======================================================

Explanation:

Let's divide the figure into 3 regions.

The goal is to find A+B+C

---------------

Region A:

A full circle has area of pi*r^2. Plug in the radius of 3 (half the diameter 6) and we get 9pi as the exact area. Your teacher wants you to replace pi with 3, so 9pi = 9*3 = 27 approximately

27 represents the approximate area of the full circle, but we want only half of it. So 27/2 = 13.5 is the approximate area of region A.

--------------

Region B

area = length*width

area = 10*6

area = 60 square inches

---------------

Region C

The base of the triangle is 14-10 = 4 inches. The height is the same as the rectangle (6 inches).

area = 0.5*base*height

area = 0.5*4*6

area = 12 square inches

-------------

  work = 1,830,000 ft·lb

Step-by-step explanation:

You want the work done to lift 650 lb of coal 600 ft up a mine shaft using a cable that weighs 8 lb/ft.

For some distance x from the bottom of the mine, the weight of the cable is ...

  8(600 -x) . . . . pounds

The total weight being lifted is ...

  f(x) = 650 +8(600 -x) = 5450 -8x

The incremental work done to lift the weight ∆x feet is ...

  ∆w = force × ∆x

  ∆w = (5450 -8x)∆x

We can use a sum for different values of x to approximate the work. For example, the work to lift the weight the first 50 ft can be approximated by ...

  ∆w ≈ (5450 -8·0 lb)(50 ft) = 272,500 ft·lb

If we use the force at the end of that 50 ft interval instead, the work is approximately ...

  ∆w ≈ (5450 -8·50 lb)(50 ft) = 252,500 ft·lb

We can see that the first estimate is higher than the actual amount of work, because the force used is the maximum force over the interval. The second is lower than the actual because we used the minimum of the force over the interval. We expect the actual work to be close to the average of these values.

The attached spreadsheet shows the sums of forces in each of the 50 ft intervals. The "left sum" is the sum of forces at the beginning of each interval. The "right sum" is the sum of forces at the end of each interval. The "estimate" is the average of these sums, multiplied by the interval width of 50 ft.

The required work is approximated by 1,830,000 ft·lb.

__

Additional comment

The actual work done is the integral of the force function over the distance. Since the force function is linear, the approximation of the area under the force curve using trapezoids (as we have done) gives the exact integral. It is the same as using the midpoint value of the force in each interval.

Because the curve is linear, the area can be approximated by the average force over the whole distance, multiplied by the whole distance:

  (5450 +650)/2 × 600 = 1,830,000 . . . . ft·lb

Another way to look at this is from consideration of the separate masses. The work to raise the coal is 650·600 = 390,000 ft·lb. The work to raise the cable is 4800·300 = 1,440,000 ft·lb. Then the total work is ...

  390,000 +1,440,000 = 1,830,000 . . . ft·lb

(The work raising the cable is the work required to raise its center of mass.)

W = 24/6 = 4

The formula for the perimeter of a rectangle is P=2L + 2W.

If the width is W = 4 and the length is L=6, then the perimeter becomes:

P = 2(6) + 2(4)

The solution to the inequality "four-thirds times the absolute value of the quantity one fourth times x plus 3 end quantity is less than 4" is: C. x > −24 and x < 0.

In order to determine the solution to the given inequality, we would first of all translate the word description into an absolute value function (inequality) as shown below.

The word description "Four-thirds times the absolute value of the quantity one fourth times x plus 3 end quantity is less than 4" is given by:

Expression = 4/3 × |x/4 + 3| < 4

Expression = 4/3|x/4 + 3| < 4

By solving the expression within absolute value symbol, we have:

x/4 + 3 = (x + 12)/4

4/3|(x + 12)/4| < 4

Multiplying both sides of the inequality by 3/4, we have the following:

4|(x + 12)/4| < 12

(x + 12)/4 < 3

x + 12 < ±12

x > -12 - 12

Answer:

\(90 {cm}^{2} \)

Step-by-step explanation:

First we have to split the entire shape into smaller pieces. We see two triangles and 3 rectangles.

\(area \: of \: tringle = \frac{1}{2} base \times height\)

The base of the triangle is 3 and the height is 4

\( \frac{1}{2} (3) \times 4 = 6 \)

we then multiply 6 by 2 because there are two triangles and both of them are equal (have the same measurement): 《6 x 2 = 12 cm^2》

\(area \: \: of \: rectangle = length \times width\)

Therefore the area of the rectangle on the side would be: 《6 x 5 = 30》. It would also be multiplied by two because there are two rectangles at the side (both being equal) :《30 x 2 = 60 cm^2》

There is also a rectangle at the base of the shape, we use the same formula to find its area: 《6 x 3 = 18 cm^2》

We now add all of the areas that we got for the shapes: 12 + 60 + 18 = 90

To find the flux of the vector field F = (0, 0, 3) across the slanted face of the tetrahedron, we need to calculate the surface integral over the region R in the xy-plane.

The equation of the slanted face of the tetrahedron is given by z = 5 - x - y. To determine the limits of integration for the double integral, we need to find the projection of the region R onto the xy-plane.

By setting z = 0 in the equation of the slanted face, we can solve for the corresponding values of x and y:

0 = 5 - x - y

x + y = 5

This equation represents a straight line in the xy-plane passing through the points (5, 0) and (0, 5). This line determines the bounds for the double integral.

The flux integral can be set up as follows:

Flux = ∬_R F · n dA

Here, F = (0, 0, 3) is the vector field, and n is the outward unit normal vector to the surface. Since the normal vectors point upward, we can take n = (0, 0, 1).

The double integral over the region R in the xy-plane becomes:

Flux = ∬_R (F · n) dA

    = ∬_R (0, 0, 3) · (0, 0, 1) dA

    = ∬_R 3 dA

Since the integrand is a constant, we can evaluate the double integral by finding the area of region R in the xy-plane and multiplying it by the constant:

Flux = 3 * Area(R)

To determine the area of region R, we can calculate the area of the triangle formed by the line x + y = 5. The vertices of this triangle are (0, 5), (5, 0), and the origin (0, 0).

Using the formula for the area of a triangle, we have:

Area(R) = (1/2) * base * height

        = (1/2) * 5 * 5

        = 12.5

Therefore, the flux of the vector field across the slanted face of the tetrahedron is given by:

Flux = 3 * Area(R)

    = 3 * 12.5

    = 37.5

f′(x) = 4x^3 + 2, ∫x^4+2x/(2x^3+1) dx = 19.9 (approx.)

The first part of the question requires finding the derivative of f(x), which is f′(x) = 4x^3 + 2.

To evaluate the integral in the second part, we use the substitution u = 2x + 1. The integral becomes ∫(u^2)/(u + 1) du. Simplifying this expression leads to the result ∫(u^2 - u + 1 - 1)/(u + 1) du = ∫(u^2 - u + 1)/(u + 1) du = ∫(u - 1 + 2/(u + 1)) du.

Using this result, we can compute the definite integral ∫[0,4] (x^2)/(x + 1) dx by substituting u = 2x + 1 and evaluating the integral in terms of u. The result is approximately 19.9, correct to three significant figures.

This method works because it uses the right triangle theorem.

Triangle is a three-sided polygon that has three vertices and three angles. It is one of the basic shapes in geometry. A triangle with all sides equal is called an equilateral triangle, one with two sides equal is called an isosceles triangle, and one with all sides of different lengths is called a scalene triangle. Triangles are used in many fields, including engineering, architecture, and art.

The right angle of the triangle is formed by the line of sight from your eye to the balloon, and the two sides of the triangle are formed by the ground to your eye measurement and the distance from you to the gym wall. By multiplying the two measurements, you can estimate the height of the balloon from the ground.

This measuring method is simple and easy to use. All that is needed is a cardboard square, a tape measure, and a friend to help. It is also accurate since it uses the right triangle theorem. However, it is only an estimate of the true distance from the ground to the balloon.
