The value of sink in triangle is 0.64.

KEF is a right angled triangle.

We have to find the value of sink.

From the triangle , KE is 105, EF is 88 and KF is 137.

We know that sine function is a ratio of opposite side and hypotenuse.

The opposite side of k is EF which is 88.

Hypotenuse us 137.

Sink=88/137

If the order of integration of II ponosen f(x) dxdy is reversed as f(x,y) dydx and (0) +0,6)... then F14,1)

Answers

To find the value of F(14,1) for the double integral with reversed order of integration and limits of integration (0 to 0.6), we need to express the integral in terms of the new order of integration.

The given integral is:

∬(0 to 0.6) f(x) dxdy

When we reverse the order of integration, the limits of integration also change. In this case, the limits of integration for y would be from 0 to 0.6, and the limits of integration for x would depend on the function f(x).

Let's assume that the limits of integration for x are a and b. Since we don't have specific information about f(x), we cannot determine the exact limits without additional context. However, I can provide you with the general expression for the reversed order of integration:

∬(0 to 0.6) f(x) dxdy = ∫(0 to 0.6) ∫(a to b) f(x) dy dx

To evaluate F(14,1), we need to substitute the specific values into the integral expression. Unfortunately, without additional information or constraints for the function f(x) or the limits of integration, it is not possible to provide an exact value for F(14,1).

The question is incomplete but you can use these steps to get your answer.

Government economists in a certain country have determined that the demand equation for soybeans is given by
p = f(x) = 53/(2x^2)+1 where the unit price p is expressed in dollars per bushel and x, the quantity demanded per year, is measured in billions of bushels. The economists are forecasting a harvest of 2.1 billion bushels for the year, w a possible error of 10% in their forecast. Use differentials to approximate the corresponding error in the predicted price per bushel of soybeans. (Round your answer to one decimal place.)

Answers

The approximate error in the predicted price per bushel of soybeans is approximately -0.1 dollars per bushel.

To approximate the corresponding error in the predicted price per bushel of soybeans, we can use differentials. Given that the quantity demanded per year is x = 2.1 billion bushels and there is a possible error of 10% in the forecast, we need to determine the corresponding error in the predicted price per bushel.

First, let's calculate the predicted price per bushel based on the demand equation:

p = f(x) = 53/(2x^2) + 1

Substituting x = 2.1 billion bushels into the equation:

p = 53/(2(2.1)^2) + 1

Calculating the predicted price per bushel:

p ≈ 5.6746 dollars per bushel

Next, let's calculate the differential of the demand equation:

df(x) = f'(x) dx

Where f'(x) is the derivative of f(x) with respect to x, which we can find by differentiating the demand equation:

f(x) = 53/(2x^2) + 1

Taking the derivative:

f'(x) = -53/(x^3)

Now, we can calculate the error in the predicted price per bushel by considering the possible error in the quantity demanded:

dx = 0.1x

Substituting x = 2.1 billion bushels and dx = 0.1(2.1) billion bushels:

dx ≈ 0.21 billion bushels

Finally, we can use the differential to approximate the corresponding error in the predicted price per bushel:

dp ≈ f'(x) dx

dp ≈ (-53/(x^3)) (0.21)

Substituting x = 2.1 billion bushels:

dp ≈ (-53/(2.1^3)) (0.21)

Calculating the approximate error in the predicted price per bushel:

dp ≈ -0.1038 dollars per bushel

The conclusion of this topic is that by using differentials, we can approximate the corresponding error in the predicted price per bushel of soybeans based on the forecasted harvest quantity. In this case, the demand equation for soybeans, along with the forecasted harvest of 2.1 billion bushels with a possible error of 10%, allows us to calculate the approximate error in the predicted price.

The eigenvalues of the coefficient matrix can be found by inspection or factoring. Apply the eigenvalue method to find a general solution of the system. 7 3 7 = 3 11 3 y 7 3 7

Answers

The general solution of the system can be found using the eigenvalue method by applying inspection or factoring to the coefficient matrix.

To find eigenvalues, we take the determinant of the coefficient matrix and set it equal to zero. This gives us a polynomial equation whose roots are the eigenvalues. For this system, the coefficient matrix is

7 3 7

3 11 3

7 3 7

Taking the determinant, we get

7(11)(7) + 3(3)(7) + 7(3)(-3) - 7(11)(7) - 3(7)(7) - 7(3)(3) = 0

Simplifying this gives us

(7 - λ)[(11 - λ)(7 - λ) - 3(3)] - 3[3(7 - λ) - 7(3)] + 7[3(3) - 11(7 - λ)] = 0

Factoring and solving for λ, we get

λ₁ = 15, λ₂ = 1, λ₃ = -2

Now we can use the eigenvalues to find eigenvectors, which will be the basis of our general solution. For each eigenvalue λᵢ, we solve the equation (A - λᵢI)x = 0, where A is the coefficient matrix and I is the identity matrix.

This gives us a system of linear equations, which we can solve using row reduction.

The resulting vector is the eigenvector corresponding to λᵢ.

For this system, we get

λ₁ = 15: eigenvector [1, 3, 1]

λ₂ = 1: eigenvector [-1, 0, 1]

λ₃ = -2: eigenvector [1, -3, 1]

These eigenvectors form the basis of our general solution, which is

x(t) = c₁[1, 3, 1]e^(15t) + c₂[-1, 0, 1]e^(t) + c₃[1, -3, 1]e^(-2t)

a. find a formula modeling the amount of mathium-314 left after t years.
b. how much mathium-314 is left after 7 years?
c. how much time does it take for the mathium-314 sample to decay to 10 grams?

Answers

It will take approximately 19.15 years for the mathium-314 sample to decay to 10 grams.

a. The formula modeling the amount of mathium-314 left after t years can be expressed using the half-life concept as:

N(t) = N₀ * (1/2)^(t / T₁/₂)

Where:

N(t) is the amount of mathium-314 remaining after t years,

N₀ is the initial amount of mathium-314 (100 grams in this case),

T₁/₂ is the half-life of mathium-314 (4 years).

b. To find the amount of mathium-314 left after 7 years, we can substitute t = 7 into the formula from part (a):

N(7) = 100 * (1/2)^(7 / 4)

N(7) ≈ 100 * (1/2)^(1.75)

N(7) ≈ 100 * 0.316

N(7) ≈ 31.6 grams

Therefore, after 7 years, approximately 31.6 grams of mathium-314 will be left.

c. To determine the time it takes for the mathium-314 sample to decay to 10 grams, we can rearrange the formula from part (a) and solve for t:

10 = 100 * (1/2)^(t / 4)

Dividing both sides by 100:

0.1 = (1/2)^(t / 4)

Taking the logarithm (base 1/2) of both sides:

log(0.1) = t / 4 * log(1/2)

Using the change of base formula:

log(0.1) / log(1/2) = t / 4

Simplifying the equation:

t ≈ 4 * (log(0.1) / log(1/2))

Using a calculator:

t ≈ 4 * (-3.3219 / -0.6931)

t ≈ 4 * 4.7875

The function F(t) depends on the specific value of v. Given that r'(t) = <12t, e^(0.25t), vt> and r(0) = <2, 1, 5>, we can find the function r(t) by integrating r'(t) with respect to t. The function F(t) will depend on the specific values of v and the integration constants.

To find the function r(t), we need to integrate each component of r'(t) with respect to t. Integrating the first component: ∫(12t) dt = 6t^2 + C1. Integrating the second component: ∫(e^(0.25t)) dt = 4e^(0.25t) + C2. Integrating the third component: ∫(vt) dt = (1/2)vt^2 + C3

Putting it all together, we have: r(t) = <6t^2 + C1, 4e^(0.25t) + C2, (1/2)vt^2 + C3>. Given that r(0) = <2, 1, 5>, we can substitute t = 0 into the components of r(t) and solve for the integration constants:

6(0)^2 + C1 = 2

4e^(0.25(0)) + C2 = 1

(1/2)v(0)^2 + C3 = 5

Simplifying the equations: C1 = 2, C2 + 4 = 1, C3 = 5

From the second equation, we find C2 = -3, and substituting it into the third equation, we find C3 = 5. Therefore, the function r(t) is: r(t) = <6t^2 + 2, 4e^(0.25t) - 3, (1/2)vt^2 + 5>

Answers

The Cartesian coordinates corresponding to the polar coordinates 7, 7π/6 are approximately (-3.5, 6.062).

To convert polar coordinates to Cartesian coordinates, we can use the following formulas:

x = r * cos(θ)

y = r * sin(θ)

In this case, the polar coordinates are given as 7, 7π/6.

Plugging these values into the formulas, we have:

x = 7 * cos(7π/6)

y = 7 * sin(7π/6)

To evaluate these trigonometric functions, we need to convert the angle from radians to degrees. The angle 7π/6 is approximately equal to 210 degrees. Using the trigonometric identities, we can rewrite the above equations as:

x = 7 * cos(210°)

y = 7 * sin(210°)

Evaluating the cosine and sine of 210 degrees, we find:

x ≈ 7 * (-0.866) ≈ -3.5

y ≈ 7 * (-0.5) ≈ -3.5

Answers

To determine the mean of the test, we can use the information given about the scores falling two standard deviations above and below the mean.

Let's denote the mean of the test as μ and the standard deviation as σ.

We are given:
48 falls two standard deviations above the mean, so 48 = μ + 2σ.
28 falls two standard deviations below the mean, so 28 = μ - 2σ.

To solve for the mean μ, we can set up a system of equations with these two equations:

48 = μ + 2σ
28 = μ - 2σ

Adding the two equations together eliminates the σ term:
48 + 28 = μ + 2σ + μ - 2σ
76 = 2μ

Dividing both sides by 2 gives us the value of the mean μ:
76/2 = 2μ/2
38 = μ

Therefore, the mean of the test is 38.

The line integral ∫(x dx + y dy) over the path C can be evaluated using two methods: (a) directly, by parameterizing the path and integrating, and (b) using Green's Theorem, by converting the line integral to a double integral over the region enclosed by the path.

(a) To evaluate the line integral directly, we can break the path C into its three segments: the line segment from (0, 4) to (0, 0), the line segment from (0, 0) to (2, 0), and the curve y = 4 - x^2 from (2, 0) to (0, 4). For each segment, we parameterize the path and compute the integral. Then, we add up the results to obtain the total line integral.

(b) Using Green's Theorem, we can convert the line integral to a double integral over the region enclosed by the path C. The line integral of (x dx + y dy) along C is equal to the double integral of (∂Q/∂x - ∂P/∂y) dA, where P and Q are the components of the vector field associated with x and y, respectively. By evaluating this double integral, we can find the value of the line integral.

Both methods will yield the same result for the line integral, but the choice of method depends on the specific problem and the available information. Green's Theorem can be more efficient for certain cases where the path C encloses a region with a simple boundary, as it allows us to convert the line integral into a double integral.

Answers

The dimensions of the box that minimise the amount of material used are a square base with a side length of 70 cm and a height of 171500 / 70² cm.

To obtain the formula for the surface area of the box in terms of the length of one side of the square base, we can use the volume formula and express the height of the box in terms of the side length.

Let's denote the side length of the square base as s. The volume of the box is given as 171500 cm³, so we have:

Volume = s² * h = 171500

We can express the height, h, in terms of s by dividing both sides of the equation by s²:

h = 171500 / s²

The surface area of the box is the sum of the area of the square base and the area of the four sides. The area of the square base is s², and the area of each side is given by s times the height, which is s * h.

Therefore, the surface area, A(s), is:

A(s) = s² + 4s * h

Substituting the expression for h we found earlier:

A(s) = s² + 4s * (171500 / s²)

Simplifying further:

A(s) = s² + (686000 / s

This is the formula for the surface area of the box in terms of the side length, s.

Next, let's obtain the derivative, A'(s), to find critical points:

A'(s) = 2s - (686000 / s²)

To calculate when the derivative equals zero, we set A'(s) = 0:

2s - (686000 / s²) = 0

To simplify the equation, let's multiply both sides by s²:

2s³ - 686000 = 0

Solving for s³:

s³ = 686000 / 2

s³ = 343000

Taking the cube root of both sides:

s = ∛343000

s = 70

So, A'(s) = 0 when s = 70.

Now, let's get the second derivative, A''(s):

A''(s) = 2 + (1372000 / s³)

To evaluate A''(s) at s = 70:

A''(70) = 2 + (1372000 / 70³)

A''(70) = 2 + (1372000 / 343000)

A''(70) = 2 + 4

A''(70) = 6

Since A''(70) is positive, this indicates that the graph of A(s) is concave up around s = 70, which means that the critical point s = 70 gives a local minimum for the surface area.

A patient who weighs 170 lb has an order for an IVPB to infuse at the rate of 0.05 mg/kg/min. The medication is to be added to 100 mL NS and infuse over 30 minutes. How many grams of the drug will the patient receive?

Answers

The patient will receive approximately 0.11568 grams of the drug. This is calculated by converting the patient's weight to kilograms, multiplying it by the infusion rate, and then multiplying the dosage per minute by the infusion duration in minutes.

To determine the grams of the drug the patient will receive, we need to do the follows:

1: Convert the patient's weight from pounds to kilograms.

170 lb ÷ 2.2046 (conversion factor lb to kg) = 77.112 kg (rounded to three decimal places).

2: Calculate the total dosage of the drug in milligrams (mg) by multiplying the patient's weight in kilograms by the infusion rate.

Total dosage = 77.112 kg × 0.05 mg/kg/min = 3.856 mg/min.

3: Convert the dosage from milligrams to grams.

3.856 mg ÷ 1000 (conversion factor mg to g) = 0.003856 g.

4: Determine the total amount of the drug the patient will receive by multiplying the dosage per minute by the infusion duration in minutes.

Total amount of drug = 0.003856 g/min × 30 min = 0.11568 g.

what conditions, if any, must be set forth in order for a b to be equal to n(a u b)?

Answers

In order for B to be equal to (A ∪ B), certain conditions must be satisfied. These conditions involve the relationship between the sets A and B and the properties of set union.

To determine when B is equal to (A ∪ B), we need to consider the properties of set union. The union of two sets, denoted by the symbol "∪," includes all the elements that belong to either set or both sets. In this case, B would be equal to (A ∪ B) if B already contains all the elements of A, meaning B is a superset of A.

In other words, for B to be equal to (A ∪ B), B must already include all the elements of A. If B does not include all the elements of A, then the union (A ∪ B) will contain additional elements beyond B.

Therefore, the condition for B to be equal to (A ∪ B) is that B must be a superset of A.

To summarize, B will be equal to (A ∪ B) if B is a superset of A, meaning B contains all the elements of A. Otherwise, if B does not contain all the elements of A, then (A ∪ B) will have additional elements beyond B.

Write an expression for the area bounded by r = 3 - Cos4x

Answers

The expression for the area bounded by the polar curve r = 3 - cos(4x) can be obtained by integrating the area element dA over the region enclosed by the curve.

To calculate the area, we can use the formula A = ∫[θ₁, θ₂] (1/2) r² dθ, where θ₁ and θ₂ represent the angular limits of the region. In this case, the range of θ would be determined by the values of x that satisfy 0 ≤ x ≤ 2π. Therefore, the expression for the area bounded by the curve r = 3 - cos(4x) is A = ∫[0, 2π] (1/2) (3 - cos(4x))² dθ.

Eliminate the parameter and write the resulting rectangular
equation whose graph represents the curve.

Answers

To eliminate the parameter, we can use the trigonometric identities:

sec(theta) = 1/cos(theta)

tan(theta) = sin(theta)/cos(theta)

Substituting these identities into the given equations, we have:

x = 3/(1/cos(theta)) = 3cos(theta)

y = (sin(theta))/(2cos(theta)) = (1/2)sin(theta)/cos(theta) = (1/2)tan(theta)

Now we can express y in terms of x:

y = (1/2)tan(theta) = (1/2)(y/x) = (1/2)(y/(3cos(theta))) = (1/6)(y/cos(theta))

Multiplying both sides by 6cos(theta), we get:

6cos(theta)y = y

Now we can substitute x = 3cos(theta) and simplify:

6x = y

This is the resulting rectangular equation that represents the curve.

Ex 1 A football factory has a fixed operational cost of $20,000 and spends an additional $1 per football produced. The maximum sale price of each football is set at $21, which will be decreased by 0.1

Answers

The calculation for the number of footballs needed to break even is explained in the following paragraph.

To calculate the number of footballs needed to break even, we need to consider the total cost and the revenue generated from selling the footballs. The total cost consists of the fixed operational cost of $20,000 and the variable cost of $1 per football produced.

Let's denote the number of footballs produced as x. The total cost can be calculated as follows: Total Cost = Fixed Cost + Variable Cost per Unit * Number of Units = $20,000 + $1 * x.

The revenue generated from selling the footballs is the product of the sale price and the number of units sold. However, in this case, the maximum sale price of each football is set at $21, but it will be decreased by $0.1. So the sale price per unit can be expressed as $21 - $0.1 = $20.9.

To break even, the total revenue should equal the total cost. Therefore, we can set up the equation: Total Revenue = Sale Price per Unit * Number of Units = $20.9 * x.

By setting the total revenue equal to the total cost and solving for x, we can find the number of footballs needed to break even.

Find the length and direction (when defined) of u xv and vxu. u= -2i+6j-10k, v=-i +3j-5k |uxv = (Simplify your answer.)

Answers

To find the length and direction of the cross product u × v, where u = -2i + 6j - 10k and v = -i + 3j - 5k, we can calculate the cross product and then determine its magnitude and direction.

The cross product u × v is given by the formula: u × v = |u| |v| sin(θ) n

where |u| and |v| are the magnitudes of u and v, respectively, θ is the angle between u and v, and n is the unit vector perpendicular to both u and v.

To calculate the cross product, we can use the determinant method:

u × v = (6 * (-5) - (-10) * 3)i + ((-2) * (-5) - (-10) * (-1))j + ((-2) * 3 - 6 * (-1))k

= (-30 + 30)i + (-10 + 10)j + (-6 - 6)k

= 0i + 0j + (-12)k

= -12k

Therefore, the cross product u × v simplifies to -12k.

Now, let's find the length of u × v:

|u × v| = |(-12)k|

= 12

So, the length of u × v is 12.

As for the direction, since the cross product u × v is a vector along the negative k-axis, its direction can be expressed as -k.

Therefore, the length of u × v is 12, and its direction is -k.

angles. (Round you

Answers

To find the remaining side and one of the other angles of a triangle, we can use the Law of Cosines. The Law of Cosines relates the lengths of the sides of a triangle to the cosine of one of its angles. The formula is given by:

c^2 = a^2 + b^2 - 2ab cos(C),

where c represents the length of the side opposite angle C, and a and b represent the lengths of the other two sides.

To find the remaining side, we can rearrange the formula as:

c = sqrt(a^2 + b^2 - 2ab cos(C)).

Once we have the length of the remaining side, we can use the Law of Cosines again to find one of the other angles. The formula is:

cos(C) = (a^2 + b^2 - c^2) / (2ab).

Taking the inverse cosine (arccos) of both sides, we can find the measure of angle C.

In summary, by applying the Law of Cosines, we can find the remaining side of a triangle and one of the other angles. The formula allows us to calculate the length of the side using the lengths of the other two sides and the cosine of the angle. Additionally, we can use the Law of Cosines to determine the measure of the angle by finding the inverse cosine of the expression involving the side lengths.

There are 15 blue marbles, 8 green marbles, and 7 red marbles in a bag. Hanna randomly draws a
marble from the bag. What is the probability that Hanna draws a blue marble?

Answers

Answer:

Step-by-step explanation:

To find the probability that Hanna draws a blue marble, we need to determine the ratio of the number of favorable outcomes (drawing a blue marble) to the total number of possible outcomes (drawing any marble).

The total number of marbles in the bag is the sum of the blue, green, and red marbles:

Total marbles = 15 blue marbles + 8 green marbles + 7 red marbles = 30 marbles

Since Hanna is drawing only one marble, the total number of possible outcomes is 30.

The number of favorable outcomes (drawing a blue marble) is 15 blue marbles.

Therefore, the probability that Hanna draws a blue marble is:

Probability = Number of favorable outcomes / Total number of possible outcomes

          = 15 blue marbles / 30 marbles

          = 0.5

So, the probability that Hanna draws a blue marble is 0.5 or 50%.
