pls give me the height only!!

Answer:

2/3

Step-by-step explanation:

Caroline leaves her house and walks north 6 blocks. She turns and heads east 8 blocks until she reaches Mattie’s house.

The shortest distance between Caroline's and Mattie's house is 10 blocks.

If we assume this as a right angle triangle then height (BA) is 6 blocks long and base (BC) is 8 blocks

long.

Then, the shortest distance between Caroline's and Mattie's house will be the hypotenuse (AC) of this

triangle.

So, by applying Pythagoras theorem:

\((AC)^{2} = (BA)^{2} = (BC)^{2} = (6)^{2}+(8)^{2}\) = 36+64 = 100

Thus, AC = \(\sqrt{100}\) = 10 blocks.

Hence, the shortest distance we can take from Caroline's house to reach Mattie's house is 10 blocks.

In order to determine which model is preferred, we need to take into account the significance of the independent variables and the overall fit of the model. It is important to note that having a differing number of independent variables does not necessarily mean one model is better than the other.

Firstly, we need to analyze the significance of the independent variables in both models. A variable is considered significant if it has a p-value less than 0.05. If one model has more significant variables than the other, it may be preferred. However, if both models have similar levels of significance, we need to look at the overall fit of the model.

One way to assess the overall fit of the model is to look at the R-squared value. This value indicates the proportion of variation in the dependent variable that can be explained by the independent variables. A higher R-squared value indicates a better fit. However, this value should be interpreted in the context of the specific problem and should not be used as the sole determinant of model preference.

In addition, other factors such as the complexity of the model and the interpretability of the results should also be considered when deciding which model is preferred.

Therefore, the answer to the question of which model is preferred cannot be determined solely based on the fact that the two models have a differing number of independent variables. It requires a thorough analysis of the significance of the independent variables, the overall fit of the model, and other relevant factors.

Based on the given information, the amount of capital this year (K1) could be something less than 25 (option c).

To determine the amount of capital this year based on the given information, we can use the investment and depreciation rates.

Let's denote the amount of capital this year as K1.

According to the information provided:

People invest 55% of income, but we don't have any information about income. Therefore, we cannot determine the exact investment amount.

10% of capital depreciates. Based on this, the capital at the beginning of this year (K1) can be calculated as follows:

K1 = K - 0.1K

= 0.9K

Since we know that the capital last year was equal to 25, we substitute K = 25 into the equation above:

K1 = 0.9 * 25

= 22.5

Therefore, based on the given information, the amount of capital this year (K1) could be something less than 25 (option c).

If the standard deviation of a set of data is 6, then the value of variance is 36

The formula for determining variance is variance = √Standard deviation

Variance of a set of data is equal to square of the standard deviation.

If the standard deviation of a set of data is 6 then we get variance by putting the value of standard deviation in the formula

variance = √Standard deviation

Take square root on both sides

Standard deviation² = 6²

Standard deviation= 36

Hence,  standard deviation of a set of data is 6, then the value of variance is 36

We may build up a proportion and solve for the scale model radius of Neptune using the ratio between the radii of the two planets and the known scale model radius of the Earth. The scale model of Neptune that is produced has a radius of around 9.7 cm.

We may take advantage of the fact that the ratio between the two planets' radii and the ratio between their respective scale model radii is the same. Let's name the Neptune scale model radius "r" Then, we may set up the ratio shown below:

Neptune's radius is equal to the product of Earth's radius and its scale model.

With the provided values, we may simplify and obtain:

24620 km / 6370 km equals 2.5 cm / r

We obtain the following when solving for "r":

r = (24620 km * 2.5 cm) / (6370 km)

r ≈ 9.7 cm

Answer:  a)  y - 4 = 2/3(x) - 2

b)  y - 4 = -3/2(x) -2

Step-by-step explanation:

equation of original line:  y = 2/3x -5

point on a line parallel to original line:  (3,4)

The slope of a line parallel to a given line has the same slope, so the equation of the parallel line (in point-slope form) is:

(y - y1) = 2/3(x - x1)

point (x1, y1) is (3, 4)

plug (3,4) into the equation:

y - 4 = 2/3(x - 3)

y - 4 = 2/3(x) - 2

rewrite in slope-intercept form:  y = 2/3(x) + 2

The slope of a line perpendicular to another line is the negative reciprocal of the slope of the first line:  - 1/m

Therefore, the slope of the perpendicular line = -3/2

Equation for the perpendicular line is:

y - 4 = -3/2(x) -2

The standard deviation for the prices paid for this particular model of car is $6,250.

Based on the figure you provided, we know that the data is normally distributed and approximately 68% of car buyers pay within one standard deviation of the mean, approximately 95% pay within two standard deviations, and approximately 99.7% pay within three standard deviations.

Since we know that 95% of the prices paid fall within two standard deviations of the mean, we can say that the distance between the mean and the upper or lower limit of this range is equal to two standard deviations. This is also known as the "95% confidence interval."

Therefore, to find the standard deviation, we can calculate the distance between the mean and either the upper or lower limit of the 95% confidence interval and then divide it by two.

From the figure, we can see that the 95% confidence interval extends from approximately $23,500 to $48,500. The midpoint of this interval is approximately $36,000, which we can take as the mean.

So, the distance between the mean and either end of the 95% confidence interval is:

$48,500 - $36,000 = $12,500

Dividing this by two gives us the standard deviation:

$12,500 / 2 = $6,250

Therefore, the standard deviation for the prices paid for this particular model of car is $6,250.

Step-by-step explanation:

None of the given options matches this general solution, so the answer is E. None of the options.

To solve the given ordinary differential equation:

y'' + 2y' + 5y = e^t sin(t)

We first find the characteristic equation:

r^2 + 2r + 5 = 0

Using the quadratic formula, we find the roots to be:

r = (-2 ± sqrt(4 - 4(1)(5))) / 2

r = -1 ± 2i

The characteristic equation has complex roots, so the general solution is:

y(t) = e^(-t)(Acos(2t) + Bsin(2t))

Next, we find the particular solution by guessing a solution of the form:

y_p(t) = Ae^t sin(t) + Be^t cos(t)

Taking the first and second derivatives, we get:

y_p'(t) = Ae^t sin(t) + Ae^t cos(t) + Be^t sin(t) - Be^t cos(t)

y_p''(t) = 2Ae^t cos(t) - 2Be^t sin(t)

Substituting these expressions into the original equation and simplifying, we get:

(2A - B) e^t sin(t) + (-2B - A) e^t cos(t) = e^t sin(t)

We need the coefficients of e^t sin(t) and e^t cos(t) to be equal to 1 and 0, respectively, in order to obtain a particular solution. This gives us the system of equations:

2A - B = 1

-2B - A = 0

Solving for A and B, we get:

A = 1/5

B = -2/5

Therefore, the particular solution is:

y_p(t) = (1/5) e^t sin(t) - (2/5) e^t cos(t)

The general solution is then the sum of the homogeneous and particular solutions:

y(t) = e^(-t)(Acos(2t) + Bsin(2t)) + (1/5) e^t sin(t) - (2/5) e^t cos(t)

To solve for the constants A and B using the initial conditions, we can substitute y(0) = 0 and y'(0) = 1 into the general solution and solve the resulting system of equations. However, since the question asks us to avoid solving for the constants, we can simply write the general solution as:

y(t) = e^(-t)(Acos(2t) + Bsin(2t)) + e^t (Csin(t) + Dcos(t))

where A, B, C, and D  are constants that we do not need to solve for.

Diameter can be converted into radius form by dividing it by 2. This is because the diameter is the distance across a circle passing through the center point, whereas the radius is the distance from the center point to any point on the edge of the circle.

Therefore, to convert the diameter to radius form, we need to find the radius, which is half the diameter. In other words, the radius is equal to the diameter divided by 2. This is a simple formula that can be used to convert any given diameter into radius form.
The diameter of a circle is the distance across the circle through its center. The radius is the distance from the center to any point on the circle. Since the diameter passes through the entire circle, it covers two radius lengths.

If "d" represents the diameter, you can find the radius "r" by using the formula:

r = d/2

So, just divide the diameter by 2 to get the radius form.

The equation log₂(x - 1) = x³ - 4x has one solution at x = 2.

To determine the solutions to the equation log₂(x - 1) = x³ - 4x, we can set the two expressions equal to each other:

log₂(x - 1) = x³ - 4x

Since we know that the graphs of the two functions intersect at the points (2, 0) and (1.1187, -3.075), we can substitute these values into the equation to find the solutions.

For the point (2, 0):

log₂(2 - 1) = 2³ - 4(2)

log₂(1) = 8 - 8

0 = 0

The equation holds true for the point (2, 0), so (2, 0) is one solution.

For the point (1.1187, -3.075):

log₂(1.1187 - 1) = (1.1187)³ - 4(1.1187)

log₂(0.1187) = 1.4013 - 4.4748

-3.075 = -3.0735 (approx.)

The equation is not satisfied for the point (1.1187, -3.075), so (1.1187, -3.075) is not a solution.

Therefore, the equation log₂(x - 1) = x³ - 4x has one solution at x = 2.
