To find the height of lighthouse.

Now, According to the question:

In Triangle ABD

tan 20° = \(\frac{h}{20 + x}\)

0.36  = \(\frac{h}{20 + x}\)

=> (20 + x)0.36 = h

=> 0.72 + 0.36x = h

=> x = \(\frac{h - 72}{0.36}\) .....(1)

In Triangle ABC

tan 34° = h/x

=> 0.67 = \(\frac{h}{\frac{h-72}{0.36} }\)

The maximum rate of change of the function f at (8,0) is 8 and the direction is ĵ.

What is function?

In mathematics, a function can be defined as a relation between a set of inputs having one output each. In simple manner, a function is a relationship between inputs where each input is related to exactly one output. In every function there has a domain and codomain or range.

Given function is f(x, y) = sin(xy)

The maximum rate of change f(x, y) occurs in the direction of gradient of the function f which can be estimated as follows:

∇f(x, y)=[ ∂/∂x f(x, y)î + ∂/∂y f(x, y)ĵ]

∇f(x, y)=[ ∂/∂x (sinxy)î + ∂/∂y (sinxy) ĵ] -------(1)

The partial derivative

∂/∂x (sinxy)= (cos xy) ∂/∂x(xy)

                 = y cos (xy)

and the partial derivative

∂/∂x (sinxy)= (cos xy) ∂/∂y(xy)

                 = x cos (xy)

putting these values in equation (1) we get,

∇f(x, y)=[ y cos(xy)î + x cos(xy) ĵ]

∇f(8, 0)=[ 0 + 8 ĵ] [ since cos 0= 1]

Now,

| ∇f(8, 0) | = | 0 + 8 ĵ |

               = \(\sqrt{(0^{2} + 8^{2}) }\)

                = 8

Hence, the maximum rate of change of the function f at (8,0) is 8 and the direction is ĵ.

 By multiplying matrices B and A, we obtain the product BA. Using BA, we can solve the system of equations y + 2z = 7, x - y = 3, and 2x + 3y + 4z = 17.the values of x, y, and z are -1, 2, and 1 respectively

To find the product BA, we multiply matrix B with matrix A. The resulting matrix will have the same number of rows as B and the same number of columns as A. The product BA will be used to solve the given system of equations.
The product BA can be computed by multiplying each row of matrix B by each column of matrix A and summing the results. The resulting matrix will be:
Now, we can use the product BA to solve the system of equations:
-10x - 10y + 6z = 7,
3x - 8y + 2z = 3,
-6x - 16y + 15z = 17.

1 -1 2
2 3 1
0 4 2
We can rewrite this system of equations as:
-10x - 10y + 6z = 7,
3x - 8y + 2z = 3,
-6x - 16y + 15z = 17.
By comparing the coefficients of x, y, and z in the system of equations with the entries in the matrix BA, we can determine the values of x, y, and z.
Solving the system of equations using matrix BA, we get:
x = -1,
y = 2,
z = 1.
Therefore, the values of x, y, and z are -1, 2, and 1 respectively.

Step-by-step explanation:

An ordered pair is a solution of an equation in two variables if replacing the variables by the coordinates of the ordered pair results in a true statement.

In mathematics, an equation in two variables represents a relationship between two quantities. An ordered pair consists of two values, typically denoted as (x, y), that represent the coordinates of a point in a two-dimensional plane.

When these values are substituted into the equation, if the equation holds true, then the ordered pair is considered a solution or a solution set to the equation. This means that the relationship described by the equation is satisfied by the values of the ordered pair. In other words, the equation is true when evaluated with the values of the ordered pair.

The volume of the cone is

\(\pi r^2 \frac{h}{3}\\\\\pi \times 3^2 \times \frac{8}{3} \\\\\frac{72}{3} \pi \\\\24 \pi\)

Now since it is two-third so the remaining is one -third

\(= 8 \pi\)

hence, the volume of water remaining is \(8 \pi\)

Logistic regression models the probability of a binary outcome, while CART models segment data into categories. For example, CART is preferable when data has complex interactions, as it can partition data into multiple categories.

Logistic regression and classification and regression trees (CART) are two different machine learning models used for binary classification problems. Logistic regression models the probability of one class or the other based on a linear combination of input variables. This makes it useful for predicting a binary outcome, such as whether a customer will purchase a product or not. On the other hand, CART is a decision tree model that divides data into categories. It uses a tree-like structure to split the data into segments based on the input features. This makes it useful for dealing with data with complex interactions, as it can partition data into multiple categories. For example, a CART model would be preferable to a logistic regression model if there are multiple underlying factors that affect the binary outcome. In this case, a CART model could more accurately identify the categories that are associated with a particular outcome. Overall, CART models are superior for dealing with data with complex interactions, whereas logistic regression is better for simpler data.

Step-by-step explanation:

The equation is true for any value of "c". We can't solve for "c" as it will cancel out during the simplification process.

To find the volume of "c" in the equation -3/2(x+4)=9-4x, we first need to isolate the variable "c" on one side of the equation.

Starting with the given equation:

-3/2(x+4)=9-4x

First, distribute the -3/2 to the term in the parentheses:

-3/2 × x - 3/2 × 4 = 9 - 4x

Simplify by multiplying:

-3/2x - 6 = 9 - 4x

Next, add 4x to both sides to get all the x terms on one side of the equation:

-3/2x + 4x - 6 = 9

Simplify by combining like terms:

5/2x - 6 = 9

Add 6 to both sides:

5/2x = 15

Finally, divide both sides by 5/2 to isolate the variable "x":

x = 6

Now we have found the value of "x". To find the value of "c", we can substitute this value of "x" back into the original equation and solve for "c":

-3/2(x+4)=9-4x

-3/2(6+4)=9-4(6)

-3/2(10)=9-24

The given statement of researchers pre-establish the rate of false rejection of the null hypothesis prior to conducting any testing for significance  is False.

The rate of false rejection of the null hypothesis prior to conducting any testing for significance is called the level of significance or alpha level.

Researchers typically establish the alpha level before conducting a significance test.

And it represents the probability of rejecting the null hypothesis when it is actually true.

The most commonly used alpha level is 0.05, which means that there is a 5% chance of rejecting the null hypothesis when it is true.

However, the alpha level is not pre-established by researchers for all tests.

In some cases, researchers may use a different alpha level based on the nature of the study, the research question, or other factors.

Additionally, the alpha level can be adjusted during the analysis to control for the overall rate of false positives in a study.

The dimension of the basis is {[1 0 0 2], [-1 1 0 0]}.

To find a basis for the subspace S = span {[1 -1 0 2], [3 -5 4 8], [0 1 -2 -1]}, we can use the same method as in the example. First, we put the vectors in a matrix and row-reduce it:

[1 -1 0 2]
[3 -5 4 8]
[0 1 -2 -1]

R2 - 3R1 -> R2
R3 -> R3 + 2R1

[1 -1 0 2]
[0 -2 4 2]
[0 1 -2 -1]

-1/2R2 -> R2

[1 -1 0 2]
[0 1 -2 -1]
[0 1 -2 -1]

R3 - R2 -> R3

[1 -1 0 2]
[0 1 -2 -1]
[0 0 0 0]

We can see that the last row is all zeros, so we have only two pivots and one free variable. This means that the dimension of the subspace S is 2. To find a basis, we can write the pivots as linear combinations of the original vectors:

[1 -1 0 2] = [1 0 0 2] + [-1 1 0 0]
[0 1 -2 -1] = [0 1 -2 -1]

Therefore, a basis for S is {[1 0 0 2], [-1 1 0 0]}.

Dante and Mia lost a total of 100 + 50 = 150 pennies.

Let's denote the number of pennies Dante initially had as "D" and the number of pennies Mia initially had as "M." According to the given information, we know that D + M = 350.

After Dante lost half of his pennies, he would have (1/2)D pennies remaining, and after Mia lost one-third of her pennies, she would have (2/3)M pennies remaining. It is stated that they both had an equal number of pennies after these losses.

Therefore, we can set up the following equation:

(1/2)D = (2/3)M

To simplify this equation, we can multiply both sides by 6 to eliminate the fractions:

3D = 4M

Now we have a system of equations:

D + M = 350
3D = 4M

We can solve this system to find the values of D and M. Multiplying the first equation by 4, we get:

4D + 4M = 1400

Substituting 3D for 4M from the second equation, we have:

4D + 3D = 1400
7D = 1400
D = 200

Substituting D = 200 back into the first equation, we find:

200 + M = 350
M = 150

So, Dante initially had 200 pennies, and Mia initially had 150 pennies.

To find out how many pennies they lost, we need to calculate the difference between their initial amounts and their final amounts:

Dante lost: 200 - (1/2)D = 200 - (1/2)(200) = 200 - 100 = 100 pennies
Mia lost: 150 - (2/3)M = 150 - (2/3)(150) = 150 - 100 = 50 pennies

Therefore, Dante and Mia lost a total of 100 + 50 = 150 pennies.
