Answer:

m = 18/4 = 9/2 = 4.5

Step-by-step explanation:

Notice that the line passes through (0, 0) and (4, 18).  Thus, its 'rise' is 18 - 0, or 18, and its 'run' is 4 - 0, or 4, and the slope (which is the desired constant of proportionality) is m = 18/4 = 9/2 = 4.5             This is Answer B

The function that models the area A of the rectangle is A=10H-H².

The rectangle is a quadrilateral.  The classification for quadrilaterals is given by the length of sides and angles. For a rectangle,  the opposite sides are equal and parallel and their interior angles are equal to 90°.

A rectangle is a quadrilateral that has 4 sides called: base and height. Due to its characteristics, the rectangle presents two bases (B) and two heights (H).

The perimeter of a geometric figure is the sum of its sides. Thus, for a rectangle, the perimeter can be calculated from equation 2B+2H.

The area of a rectangle can be found for the formula : B*H, where B = base and H =height.

For this question:

   Perimeter = 20 ft

From the perimeter, you have the following equation:

2B+2H=P

2B+2H=20

Then,

2B=20-2H , dividing all terms by 2

B=10-H

Like the area (A) is given by B*H, you will have:

A=B*H

A=(10-H)*H

A=10H-H²

Gregs's mom baked 24 cookies, while Vinnie's mom baked 36 cookies. Brad's mom baked twice as much as Greg's mom, resulting in a total of 48 cookies. The total number of cookies that were baked is found by adding the number of cookies that each mom baked:

24 + 36 + 48 = 108.

The cookies can be divided into 3 groups of 36, 4 groups of 27, 6 groups of 18, 9 groups of 12, 12 groups of 9, 18 groups of 6, 27 groups of 4, or 36 groups of 3 cookies. Since there are more than 100 words required, let's talk about the importance of fractions and equivalent ratios.

In conclusion, Greg's mom baked 24 cookies, Vinnie's mom baked 36 cookies, and Brad's mom baked 48 cookies, resulting in a total of 108 cookies. The cookies can be divided into fractions or equivalent ratios to distribute them evenly among the children.

Step-by-step explanation:

Answer:

                y - 2 = ¹/₃(x - 6)      ← the point-slope form of the equation

                y = ¹/₃x                   ← the slope-intercept form of the equation

                x - 3y = 0               ← standard form of the equation

Step-by-step explanation:

The slope of line that passes through (-5, 3) and (-1, -9):

\(m_0=\dfrac{3-(-9)}{-5-(-1)}=\dfrac{3+9}{-5+1}=\dfrac{12}{-4}=-3\)

The slope of a line perpendicular to the line with the slope m₀:

\(m=-\dfrac1{m_0}=-\dfrac1{-3}=\dfrac13\)

The point-slope form of the equation of a line: y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.

(6, 2)    ⇒    x₁ = 6,  y₁ = 2

So:

    y - 2 = ¹/₃(x - 6)      ← the point-slope form of the equation

y - 2 = ¹/₃x - 2               {add 2 to both sides}

y = ¹/₃x                   ← the slope-intercept form of the equation

y - ¹/₃x = 0             {multiply both sides by (-3)}

x - 3y = 0               ← standard form of the equation

The average increase in the number of flowers pollinated per day between days 4 and 10 is 39.

What is average increase?

Average increase refers to the average rate of growth that a variable experiences within a given period.

According to the given question:

The number of pollinated flowers as a function of time in days is represented by the function f(x) = \(3^{(x/2)\)

To find the average increase in the number of flowers pollinated per day between days 4 and 10, we use the formula

{f(10) - f(4)}/{10 - 4}

Now f(10) = \(3^{(10/2)\)

               = 243

Also f(4) = \(3^{(4/2)\)

             = 9

Therefore average increase = {f(10) - f(4)}/{10 - 4}

                                               = (243 - 10)/10 - 4

                                               = 234/6

                                               = 39

Thus, the average increase in the number of flowers pollinated per day between days 4 and 10 is 39.

The solution set is {π/8, 3π/8}.

The given equation is cos

2x = 0.

We have to solve this equation for the exact solutions over the interval (0, 2x).

cos 2x = 0

Given equation can be written as:

2 cos^2x – 1 = 0

⇒ cos^2x = 1/2

⇒ cos x = ±(1/2)^(1/2)cos x

= ±(1/√2)

Now, we have to find the values of x in the interval (0, 2x) where

cos x = ±(1/√2)

Let's find the first value of x:cos

x = 1/√2

⇒ x = π/4 (in the interval 0 to 2π)

Similarly, the second value of x:cos x

= -1/√2

⇒ x = 3π/4 (in the interval 0 to 2π)

Therefore, the solution set is {π/8, 3π/8}.

Convert it to a decimal and multiply is the best way to describe rate in simple interest formula.

The real yearly cost of funds over the course of a loan is the annual rate that is charged for borrowing (or made by investing), expressed as a single percentage number. An interest rate indicates how expensive borrowing is or how lucrative saving is. Therefore, if you are a borrower, the interest rate is the sum you pay for borrowing money and is expressed as a percentage of the overall loan amount.

To the nearest hundredth, pi + the square root of forty roughly equals 9.47. The best choice is B.

Rounding a number to a particular value reduces the complexity of the number while increasing readability and accessibility.

When you round to a certain point, the exact digits are maintained on the left side of that point but are rounded or somewhat trimmed from the right.

The limit is set at five.

All right-sided values are made zero if the right-side digit to the digit where we must round off is less than or equal to five; otherwise, it is increased by one and the remaining right-side digits are made zero. If the digit to the right of the decimal point is 5, and there are just zeros or no values after it, we round up (raise by 1 as in 347500 to 34800). (Well there are many detailed rules of rounding)

The following can be used to represent the provided expression, "pi plus the square root of forty to the closest hundredth,"

π + √40

The amount paid for both internet service will be equal after 5 months.

The given values for the two companies include the following;

Company A       $60.00                     $42.95

Company B        $25.00                     $49.95

Let the month in which you will pay the same total amount = x

Since the total amount paid will be equal, the final equation becomes;

60   +  42.95x  = 25   +  49.95x

The value of x is calculated as follows;

\((49.95 - 42.95)x = 60- 25\\\\7x = 35\\\\x = \frac{35}{7} \\\\x = 5\)

The equation is 60 + 42.95x = 25 + 49.95x and the number of months when you would pay the same total amount for each internet service is 5 months

let

x = number of months

Company A

Installment fee = $60.00

price per month = $42.95

Total cost = 60 + 42.95x

To construct the diagram of the set Pn of partitions of n, partially ordered by majorization, we consider the values of n ranging from 1 to 5. Majorization is a mathematical concept that compares the composition of two sets in terms of their sizes and arrangement.

For each value of n from 1 to 5, we start by considering the partitions of n. A partition of n represents a way of splitting n into a sum of positive integers. Majorization, in the context of partitions, compares the sizes and arrangement of the partitions. If one partition can be transformed into another by rearranging the summands, while maintaining the total value, the former partition majorizes the latter.

To construct the diagram, we place the partitions of n as nodes and draw arrows between them to represent the majorization relationships. An arrow from one partition to another indicates that the former majorizes the latter. By examining the partitions of each value of n and determining their majorization relationships, we can create the diagram of the set Pn, partially ordered by majorization.
