To make the first element in row 2 equal to 0, we need to perform a row operation on the matrix.

A matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns.

Matrices are commonly used in mathematics, computer programming, and other fields to represent and manipulate data, equations, and transformations.

One way to do this is to add 2 times the first row to the second row:

4  -4   0  10

0  -6   2 -16

-1  -4   7  -6

The resulting matrix has a 0 in the first element of the second row. Note that we added 2 times the first row to the second row because we want to eliminate the first element of the second row by making it zero.

The coordinates of point B on segment AC such that the ratio of AB to BC is 2 : 3 is (12 / 5, 38 / 5).

In this problem we must use the concept of segment ratios and linear algebra operations to determine the location of a point within a line segment generated by two distinct points:

B(x, y) = A(x, y) + (AB / AC) · [C(x, y) - A(x, y)]

B(x, y) = (0, 4) + (2 / 5) · [(6, 13) - (0, 4)]

B(x, y) = (0, 4) + (2 / 5) · (6, 9)

B(x, y) = (0, 4) + (12 / 5, 18 / 5)

B(x, y) = (12 / 5, 38 / 5)

In linear programming, solutions that satisfy all of the constraints simultaneously are referred to as feasible solutions. These feasible solutions represent all the possible combinations of values for the decision variables that satisfy the constraints of the problem.

The main objective of linear programming is to find the optimal feasible solution that maximizes or minimizes a given objective function. The objective function represents the goal that needs to be achieved, such as maximizing profit, minimizing cost, or maximizing efficiency.

To find the optimal feasible solution, a linear programming algorithm is used to analyze all the possible combinations of decision variables and evaluate their objective function values. The algorithm starts by identifying the feasible region, which is the area that satisfies all the constraints.

Then, the algorithm evaluates the objective function at each vertex or corner of the feasible region to find the optimal feasible solution. The optimal feasible solution is the one that provides the best objective function value among all the feasible solutions.

Therefore, In linear programming, solutions that satisfy all of the constraints simultaneously are referred to as: linear programming

In summary, linear programming involves finding feasible solutions that satisfy all the constraints of the problem, and then selecting the optimal feasible solution that provides the best objective function value.

Given that ∠ADB and ∠BDC are complimentary angles, the numerical value of a, ∠ADB and ∠BDC are 5, 25° and 65° respectively.

When two angles have measures adding to up to 90 degrees, they are called complementary .

Given that;

For complimentary angles;

m∠ADB + m∠BDC = 90°

Plug in the given values and solve for a.

( 3a + 10 ) + 13a = 90

3a + 10 + 13a = 90

10 + 16a = 90

16a = 90 - 10

16a = 80

a = 80/16

a = 5

Now, find the measure of ∠ADB and ∠BDC.

m∠ADB = ( 3a + 10 ) = 3(5) + 10 = 15 + 10 = 25°

m∠BDC = 13a = 13( 5 ) = 65°

Answer:C->-4<=X<=6

Second answer:A -4<=y<=4

Third answer: yes

According to the given graph, the domain of the function is -4 to 6, So Option C is correct

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

The graph,

Which has values of x in the interval of -4 to 6

And the value of y in the interval of -4 to 4

The value of the additional data point is 36

To find the value of the additional data point, we can use the concept of the sample mean.

Given the data set: 23, 28, 20, 33, 42, 12, 19, 50, 36, 25, 19.

The sample mean of this data set is 26.5.

To find the value of the additional data point, we can use the formula for the sample mean:

(sample mean) = (sum of all data points) / (number of data points)

In this case, we have 11 data points in the original data set. Let's denote the value of the additional data point as x.

Therefore, we can set up the equation:

26.5 = (23 + 28 + 20 + 33 + 42 + 12 + 19 + 50 + 36 + 25 + 19 + x) / 12

Multiplying both sides of the equation by 12 to eliminate the fraction, we have:

318 = 282 + x

Subtracting 282 from both sides of the equation, we find:

x = 318 - 282

An easy way to graph a linear function is to sub in any two x-values into the equation and solve for the corresponding y-values, then connect the two points with a line. I can see in the pic that you've already marked the y-intercept at -2, so you only need one more point to draw a line. Since the coefficient of x is -5/4, picking a multiple of 4 as an x-value would result in a whole number value for y, making it easier to plot. For example, sub in x = 4 into the equation and solve.

y = -5/4 (4) - 2

y = -5 - 2

y = -7

Plot the points (4, -7) and the intercept (0, -2), then connect the points with a straight line

The probability that exactly one 6 is rolled is 42.9%

Rolling a six-sided dice and an eight-sided die can yield a variety of results. The probability of rolling exactly one 6 out of the two dice is 6/14, or approximately 42.9%.

This is calculated by taking the total number of ways to roll one 6 (6) and dividing it by the total number of combinations possible (14). This means that there is a 42.9% chance of rolling one 6 when two dice are rolled.

The probability will be calculated by:

The amount of units that must be sold to a number yields a maximum profit is 600. Hence 600 units will be the correct option.

To find the maxima of any function it needs to differentiate with respect to the dependent variable and equate with zero to get stationary points.

After achieving the stationary points it needs to put on the double derivative of that function to check whether it's maxima or minima.

If the double derivative got negative then it will be maxima.

Given that function

f(x) = -0.001(x-600)² + 90

By differentiation

\($f'(x)$\) = -0.002(x - 600) + 90

Now equate with zero

-0.002(x - 600) + 90 = 0

x - 600 = 0

x = 600

Now checking the x at double derivative

\($f''(x)$\) at x = 600 it is coming out to -0.002 which is negative Hence, the 600 units will be the correct answer.

The height at time t (in seconds) of a mass, oscillating at the end of a spring, is s(t) = 300 + 16 sin t cm. We have to find the velocity and acceleration at t = π/3 s.

Let's first find the velocity of the mass. The velocity of the mass is given by the derivative of the position of the mass with respect to time.t = π/3 s
s(t) = 300 + 16 sin t cm
Differentiating both sides of the above equation with respect to time
v(t) = s'(t) = 16 cos t cm/s

Now, let's substitute t = π/3 in the above equation,
v(π/3) = 16 cos (π/3) cm/s
v(π/3) = -8√3 cm/s

Now, let's find the acceleration of the mass. The acceleration of the mass is given by the derivative of the velocity of the mass with respect to time.t = π/3 s
v(t) = 16 cos t cm/s
Differentiating both sides of the above equation with respect to time
a(t) = v'(t) = -16 sin t cm/s²
Now, let's substitute t = π/3 in the above equation,
a(π/3) = -16 sin (π/3) cm/s²
a(π/3) = -8 cm/s²
Given, s(t) = 300 + 16 sin t cm, the height of the mass oscillating at the end of a spring. We need to find the velocity and acceleration of the mass at t = π/3 s.
Using the above concept, we can find the velocity and acceleration of the mass. Therefore, the velocity of the mass at t = π/3 s is v(π/3) = -8√3 cm/s, and the acceleration of the mass at t = π/3 s is a(π/3) = -8 cm/s².
At time t = π/3 s, the velocity of the mass is -8√3 cm/s, and the acceleration of the mass is -8 cm/s².

The saddle points of the function are: (0,1,2) and (0,-1,2)

To find the saddle point(s), we need to find the critical points of the function where the partial derivatives are equal to zero or undefined.

Taking the partial derivative with respect to x, we get:

f_x = 6x² - 6 + 6y²

Setting this equal to zero, we get:

6x² - 6 + 6y^2 = 0

Simplifying, we get:

x² + y² = 1

Taking the partial derivative with respect to y, we get: f_y = 12xy

Setting this equal to zero, we get: x = 0 or y = 0

Now, we need to check the second partial derivatives to determine the nature of the critical points. Taking the second partial derivative with respect to x, we get:

f_xx = 12x

Taking the second partial derivative with respect to y, we get: f_yy = 12x

Taking the mixed partial derivative, we get:

f_xy = 12y At the point (0,1), we have:

f_xx = 0, f_yy = 0, and f_xy = 12

Since f_xx and f_yy are both zero and f_xy is nonzero, we have a saddle point at (0,1,f(0,1)).

Similarly, at the point (0,-1), we have:

f_xx = 0, f_yy = 0, and f_xy = -12

So we also have a saddle point at (0,-1,f(0,-1)).

Therefore, the saddle points of the function are: (0,1,2) and (0,-1,2)

Let X be the number of fixed points of a random permutation of n elements. A fixed point is an element that remains in the same position after the permutation. Thus, the probability that an element is fixed is 1/n, and the probability that it is not fixed is (n-1)/n.

Using the linearity of the expected value, we can calculate the expected value of X as:

E(X) = E(X1 + X2 + ... + Xn) = E(X1) + E(X2) + ... + E(Xn)

where Xi is the indicator random variable that is equal to 1 if the i-th element is fixed and 0 otherwise. Since the probability of an element being fixed is 1/n, we have E(Xi) = 1/n. Therefore,

E(X) = n * (1/n) = 1

To find the variance of X, we need to compute E(X^2) - E(X)^2. We can use the fact that X^2 = X1 + X2 + ... + Xn, where Xi is the indicator random variable that is equal to 1 if the i-th and j-th elements are both fixed and 0 otherwise. Then,

E(X^2) = E(X1 + X2 + ... + Xn)^2 = E(X1^2 + X2^2 + ... + Xn^2) + 2 E(X1X2 + X1X3 + ... + X(n-1)n)

Since there is only one way to fix two elements out of n, we have E(XiXj) = 1/(n(n-1)). Therefore,

E(X^2) = n * (1/n) + n(n-1) * (1/(n(n-1))) = 1 + 1/n

Finally, the variance of X is

Var(X) = E(X^2) - E(X)^2 = 1 + 1/n - 1^2 = 1/n

Therefore, the variance of the number of fixed elements of a randomly selected permutation of n elements is 1/n.
