Expression used for area of a rectangle is 12x² + 74x + 44 .

Its degree and classification is 2 and quadratic

and demonstration of a closure property is given by product of a polynomial is a polynomial.

Length of the rectangle = (6x + 4) units

and Width of the rectangle = (2x + 11) units.

The area of the rectangle is given by the product of its length and width,

Area = (6x + 4) × (2x + 11)

Find the product,

⇒ Area = 6x × 2x + 6x × 11 + 4 × 2x + 4 × 11

Simplifying this expression, we get,

⇒ Area = 12x² + 74x + 44

The expression that represents the area of the rectangle is 12x² + 74x + 44.

The degree of the expression 12x² + 74x + 44 is 2,

since the highest power of x is 2.

The classification of this expression is quadratic.

Part A demonstrates the closure property for polynomials because the product of two polynomials is also a polynomial.

Here, the area of the rectangle is the product of two polynomials (6x + 4) and (2x + 11).

And the result is also a polynomial (12x² + 74x + 44).

This shows that the set of polynomials is closed under multiplication.

Which is one of the defining properties of a mathematical system.

Therefore, the expression for area of a rectangle is (12x² + 74x + 44) ,

Degree and classification is 2 and quadratic and closure property is demonstrate by product of a polynomial.

By translation, the image of the triangle X is equivalent to the triangle E.

Herein we find the representation of a triangle, whose vertices are described below:

A(x, y) = (5, 5), B(x, y) = (5, 6), C(x, y) = (7, 5)

Whose image must be determined by a rigid transformation known as translation:

P'(x, y) = P(x, y) + T(x, y)

Where:

Now we proceed to determine the images of the vertices of the triangle:

A'(x, y) = (5, 5) + (4, - 3)

A'(x, y) = (9, 2)

B'(x, y) = (5, 6) + (4, - 3)

B'(x, y) = (9, 3)

C'(x, y) = (7, 5) + (4, - 3)

C'(x, y) = (11, 2)

The entrepreneur's revenue is  $2325x, entrepreneur's cost is $33,750 + $1700x and entrepreneur's profit from x sold-out performances is  $625x - $33,750

The entrepreneur's revenue from x sold-out performances is given by the formula:

Revenue = (Price per Performance) x (Number of Performances)

Revenue = $2325 x x

Revenue = $2325x

The entrepreneur's cost from x sold-out performances is given by the formula:

Cost = Overhead + (Production Cost per Performance) x (Number of Performances)

Cost = $33,750 + $1700x

The entrepreneur's profit from x sold-out performances is the revenue minus the cost:

Profit = Revenue - Cost

Profit = $2325x - ($33,750 + $1700x)

Answer:

To find out how much interest Jenny earns in one year, we can use the formula:

interest = principal x rate x time

where:

the principal is the amount of money in the savings account

rate is the interest rate per year, expressed as a decimal

time is the length of time the money is in the account, in years

In this case, Jenny's principal is $1200, the rate is 3% or 0.03 as a decimal, and the time is 1 year. Plugging these values into the formula, we get:

interest = 1200 x 0.03 x 1

interest = $36

Therefore, Jenny earns $36 in interest in one year.

Marcus jogged [tex]2\frac{1}{2}[/tex] miles over the weekend.

Marcus jogged [tex]1\frac{2}{5}[/tex] miles on Saturday and 9/10 miles on Sunday.

we first need to find a common denominator:

[tex]1\frac{2}{5}[/tex]  = 7/5

9/10 = 0.9 miles

Now, we can round each of these to the nearest 1/2:

7/5 is closer to [tex]1\frac{1}{2}[/tex] than 1, so we round to [tex]1\frac{1}{2}[/tex]

0.9 is closer to 1 than 1/2, so we round to 1

The smallest positive integer n that makes the fourth root of 56n360 an integer is n = 81.

We can start by simplifying the expression inside the fourth root:

56 * n * 360 = [tex]2^{3}[/tex] * 7 * n * [tex]2^{3}[/tex] * [tex]3^{2}[/tex] * 5

= [tex]2^{6}[/tex] * [tex]3^{2}[/tex] * 5 * 7 * n

Taking the fourth root of this expression gives:

[tex](56*n*360)^{(1/4)}[/tex] = [tex](2^{6}*3^{2}*5*7*n) ^{(1/4)}[/tex]

= [tex]2^{(6/4)}[/tex] * [tex]3^{(2/4)}[/tex] * [tex]5^{(1/4)}[/tex] * [tex]7^{(1/4)}[/tex] * [tex]n^{(1/4)}[/tex]

= 4 * [tex]3^{(1/2)}[/tex] * [tex]5^{(1/4)}[/tex] *  [tex]7^{(1/4)}[/tex] * [tex]n^{(1/4)}[/tex]

For the fourth root to be an integer, [tex]n^{(1/4)}[/tex] must be an integer, and since we want n to be as small as possible, we want  [tex]n^{(1/4)}[/tex] to be as small as possible.

The smallest possible value of n that makes  [tex]n^{(1/4)}[/tex]an integer is when n is a fourth power of a prime number. Therefore, we can let n = [tex]p^{4}[/tex], where p is the smallest prime number that makes the expression under the fourth root an integer.

From the expression above, we can see that p must be a factor of 7 and [tex]35^{2}[/tex] in order to make the expression under the fourth root an integer. The smallest prime factor of 7 and [tex]35^{2}[/tex] is 3, so we can let p = 3. Then:

n =  [tex]p^{4}[/tex] = [tex]3^{4}[/tex] = 81

The distribution is roughly symmetric, we can use the mean as a measure of center and the standard deviation as a measure of spread.

The distribution of miles ran each week by Elisa is relatively symmetric and centered around 30 miles per week, with a relatively tight spread of about 2.3 miles per week.

We have,

a.

Since the distribution is roughly symmetric, we can use the mean as a measure of center and the standard deviation as a measure of spread.

However, the distribution also has some slight right-skewness, so we may want to consider using the median instead of the mean, depending on the context and purpose of the analysis.

b.

The mean of the distribution is:

= (28 + 29 + 30 + 31 + 32 + 33 + 34)/7

= 30.1

So the center of the distribution is around 30 miles per week.

The standard deviation of the distribution is approximately 2.3 miles per week, which tells us that the spread of the distribution is relatively tight.

Alternatively, we could use the median as a measure of the center.

Since there are 7 data points, the median is the average of the 4th and 5th values (30 and 31):

= (30 + 31)/2

= 30.5

So the center of the distribution is also around 30 miles per week using the median.

Thus,

The distribution is roughly symmetric, we can use the mean as a measure of center and the standard deviation as a measure of spread.

222 gallons of milk containing 7% butterfat and 111 gallons of milk containing 4% butterfat must be used to obtain 333 gallons of milk containing 6% butterfat.

Let's assume that x gallons of milk containing 7% butterfat are needed, and y gallons of milk containing 4% butterfat are needed to obtain 333 gallons of milk containing 6% butterfat.

We can set up two equations to represent the given information:

Equation 1: x + y = 333

Equation 2: 0.07x + 0.04y = 0.06(333)

Simplifying Equation 2, we get:

0.07x + 0.04y = 19.98

Multiplying both sides of Equation 1 by 0.04, we get:

0.04x + 0.04y = 13.32

Subtracting this equation from Equation 2, we get:

0.03x = 6.66

Dividing both sides by 0.03, we get:

x = 222

Substituting x = 222 into Equation 1, we get:

222 + y = 333

y = 111

Therefore, 222 gallons of milk containing 7% butterfat and 111 gallons of milk containing 4% butterfat must be used to obtain 333 gallons of milk containing 6% butterfat.
