Answer:

Step-by-step explanation:

Formula

Area = 1/2 (b1 + b2)*h

Givens

b1 = 5

b2 = 11.5

h = 4.5

Solution

Area = 1/2 (5 + 11.5)* 4.5

Area = 1/2 (16.5)*4.5

Area = 1/2 (74.25)

Area = 37.125

Answer:

$283.2

Step-by-step explanation:

Area of the order = Length * Width

7.02×10^3 = 1.17×10^2 * Width

7020 = 117W

W = 7020/117

W = 60feet

Perimeter of the border = 2(L+W

P = 2(117+60)

P = 2 * 177

P = 354 feet

If a border cost $0.80 per foot, 354 feet long border will cost 0.80 * 354 = $283.2

Answer:

It's actually $283.20. I found out by putting the answer the other person put so I got it wrong the correct answer is $283.20 I hope this helps :)

Answer:

So the value is 18 dollars off which is $42

Step-by-step explanation:

Well we know 50% of 60 is 30 so we want to multiply 60 x 30 = 180 and the denominator would be 100 so 180/100 now we make 180, 18! which makes 18 dollars off so 60 - 18 = 42

The forecast sales value for year 32 is approximately 526.94. The linear regression trend line equation is of the form: \(y = mx + b.\)

Where m is the slope of the line, b is the y-intercept, and x is the independent variable. In this case, the equation is given as Fi-18.221. Here, i represents the year. Therefore, we can write the equation as: Fi = -18.221i + C, where C is a constant. To find the value of C, we need to use the given data for the last 30 years. Let's assume the year 1 is the starting year.

Then we have the following data: Year (i) Sales (Fi)1 202 2153 2234 2315 2486 2557 2638 2709 28610 29411 31212 31913 32414 33015 34516 35617 36718 37919 39420 40621 41222 42723 43924 44825 45526 46727 48028 49929 50830 517We know that the regression equation represents the line that best fits the given data.

Answer:

x = 3

Step-by-step explanation:

First you want to divide both sides by 5 to get 2x-4 = 2.

Afterwards, you add 4 to both sides of the equation. 2x = 6

Divide both sides by 2. x = 3

The value of x = 3 is correct. Therefore, the solution is x = 3.

To solve for x in the equation 5(2x - 4) = 10, follow these steps:

Step 1: Distribute the 5 on the left side of the equation:

10x - 20 = 10

Step 2: Add 20 to both sides to isolate the term with x:

10x - 20 + 20 = 10 + 20

10x = 30

Step 3: Divide both sides by 10 to find the value of x:

x = 30 / 10

x = 3

The solution to the equation is x = 3. To verify, substitute x with 3 in the original equation:

5(2(3) - 4) = 10

5(6 - 4) = 10

5(2) = 10

10 = 10

Since both sides are equal, the value of x = 3 is correct. Therefore, the solution is x = 3.

The answer is, the maximum of f(x,y) on the boundary of R is √8 and the minimum is -√8. So, the absolute maximum and minimum values of the given function on the specified region R = {(x,y): -3 ≤ x ≤ 3, 0 ≤ y ≤ √9 - x²} are as follows;Absolute maximum value of f(x,y) = √8 when (x, y) = (1, √8)Absolute minimum value of f(x,y) = -√8 when (x, y) = (-1, √8)."

The given function is f(x,y)

= xy on the semicircular disk and the specified region R isR

= {(x,y): -3 ≤ x ≤ 3, 0 ≤ y ≤ √9 - x²}Firstly, we need to check for the critical points by taking partial derivatives of f(x,y) as follows;fx(x, y)

= yfy(x, y)

= xSo the critical points will be at(x, y)

= (0, 0)Now we need to check the boundary of the region R. The boundary of R consists of three curves, namely;x

= -3x = 3y

= 0y

= √9 - x²Now we will check for absolute minimum and maximum on the boundary of R.i) When x

= -3, the function becomes f(-3, y)

= -3y, where 0 ≤ y ≤ √9 - (-3)²

= √9 - 9

= 0Therefore, the function value on the boundary y

= 0 is f(-3, 0)

= 0ii) When x

= 3, the function becomes f(3, y)

= 3y, where 0 ≤ y ≤ √9 - 3²

= 0Therefore, the function value on the boundary y

= 0 is f(3, 0)

= 0iii) When y

= 0, the function becomes f(x, 0)

= 0, where -3 ≤ x ≤ 3Therefore, the function value on the boundary x

= -3 is f(-3, 0)

= 0 and f(3, 0)

= 0iv) We need to maximize the function over the semicircle, that is, y

= √9 - x², where -3 ≤ x ≤ 3.The function becomes f(x, √9 - x²)

= x(√9 - x²)

= √9x - x³.For the critical points (0, 0), we have f(0, 0) = 0.For maximum and minimum, we have to take the first derivative of f(x,√9 - x²).f'(x

) = 3 - 3x²

= 0Or, x

= ±1 Therefore, the critical points on the semicircle are (1, √8) and (-1, √8).Putting x

= 1 and x

= -1, we have y

= √8.Thus the function values on the semicircular boundary are f(1, √8)

= √8, f(-1, √8)

= -√8.The maximum of f(x,y) on the boundary of R is √8 and the minimum is -√8. So, the absolute maximum and minimum values of the given function on the specified region R

The absolute maximum and minimum values of the function f(x, y) = xy on the specified region R are both 0.

Region R: {(x, y): -3 ≤ x ≤ 3, 0 ≤ y ≤ √(9 - x²)}

1. Critical Points:

To find critical points, we need to take the partial derivatives of f(x, y) with respect to x and y and set them equal to zero.

∂f/∂x = y = 0

∂f/∂y = x = 0

From the first equation, y = 0, and from the second equation, x = 0. So, the critical point is (0, 0).

2. Boundary Points:

We need to evaluate the function at the boundary of the region R.

2.1. When y = 0:

f(x, 0) = x * 0 = 0

The boundary point (x, 0) will always give f(x, 0) = 0.

2.2. When y = √(9 - x²):

f(x, √(9 - x²)) = x * √(9 - x²)

Now, we need to evaluate the function at the endpoints of the x-interval [-3, 3] and find the maximum and minimum values.

For x = -3:

f(-3, √(9 - (-3)²)) = f(-3, 0) = 0

For x = 3:

f(3, √(9 - 3²)) = f(3, 0) = 0

The length of the rectangle is 19 cm.

The formula for the area of a rectangle,

Area = Length x Width

Given that the area is 336 cm squared.

So, we can set up an equation,

⇒ 336 = (w + 5)w

where w represents the width of the rectangle.

Expanding this equation,

⇒ 336 = w² + 5w

Moving all terms to one side:

⇒ w² + 5w - 336 = 0

This is a quadratic equation that we can solve using the quadratic formula,

⇒ w = (-5 ± √(5² - 4(1)(-336))) / (2(1))

⇒ w = (-5 ± 23) / 2

We'll take the positive value,

⇒ w = 14

So, the width of the rectangle is 14 cm.

We also know that the length is 5 cm more than the width,

Therefore,

⇒ l = w + 5

⇒ l = 14 + 5

⇒ l = 19

Therefore, the length of the rectangle is 19 cm.

Step-by-step explanation:

We can find the distance between line l and point P by finding the distance between point P and the closest point on line l.The slope of line l is 0, since both points have the same y-coordinate. Therefore, line l is a horizontal line. The y-coordinate of any point on line l is 1.To find the closest point on line l to point P, we need to find the point on line l that has a y-coordinate of 7. Since line l is horizontal, any point on line l with a y-coordinate of 7 will work. Let's choose the point (5, 7), which is on the same horizontal line as line l.Now we can find the distance between point P and the point (5, 7):sqrt((5-(-2))^2 + (7-1)^2) = sqrt(49 + 36) = sqrt(85)Therefore, the distance between line l and point P is sqrt(85).

Answer:

Step-by-step explanation:

The function f(t) is equal to the antiderivative of f'(t) = 2 cos(t) + sec²(t), -1/2.

To find the antiderivative, we need to integrate 2 cos(t) + sec²(t) with respect to t.  Using the trigonometric identity, sec²(t) = 1/cos²(t), we can rewrite the integral as: ∫[2cos(t) + sec²(t)]dt = ∫[2cos(t) + 1/cos²(t)]dt

Now, using the power rule of integration, we can integrate each term separately:

∫2cos(t) dt = 2sin(t) + C1

∫1/cos²(t) dt = ∫sec²(t) dt = tan(t) + C2

where C1 and C2 are constants of integration.

Therefore, the antiderivative of f'(t) is given by:

f(t) = 2sin(t) + tan(t) - 1/2

Note that the constant of integration is represented by -1/2 instead of C, since the original problem specifies the initial condition f'(t) = 2 cos(t) + sec²(t), -1/2.

The sum of the number in the binary form is 1001010 and the values of m is 0 and n is 1.

Binary Number System: A binary number is a number that is stated in the binary system or base 2 numeral system, according to mathematics. It uses the symbols 1 (one) and 0 to represent different numeric values (zero). The notation with 2 as a radix is known as the base-2 system.

The binary number can be expressed in decimals as follows:

\(11111_2 = 1*2^4 + 1*2^3+1*2^2+ 1*2^1+1*2^0\\\\11111_2= 31\\\\10000_2= 1*2^4\\\\10000_2 = 16\)

The sum of all the numbers is:

27 + 31 + 16 = 74

To convert the decimal in the binary form, divide the number continuously and note the remainder until it cannot be divided any further.

74 ÷ 2= 37= 0

37 ÷ 2 = 18 = 1

18 ÷ 2 = 9 = 0

9 ÷ 2 = 4 = 1

4 ÷ 2 = 2 = 0

2 ÷ 2 = 1 = 0

A positively skewed distribution is due to an extremely large number.

A positively skewed distribution is a type of distribution in which the majority of the data values are clustered towards the left side of the distribution, with a tail extending to the right. This means that there are relatively more smaller values in the dataset than larger values. In a positively skewed distribution, the mean of the dataset is typically larger than the median, and the mode may not be a good representation of the central tendency of the data. This is because the presence of a long tail on the right-hand side of the distribution pulls the mean towards the higher values, while the median remains closer to the center of the dataset. Some common examples of positively skewed distributions include income distributions, where there are a few extremely high earners that skew the data towards the right, and test scores, where there may be a few students who perform extremely well and pull the average higher than the median.

Here,

A positively skewed distribution occurs when the tail of the distribution extends to the right, and the majority of the data is clustered towards the left side of the graph. This means that there are relatively more smaller values in the dataset than larger values. One common cause of positive skewness is the presence of extremely large values, also called outliers, in the dataset. These large values pull the mean of the dataset towards the right, resulting in the tail of the distribution stretching in that direction.
