a farmer has 350 feet of fencing and wants to construct 3 pig pens by first building a fence around a rectangular region, then subdividing the region into three smaller rectangles by placing two fences parallel to one side of the rectangle. what dimensions of the region maximizes the total area? what is the maximum area?

We are approximately 17.88 meters from the base of the plateau.

An angle of elevation is the angle formed between a horizontal line and a line of sight that is directed upward to an object or point above the horizontal level. It is commonly used in trigonometry and geometry to determine the height or distance of an object, such as a building, tower, or mountain.

We can use trigonometry to solve this problem. Let's call the distance we are from the base of the plateau "x".

From the problem, we know that the height of the plateau (the opposite side) is 40m and the angle of elevation (the angle between the horizontal and the line of sight to the top of the plateau) is 20 degrees.

Using the tan function, we get,

tan(20) = 40/x

To solve for x, we can cross-multiply:

x * tan(20) = 40

Then, we can divide both sides by tan(20):

x = 40 / tan(20)

Using a calculator, we get:

x ≈ 17.8798 meters

Therefore, we are approximately 17.88 meters from the base of the plateau.

The dimensions of the rectangle are either 25" by 8" or 20" by 10".

The perimeter of a two-dimensional shape is the space surrounding it. It is calculated using length units like inches or metres. The lengths of all the sides of a rectangle are added up to determine its perimeter.

Area is a unit used to describe how much room there is inside a two-dimensional form. It is calculated using area units like square inches or square metres. A rectangle's area is calculated by multiplying its length by its width.

The perimeter of the rectangle is given as:

Perimeter = 2(length + width)

Substituting the value we have:

90 = 2(L + W)

45 = L + W

Now, the area is given as:

Area = length × width

Substituting the values we have:

200 = L × W

The above equation can be written as:

W = 200/L

Substituting the value of W in the first equation we have:

45 = L + 200/L

45L = L² + 200

L² - 45L + 200 = 0

L = (45 ± √(45² - 4×1×200)) / (2×1)

L = (45 ± 5) / 2

L = 25 or L = 20

Now, for L = 25 the value of W is:

W = 200 / 25 = 8

For L = 20:

W = 200 / 20 = 10

Hence, the dimensions of the rectangle are either 25" by 8" or 20" by 10".

Also provided are the amounts for the year's interest expenditure and the balance of interest payable as of December 31, 2013 and 2014.

These are the formulas that can be used to determine the cash paid in interest in 2014:

Interest paid in 2014 minus any increases in interest due equals the cash paid in interest.

The difference between the balance of interest payable as of December 31, 2014, and as of December 31, 2013, can be used to compute the increase in interest payable:

Interest payable at December 31, 2014 minus interest payable at December 31, 2013 equals $6,200 minus $5,700, which equals $500 in

additional interest.

This signifies that the corporation incurred more interest expense than it paid during the year Since the balance of interest payable increased from 2013 to 2014, the corporation incurred more interest expense than it paid in that period. As a result, the money used to pay interest in 2014 is:

Answer:

Step-by-step explanation:

the value of the expression sin A cos B - cos A sin B is √34/5. use the trigonometric identities

what is expression ?

Trigonometric identities are mathematical equations that relate the values of trigonometric functions to one another. They are true for all possible values of the variables involved, and can be used to simplify and solve trigonometric equations.

In the given question,

To solve this problem, we need to use the properties of trigonometric functions to find the values of other trigonometric functions for angles A and B.

We know that:

tan A = opposite/adjacent = 4/3

tan B = opposite/adjacent = 3/5

Using the Pythagorean theorem, we can find the hypotenuse of the right triangles for angles A and B:

For angle A: hypotenuse = √(opposite² + adjacent²) = √(4² + 3²) = 5

For angle B: hypotenuse = √(opposite² + adjacent²) = √(3² + 5²) = √34

Now, we can use the definitions of sine, cosine, and tangent to find their values for angles A and B:

sin A = opposite/hypotenuse = 4/5

cos A = adjacent/hypotenuse = 3/5

sin B = opposite/hypotenuse = 3/√34

cos B = adjacent/hypotenuse = 5/√34

We can simplify these values by rationalizing the denominators:

sin B = 3√34/34

cos B = 5√34/34

Finally, we can use the trigonometric identities to find the value of the expression:

sin A cos B - cos A sin B

Substituting the values we found:

sin A cos B - cos A sin B = (4/5)(5√34/34) - (3/5)(3√34/34)

Simplifying:

sin A cos B - cos A sin B = √34/5

Therefore, the value of the expression sin A cos B - cos A sin B is √34/5.

With 82% confidence that the true average weight gain during the December holidays for the sampled adult population is between -1.25 pounds. and 1.47 pounds.

To find the 82% confidence interval for the mean weight gain over the holidays in December, you can use the following formula:

[tex]CI = xd ± t*(SDd/sqrt(n))[/tex]

where:

xd = average weight change of sample (0.11 lb increase)

SDd = standard deviation of weight difference (5.25 lbs)

n = sample size (23)

t = the critical value of the t distribution with n-1 degrees of freedom and the desired confidence level (82% in this case)

You can use a t-table or a calculator to find the critical value of the t-distribution. With 22 degrees of freedom (n-1) and an 82% confidence level, the critical value is approximately 1.319.

Plugging in the given values ​​gives:

[tex]CI = 0.11 ± (1.319*(5.25/sqrt(23))) = (-1.25, 1.47)[/tex]

Therefore, we can say with 82% confidence that the true average weight gain during the December holidays for the sampled adult population is between -1.25 pounds. and 1.47 pounds.

Note that the confidence intervals include zero. This means that we cannot reject the null hypothesis that there is no significant difference in weight between mid-November and he early-to-mid-January.

If Robert ate lunch at 11:am and he ate a snack 4and a half hours later, Robert ate his snack at 3:30 pm

To find out what time Robert ate his snack, we need to add 4 and a half hours to the time he ate lunch.

Since he ate lunch at 11:00 am, we can convert this time to 24-hour format by adding 12 hours to get 11:00 + 12:00 = 23:00.

Next, we add 4 and a half hours to 23:00 by converting the half hour to minutes and adding it to the minutes portion of the time:

23:00 + 4 hours + 30 minutes = 27:30

However, since there are only 24 hours in a day, we need to convert this time back to 12-hour format. To do this, we subtract 12 hours from 27:30 to get 15:30.

Therefore, Robert ate his snack at 3:30 pm (or 15:30 in 24-hour format).

In summary, we added 4 and a half hours to the time Robert ate lunch, converted the resulting time to 24-hour format, subtracted 12 hours to account for the excess of 24 hours, and then converted the time back to 12-hour format to obtain the time Robert ate his snack.

The height of the cone is approximately 1.5 cm.

Both a cone and a cylinder have circular bottoms and are three-dimensional shapes. The lateral surfaces of the two shapes differ most noticeably from one another. A cone has a lateral surface that tapers from a point at the apex to a circular base, whereas a cylinder has a curved lateral surface that is parallel to its base. The volume of a cylinder is calculated using the formula V = πr²h, where r is the radius of the base and h is the height, whereas the volume of a cone is calculated using V = (1/3)πr²h.

The volume of the cone is given as:

V = (1/3)πr²h

Rearranging the equation to isolate h we get:

3V = πr²h

h = (3V)/(πr²)

Now, for  volume

of 48 cm³ and a base with a radius of 4 cm we have:

The function f(x) = 3x⁵ - 5x³ + 15 has relative maxima at x = -1 and relative minima at x = 1, so the answer is (d) -1 and 1 only.

To find the relative maximum of the function f(x) = 3x⁵ - 5x³ + 15, we need to find the critical points and then determine whether they correspond to a maximum or minimum.

To find the critical points, we need to find where the derivative of the function is equal to zero

f'(x) = 15x⁴ - 15x²

f'(x) = 15x²(x² - 1)

Setting f'(x) equal to zero, we get

x²(x² - 1) = 0

This equation is true when x = 0, x = 1, and x = -1.

Now we need to determine whether these points correspond to a relative maximum or minimum. To do this, we can use the second derivative test.

f''(x) = 60x³ - 30x

Plugging in x = -1, we get

f''(-1) = -30 < 0

This means that x = -1 corresponds to a relative maximum.

Plugging in x = 0, we get

f''(0) = 0

This test is inconclusive, so we need to use another method to determine the nature of the critical point at x = 0.

Plugging in x = 1, we get

f''(1) = 30 > 0

This means that x = 1 corresponds to a relative minimum.

As per the given Equation Each sister received 1 piece of jewelry.

Let's the number of pieces of jewelry that each sister received "x". Since there are 5 sisters, the total number of pieces of jewelry that the sisters received is 5x.

We can then set up an equation to represent the total number of pieces of jewelry that the sisters received from both grandmothers:

13 + y = 5x

This equation says that the total number of pieces of jewelry the sisters received is equal to the sum of 13 pieces from Grandma Gertrude and y pieces from Grandma Fien, and this total is also equal to the number of sisters (5) times the number of pieces each sister received (x).

To solve for x, we can first simplify the equation:

y = 5x - 13

Now we can substitute this expression for "y" into the original equation:

13 + (5x - 13) = 5x

5x = 5x

This equation is true for any value of x, which means that x can be any number. However, we are looking for the number of pieces of jewelry that each sister received, so we need to find a specific value of x.

Dividing both sides of the equation by 5, we get:

x = 1

From the given table, Player A is the most consistent, with an IQR of 1.5. So, correct option is A.

To find the best measure of variability for this data, we need to consider a measure that is robust and resistant to outliers. The interquartile range (IQR) is a good choice as it is calculated based on the range of values that fall within the middle 50% of the data and is therefore less affected by extreme values.

To calculate the IQR, we first need to find the median, which is the middle value in the dataset. For Player A, the median is 3 and for Player B, the median is 2.5.

Next, we calculate the first quartile (Q₁) and the third quartile (Q₃) which represent the 25th and 75th percentiles of the data, respectively. For Player A, Q₁ is 2 and Q₃ is 3.5, while for Player B, Q₁ is 2 and Q₃ is 4.5.

The IQR is the difference between Q₃ and Q₁. For Player A, the IQR is 1.5 (3.5 - 2) and for Player B, the IQR is 2.5 (4.5 - 2). Therefore, Player A is more consistent as their IQR is smaller, indicating that their runs earned are more tightly clustered around the median.

The range, which is the difference between the largest and smallest values in the dataset, is also a measure of variability, but it is sensitive to extreme values. In this case, the range for Player A is 7 (8 - 1) and for Player B is 5 (6 - 1), but these values do not provide as accurate an indication of consistency as the IQR.

To find the median, the data needs to be arranged in order from least to greatest: 19, 48, 140, 220.

Since there is an even number of data points, the median is the average of the two middle values, which in this case are 48 and 140. Adding them together and dividing by 2 gives 94, which is less than the next highest value of 220.

Therefore, the median length of time required to review an application is 105 minutes.
