Here's a MATLAB code to find the sum and product of the diagonal elements of a given matrix `A`, as well as an example execution for `A = ones(5)`:

```matlab

% Define the matrix A

A = ones(5);

% Get the size of the matrix

[n, ~] = size(A);

% Initialize variables for sum and product

diagonal_sum = 0;

diagonal_product = 1;

% Calculate the sum and product of diagonal elements

for i = 1:n

   diagonal_sum = diagonal_sum + A(i, i);

   diagonal_product = diagonal_product * A(i, i);

end

% Display the results

disp("Sum of diagonal elements: " + diagonal_sum);

disp("Product of diagonal elements: " + diagonal_product);

```

Example execution for `A = ones(5)`:

```

Sum of diagonal elements: 5

Product of diagonal elements: 1

```

In this example, `A = ones(5)` creates a 5x5 matrix filled with ones. The code then iterates over the diagonal elements (i.e., elements where the row index equals the column index) and accumulates the sum and product. Finally, it displays the computed sum and product of the diagonal elements.

Magnitude of impulse is I = FΔ t

What is impulse?

The concept of an impulse in it's most elementary kind could be a force integrated over a time. For a force with a relentless magnitude, we are able to notice the magnitude of the impulse by multiplying the magnitude of the force by the time that force is exerted.

Main body:

If the force is not constant, we simply integrate the force function over the set time period.

The direction of the impulse vector will be the direction of the force vector and the units will be a force times a time

Constant Magnitude Force:

J^=F^∗t

Impulse = Force × (final time – initial time)

Impulse = Force × Δt

I = F × Δt

Hence the magnitude of impulse is I = FΔ t

The number of zeros which this graphed polynomial function have is: B. 3.

A polynomial function can be defined as a mathematical expression which comprises intermediates (variables), constants, and whole number exponents with different numerical value, that are typically combined by using mathematical operations.

Additionally, a polynomial graph simply refers to a type of graph that is commonly used for the representation of only positive (non-negative) integer exponents of a variable in an equation.

This ultimately implies that, a polynomial graph touches the x-axis at zeros, roots, solutions, x-intercepts, and factors with even multiplicities.

In this context, we can reasonably and logically deduce that the zeros of a polynomial function are all of the values (x-intercepts) on the x-coordinate that makes this polynomial function equal to zero and these include the following:

Zeros = (-2, 0)

Zeros = (-1, 0)

Zeros = (1, 0)

Answer: the total of the three- digit numbers which will satisfy the property that the middle digit is the average of the first and last digits is 45

Step-by-step explanation:

taking 1,2,3,4,5,6,7,8,9 as the numbers to form the first digits, we see

1 will take an odd number as the last digit so that there is a whole number as an average middle digit. the only numbers are 1,3,5,7,9

all the other odd numbers that is, 3,5,7,9 will also take 1,3,5,7,9 as their last digits

looking at the even numbers as the first digits that is 2,4,6,8, they will take 0,2,4,6,8 as their last digits

by this we see that we are forming five last digits to the first nine digits so that the property of the middle term becomes the average of the first and last digits

the total three-digit number which satisfy the property therefore, we get 9 as the first digits and five as the last digits therefore this gives a total of

$499 x (1+10%) = $ 548.9

The expected value of the product of two independent random variables X and Y is equal to the product of their individual expected values, given that the expected values of X and Y exist.

Let X and Y be two independent random variables. Then, the expected value of the product XY is given by:

E[XY] = ∫∫ xy fX(x) fY(y) dx dy

where fX(x) and fY(y) are the probability density functions of X and Y, respectively. Since X and Y are independent, their joint probability density function is given by:

fXY(x,y) = fX(x) fY(y)

Thus, the expected value of XY can be written as:

E[XY] = ∫∫ xy fX(x) fY(y) dx dy = ∫∫ xy fXY(x,y) dx dy

Now, we can use the linearity of expected value to split up the integral:

E[XY] = ∫∫ xy fXY(x,y) dx dy = ∫∫ x fX(x) y fY(y) dx dy

      = (∫ x fX(x) dx) (∫ y fY(y) dy) = E[X] E[Y]

Therefore, we have shown that E[XY] = E[X] E[Y], given that X and Y are independent and that the expected values of X and Y exist.

The difference between  the numbers 9.1 x 10⁹ and 7.8 x 10⁸ is 8.32 x 10⁹.

Given numbers are 9.1 x 10⁹ and 7.8 x 10⁸

Let's align the exponents by moving the decimal point to the right in the number with the smaller exponent, while incrementing the exponent accordingly.

We need to move the decimal point and increment the exponent of 7.8 x 10⁸ to match the exponent of 9.1 x 10⁹

7.8 x 10⁸ can be rewritten as 0.78 x 10⁹

Now that the exponents are aligned, we can subtract the coefficients:

9.1 x 10⁹ - 0.78 x 10⁹

= (9.1 - 0.78) x 10⁹

= 8.32 x 10⁹

Therefore, the difference between 9.1 x 10⁹ and 7.8 x 10⁸ is 8.32 x 10⁹.

Given linear inequalities in the graph are,

\(y\geq -\frac{1}{3}x+2\)

y < 2x + 3

Here shaded area above the solid line represents the inequality,

\(y\geq -\frac{1}{3}x+2\)

And shaded area on the right side of the dotted line represents the solution set of the inequality,

y < 2x + 3

And the solution set of the system of linear inequalities will be represented by the common area of these inequalities.

Therefore, ordered pairs (2, 2), (3, 1) and (4, 2) will lie in the common shaded area.

Answer: 9 units

Step-by-step explanation:

The dot products of A = (1, 1, -1) and B = (3, 5, 8) are zero, so the cross product axb is orthogonal to both vectors A and B.

Step 1: Write down the components of the vectors A and B.
A = (A1, A2, A3) = (1, 1, -1)
B = (B1, B2, B3) = (3, 5, 8)

Step 2: Compute the cross product axb using the formula:
axb = (A2*B3 - A3*B2, A3*B1 - A1*B3, A1*B2 - A2*B1)

Step 3: Substitute the components of A and B into the formula.
axb = (1*8 - (-1)*5, (-1)*3 - 1*8, 1*5 - 1*3)

Step 4: Simplify the expression.
axb = (8 + 5, -3 - 8, 5 - 3)

Step 5: Calculate the final components of the cross product axb.
axb = (13, -11, 2)

Now, to verify if the cross product is orthogonal to both A and B, we will check if the dot product of axb with A and B is zero.

Step 6: Calculate the dot product of axb with A and B.
(axb·A) = (13*1 + (-11)*1 + 2*(-1))
(axb·B) = (13*3 + (-11)*5 + 2*8)

Step 7: Simplify the expressions.
(axb·A) = (13 - 11 - 2)
(axb·B) = (39 - 55 + 16)

Step 8: Calculate the final dot product values.
(axb·A) = 0
(axb·B) = 0

Since both the dot products are zero, the cross product axb is orthogonal to both vectors A and B.

Answer:60 per hour

Step-by-step explanation: you divide 180 by 3

The ratio that represent the quantities that are proportional to 15/10 and 10/15 are 3/2 and 2/3.

In mathematics, a ratio is the number of times one statistic equals another. A ratio can include any number, such as a count of people or products, or measurements of lengths, weights, and time, among other things.

Both numbers must be positive in most cases. As a result, a ratio can be defined as an ordered pair of integers, a fraction with the first and second numbers in the denominator, or the value represented by this fraction. Ratios of counts provided by (non-zero) two numbers are rational and, in some cases, natural numbers.

From the given equation we can see that the value of the proportion is given by 15/10 which can be simplified to 3/2 with common factor of 5.

Again the value of the proportion is given by 10/15 which can be simplified to 2/3 with common factor of 5.

hence the equal proportions will be 3/2 and 2/3.
