Answer:

\(\sf c = -4\)  and  \(\sf b = -6\)

Explanation:

using the formula: \(\sf x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a}\)

Here the a = 1

using the equation:

\(3 \pm\sqrt{13}= \frac{ -b \pm \sqrt{b^2 - 4(1)c}}{2(1)}\)

\(6 \pm2\sqrt{13}= -b \pm \sqrt{b^2 - 4(1)c}}\)

matching the coefficients: b = - 6

find c:

\(6 \pm2\sqrt{13}= -(-6) \pm \sqrt{(-6)^2 - 4(1)c}}\)

\(6 \pm2\sqrt{13}= 6 \pm \sqrt{36 - 4c}}\)

\(\sf 6 \pm\sqrt{52}= 6 \pm \sqrt{36 - 4c}}\)

\(\sf 36-4c = 52\)

\(\sf -4c = 52-36\)

\(\sf -4x = 16\)

The number of polio vaccinations is 32  and measles vaccination is 28

Let p represent the number of polio vaccines and let m represent the number of measles vaccines.

We know that each polio vaccine consists of 4 doses, and each measles vaccine consists of 2 doses.

Dr. Potter gave a total of 60 vaccinations last year. Therefore, the sum of the number of polio vaccines and measles vaccines must total 60. Therefore:

p+m=60

Together, they consisted of 184 doses.

Since each polio vaccine has 4 doses, the amount of doses for p polio vaccines is 4p.

And since each measles vaccine has 2 doses, the amount of doses for m measles vaccines is 2m.

So:

4p+2m=184

We now have a system of equations:

p+m=60

4p+2m=184

We can solve using elimination. Let’s multiply the first equation by -2. So:

-2p-2m=-120

Now, we can add this to the second equation. Hence:

(-2p+4p)+(-2m+2m)=(-120+184)

2p=64

p=32

Therefore, Dr. Potter gave out 32 polio vaccinations

p+m=60

By the first equation:

p+m=60

Substitute 32 for p to get

32+m=60

m=60-32

m=28

So, 28 measles vaccinations were given out.

The curvature (k) of the space curve r(t) = (cos^3(t))i + (sin^3(t))j is given by k = 3(cos(t)sin(t))^2.

To find the curvature of a space curve given by r(t) = (cos^3(t))i + (sin^3(t))j, we need to calculate the magnitude of the curvature vector.

The curvature vector is given by k(t) = |(dT/ds)|, where T is the unit tangent vector and ds is the arc length parameter.

First, we find the unit tangent vector T(t) by differentiating the position vector r(t) with respect to t and normalizing it:

r'(t) = (-3cos^2(t)sin(t))i + (3sin^2(t)cos(t))j

| r'(t) | = sqrt((-3cos^2(t)sin(t))^2 + (3sin^2(t)cos(t))^2)

| r'(t) | = 3|cos(t)sin(t)| = 3|sin(t)cos(t)| = 3(cos(t)sin(t))

Next, we differentiate T(t) with respect to t to find dT/ds:

dT/ds = dT/dt * dt/ds

Since dt/ds is the magnitude of the velocity vector, which is given by | r'(t) |, we have:

dT/ds = (1/| r'(t) |) * r''(t)

Differentiating r'(t) with respect to t, we get:

r''(t) = (-6cos^3(t) + 6sin^3(t))i + (6sin^3(t) - 6cos^3(t))j

Substituting the values into the expression for dT/ds:

dT/ds = (1/3(cos(t)sin(t))) * [(-6cos^3(t) + 6sin^3(t))i + (6sin^3(t) - 6cos^3(t))j]

dT/ds = (-2cos^2(t) + 2sin^2(t))i + (2sin^2(t) - 2cos^2(t))j

Finally, we find the magnitude of dT/ds, which gives us the curvature:

| dT/ds | = sqrt[(-2cos^2(t) + 2sin^2(t))^2 + (2sin^2(t) - 2cos^2(t))^2]

| dT/ds | = sqrt[4(cos^4(t) - 2cos^2(t)sin^2(t) + sin^4(t)) + 4(cos^4(t) - 2cos^2(t)sin^2(t) + sin^4(t))]

| dT/ds | = sqrt[8(cos^4(t) - 2cos^2(t)sin^2(t) + sin^4(t))]

Simplifying further, we have:

| dT/ds | = sqrt[8(cos^2(t) - cos^2(t)sin^2(t) + sin^2(t))sin^2(t)]

| dT/ds | = sqrt[8(sin^2(t) - cos^2(t)sin^2(t))sin^2(t)]

| dT/ds | = sqrt[8(sin^2(t)(1 - cos^2(t)))]

| dT/ds | = sqrt[8(sin^2(t)sin^2(t))]

| dT/ds | =

sqrt[8(sin^4(t))]

| dT/ds | = 2sqrt(2)(sin^2(t))

Therefore, the curvature k of the space curve r(t) = (cos^3(t))i + (sin^3(t))j is given by k = 3(cos(t)sin(t))^2.

If you want to arrange your textbooks on shelves with at least two textbooks on each shelf, and the order does not matter, we can calculate the number of ways using combinations.

Let's consider the problem of arranging textbooks on shelves with at least two textbooks on each shelf. Since the order does not matter, we are dealing with combinations.

To find the number of ways, we can divide the problem into cases based on the number of shelves used. We will consider the possibilities of having 2, 3, 4, or 5 shelves.

Case 1: 2 shelves

In this case, you can choose 2 shelves out of the total number of shelves available. The number of ways to choose 2 shelves out of 5 shelves is given by the combination formula:

C(5, 2) = 5! / (2! * (5-2)!) = 10

Case 2: 3 shelves

In this case, you can choose 3 shelves out of the total number of shelves available. The number of ways to choose 3 shelves out of 5 shelves is given by the combination formula:

C(5, 3) = 5! / (3! * (5-3)!) = 10

Case 3: 4 shelves

In this case, you can choose 4 shelves out of the total number of shelves available. The number of ways to choose 4 shelves out of 5 shelves is given by the combination formula:

C(5, 4) = 5! / (4! * (5-4)!) = 5

Case 4: 5 shelves

In this case, you have no choice but to use all 5 shelves. Therefore, there is only 1 way to arrange the textbooks in this case.

Finally, to find the total number of ways to arrange the textbooks, we sum up the results from each case:

Total number of ways = 10 + 10 + 5 + 1 = 26

Therefore, there are 26 ways to arrange your textbooks on shelves, ensuring that each shelf has at least two textbooks, and the order does not matter.

Vectors in S satisfy  3xy - 7z = 0 since substituting the components of x = (r²s, 3rs, s) into equation gives 3(r²s)(3rs) - 7s = 9r²s² - 7s = s(9r²s - 7) = 0. This shows vectors in S lie on plane defined by equation 3xy - 7z = 0.

To show that S is a subspace of ℝ³, where S is defined as the set of vectors x = (r²s, 3rs, s) with r, s ∈ ℝ, we need to demonstrate that S satisfies three conditions: it contains the zero vector, it is closed under vector addition, and it is closed under scalar multiplication. Additionally, we need to show that the vectors in S lie on the plane with the equation 3xy - 7z = 0.

First, we verify that S contains the zero vector. Substituting r = 0 and s = 0 into the vector x, we obtain (0, 0, 0), which is the zero vector.

Next, we check if S is closed under vector addition. Let x₁ = (r₁²s₁, 3r₁s₁, s₁) and x₂ = (r₂²s₂, 3r₂s₂, s₂) be two arbitrary vectors in S. Their sum, x = x₁ + x₂, can be expressed as (r₁²s₁ + r₂²s₂, 3r₁s₁ + 3r₂s₂, s₁ + s₂). Since r₁, r₂, s₁, and s₂ are real numbers, the sum of the corresponding components is also a real number. Hence, S is closed under vector addition.

Lastly, we need to show that S is closed under scalar multiplication. Let x = (r²s, 3rs, s) be an arbitrary vector in S and c be a real number. The scalar multiple c · x can be written as (c · r²s, c · 3rs, c · s), which is also in the form of a vector in S. Thus, S is closed under scalar multiplication.

Furthermore, the vectors in S satisfy the equation 3xy - 7z = 0 since substituting the components of x = (r²s, 3rs, s) into the equation gives 3(r²s)(3rs) - 7s = 9r²s² - 7s = s(9r²s - 7) = 0. This shows that the vectors in S lie on the plane defined by the equation 3xy - 7z = 0.

Therefore, based on the verification of the three conditions for a subspace and the vectors satisfying the given equation, S is a subspace of ℝ³.

Answer:

The longer rope is 31.9882ft long or 975cm.

The shorter rope is 31.0039ft long or 945cm.

Step-by-step explanation:

Convert 63ft to cm, which is 1920cm.

Divide 1920cm by 2. Which give 960cm. So if both sides were cut equally this would be the length but one is 15cm longer.

So we add 15cm to 960 cm, which is 975cm, thus thats the length for the longer rope.

To find the shorter one we just subtract 15cm from 960cm and we get 945cm.

Convert both final measurements back to ft if required.

The total Quantity demanded is:Q = 9 * (200 - P) + 92On simplifying this expression, we get:Q = 1828 - 9P

Substituting this value of Q in the profit function, we get:Pi = (198 - (1828 - 9P)) * qiOn

simplifying this expression, we get:Pi = (10P - 1630) * qi

This is the profit function for each firm in the industry.

The given market demand function for Coca-Cola and Pepsi is Q(p) = 200 - P. Here, Q denotes the total quantity demanded and P represents the price of the product.

The cost function for each of the two firms is C(qi) = 2q_i where q_i denotes the quantity produced by the ith firm.

Now, we need to determine the profit function for each firm in the industry.

To find out the profit function for each firm, we need to calculate the revenue function and subtract the cost function from it.The revenue function is the product of price and quantity. Therefore, the revenue function for both firms is:Ri = p * qi where Ri is the revenue of ith firm.

The price of each firm is determined by the market demand function as follows:p = 200 - QSubstituting this value of p in the above expression, we get:Ri = (200 - Q) * qi

Now, we need to calculate the profit function for each firm. It is given by the following expression:Pi = Ri - Ci where Pi is the profit of ith firm and Ci is the cost of production of ith firm. Substituting the value of Ri and Ci in the above equation, we get:

Pi = (200 - Q) * qi - 2qiOn simplifying this expression, we get:Pi = (198 - Q) * qiThis is the profit function for both firms in the industry. It is a function of quantity produced by each firm (qi) and total quantity demanded (Q). Hence, the profit of each firm depends on the total quantity demanded and the quantity produced by the firm.

The given demand function is Q(p) = 200 - P. Here, we are given Q = 9₁ + 92.

Therefore, the total quantity demanded is:Q = 9 * (200 - P) + 92On simplifying this expression, we get:Q = 1828 - 9P

Substituting this value of Q in the profit function, we get:Pi = (198 - (1828 - 9P)) * qiOn

simplifying this expression, we get:Pi = (10P - 1630) * qi

The area under the normal curve to the right of μ equals 0 . Thus, option C is correct.

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

The area under the normal curve to the right of μ equals 0, which means that the entire normal distribution is to the left of μ.

This is because the normal distribution is a symmetric probability distribution, and so half of the area is to the left of the mean and half is to the right. Therefore, if all the area is to the left of μ, then none is to the right.

Option A, σ, represents the standard deviation of the normal distribution and is not related to the area to the right of μ.

Option B, 1/2, is incorrect because it represents the area to the right of the median, which is not necessarily the same as the mean for a normal distribution.

To find an expression for the area under the graph of f(x) = x^2 * e^x using the right endpoints as a limit, we can use the definition of the Riemann sum.

The Riemann sum with the right endpoints is given by:

A = lim(n → ∞) ∑[i=1 to n] f(xi) * Δx

where A represents the area under the curve, n is the number of subintervals, xi represents the right endpoint of each subinterval, and Δx is the width of each subinterval.

In this case, the function is f(x) = x^2 * e^x, and the interval of integration is 0 ≤ x ≤ 5.

Using the right endpoints, we can divide the interval [0, 5] into n equal subintervals of width Δx = 5/n. The right endpoints of these subintervals will be xi = i * Δx, where i ranges from 1 to n.

Thus, the expression for the area under the graph of f(x) as a limit is:

To buy four pieces of candy from the odd owner, you need to have a specific number of pennies and dimes.

To buy candy from the odd owner, you need to use multiples of four. The problem states that each piece of candy weighs g, so to buy four pieces, you need g. The owner only accepts payment in pennies and dimes. Each penny weighs g, and each dime weighs g.

To figure out how many pennies and dimes you need to buy four pieces of candy, you can use the weight information. Since you have g of pennies, and each penny weighs g, you can calculate the number of pennies. This can be done by dividing the total weight of the pennies (g) by the weight of each penny (g). The result will give you the number of pennies you have.

Similarly, you have g of dimes, and each dime weighs g. By dividing the total weight of the dimes (g) by the weight of each dime (g), you can find the number of dimes you have.

Now, let's say the number of pennies you need to buy four pieces of candy is P, and the number of dimes you need is D. To find the values of P and D, you can set up an equation:

P * penny weight + D * dime weight = g.

This equation represents the total weight of the pennies and dimes you have.

Solving this equation will give you the values of P and D, which represent the number of pennies and dimes you need to buy four pieces of candy.

To buy four pieces of candy from the odd owner, you need to have a specific number of pennies and dimes. By using the weight information provided in the problem, you can calculate the number of pennies and dimes you have. You then set up an equation to determine the values of P and D, representing the number of pennies and dimes needed. Solving this equation will give you the required values, allowing you to conclude the number of pennies and dimes needed to buy four pieces of candy.
