According to the calculations we can conclude that Rosa can play 21 more minutes on Monday.

If 9 minutes represents 30% of the time Rosa can play video games, we can use proportional reasoning to find the total time she can play. Let x be the total time she can play in minutes.

9 / x = 30 / 100

We might cross-multiply and simplify to find x's value:

9 * 100 = 30 * x

900 = 30x

x = 900 / 30

x = 30

So Rosa can play a total of 30 minutes each day.

To find how many more minutes she can play on Monday, we subtract the time she has already played from the total time:

30 - 9 = 21

Therefore, Rosa can play 21 more minutes on Monday.

The ratio of the height of the smaller prism to the height of the larger prism is 1:sqrt(27).

what is prism?

A prism is a geometric solid that has two parallel and congruent polygonal bases, and the sides connecting the bases are parallelograms. These parallelograms are typically rectangles, but they can also be squares or rhombuses. A prism can be named based on the shape of its base, such as a rectangular prism, triangular prism, hexagonal prism, etc.

Since the prisms are similar, their corresponding sides are proportional. In particular, the ratio of the heights of the prisms is the same as the ratio of their volumes.

Let the height of the smaller prism be h1 and the height of the larger prism be h2. Let the volume of the smaller prism be V1 = 15 cm^3 and the volume of the larger prism be V2 = 405 cm^3. Then:

V1/V2 = (h1^2 * 5) / (h2^2 * 5)

V1/V2 = h1^2 / h2^2

sqrt(V1/V2) = h1 / h2

Substituting the given values, we get:

sqrt(15/405) = h1 / h2

sqrt(1/27) = h1 / h2

1/sqrt(27) = h1 / h2

Therefore, the ratio of the height of the smaller prism to the height of the larger prism is 1:sqrt(27), or approximately 1:5.2.

Karen and Wayne will need to make monthly payments of $66.39 for 3 years to pay off the loan for their new refrigerator for a given sales tax.

The add-on interest loan formula can be used to determine the monthly payment:

(Loan amount + Interest) / the number of payments equals a payment.

We must first determine the refrigerator's total cost, including sales tax:

Final price is $1,598 plus 5% of $1,598.

$1,677.90 is the total price.

Secondly, we must determine the loan's interest rate:

Interest is calculated as Loan Amount * Addition Rate. Ages in years

Interest equals $702.25 when $1,677.90 multiplied by 0.14 by three.

When interest is included, the total loan amount is:

Loan amount = Purchase price plus interest

Total of the loan: $1,677.90 plus $702.25

Amount borrowed: $2,380.15

In the end, we can figure out the monthly payment:

Payment: ($2,380.15) divided by (3 years * 12 months/year) =

Hi! Based on the given information and without a visual of the graph, I will provide a general answer using the terms provided. Please note that an accurate response may require additional information or context.

The slope of the line of best fit indicates the rate of change in the value of the house over time, and a positive slope signifies that the value has increased. However, the y-intercept of the line of best fit does not necessarily mean that it cost $9,994 to build the house.

The standard deviation of the sampling distribution of all samples is 0.057.

What is the standard deviation?

The standard deviation is a measurement of how much a group of values vary or are dispersed. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

Here, we have

Given: In 2019, the average high school GPA for incoming University of Maryland freshmen was 4.32 with a standard deviation of 0.285. Suppose UMD freshmen are randomly assigned into groups of 25.

We have to find the standard deviation of the sampling distribution of all samples.

Let x = High-school GPA scores of students in 2019.

E(x) = 4.32, S.D(x) = 0.285, n = 25

Suppose we consider the sampling distribution of the sample mean of all these samples, then we have

E(x) = 4.32

S.D(x) = 0.285/√25

= 0.057

Hence, the standard deviation of the sampling distribution of all samples is 0.057.

In Geometry, a dilation can be defined as a type of transformation which typically changes the size of a geometric shape, but not its shape.

In this exercise, we would use an online graphing calculator to plot the image of ABC after a dilation by a scale factor of 2 centered at P.

Based on the image (see attachment), we can logically deduce that each vertex is 2 times as far from center P as the original vertex and each segment is 2 times as long as the original:

Side length A'C' = 8.2 × 2 = 16.4

Side length A'B' = 5.0 × 2 = 10.0

The graph of the original triangle and the after the dilation are shown below:

Triangle dilation graph 8.

Dilation refers to the process of expanding or stretching an object or a space in one or more directions. In mathematics, dilation is a geometric transformation that changes the size of an object or a figure by either enlarging or reducing its dimensions, while preserving its shape and orientation.

In the context of image processing and computer vision, dilation is an operation that is commonly used to enhance and extract features from images. It involves convolving an image with a small structuring element or kernel, which slides over the image and replaces each pixel with the maximum value within the kernel.

For a dilation with a scale factor of 0.5 and centered at the origin, each coordinate of the triangle will be multiplied by 0.5. Thus:

J(8,0) will become J'(4,0)

L(-2,0) will become L'(-1,0)

K(4,4) will become K'(2,2)

The graph of the original triangle and the image after the dilation are shown below:

Triangle dilation graph 6

For a dilation with a scale factor of 2 and centered at the point (8,3), each coordinate of the triangle will be multiplied by 2 and then translated by the vector (8,3). Thus:

we have shown that [tex]$(a^m)^n = a^{mn}$[/tex] for all [tex]$a \in G$[/tex] and [tex]$m, n \in \mathbb{Z}$[/tex].

To prove that in a group G, [tex]$(a^m)^n = a^{mn}$[/tex] for all [tex]$a \in G$[/tex] and [tex]$m, n \in \mathbb{Z}$[/tex], we need to show that both sides of the equation are equal.

Answer:

b factors of 4x²-49=(2x-7) and (2x+7)

The general solution to the differential equation is M = (1/2)n² + Bn, where B is an arbitrary constant.

In calculus, differentiation is a process of finding the rate at which a function changes with respect to its input variable. It is the process of finding the derivative of a function, which represents the slope of the tangent line to the graph of the function at a given point.

The derivative of a function f(x) at a point x=a is denoted as f'(a) and is defined as the limit of the difference quotient as the interval between a and a+h approaches zero, where h is a small nonzero number.

The process of differentiation involves applying differentiation rules or formulas, which are a set of rules that make it easier to find the derivative of various functions. Some of the common rules include the power rule, product rule, quotient rule, and chain rule.

To solve the given differential equation:

[tex]\frac{d^{2}M }{dn^{2} } + 2n\frac{dM}{dn} =n[/tex]

We can assume a solution of the form:

[tex]M= An^{p}[/tex]

where A and p are constants to be determined.

Taking the first derivative of M with respect to n, we get:

[tex]\frac{dM}{dn} = Apn^{p-1}[/tex]

Taking the second derivative of M with respect to n, we get:

[tex]\frac{d^{2}M }{dn^{2} }= A(p)(p-1)n^{p-2}[/tex]

Substituting these expressions into the original differential equation, we get:

[tex]A(p)(p-1)n^{p-2} + 2Apn^{p-1}= n[/tex]

Simplifying, we get:

[tex]A(p)(p-1)n^{p-2} + 2Apn^{p}=n^{p+1}[/tex]

Since this equation must hold for all values of n, we can equate the coefficients of each power of n to get two equations:

A(p)(p-1) = 0

2Ap = 1

From the first equation, we get:

p = 0 or p = 1

If p = 0, then M = A, a constant. Substituting into the differential equation, we get:

0 = n

This is not true for all values of n, so p cannot be 0.

If p = 1, then M = An. Substituting into the differential equation, we get:

2An + 2nA = n

Simplifying, we get:

A = 1/2

Therefore, the solution to the differential equation is:

M = (1/2)n² + Bn

where B is a constant of integration.

Thus, the general solution to the differential equation is:

M = (1/2)n² + Bn

where B is an arbitrary constant.
