circumference of the circle(c)=?

We know that;

[tex]C=2{\pi}r[/tex]

[tex] \: \: \: \: = 2 \times 3.14 \times 9[/tex]

[tex]\: \: \: \: = 56.52[/tex]

Thus,the circumference of the circle is 56.52 cm.

The value of the angles A, B and C are calculated as:

A = 61°

B = 62°

C = 47°

The sum of angles on a straight line is 180 degrees.

Thus:

B + 61 + 47 = 180

B = 180 - (61 + 47)

B = 62°

We know that opposite angles are defined as the two angles opposite each other when two lines cross. They can also be called vertical angles due to sharing a vertex, which is the point where the two lines connect.

Thus:

C = 47°

To prove the equation csc^4(x) - cot^4(x) = csc^2(x) + cot^2(x), we can start by expressing the trigonometric functions csc(x) and cot(x) in terms of sine and cosine:

csc(x) = 1/sin(x)

cot(x) = cos(x)/sin(x)

Substituting these expressions into the equation, we get:

(1/sin(x))^4 - (cos(x)/sin(x))^4 = (1/sin(x))^2 + (cos(x)/sin(x))^2

Next, we simplify each term separately:

(1/sin(x))^4 = 1/sin^4(x)

(cos(x)/sin(x))^4 = cos^4(x)/sin^4(x)

Expanding the powers, we have:

1/sin^4(x) - cos^4(x)/sin^4(x) = 1/sin^2(x) + cos^2(x)/sin^2(x)

Combining the fractions on the left side:

(1 - cos^4(x))/sin^4(x) = (1 + cos^2(x))/sin^2(x)

Now, let's simplify the left side:

1 - cos^4(x) = sin^4(x)

Using the identity sin^2(x) + cos^2(x) = 1, we can rewrite the equation as:

sin^4(x) = sin^4(x)

The equation simplifies to an identity, showing that the original equation csc^4(x) - cot^4(x) = csc^2(x) + cot^2(x) is true for all values of x.

The number of bales purchased for the farm is n = 7 bales

Given data ,

Dan works on a horse farm. There are 10 horses on the farm and they each eat 140 pounds of hay in a week

Now , Dan buys new hay for the farm every week

To find the total amount of hay needed for the week, we multiply the amount consumed by each horse by the number of horses:

Total hay needed = 10 horses x 140 pounds/horse = 1400 pounds

To determine the number of bales needed, we divide the total hay needed by the weight of each bale:

Number of bales needed = Total hay needed / Weight of each bale

On simplifying the equation , we get

Number of bales needed for agri supply = 1400 / 75 = 18.667

Number of bales needed for farm supply = 1400 / 150 = 9.33

Number of bales needed for tractor supply = 1400 / 200 = 7 bales

Number of bales needed ≈ 7 bales when there is not leftover

The three costs that contribute to the total cost of a mortgage are the down payment, mortgage tax and monthly interest.

The correct option is a.

We have,

A down payment can be understood as a sum of money that a buyer pays in the early stages of purchasing an expensive good or service. The down payment represents a portion of the total purchase price, and the buyer will often take out a loan to finance the remainder. A down payment is a money paid upfront in a financial transaction, such as the purchase of a home or car.

Buyers often take out loans to finance the remainder of the purchase price. The higher the down payment, the less the buyer will need to borrow to complete the transaction, the lower their monthly payments, and the less they'll pay in interest over the long term.

Depending on the borrower and the type of purchase, lenders may require down payments as low as 0% or as high as 50%.

The sum of magnitude of vectors is 17.4 and direction is 88 degree.

Hence, option 3 is correct.

Given that,

Vector A: magnitude = 12 and direction = 60 degree

Vector B: magnitude = 10 and direction = 150 degree

Find the x and y components using the following formulas,

Ax = AcosΘ and Ay = AsinΘ

Substitute the values,

Ax = 12cos(60) and Ax = 6

Ay = 12sin(60) and Ay = 10.39

For vector B,

By using the same formulas,

Bx = 10cos(150) and  Bx = -5

By = 10sin(150)  and By = 7.66

We have the x and y components of both vectors,

Add them,

Rx = Ax + Bx

⇒ Rx = 6 + (-5)

⇒ Rx = 1

⇒ Ry = Ay + By

⇒ Ry = 10.39 + 7.66

⇒ Ry = 18.05

Finally, we can find the magnitude and direction of the resulting vector,

Magnitude = √(R²x + R²y)

Therefore, after putting values we get,

Magnitude = 17.4

Direction = [tex]tan^{-1}[/tex](Ry/Rx)

                = [tex]tan^{-1}[/tex](18.05/1)

Step-by-step explanation:

You want the volume of a right triangular prism with a base right triangle that has a leg length of 3 cm and a hypotenuse of 5 cm. The height of the prism is 11 cm.

The base triangle is a 3-4-5 right triangle, so will have an area of ...

  A = (1/2)bh

  A = (1/2)(4 cm)(3 cm) = 6 cm²

The volume of the prism is ...

  V = Bh . . . . . where B is the base area

  V = (6 cm²)(11 cm) = 66 cm³

The volume of the prism is 66 cubic centimeters.

Additional comment

As you can see, the "work" is greatly simplified by the recognition of the {3, 4, 5} right triangle. If you must use the Pythagorean theorem to find the missing side length, you will find it to be ...

  b = √(c² -a²) = √(5² -3²) = √16 = 4

The answer can be estimated by realizing the missing dimension is less than 5. The volume of a rectangular prism of side lengths 3, 5, and 11 would be 3·5·11 = 165 cm³. A triangular prism with the same overall dimensions would have 1/2 that volume, or 82.5 cm³. Since the prism shown has a side length less than 5, its volume will be smaller than 82.5 cm³.

a. To find the probability that family expenses for the weekend will be less than $400, we need to standardize the value using the formula z = (x - μ) / σ, where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation. In this case, x = $400, μ = $749, and σ = $225. So, z = (400 - 749) / 225 = -1.56. Using a standard normal distribution table or calculator, we can find that the probability of a standard normal variable being less than -1.56 is approximately 0.0594. Therefore, the probability that family expenses for the weekend will be less than $400 is about 0.0594 or 5.94%.

b. To find the probability that family expenses for the weekend will be $800 or more, we again need to standardize the value. In this case, x = $800, μ = $749, and σ = $225. So, z = (800 - 749) / 225 = 0.227. Using a standard normal distribution table or calculator, we can find that the probability of a standard normal variable being greater than 0.227 is approximately 0.409. Therefore, the probability that family expenses for the weekend will be $800 or more is about 0.409 or 40.9%.

c. To find the probability that family expenses for the weekend will be between $500 and $1000, we need to standardize both values and then find the area between them. For $500, z = (500 - 749) / 225 = -1.11, and for $1000, z = (1000 - 749) / 225 = 1.11. Using a standard normal distribution table or calculator, we can find that the probability of a standard normal variable being less than -1.11 is approximately 0.1335 and the probability of a standard normal variable being less than 1.11 is approximately 0.8664. Therefore, the probability that family expenses for the weekend will be between $500 and $1000 is about 0.8664 - 0.1335 = 0.7329 or 73.29%.

d. To find the Labor Day weekend expenses for 5% of the families with the most expensive travel plans, we need to find the z-score corresponding to the 95th percentile of the normal distribution. This can be done using a standard normal distribution table or calculator, and we find that the z-score is approximately 1.645. Then, we can use the formula x = μ + zσ, where x is the value we want to find, μ is the mean, σ is the standard deviation, and z is the z-score we just found. Plugging in the values, we get x = 749 + 1.645(225) = $1,100.13. Therefore, the Labor Day weekend expenses for 5% of the families with the most expensive travel plans is about $1,100.13 or higher.

Step-by-step explanation:

To find MDG, we need to calculate the length of line segment DG.

Using the distance formula, the length of a line segment between two points (x1, y1) and (x2, y2) is given by:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

Let's calculate the length of line segment DG:

DG = √((-4 - 2)^2 + (9 - 5)^2)

= √((-6)^2 + (4)^2)

= √(36 + 16)

= √52

= 2√13

Therefore, MDG is equal to 2√13.

Now, let's analyze the line segments DE and DG:

Line segment DE: The coordinates of D are (2, 5) and the coordinates of E are (-4, -4). By calculating the length of DE using the distance formula, we can determine the length of DE.

DE = √((-4 - 2)^2 + (-4 - 5)^2)

= √((-6)^2 + (-9)^2)

= √(36 + 81)

= √117

= √(9 * 13)

= 3√13

Therefore, the length of line segment DE is 3√13.

Line segment DG: We have already calculated the length of DG as 2√13.

From the calculations, we can conclude that DE and DG have different lengths. DE is 3√13 while DG is 2√13.

In summary, line segments DE and DG have different lengths.
