Answer: y=12x+5

Step-by-step explanation:

Hope it's right

(a)R_(4) = (4.7553 + 3.5355 + 2.092 + 0) × (π/8) ≈ 2.6734. Therefore, R_(4) ≈ 2.6734. (b) The graph and the rectangles can be sketched.(c) The estimate R_(4) is an overestimate. (e) L_(4) = (5 + 4.7553 + 3.5355 + 2.092) × (π/8) ≈ 3.9855. Therefore, L_(4) ≈ 3.9855. The estimate L_(4) is an underestimate.

(a) To estimate the area under the graph of f(x) = 5 cos(x) from x = 0 to x = π/2 using four approximating rectangles and right endpoints, we divide the interval [0, π/2] into four equal subintervals.

The width of each rectangle, Δx, is given by:

Δx = (π/2 - 0) / 4 = π/8

To find the height of each rectangle, we evaluate the function at the right endpoint of each subinterval:

f(π/8) = 5 cos(π/8)

f(π/4) = 5 cos(π/4)

f(3π/8) = 5 cos(3π/8)

f(π/2) = 5 cos(π/2)

Now we can calculate the area of each rectangle and sum them up:

Area of rectangle 1 = f(π/8) × Δx

Area of rectangle 2 = f(π/4) × Δx

Area of rectangle 3 = f(3π/8) × Δx

Area of rectangle 4 = f(π/2) × Δx

R_(4) = (f(π/8) + f(π/4) + f(3π/8) + f(π/2)) × Δx

Let's calculate the values:

f(π/8) ≈ 5 × cos(π/8) ≈ 4.7553

f(π/4) ≈ 5 × cos(π/4) ≈ 3.5355

f(3π/8) ≈ 5 × cos(3π/8) ≈ 2.092

f(π/2) ≈ 5 × cos(π/2) ≈ 0

Δx = π/8

R_(4) = (4.7553 + 3.5355 + 2.092 + 0) × (π/8) ≈ 2.6734

Therefore, R_(4) ≈ 2.6734.

(b) The graph and the rectangles can be sketched as follows:

WebAssign Plot:

 0    π/8    π/4   3π/8   π/2

(c) Since the rectangles are constructed using right endpoints, the estimate R_(4) is an overestimate.

(d) To estimate the area under the graph of f(x) = 5 cos(x) from x = 0 to x = π/2 using four approximating rectangles and left endpoints, we use the same process as before, but this time we evaluate the function at the left endpoint of each subinterval.

The width of each rectangle, Δx, is still π/8.

Now we evaluate the function at the left endpoints:

f(0) = 5 cos(0)

f(π/8) = 5 cos(π/8)

f(π/4) = 5 cos(π/4)

f(3π/8) = 5 cos(3π/8)

Area of rectangle 1 = f(0) × Δx

Area of rectangle 2 = f(π/8) × Δx

Area of rectangle 3 = f(π/4) × Δx

Area of rectangle 4 = f(3π/8) × Δx

L_(4) = (f(0) + f(π/8) + f(π/4) + f(3π/8)) × Δx

Let's calculate the values:

f(0) ≈ 5 × cos(0) ≈ 5

f(π/8) ≈ 5 × cos(π/8) ≈ 4.7553

f(π/4) ≈ 5 × cos(π/4) ≈ 3.5355

f(3π/8) ≈ 5 × cos(3π/8) ≈ 2.092

Δx = π/8

L_(4) = (5 + 4.7553 + 3.5355 + 2.092) × (π/8) ≈ 3.9855

Therefore, L_(4) ≈ 3.9855.

(e) Since the rectangles are constructed using left endpoints, the estimate L_(4) is an underestimate.

To complete a pairwise ranking matrix of 7 events, we need to make a total of 21 pairwise comparisons.What is a pairwise ranking matrix?

A pairwise ranking matrix is a matrix that lists the results of pairwise comparisons. In this type of matrix, each row and column represents a participant, team, or event, and the cell at the intersection of the row and column represents the outcome of a comparison between the two.

A comparison is made between every pair of events, and the result of the comparison is recorded in the matrix. The entries on the main diagonal of the matrix are all zero since an event cannot be compared to itself

.How to calculate the number of pairwise comparisons for 7 events?

To calculate the number of pairwise comparisons for 7 events, we use the formula n(n - 1)/2, where n is the number of events.

So, for 7 events, we have:n(n - 1)/2 = 7(7 - 1)/2= 7(6)/2= 21Therefore, we need to make 21 pairwise comparisons to complete a pairwise ranking matrix of 7 events.

The value of R when A equal 5 is 3.6 and the value of A when R equal 9 is 2 as R is varies inversely to A.

Proportional relationships are relationships between two variables where their ratios are equivalent.

If R is inversely proportional to A.

R ∝ 1/A, then

R = k/A

Where k is the proportionality constant.

Given that;

First, we determine the proportionality constant.

R = k/A

Plug in R = 12 and A = 1.5 and solve for k

k = R × A

k = 12 × 1.5

k = 18

a) The value of R when A = 5 will be;

R = k/A

R = 18 / 5

R = 3.6

b) The value of A when R = 9

R = k/A
R × A = k

A = k/R

A = 18 / 9

A = 2

Answer:

We can start by isolating the variable "h".

5 8 h + 1 1 2 = 5

Subtracting 11/2 from both sides:

5 8 h = 5 - 1 1 2

Simplifying:

5 8 h = 8 1 2

Dividing both sides by 5/8:

h = 8 1 2 ÷ 5 8

Converting the mixed number to an improper fraction:

h = (8 x 8 + 1) ÷ 5 8

h = 65/8

Now, we can convert this fraction to a mixed number:

h = 8 1/8

The Reagan doctrine of American activism in the Third World was most particularly exercised in Nicaragua and Grenada. These countries became focal points of U.S. involvement and intervention.

The Reagan doctrine, implemented during the presidency of Ronald Reagan in the 1980s, aimed to counter Soviet influence and promote American interests in the Third World. This doctrine was characterized by a strong anti-communist stance and support for anti-communist governments and movements. Among the various countries where the Reagan doctrine was applied, Nicaragua and Grenada stand out as prime examples.

In Nicaragua, the Reagan administration actively supported the Contras, a rebel group fighting against the Sandinista government. The Contras were seen as a counterforce to the left-wing Sandinistas, who were aligned with the Soviet Union and Cuba. The United States provided financial and military assistance to the Contras, including covert operations, in an effort to undermine the Sandinista regime.

The surface area of the cone is 30.98 square units.

The circular base of the cone is simply a circle with radius √3. The formula for the area of a circle is A = πr², where r is the radius of the circle. Substituting r with √3, we get A = π(√3)² = 3π. Therefore, the area of the circular base of our cone is 3π.

To find the area of the curved surface, we need to use calculus. We can represent the surface area of a cone as the integral of the circumference of each cross-section of the cone. The circumference of each cross-section can be found using the Pythagorean theorem, which gives us the equation c = √(x² + y²).

Using cylindrical coordinates, we can express ds as ds = r dθ, where θ is the angle around the z-axis, and r is the radius of the cross-section. We can also express c as c = √(r² + z²), where z is the height of the cone, and r is the radius of the cross-section.

Substituting these values into the integral, we get A = ∫(√(r² + z²))(r dθ). Since the cone is bounded by 0 ≤ z ≤ √3, we need to integrate with respect to z first and then with respect to θ. We get A = 2π∫(0 to √3)∫(0 to r(z))(√(r² + z²))r dr dz.

Evaluating this integral gives us the area of the curved surface of the cone, which is approximately equal to 27.85.

Therefore, the total surface area of the cone is the sum of the area of the circular base and the area of the curved surface, which is equal to 30.98 (approximately).

To find a value of x that divides the area bounded by the x-axis and the function 3/(2y^2) = x^3 into two sectors of equal area, we need to solve for x.

The area bounded by the x-axis and the function is given by:

A = ∫(3/(2y^2)) dx from x = 0 to x = x

Using u-substitution with u = 2y^2 and du/dx = 6x^2, we can rewrite the integral as:

A = ∫(3/u) du/6x^2 from u = 0 to u = 2y^2

A = (1/2) ln(u) / 6x^2 from u = 0 to u = 2y^2

A = (1/2) ln(2y^2) / 6x^2 - (1/2) ln(0) / 6x^2

Note that the ln(0) term is undefined and can be ignored since we are only interested in finding the value of x that divides the area into two equal parts.

To find the value of x that divides the area into two equal parts, we set the integral expression equal to half of the total area:

(1/2) ln(2y^2) / 6x^2 = 1/2 ∫(3/(2y^2)) dx from x = 0 to x = a

Simplifying and solving for x, we get:

x = [ln(2y^2) / 9 ∫(3/(2y^2)) dx from x = 0 to x = a)]^(-1/3)

Answer:

  (x, y) = (3, -7)

Step-by-step explanation:

You want to solve these equations, -x+y=-10 and 3x+4y=-19, using elimination.

The "elimination" method of solving a system of equations combines the equations in such a way that one of the variables is eliminated. Here, we can eliminate the x-variable by adding 3 times the first equation to the second:

  3(-x+y) +(3x+4y) = 3(-10) +(-19)

  7y = -49 . . . . . . . . . simplify; note x is eliminated from the equation

  y = -7 . . . . . . . . . . . divide by 7

The value of x can be found from the first equation by substituting for y:

  -x +(-7) = -10

  x = 10 -7 = 3 . . . . . . . add x+10 to both sides

The solution to these equations is (x, y) = (3, -7).

The solution is x=3, y = -7

From the question, we have

-x+y=-10 ...........(i)

3x+4y=-19 ..............(ii)

Multiplying equations (i) by 3, we get

-3x+3y=-30................(iii)

Adding both the equation (ii) and (iii), we get,

3x+4y-3x+3y  = -19-30

⇒7y = -49

⇒y = -7

Substituting the value of y in equation (i), we get

-x+y=-10

⇒-x-7=-10

⇒x=3

Elimination Method:

One method for resolving a system of linear equations is the elimination method. In this approach, the equation in one variable is obtained by either adding or subtracting the equations. We can add the equation to delete a variable if its coefficients are the same and have the opposite sign from the other variables. Similar to this, we can subtract the equation to get the equation in one variable if the coefficients of one of the variables are the same and their signs are the same.

Answer:

$1.5 per container

Step-by-step explanation:

First, subtract the cost of the chips from the total purchase cost. This equals 4.5. Then, divide 4.5 by 3 to find the cost of each individual container of milk. You get 1.5. This means that each container was $1.50. Hope this helps :)

a. To find the probability that exactly four of the contracts experience cost overruns, we use the binomial probability formula:

P(X = 4) = (20 choose 4) * 0.2^4 * (0.8\()^16\)

where "X = the number of contracts that experience cost overruns". Using a calculator, we get:

P(X = 4) ≈ 0.2835

b. To find the probability that fewer than three of the contracts experience cost overruns, we need to find the probability that 0, 1, or 2 contracts experience cost overruns. We can use the binomial probability formula for each of these values and add the probabilities together:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

= (20 choose 0) * 0.2^0 * (0.8)^20 + (20 choose 1) * 0.\(2^1\) * (0.8\()^19\) + (20 choose 2) * 0.\(2^2\) * (0.8\()^18\)

Using a calculator, we get:

P(X < 3) ≈ 0.1792

c. To find the probability that none of the contracts experience cost overruns, we use the binomial probability formula:

P(X = 0) = (20 choose 0) * 0.2^0 * (0.8)^20

Using a calculator, we get:

P(X = 0) ≈ 0.0115

d. The mean number of contracts that experience cost overruns is given by the formula:

μ = n*p

where "n" is the number of contracts sampled (20) and "p" is the probability of a cost overrun (0.2). Thus, we have:

μ = 20 * 0.2

μ = 4

e. The standard deviation of the number of contracts that experience cost overruns is given by the formula:

The fraction  43/25 as a percentage is 34.4%.

To convert a fraction to a percent, we can multiply it by 100.

So, 43/25 as a percent is:

(43/25) x 100 = 172/5 %

We can simplify this fraction by dividing both the numerator and denominator by 5:

172/5 ÷ 5/5 = 34.4 %

Therefore, 43/25 as a percent is 34.4%. This means that if we have a group of 25 items, and we take 43 of them, we have taken 34.4% of the total items.

Hello my name is Galaxy and I'll be helping you today. I hope you are having a nice day!

Simplification

To figure out how we can order them, we can first simplify the problems so that we can easily determine its place. We can put the fractions into decimal form so that they are are in one form and will be easy for us to comprehend.

\(\frac{19}{5}=3\frac{4}{5}=3.80\)

We know that \(\frac{1}{5}\) is equal to 0.20 because we know that 1.00 will be equal to 100 in this case and we can divide that by five to get 20 which will be divided back to get to 0.20.

As I've explained how I've simplified the first one, simplifying the others should be a quite similar process, feel free to comment below if you need any assistance with this.

\(\frac{19}{5}=3.80\\1.62=1.62\\\frac{-14}{3}=-4.6667\\ -0.5=-0.5\)

(Everything simplified to decimal form.)

We can now proceed to ordering them.

Ordering

Ordering decimals doesn't have to be as hard as it looks, we know that as per the number line a number that is more negative (e.g. -37) will be less than (e.g. -5) as it is closer to the number 0.

Now that we know how to order the negative numbers, we can order them into order, and for ordering the positive numbers, we should already know how to do that.

So, now, in order from Greatest to Least. We can order them by what I said above.

\(3.80>1.62>-0.5>-4.666\)

We can convert the numbers back into their original form by looking at how we converted them in the Simplification section.

Final Answer

After converting them into a way that we can comprehend, we get our final answer in terms of greatest to least as:

\(\frac{19}{5}>1.62>-0.5>\frac{-14}{3}\)
