The lateral and the total surface area of the rectangular pyramid are 182 square cm and  278 square cm

From the question, we have the following parameters that can be used in our computation:

Length = 6 cm

Width = 8 cm

Height = 6.5 cm

The lateral surface area of the rectangular pyramid is calculated as

LA = 2 *(L + W)H

So, we have

LA = 2 *(6 + 8) * 6.5

Evaluate

LA = 182

The total surface area of the rectangular pyramid is calculated as

TA = 2 * (LW + LH + HW)

So, we have

TA = 2 * (8 * 6 + 8 * 6.5 + 6.5 * 6)

Evalaute

TA = 278

Hence, total surface area of the rectangular pyramid is 278 square cm

Answer:

Step-by-step explanation:

If 11 flights were sampled with an 85% on-time arrival rate, the number of flights from the sample that arrived on time would be estimated to be 9.35, which would round to 9 flights.

This can be solved by:

(0.85x11)= 9.35

Since there can't be .35 of a flight, we would round to the nearest whole number, which would just be 9.

The final answer= 9 flights

The first 6 terms of the given sequences are  for A: 1, 2, 2, 4, 8, 16

for B: 5, 5, 17, 59, 177, 521, and for C: 2, 1, 3, 6, 15, 45

A. The 1st sequence is a geometric sequence, where each term is the product of the two preceding terms. The 1st term is 1, the 2nd term is 2, and the rest of the terms are calculated as below:

a3 = a1 * a2 = 1 * 2 = 2

a4 = a2 * a3 = 2 * 2 = 4

a5 = a3 * a4 = 2 * 4 = 8

a6 = a4 * a5 = 4 * 8 = 16

So, the first six terms of the sequence are 1, 2, 2, 4, 8, and 16.

B. The 2nd sequence can be calculated by using the formula

an = 2 * an - 1 + 3 * an - 2 for n greater than or equal to 2. The 1st term a1 is 5 and the 2nd term a2 is 5, so the rest of the terms are calculated as below:

a3 = 2 * a2 + 3 * a1 = 2 * 5 + 3 * 5 = 17

a4 = 2 * a3 + 3 * a2 = 2 * 17 + 3 * 5 = 59

a5 = 2 * a4 + 3 * a3 = 2 * 59 + 3 * 17 = 177

a6 = 2 * a5 + 3 * a4 = 2 * 177 + 3 * 59 = 521

So, the first six terms of the sequence are 5, 5, 17, 59, 177, and 521.

C. The 3rd sequence follows the formula gn = n * gn - 1 + gn - 2. The 1st term g1 is 2 and the 2nd term g2 is 1, so the rest of the terms are calculated as below:

g3 = 3 * g2 + g1 = 3 * 1 + 2 = 5

g4 = 4 * g3 + g2 = 4 * 5 + 1 = 21

g5 = 5 * g4 + g3 = 5 * 21 + 5 = 110

g6 = 6 * g5 + g4 = 6 * 110 + 21 = 786

So, the first six terms of the sequence are 2, 1, 3, 6, 15, and 45.

The value of x is 9.

According to the segment addition postulate, the sum of the lengths of two segments is equal to the length of the entire segment.

In this case, GH + HI = GI.

GH = 4x - 6

HI = 2x + 2

GI = 50

Using the segment addition postulate, we can write the equation:

GH + HI = GI

Substituting the given values:

4x - 6 + 2x + 2 = 50

Combining like terms:

No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.

According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.

If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.

Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.

However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.

Therefore,  if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.

Answer:

The selling price of the diamond necklace at Shamin Jewelers after 10% discount is:

$442 * 0.9 = $397.80

The selling price of the same necklace at the competitor's store after 34% and 14% discount is:

$527 * 0.66 * 0.86 = $247.08

So, Shamin Jewelers needs to offer an additional discount to meet the competitor's price:

$397.80 - $247.08 = $150.72

To calculate the additional rate of discount, we divide the difference by the original selling price at Shamin Jewelers and multiply by 100:

($150.72 / $442) * 100 = 34.11%

Therefore, Shamin Jewelers must offer an additional 34.11% discount to meet the competitor's price.

Using Gaussian elimination, the solution to the given system of equations is given as follows:

x = 5, y = -11, z = 3.

A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.

For this problem, the variables are x, y and z, and the system is given as follows:

There are multiple ways in which a system can be solved, and for this one, Gaussian elimination will be used.

The first step is writing the augmented matrix of the system, as follows:

\(\left[\begin{array}{cccc}2&-1&4&33\\1&2&-3&-26\\-5&-3&5&23\end{array}\right]\)

Then, the first column, which is equivalent to be coefficient of y, has to be of zero on the second and on the third row, hence:

The updated matrix will be given by:

\(\left[\begin{array}{cccc}2&-1&4&33\\0&5&-10&-85\\0&-11&30&211\end{array}\right]\)

Then, the second column, equivalent to the coefficient of y, on the third row has to be zero, hence:

R3 -> 11R2 + 5R3.

Then the matrix is:

\(\left[\begin{array}{cccc}2&-1&4&33\\0&5&-10&-85\\0&0&40&120\end{array}\right]\)

From each row of the system, from bottom up, we find the variables, as follows:

40z = 120

z = 120/40

z = 3.

5y - 10z = -85

5y - 30 = -85

5y = -55

y = -11.

2x - y + 4z = 33

2x + 11 + 12 = 33

2x = 10

x = 5.

Hence the solution for the system is:

x = 5, y = -11, z = 3.

By graphing or visualizing the parabolic shape, we can observe where the graph intersects the x-axis, which represents the solutions to the equation. In this case, the solutions are x = -3 and x = 1.

To solve the quadratic equation x^2 + 2x - 3 = 0 by graphing, we can plot the graph of the equation and find the x-values where the graph intersects the x-axis.

First, let's rearrange the equation to the standard form: x^2 + 2x - 3 = 0.

We can create a graph by plotting points for different values of x and then connecting them. However, I can describe the process and the key points on the graph.

1. Find the x-intercepts: These are the points where the graph intersects the x-axis. To find them, set y (the equation) equal to zero and solve for x:

  0 = x^2 + 2x - 3.

  This quadratic equation can be factored as (x + 3)(x - 1) = 0.

  Therefore, x = -3 or x = 1.

2. Plot the points: Plot the points (-3, 0) and (1, 0) on the graph. These are the x-intercepts.

3. Draw the graph: The graph of the equation x^2 + 2x - 3 = 0 is a parabola that opens upward. It will pass through the x-intercepts (-3, 0) and (1, 0).

To find the difference between the actual quotient and the estimated quotient of 54,114 ÷ 29, we need to first calculate the actual quotient and then the estimated quotient.

Actual quotient:

Dividing 54,114 by 29, we get:

54,114 ÷ 29 = 1,866.3448275862068965517241379 (approximated to 28 decimal places)

Estimated quotient:

Rounding the dividend, 54,114, to the nearest thousand gives us 54,000. Rounding the divisor, 29, to the nearest ten gives us 30. Now, we can perform the division with the rounded values:

54,000 ÷ 30 = 1,800

Difference between actual and estimated quotient:

Actual quotient - Estimated quotient = 1,866.3448275862068965517241379 - 1,800 = 66.3448275862068965517241379

1 : 2 (for every 1 pen there is 2 copy)

We know that

Reese needs 1/4 yards of blue ribbon for every 5/8 yards of gold ribbon.

To know the total blue ribbon she would need for each yard of gold ribbon, we use the following proportion.

The magnitude or size of a mathematical object is a property which determines whether the object is larger or smaller than other objects of the same kind.

Here, given values;

a = (-7, 3)  and b = (-2, -12)

Now, c = a + b

        c = (-7, 3) + (-2, -12)

        c = (-9, -9)

Now, |c| = √(9²+9²)

         |c| = 9√2

Now, tan θ = |y/x|

        tan θ = |-9/-9|

       tan θ = 1
