Answer:

The answer is 7

Step-by-step explanation:

The main answer is O(n^3), indicating that the number of flops required to solve the system using Gaussian elimination on an upper Hessenberg matrix is cubic in the size of the matrix.

When solving the system of equations Ax = b using Gaussian elimination, the number of floating point operations (flops) required can be determined by the number of multiplications and divisions performed. In the case of an upper Hessenberg matrix A, the matrix has zeros below the first subdiagonal, which allows for a more efficient elimination process compared to a general matrix.

To solve the system, Gaussian elimination involves eliminating the unknowns below the diagonal one row at a time. In each elimination step, we perform a row operation that eliminates one unknown by subtracting a multiple of one row from another. Since the matrix is upper Hessenberg, the number of operations required to eliminate one unknown is proportional to the number of non-zero entries in the subdiagonal of that row.

Considering that the subdiagonal of each row contains at most two non-zero entries, the number of operations required to eliminate one unknown is constant. Therefore, the total number of operations required to solve the system using Gaussian elimination on an upper Hessenberg matrix is proportional to the number of rows, n, multiplied by the number of operations required to eliminate one unknown, resulting in O(n^3) flops.

How do you calculate the ratio?

The steps of calculating a ratio are as follows:

Establish the ratio's function. Choosing what you want your ratio to show should be your first step. Every ratio will use a different set of data, so you need to make sure you are using the right data to provide you with the information you need.

Organize your formula. Ratios contrast two figures by ordinarily dividing them. A/B would be your formula if you were comparing one data point (A) to another data point (B). This indicates that you are multiplying information A by information B. For instance, your ratio will be 5/10 if A is 5 and B is 10.

Make the equation work. To calculate your ratio, divide data A by data B.

Let the present age of pete be P and claire be C.

According to question:

Two years ago pete was three times as old as his cousin claire.

⇒ P - 2 = 3(C - 2)

⇒ P - 2 = 3C - 6

⇒ P = 3C - 6 + 2

⇒ P = 3C - 4 ..................(1)

Also,  2 years before that, pete was four times as old as claire.

⇒ P - 4 = 4(C - 4)

⇒ P - 4 = 4C - 16

⇒ P = 4C - 16 + 4

⇒ P = 4C - 12 ..................(2)

Equating eq(1) and eq(2)

4C - 12 = 3C - 4

4C - 3C = -4 + 12

C = 8

Substitute the value of C in eq(1) we get,

P = 3(C) - 4 = 3(8) - 4 = 24 - 4 = 20

Let x be the number of years until Pete is twice as old as his cousin.

20 + x = 2(8 + x)

20 + x = 16 + 2x

20 - 16 = 2x - x

4 = x

Therefore, after 4 years ratio of their ages be 2 : 1

The regression analysis can be used to fit a parabola to a set of data and plot the parabola and data to visualize the relationship between x and y. By using regression analysis, we can find the best-fitting parabola and gain insights into the underlying trends in the data.

Regression analysis can be used to fit a parabola to a set of data by finding the coefficients of the quadratic equation y = ax^2 + bx + c that best fit the data. This can be done using least squares regression, where the sum of the squared differences between the predicted values of y and the actual values of y is minimized.

To plot the parabola and the data, we can use a graphing calculator or a spreadsheet program like Excel. First, we input the data points into the spreadsheet and then use the regression analysis tool to find the coefficients a, b, and c that best fit the data. Once we have the coefficients, we can plot the parabola using the equation y = ax^2 + bx + c.

After plotting the parabola, we can overlay the data points to see how well the parabola fits the data. If the parabola fits the data well, the data points should be clustered around the curve of the parabola. If the parabola does not fit the data well, there may be outliers or other factors that are affecting the relationship between x and y.

The value of x in the given right triangle can be found with help of trigonometric-ratios, given an angle 16° and hypotenuse 37 units is 35.566657. On rounding off to nearest tenths we get 35.6 units.

What are trigonometric-ratios?

In a given right triangle, the ratios of different sides are represented as six trigonometric ratios which are cosine,sine,cosecant,cot,secant and tan.

Sin of an angle=\(\frac{side opposite to the angle}{hypotenuse of triangle}\)

Cosine of an angle=\(\frac{side adjacent to the angle}{hypotenuse of the triangle}\)

tan of an angle= \(\frac{side opposite to the angle}{side adjacent to the angle}\)

And cosecant, secant and cot are the reciprocals of sine, cosine & tan respectively.

Here,on naming the given right triangle we can see that

∠A = 16° , AC=37 units and Side AB= x units

Applying cosine of angle  16°, we get

cos A=\(\frac{side adjacent to the angle}{hypotenuse of the triangle}\)

Cos 16°=\(\frac{side adjacent to the angle}{hypotenuse of the triangle}\)

Cos  16°= \(\frac{AB}{AC}\)

0.961261= \(\frac{AB}{AC}\) {Cos  16°=0.961261}

0.961261=\(\frac{x}{37}\)    {AB=x and AC=37}

           x = 0.961261 (37)

           x = 35.566657

Step-by-step explanation:

To maximize the revenue store should charge rental fee of $7 for a movie .

Let x be the number of $1 increases in the rental fee

Let p(x) be the price of renting a movie after x increases,

And let q(x) be the quantity of movies rented per week after x increases.

The rental fee is $3, we have q(0) = 55.

For each additional $1 increase in the rental fee, the store loses 11 rentals per week.

This means that,

q(x) = q(0) - 11x

The revenue generated from renting movies per week is equal to the price per movie times the number of movies rented,

R(x) = p(x)q(x)

Maximize the revenue with respect to x.

Express R(x) in terms of p(x),

Take the derivative with respect to p(x),

R(x) = p(x)q(x)

      = p(x)(55 - 11x)

      = 55p(x) - 11x p(x)

Taking the derivative with respect to p(x), we get,

d(R)/d(p(x)) = 55 - 11x

Setting this equal to zero, we get,

⇒55 - 11x = 0

⇒x = 5

Store should increase the rental fee by $5.

The new rental fee would be,

p(5) = $3 + $5

       = $8

And the quantity of movies rented per week would be,

q(5) = 55 - 11(5)

       = 0

Since the quantity of movies rented per week would be zero.

If the rental fee is increased by $5,

⇒ store should not increase the rental fee by that much.

Instead, the store should increase the rental fee by $4,

so the new rental fee would be,

p(4) = $3 + $4

      = $7

And the quantity of movies rented per week would be,

q(4) = 55 - 11(4)

       = 11

Therefore, the store should charge $7 per movie to maximize their revenue.

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%

because the re adding of the dollars

If Fred and Wilma borrows $200,000 to purchase a home with an interest rate of 7.5 percent for 30 years and a monthly payment of $1,398, how much total interest will they pay over the life of the loan (30 years) is option (C)  $303,280.

The total interest paid over the life of the loan can be calculated by subtracting the principal amount borrowed from the total amount repaid. The total amount repaid is the monthly payment multiplied by the number of months (30 years * 12 months per year). Given that Fred and Wilma borrowed $200,000 with a monthly payment of $1,398, we can calculate the total interest paid.

Total amount repaid = Monthly payment * Number of months

Total interest paid = Total amount repaid - Principal amount

Total amount repaid = $1,398 * (30 years * 12 months per year)

Total amount repaid = $1,398 * 360

Total interest paid = ($1,398 * 360) - $200,000

Calculating this expression gives us:

Total interest paid = $503,280 - $200,000

Total interest paid = $303,280

Therefore, Fred and Wilma will pay a total interest of $303,280 over the life of the loan.

To calculate the total interest paid over the life of the loan, we subtract the principal amount borrowed from the total amount repaid.

The total amount repaid is obtained by multiplying the monthly payment by the number of months, which is 30 years multiplied by 12 months per year. In this case, the monthly payment is $1,398.

Total amount repaid = $1,398 * (30 years * 12 months per year)

Total amount repaid = $1,398 * 360

Total amount repaid = $503,280

Next, we calculate the total interest paid by subtracting the principal amount borrowed ($200,000) from the total amount repaid.

Total interest paid = $503,280 - $200,000

Total interest paid = $303,280

Therefore, Fred and Wilma will pay a total interest of $303,280 over the life of the loan. The correct answer is option c. $303,280.

The perceptual constancy that recognizes objects despite changes in angle, distance, or illumination is shape constancy.

Shape constancy is a perceptual phenomenon where our brain recognizes and maintains the perceived shape of an object, even when it is viewed from different angles or distances. It allows us to identify and understand objects based on their familiar shapes, regardless of the variations in how they appear due to changes in viewing conditions. Shape constancy helps us perceive objects as having a consistent shape, providing stability and continuity in our visual perception. The perceptual constancy that the brain recognizes, despite the angle, distance, or illumination of how the object is viewed, is size constancy. Size constancy refers to the ability to perceive the true size of an object regardless of its distance from the observer or the viewing angle. Our brain compensates for changes in distance and angle to maintain a consistent perception of the object's size. This allows us to accurately perceive the size of objects even when they appear smaller or larger due to their distance or perspective.

The dimensions of the rectangular poster are 9 inches by 22 inches.

Let's assume the width of the rectangular poster is x inches.

According to the given information, the length of the poster is 4 more inches than two times its width. So, the length can be expressed as 2x + 4 inches.

The formula for the area of a rectangle is length × width. In this case, the area is given as 198 square inches.

Therefore, we have the equation:

(2x + 4) × x = 198

Expanding the equation:

\(2x^2 + 4x = 198\)

Rearranging the equation to standard quadratic form:

\(2x^2 + 4x - 198 = 0\)

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. Let's use the quadratic formula:

x = (-b ± √\((b^2 - 4ac\))) / (2a)

Plugging in the values:

x = (-4 ± √\((4^2 - 4(2)(-198)))\) / (2(2))

x = (-4 ± √(16 + 1584)) / 4

x = (-4 ± √1600) / 4

x = (-4 ± 40) / 4

Simplifying:

x = (-4 + 40) / 4 = 9

x = (-4 - 40) / 4 = -11

Since we are dealing with dimensions, the width cannot be negative. Therefore, the width of the poster is 9 inches.

Substituting the value of x back into the length equation:

Length = 2x + 4 = 2(9) + 4 = 18 + 4 = 22 inches
