The area of the sheet of paper in correct metric units is 602.6c\(m^{2}\).

A region's size on a plane or curved surface is expressed by the term "area," which is a mathematical concept. As opposed to surface area, which refers to the area of an open surface or the boundary of a three-dimensional object, plane region or plane area refers to the area of a form or planar lamina. Area can be thought of as the volume of material, at a particular thickness, required to create a model of the shape, or as the volume of paint required to paint the surface in a single coat. It is equivalent to the volume of a solid or the length of a curve in two dimensions (a three-dimensional concept).

Calculations:

The length of a 8 X 11 paper in metric unit is 27.9 cm and width of 8 X 11 paper in metric unit is 21.6 cm.

Area of sheet of paper=length*width

               =27.9*21.6

               =602.6 c\(m^{2}\)

Answer:

1) AC = 6 cm

2) AB = 16.2 cm      ( note that ^{2} is = square and \sqrt{  this is = square root)

3) BC = 12.65cm

Step-by-step explanation:

1) a^{2} + b^{2} = c^{2}

4.8^{2} + 3.6^{2} = AC^{2}

36 = AC^{2}

\sqrt{ }36 = AC

AC = 6

2)   a^{2} + b^{2} = c^{2}

AB^{2} + 6.75^{2} = 17.55^{2}

AB^{2} = 308.0025 - 25.5625

AB = \sqrt{ }262.44

AB = 16.2

3)  a^{2} + b^{2} = c^{2}

BC^{2} + 6^{2} = 14^{2}

BC^{2} = 196 - 36

BC = \sqrt{ } 160

BC = 12.65

The 8 painters will take 12 hours and 9.6 minutes to paint the office. The result is obtained by comparing the two variables, worker and time duration.

If the they work at the same rate, find the time needed for the 8 painters to finish their job!

Let's say

We convert the unit of time in hours.

t₁ = 7 h 36 min

t₁ = (7 + 36/60) h

t₁ = (7 + 0.6) h

t₁ = 7.6 hours

If they work at the same rate, the number of workers and time durations of each day are directly proportional. So,

w₁/w₂ = t₁/t₂

5/8 = 7.6/t₂

t₂ = 8/5 × 7.6

t₂ = 12.16 hours

In hours and minutes,

t₂ = 12 h + (0.16 × 60) min

t₂ = 12 h 9.6 min

Hence, to paint the office, the 8 painters will take 12 hours and 9.6 minutes.

To find the volume of the solid obtained by rotating the region bounded by the curves y = x³, x = 0, and x = 1 rotated around the y = −2, we can use the method of cylindrical shells.

The method of cylindrical shells involves integrating the volume of thin cylindrical shells that make up the solid. Here are the steps to follow:

Step 1: Draw a rough sketch of the region and the axis of rotation. The region is bounded by y = x³, x = 0, and x = 1, and is rotated around the line y = −2.

Step 2: For a given value of y, find the corresponding x-values of the curves that bound the region. In this case, the bounds are x = 0 and x = y¹/³

Step 3: The radius of the cylindrical shell is the distance between the axis of rotation and the curve. In this case, the radius is y + 2.

Step 4: The height of the cylindrical shell is the difference between the x-values of the curves at a given y-value. In this case, the height is x = y¹/³

Step 5: The volume of the cylindrical shell is given by the formula: V = 2πrh, where r is the radius and h is the height.

Step 6: Integrate the volume of the cylindrical shells over the range of y-values that span the region, which is from y = 0 to y = 1. The integral to evaluate is:

V = ∫(y=0 to y=1) 2π(y + 2)(y¹/³)) dy

Step 7: Simplify and evaluate the integral using standard techniques of integration, such as u-substitution. The result will be the volume of the solid.

After integrating and simplifying the integral, we get:

V = (32/5)π

Therefore, the volume of the solid obtained by rotating the region bounded by the curves y = x^3, x = 0, and x = 1 around the y = −2 is (32/5)π cubic units.

Answer:

Love The Way You Lie - Eminem

Answer:

B: \(y=-\frac{1}{3}x+7\)

Step-by-step explanation:

Straight lines are set out in the format of \(y = mx+c\), where \(m\) is the gradient, and \(c\) is the y-intercept.

The gradient between parallel lines remains the same, and this means the gradient of the new line will also be \(-\frac{1}{3}\).

This rules out options C and D.

Going back to the format, so far, we have filled in \(y=-\frac{1}{3}x+c\). We are still looking for the y-intercept.

We can find that using the coordinate you've been given, \((6,5)\).

This coordinate tells us that when \(x=6\), \(y=5\). Therefore we can substitute those in the places of \(x\) and \(y\) in the original equation.

This leaves us with \(5 = -\frac{1}{3}(6)+c\).

We can now rearrange for \(c\).

\(5 = -2 + c\\c=7\)

Now we have all the values we need, we can form the final equation.

\(y=-\frac{1}{3}x+7\)

This indicates the answer is option B. Hope this helps.

(a) The cost of one notebook is $2.75 and one pen is $1.10.

(b) He can purchase 3 notebook, if he has $22.

In the given question, the cost of 3 notebooks and 2 pens is $10.45. The cost of 4 notebooks and 6 pens is $17.60.

(a) We have to find the cost of each item.

Let the mean price of notebook = x

Let the mean price of pen = y

3x + 2y = 10.45 ………(i)

4x + 6y = 17.60 ………(ii)

Multiply Equations (i) by 3

9x + 6y = 31.35...............(iii)

Subtract equation (iii) and (ii)

5x = 13.75

x= 2.75

Substitute x value in equation (i) to get the value of y

3(2.75) + 2y = 10.45

2y = 2.20

y = 1.10

b) We have to find how many notebooks he can purchase if he has $22.

Miles needs to purchase some new school supplies.

For each notebook he buys he will buy 3 pens.

Let us consider, m to be mean number of notebooks.

2.75m + 1.10 (3m) = 22

For example, if he buys 2 notebooks, he buys 3m = 6 pens.

2.75m + 3.30m = 22

6.05m = 22

m = 3.64

He must buy an integer number of notebooks that is less than or equal to 3.

Answer:

A

Step-by-step explanation:

Answer:

AD = 10

Step-by-step explanation:

It's given that ABCE is a rectangle.

Therefore, measure of opposite sides of the rectangle will be equal.

AB = EC

AB = ED + DC

12 = ED + 4

ED = 8

Measure of side AE = 6

Since, measure of interior angles of a rectangle = 90°

Therefore, ΔEAD will be a right triangle.

By Pythagoras theorem,

AD² = AE² + ED²

      = 6² + 8²

AD = \(\sqrt{36+64}\)

      = \(\sqrt{100}\)

      = 10

Therefore, measure of side AD = 10 units

The composite Simpson’s rule approximates the integral by applying Simpson’s rule to each of these m sub-intervals and adding up the results. So, T1,m corresponds to the composite Simpson's rule.

Given: T1, m defined in (6.32). To,

(f) = N-1 N-1 h 1 { f(x) + f(xXx) + 2 Σ¹ f(x) + 4*Σ* ƒ((x₂ + x + 1)/2) 6 j

=1 j

=0

To show: T1, m corresponds to the composite Simpson's rule

Formula for Simpson's rule for n=2, f(x) is a function on [a, b], and h = (b − a)/2:S2(f) = h/3 [f(a) + 4f((a + b)/2) + f(b)]

Here, the interval [a,b] is partitioned into two intervals of equal length and the composite Simpson’s rule approximates the integral by applying Simpson’s rule to each of the sub-intervals and adding up the results.So,T1,m can be rewritten as (6.32):

T1,m = h/3 [ f(x0) + 4f(x1/2) + 2f(x1) + 4f(3/2) + ... + 2f(xm-1) + 4f(xm-1/2) + f(xm)]                

 = (h/3) [f(x0) + 4f(x1/2) + 2f(x1) + 4f(3/2) + ... + 2f(xm-1) + 4f(xm-1/2) + f(xm)]

Here, we can see that m sub-intervals of the form [xi-1, xi] are formed by the partition of the interval [a,b] into m sub-intervals. Each sub-interval has a length of h = (b − a)/m = x1 − x0. The composite Simpson’s rule approximates the integral by applying Simpson’s rule to each of these m sub-intervals and adding up the results. So, T1,m corresponds to the composite Simpson's rule.

Step-by-step explanation:

You want to know the price per bushel for wheat, corn, and rye, given the sales ...

Using x, y, and z for price per bushel of wheat, corn, and rye, respectively, the given sales tell us ...

The easiest way to solve a system of equations like this is to make use of the matrix manipulation capabilities of a calculator. The attached calculator display shows the reduction of the augmented matrix of coefficients to "reduced row-echelon form". That puts the solution in the last column:

  x = y = 3.61, z = 1.91

The price per bushel for wheat and corn is the same: $3.61; the price per bushel for rye is $1.91.

Additional comment

The second attachment shows a solution using a graphing calculator. In this solution, an expression for z based on the first equation is used in the remaining two equations, which then tell us the values of x and y.

If you add all of the equations, you get 10x +10y +10z = 91.30, which gives you ...

  x + y + z = 9.13

This can be solved for any variable you may want to substitute into any pair of the equations. This approach avoids any messy fractions.

When the value of the outputs cannot be determined even if the value of the controllable input is known, the model is said to be non-deterministic or stochastic.

It means that the output of the model can vary randomly based on some probability distribution, and cannot be predicted with certainty. Non-deterministic models are commonly used in areas such as finance, economics, and weather forecasting, where the inputs are subject to uncertainty and the outcomes are probabilistic in nature.

In contrast, deterministic models always produce the same output for a given set of inputs, and are used in areas such as physics and engineering, where the outcomes are expected to be precise and repeatable.

You want to know how to determine the y-intercepts of a rational function, and their possible number.

A rational function f(x) is the ratio of two polynomial functions p(x) and q(x):

  f(x) = p(x)/q(x)

As such, both numerator and denominator have single function values for any value of the independent variable. The y-intercept of f(x) is ...

  f(0) = p(0)/q(0)

The values of p(0) and q(0) are simply the constant terms in those respective functions.

The simple way to find the y-intercept is to look at the ratio of the constant terms in the polynomial functions making up the rational function. If that is defined, there is one y-intercept. If it is undefined (q(0)=0), then there are no y-intercepts.
