Answers

Answer 1

a. Sketch the region of integration in the XY-plane.

b. Reverse the order of integration.

c. Evaluate the integral.

(a) The integral is a double integral, which means that the region of integration is a region in the XY plane. The region of integration is defined by the limits of integration for x and y. However, since the limits of integration are not given, it's not possible to sketch the region of integration in the XY plane.

(b) The integral is already written with the order of integration reversed.

(c) Without the limits of integration, it is not possible to evaluate the integral. The limits of integration are necessary to determine the region of integration, and thus the range of values for x and y over which the integral is to be taken. Without this information, it is not possible to carry out the evaluation of the integral.

Answers

Answer:  1449.9 cm

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

Explanation:

Use the two given angle measures (Y and Z) to find angle X.

X+Y+Z = 180

X+141+25 = 180

X+166 = 180

X = 180-166

X = 14

Angle X is 14 degrees.

-----------

Now use the law of sines to determine side length z.

Make sure your calculator is in degree mode.

z/sin(Z) = x/sin(X)

z/sin(25) = 830/sin(14)

z = sin(25)*830/sin(14)

z = 1449.9438

z = 1449.9 cm is the final answer.

The solution is : the length of z, to the nearest 10th of a centimeter is, 1449.9 cm.

The measure of angle L is 66 degrees, which is found using the sum of the internal angle of a triangle. The length is 3.56 units.

What are internal angles?

A polygon's interior angle is the angle created between its two adjacent sides. Alternately, we may state that the internal angle of a polygon refers to the angle measured at the interior portion of a polygon.

Given that the measure of angle M is 24 degrees and angle K is 90 degrees.

The sum of internal angles of a triangle is 180 degrees, thus:

[tex]\angle M + \angle K + \angle L = 180\\\\24 + 90 + \angle L = 180 \\\\\angle L = 66[/tex]

The length of side LK can be found as follows:

tan 24 = LK / MK

tan 24 = LK / 8

0.44 * 8 = LK

LK = 3.56 units.

The length of LM can be found by applying the Pythagorean theorem.

Step-by-step explanation:

You want the areas of the squares shown in each of the figures.

Pythagorean theorem

The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the other two sides of a right triangle.

a)

The square of the hypotenuse is 17² = 289.

The sum of the squares of the other two sides is ...

  shaded square + (14)² = 17²

  shaded square + 196 = 289

  shaded square = 289 -196 = 93 . . . . cm²

Sabcd = 93 cm².

b)

The square of the diagonal is the sum of the squares of the sides. Each of those squares is the area of interest:

brooke has a square yard with grass and gravel parts as shown. The perimeter of the part covered in gravel is 22 meters. what is the area of the grass section of Brookes yard

Answers

Brooke's yard is a square with a side length of 22 meters.

What is perimeter?

Perimeter is the total distance around the outside edge of a two-dimensional shape. Perimeter is a measure of the length of the boundary of a shape and is typically expressed in units of length, such as feet or meters. Calculating the perimeter of a shape can help you measure the size of a yard, garden, or other outdoor area.

Since the perimeter of the part covered in gravel is 22 meters, we can use the formula for the perimeter of a square (4s) to find the length of one side of the square. Therefore, the side length of the part covered in grass is 4s = 22, or s = 5.5 meters.

Using the formula for the area of a square (A = s²), we can calculate the area of the grass section of Brooke's yard. The area of the grass section of Brooke's yard is A = s²= 5.5²= 30.25 square meters.

Answers

a) To evaluate loga 15, we can use the property of logarithms that states logab = loga + logb. Since 15 = 3 * 5, we can use this property to find that loga 15 = loga 3 + loga 5. Since loga 3 = 0.56 and loga 5 = 0.83, we can add these values to find that loga 15 = 0.56 + 0.83 = 1.39.

The power to which a number must be increased in order to obtain additional values is referred to as a logarithm. The easiest approach to express enormous numbers is this manner.

Numerous significant characteristics of a logarithm demonstrate that addition and subtraction logarithms may also be represented as multiplication and division of logarithms.

b) To evaluate loga(2/5), we can use the property of logarithms that states log(a/b) = loga - logb. Since 2/5 = 2*(1/5) we can use this property to find that loga(2/5) = loga2 - loga(1/5). Since loga2 = 0.36 and loga(1/5) = -loga5, we can subtract these values to find that loga(2/5) = 0.36 - 0.83 = -0.47

c) To evaluate loga (8a^4), we can use the property of logarithms that states log (a^n) = nloga. We get, loga (8a^4)=loga 8 + log (a^4)

A rectangle has a perimeter of 112. If the sides are 5x & 3x + 5, what is x and what are each of the sides?

Answers

The value of X is 7.625 while the two sides are 38.125 and 27.875.

To find the perimeter:

Perimeter = 2(L+B)

112 = 2(5x + 3x + 5)

112 = 2(8x + 5)

Dividing both sides by 2

56 = 8x + 5

56 + 5 = 8x

61 = 8x

x = 61/8

x = 7.625

The sides are;

5x = 5(7.625)

5x = 38.125

This graph has vertices V=1, 2, 3, 5, and edges E=1, 2, 1, 3, 2, 4, and (2.5), (3.5). (4.5). Statistical charts (bar charts, pie charts, line charts, etc.) graphical representations of exponential growth. a logarithmic graph in the shape of a triangle

Here,

Given :

=> h(x) = g(x+3) - 6

g(x) = x+ 25

So,

=> g(x+3) = x +3 + 25 = x+28

and

=> h(x) = x + 28 -6

=>y= h(x) = x+ 22

Thus,

y= x+22

the points which can be graph area:

=> x = 0 , y =22

=> x= 1 , y=23

Therefore , the solution of the given problem of graph comes out to be

x = 0 , y =22 and  x= 1 , y=23.

Which of the following is true of z scores that fall below the mean?
O Group of answer choices
O They are negative.
O They are equal to the mode.
O They are positive.
O They are in the upper half of the distribution.

Answers

The truth of z scores that fall below the mean is - they are negative. Option(b) is the correct answer.

A z-score called a standard score gives an idea of how far from the mean a data point is. But technically it is a calculation of how many standard deviations below or above the population mean a raw score is.

A z-score can place on a normal distribution curve. Z-score ranges from -3 standard deviations up to +3 standard deviations.

A z-score is equal to 0 means that it is on the mean. A positive z-score shows the score is higher than the mean average.

A negative z-score reveals the score is below the mean average.

Graph -3x2+12y2=84 . What Are The Domain And Range?

Answers

The domain and range of the given graph function is R.

The equation -3x^2 + 12y^2 = 84 represents an ellipse in the coordinate plane. The standard form of an ellipse is (x^2/a^2) + (y^2/b^2) = 1, where a and b are the lengths of the semi-major and semi-minor axis, respectively.

To put the given equation in standard form, we need to divide both sides by 84, and divide the x^2 and y^2 by the square of their respective coefficient:

(-3/84)x^2 + (12/84)y^2 = 1

This gives us x^2/ (84/-3)^2 + y^2/ (84/12)^2 = 1

Which gives us x^2/28 + y^2/7 = 1

This means that the semi-major axis has a length of 2sqrt(7) and the semi-minor axis has a length of sqrt(7).

The domain of this function is all real numbers, because the x values can take any real value.

The range of this function is also all real numbers, because the y values can take any real value, within the boundaries of the ellipse.

So, the domain and range of the function -3x^2 + 12y^2 = 84 is all real numbers.

Other Questions
Randy and Sharon are retiring. Their attorney advised each of them to transfer to both of their children (Gerald and Shelia) and each of their 8 grandchildren (Eric, Stanley, Kyle, Kenny, Bebe, Butters, Timmy, and Jimmy) a total of $30,000 per year ($15,000 from Randy and $15,000 from Sharon). This means that each year, Randy and Sharon can "gift" to their family members a total of $300,000. Why would their attorney suggest that Randy and Sharon give away their assets in such a manner? 1) Because the tax bracket that Randy and Sharon's children fall into is smaller than Randy and Sharon's tax bracket; therefore, their children will pay fewer taxes on this income than if they waited until Randy and Sharon were deceased to receive the income. 2) Because their attorney knows that they can each legally gift $15,000 to any one that they choose each year-tax free. 3) Because their attorney is an unscrupulous evil-doer who thinks only of herself. She knows that she will receive a huge commission check from this transfer each year so she advises them to transfer this money each year. 4) Because Randy and Sharon are retired and are in a lower tax bracket than their children so Randy and Sharon will benefit by paying the gift tax based on their tax brackets instead of their children's tax bracket, which is much higher.
