ,

\(\rm\implies log _{10}\bigg( \dfrac{1}{2}\bigg)\)

This can be written as ,

\(\rm\implies log_{10} ( 2^{-1})\)

Use property of log ,

\(\rm\implies -1 \times log_{10}2 \)

Put the value of log 2 ,

\(\rm\implies -1 \times 0.301 =\boxed{\blue{-0.301}} \)

Hence the value of log (0.5) is -0.301 .

The required coupon rate of Samantha's bond is 4%.

The coupon rate is the annual income an investor can expect to receive while holding a particular bond. It is fixed when the bond is issued and is calculated by dividing the sum of the annual coupon payments by the par value. At the time it is purchased, a bond's yield to maturity and its coupon rate are the same.c

We have,

principal amount = $600

Amount after five year = $720

Interest of five year = $(720 - 600) = $120

Then,

Interest of one year = $120/5 = $24

Now,

Coupon rate = ($24/600)×100 = 4%

To find two solutions of the equation y=186,000x, we can plug in any value for x and solve for y. For example, if x=1 second, then y=186,000 miles per second. This means that light travels 186,000 miles in one second, which is the speed of light in a vacuum.

Another solution can be found by setting x=10 seconds. Then, y=1,860,000 miles, which means that light can travel 1,860,000 miles in 10 seconds.
In general, the equation y=186,000x represents the distance that light travels in x seconds. This equation assumes that light travels at a constant speed of 186,000 miles per second, which is the speed of light in a vacuum. The equation can be used to calculate the distance that light travels in any given amount of time.

Overall, the two solutions found for y=186,000x represent the distance that light travels in one second and ten seconds. These values can be used to better understand the speed and distance of light in space.

The closest measurement to the volume of the container would be 738 cubic centimeters.

Assuming that the container has a cylindrical shape, the volume can be calculated using the formula for the volume of a cylinder:

V = πr^2h

where V is the volume, r is the radius, and h is the height of the cylinder.

Since the diameter of the container is given as 8 centimeters, the radius is half of that, which is 4 centimeters.

Therefore, the volume of the container is:

Step-by-step explanation:

The helium ground state wavefunction Ψ(1,2) = 2√(1s(1)1s(2)[α(1)β(2)−β(1)α(2)]) is normalized.

To show that the wavefunction Ψ(1,2) is normalized, we need to calculate the integral of Ψ(1,2) squared over all variables and demonstrate that the result is equal to 1.

The integral is given by:

\(∬[Ψ(1,2)]^2 dτ₁dτ₂\),

where dτ₁ is the volume element for particle 1, dτ₂ is the volume element for particle 2, and dτ = dv dγ is the product of the volume dv and spin dγ variables.

To simplify the integral, we can first square the wavefunction Ψ(1,2) and then integrate over the spatial and spin coordinates. Since the spin variables are orthogonal, the spin part of the integral will evaluate to 1.

The spatial part of the integral can be calculated by considering the overlap of the hydrogenic 1s orbitals for both particles.

This overlap depends on the inter-particle distance and can be solved using the radial wavefunction for the 1s state. After performing the integration, we find that the spatial part evaluates to 1/2.

Multiplying the spatial part by the spin part, we obtain a final result of 1/2 * 1 = 1, demonstrating that the wavefunction Ψ(1,2) is normalized.
