Answer:

Domain: {-3, -2, 0, 2}
Range: {5, 4, 9}

This is a function.

The relation is not linear.

Step-by-step explanation:

I didn't know which one you wanted so I put what I knew.

Have a great day thx for your inquiry :)

The function f(n) = 2n^4 + 5n^2 - 3 is O(g(n)), where g(n) = n^4, with C = 8 and n0 = 1.

This means that there exist constants C and n0 such that f(n) ≤ C * g(n) for all n ≥ n0.

To prove that f(n) = 2n^4 + 5n^2 - 3 is O(g(n)), we need to find a function g(n) and two constants C and n0 such that f(n) ≤ C * g(n) for all n ≥ n0.

Let's choose g(n) = n^4. Now we need to find constants C and n0 that satisfy f(n) ≤ C * g(n) for all n ≥ n0.

Step 1: Simplify f(n) and express it in terms of g(n):

f(n) = 2n^4 + 5n^2 - 3

Step 2: Choose a constant C:

Let's choose C = 8, which is greater than the coefficient of the highest power of n in f(n).

Step 3: Choose a value for n0:

To find n0, we need to solve the inequality f(n) ≤ C * g(n) for n:

2n^4 + 5n^2 - 3 ≤ 8n^4

6n^4 - 5n^2 - 3 ≥ 0

By plotting the graph of the inequality, we can see that it holds true for all n ≥ 1. Therefore, we choose n0 = 1.

Step 4: Verify the inequality for all n ≥ n0:

For n ≥ 1, we have:

2n^4 + 5n^2 - 3 ≤ 8n^4

2n^4 + 5n^2 - 3 - 8n^4 ≤ 0

-6n^4 + 5n^2 - 3 ≤ 0

By factoring the expression, we have:

(n^2 - 1)(-6n^2 + 3) ≤ 0

Since (n^2 - 1) ≥ 0 for n ≥ 1 and (-6n^2 + 3) ≤ 0 for all n, the inequality holds true for all n ≥ n0 = 1.

Therefore, we have shown that f(n) = 2n^4 + 5n^2 - 3 is O(g(n)), where g(n) = n^4, with C = 8 and n0 = 1.

Answer:

52 adult tickets

Step-by-step explanation:

We can write a system of equations to solve this:

Let x represent child tickets and y represent adult tickets.

x+y=146

5.4x+9.5y=1001.6

Solve for y in the first equation:

x+y=146

subtract x from both sides

y=146-x

Substitute this into the second equation:

5.4x+9.5(146-x)=1001.6

simplify

5.4x+1387-9.5x=1001.6

combine like terms

-4.1x + 1387=1001.6

subtract 1387 from both sides

-4.1x=-385.4

divide both sides by -4.1

x=94

Next, plug in this into the first equation and solve for y (adult tickets).

94+y=146

subtract 94 from both sides

y=52

So, 52 adult tickets were sold that day.

Hope this helps! :)

We assume that the integral of g(x) is convergent. If that's the case, then the integral of f(x) must be convergent as well. We can use the following comparison test to prove it:If f(x) ≤ g(x) for all x ≥ k, and the integral of g(x) is convergent, then the integral of f(x) is also convergent. If the integral of f(x) is divergent, then the integral of g(x) must be divergent.In this case, the function is (c) letter) at + e-x which is a sum of two continuous functions

The cost function for the marginal cost function C′(x)=0.05e0.01x with a fixed cost of $8 is C(x) = 8 + 0.05e0.01x.

The marginal cost function is the derivative of the cost function. It tells us how much the cost of production increases when we produce one more unit of output. In this case, the marginal cost function is C′(x)=0.05e0.01x.

This means that the cost of producing one more unit of output is $0.05e0.01x.

The fixed cost is the cost that is incurred even when no output is produced. In this case, the fixed cost is $8. This means that the total cost of production is $8 plus the marginal cost of production.

Therefore, the cost function for the marginal cost function C′(x)=0.05e0.01x with a fixed cost of $8 is C(x) = 8 + 0.05e0.01x.

Here is a more detailed explanation of how to find the cost function:

The marginal cost function is the derivative of the cost function. This means that we can find the cost function by taking the integral of the marginal cost function. The integral of C′(x)=0.05e0.01x is 8 + 0.05e0.01x. Therefore, the cost function is C(x) = 8 + 0.05e0.01x.

The Marginal Rate of Substitution (MRS) for the given function is equal to -2/sqrt(x). To find the Marginal Rate of Substitution (MRS), we need to take the derivative of the given function with respect to x.

Given: y = 24 - 4(sqrt(x))

Step 1: Differentiate the function y with respect to x.

dy/dx = d/dx(24 - 4(sqrt(x)))

Step 2: Differentiate each term separately using the power rule and chain rule.

dy/dx = 0 - 4(1/2)(x^(-1/2))(1)

Step 3: Simplify the derivative.

dy/dx = -2(x^(-1/2))

Step 4: Rewrite the derivative in terms of MRS.

MRS = dy/dx = -2/sqrt(x)

Therefore, the Marginal Rate of Substitution (MRS) for the given function y = 24 - 4(sqrt(x)) is -2/sqrt(x).

The negative sign indicates that the MRS is inversely related to x, which means as x increases, the MRS decreases. The value of MRS represents the rate at which a consumer is willing to substitute y (the dependent variable) for an incremental change in x (the independent variable). In this case, as x increases, the consumer is willing to substitute less y for the additional units of x.

The maximum and minimum values of the function is f(x, 0) = (x² + 0²) * e^-(x+0) = x² * e

To find the maximum and minimum values of the function f(x, y) = (x² + y²) * e^-(x+y) on the domain D = {(x, y) ∈ R²: x ≥ 0 and y ≥ 0}, we can follow these steps:

(a) Finding the Maximum and Minimum Values of f on D:

Step 1: Determine the critical points of f within the domain D by finding where the partial derivatives of f with respect to x and y equal zero.

Partial derivative with respect to x:

∂f/∂x = (2x - 1) * e^-(x+y) + (x² + y²) * (-e^-(x+y))

Partial derivative with respect to y:

∂f/∂y = (2y - 1) * e^-(x+y) + (x² + y²) * (-e^-(x+y))

Setting both partial derivatives equal to zero, we get:

(2x - 1) * e^-(x+y) + (x² + y²) * (-e^-(x+y)) = 0   ...(1)

(2y - 1) * e^-(x+y) + (x² + y²) * (-e^-(x+y)) = 0   ...(2)

Step 2: Solve the system of equations (1) and (2) to find the critical points.

From equations (1) and (2), we can observe that the factor e^-(x+y) is common. We can divide both equations by e^-(x+y) and simplify to obtain:

(2x - 1) + (x² + y²) * (-1) = 0   ...(3)

(2y - 1) + (x² + y²) * (-1) = 0   ...(4)

Simplifying equations (3) and (4), we have:

x² + 2x + y² - 1 = 0   ...(5)

x² + y² + 2y - 1 = 0   ...(6)

Step 3: Solve the system of equations (5) and (6) simultaneously to find the critical points.

By subtracting equation (5) from equation (6), we get:

2x - 2y + 2y - 2x = 0

0 = 0

This implies that the equations are dependent, meaning they represent the same line. Therefore, we have infinitely many solutions and no isolated critical points.

Step 4: Check the boundary of the domain D for the maximum and minimum values of f.

On the boundary of D, we have x = 0 or y = 0.

Case 1: x = 0

Substituting x = 0 into f(x, y), we have:

f(0, y) = (0² + y²) * e^-(0+y) = y² * e^-y

Taking the derivative of f(0, y) with respect to y, we get:

df(0, y)/dy = (2y - 1) * e^-y

Setting df(0, y)/dy = 0, we find the critical point:

(2y - 1) * e^-y = 0

2y - 1 = 0

y = 1/2

Case 2: y = 0

Substituting y = 0 into f(x, y), we have:

f(x, 0) = (x² + 0²) * e^-(x+0) = x² * e

The absolute maximum is 8 at x = 3 and the absolute minimum is 3 at x = -2 for the function h(x) = x+5 on the interval -2 ≤ x ≤ 3.

The correct option is, the absolute maximum is 8 at x = 3;

The absolute minimum is 3 at x = -2.

To find the absolute extreme values of the function h(x) = x+5 on the interval -2 ≤ x ≤ 3,

We have to find the highest and lowest points of the graph on that interval.

Find the critical points of the function by setting h'(x) = 0,

h'(x) = 1

Since h'(x) is a constant, there are no critical points.

Therefore, we only have to check the endpoints of the interval.

When x = -2,

h(x) = -2+5 = 3

When x = 3,

h(x) = 3+5 = 8

Therefore,

The absolute minimum of h(x) on the interval is 3, which occurs at x = -2. The absolute maximum of h(x) on the interval is 8, which occurs at x = 3.

Hence, the function h(x) = x+5 has an absolute minimum of 3 at x = -2 and an absolute maximum of 8 at x = 3 on the interval -2 ≤ x ≤ 3.

The sum (f + g)(x) is 4x² - 4 with domain (-∞, ∞), and the difference (f - g)(x) is 2x² + 4 with domain (-∞, ∞).

The sum, difference, product, and quotient of two functions f(x) and g(x) can be found by performing the corresponding operations on their respective values. Given f(x) = 3x² and g(x) = x² - 4, we can determine (f + g)(x), (f - g)(x), (f * g)(x), and (f / g)(x), as well as their domains.

To find (f + g)(x), we add the values of f(x) and g(x) together: (f + g)(x) = f(x) + g(x) = 3x² + (x² - 4) = 4x² - 4.

The domain of (f + g)(x) is the same as the domain of the individual functions f(x) and g(x), which is the set of all real numbers, represented as (-∞, ∞).

To find (f - g)(x), we subtract the values of g(x) from f(x): (f - g)(x) = f(x) - g(x) = 3x² - (x² - 4) = 3x² - x² + 4 = 2x² + 4.

The domain of (f - g)(x) is also the set of all real numbers, (-∞, ∞).

The product (f * g)(x) is obtained by multiplying the values of f(x) and g(x): (f * g)(x) = f(x) * g(x) = (3x²) * (x² - 4) = 3x⁴ - 12x².

The domain of (f * g)(x) remains the same as the domains of f(x) and g(x), which is (-∞, ∞).

Lastly, the quotient (f / g)(x) is calculated by dividing f(x) by g(x): (f / g)(x) = f(x) / g(x) = (3x²) / (x² - 4).

The domain of (f / g)(x) excludes any values of x that make the denominator zero. In this case, x² - 4 = 0 when x = ±2. Therefore, the domain is (-∞, -2) ∪ (-2, 2) ∪ (2, ∞).

In summary, (f + g)(x) = 4x² - 4 with domain (-∞, ∞), (f - g)(x) = 2x² + 4 with domain (-∞, ∞), (f * g)(x) = 3x⁴ - 12x² with domain (-∞, ∞), and (f / g)(x) = (3x²) / (x² - 4) with domain (-∞, -2) ∪ (-2, 2) ∪ (2, ∞).

Given a simple graph with n≥2 vertices satisfying the property that for any two distinct vertices, u, v, Deg(u)+Deg(v) ≥n − 1.To prove that there is a path of length at most 2 between any two vertices.

To prove that there is a path of length at most 2 between any two vertices, we can proceed in the following way:

Let u and v be any two vertices in the graph. Since the graph is connected, there exists a path of length 1 between u and v. This means that u and v are adjacent vertices.

Now, we need to consider two cases:

Case 1: u and v are not connected by an edge.

Let w be any vertex in the graph that is adjacent to u. Since u and v are not connected by an edge, w cannot be equal to v. Therefore, w is a distinct vertex. Now, consider the two vertices v and w.

Since v and w are distinct, we can apply the property of the graph to get:

Deg(v)+Deg(w) ≥ n − 1. Rearranging this inequality, we get:

Deg(v) ≥ n − Deg(w) − 1. Since Deg(u) + Deg(v) ≥ n − 1, we have:

Deg(u) ≥ 1 + Deg(w).

Combining these two inequalities, we get:

Deg(u) + Deg(v) ≥ n − 1 ≥ Deg(w) + Deg(v).

This means that there exists a vertex w that is adjacent to both u and v.

Therefore, there exists a path of length 2 between u and v: u → w → v.

Case 2: u and v are connected by an edge.

In this case, there is a path of length 1 between u and v.

Therefore, there exists a path of length at most 2 between u and v: u → v.

Hence, we have proved that there is a path of length at most 2 between any two vertices in the given graph.

The price that will bring in the greatest revenue is $25,000.

Here's how to solve the problem:

Let R be the revenue made from selling the copies of the film. The total number of copies of the film that the company will sell is given by the expression q - 500000 - 20000p.

The revenue R can be calculated by multiplying the price p of each copy by the total number of copies sold, i.e.,

R(p) = p(q - 500000 - 20000p)

R(p) = pq - 500000p - 20000p²

To find the price that will bring in the greatest revenue, we need to find the value of p that maximizes R(p).

To do this, we can differentiate R(p) with respect to p and set the derivative equal to zero:

dR/dp = q - 500000 - 40000

p = 0

q - 500000 = 40000p

q/40000 - 500000/40000 = p

p = q/40000 - 12.5

Substitute the given value of q = 5500000:

p = 5500000/40000 - 12.5

p = 137.5 - 12.5

p = $25,000

Doripenam is a broad-spectrum antibiotic that is used to treat various bacterial infections. It is important to note that I am an AI language model and cannot provide real-time information on the availability and exact formulation of commercial products.

To make a new suspension of Doripenam, you would typically follow these steps:

1. Select a suitable vehicle: A suspension is a mixture of solid particles in a liquid medium. Therefore, you would need to choose a liquid vehicle that can suspend the drug particles evenly. Commonly used vehicles include water, glycerin, propylene glycol, or a combination of these.

2. Determine the concentration: The concentration of Doripenam in the suspension will depend on the desired therapeutic dose and the solubility of the drug. The solubility can be influenced by factors such as pH, temperature, and the presence of other substances. It may be necessary to conduct solubility studies or consult literature references to determine the optimal concentration.

3. Consider stability: Doripenam is susceptible to degradation in certain conditions. It is important to consider the stability of the drug in the selected vehicle and formulation. Factors such as pH, temperature, and exposure to light can affect the stability. Stability studies, including accelerated stability testing, can be conducted to assess the suitability of the formulation.

4. Select suitable excipients: Excipients are substances added to the formulation to improve stability, enhance palatability, or aid in drug delivery. Commonly used excipients in suspensions include suspending agents (such as hydroxypropyl cellulose or sodium carboxymethylcellulose), preservatives (such as methylparaben or propylparaben), and flavoring agents.

5. Prepare the suspension: The process of preparing the suspension involves accurately weighing or measuring the drug and excipients, followed by mixing them in the appropriate ratios. This can be done using various methods, such as geometric dilution or mechanical mixing. The suspension may need to be homogenized or passed through a sieve to ensure uniform distribution of drug particles.

To identify any unknown properties of the drug you are making, you could perform experiments such as:

1. Solubility studies: Determine the solubility of Doripenam in different solvents or under different pH conditions to assess its compatibility with various vehicles and excipients.

The point P(t) covers a distance of approximately 524.833 units between t=0 and t=7 along the given parametric curve

To find the distance covered by the point P(t) along the parametric curve between t=0 and t=7, we need to calculate the arc length of the curve.

The arc length formula for a parametric curve given by x(t) and y(t) is:

L = ∫[a,b] √((dx/dt)^2 + (dy/dt)^2) dt

In this case, we have x(t) = t^2 + 15t + 6 and y(t) = t^2 + 15t - 13.

First, let's find the derivatives dx/dt and dy/dt:

dx/dt = 2t + 15

dy/dt = 2t + 15

Now, let's calculate the integrand inside the square root:

((dx/dt)^2 + (dy/dt)^2) = (2t + 15)^2 + (2t + 15)^2 = 4(t^2 + 15t + 6)^2

Taking the square root, we have:

√((dx/dt)^2 + (dy/dt)^2) = 2(t^2 + 15t + 6)

Now, we can calculate the integral:

L = ∫[0,7] 2(t^2 + 15t + 6) dt

Integrating with respect to t, we get:

L = [t^3/3 + (15t^2)/2 + 6t] evaluated from t=0 to t=7

L = [(7^3)/3 + (15(7^2))/2 + 6(7)] - [(0^3)/3 + (15(0^2))/2 + 6(0)]

L = (343/3 + 735/2 + 42) - (0 + 0 + 0)

L = 115.333 + 367.5 + 42

L = 524.833 units of distance

a) Elasticity: The elasticity of demand is the ratio of the percentage change in quantity demanded to the percentage change in price.

It tells us the percentage change in quantity demanded resulting from a percentage change in price, and indicates how responsive the quantity demanded is to changes in price. It is given by the equation:
E(p) = (p+2)^2 * 500 / (p+2)^2 * -2
E(p) = -250000/p+2
b) Elasticity at p=9: E(9) = -250000/11 = -22727.27
The demand is inelastic since |E(p)| < 1.
c) Total revenue: Total revenue is given by the equation:
TR(p) = (p+2)^2 * 500
TR(p) = 500p^2 + 2000p + 2000
The derivative of this equation gives us the slope of the curve, which is 0 at the maximum point of the curve. Hence, we have to find the value of p that makes the derivative of TR(p) equal to 0. Differentiating TR(p),

we get:
dTR(p)/dp = 1000p + 2000
1000p + 2000 = 0
p = -2
Since the value of p is negative, the total revenue is maximum at p = $0. Hence, we have to take the value of p as 0 to find the maximum revenue.
TR(0) = 2000.
Thus, the value of p for which the total revenue is maximum is $0 and the maximum revenue is $2000.

Applying the initial condition , the particular solution to the Cauchy problem is: v(t) =  2^(t)

To solve the given Cauchy problem, we can separate variables and then integrate both sides.

The differential equation is:

v'(t) = In 2 * v(t)

Separating variables gives:

(1/v)dv = In 2 * dt

Integrating both sides gives:

∫(1/v) dv = In 2∫dt

The left-hand side integral becomes the natural logarithm of the absolute value of v, and the right-hand side integral is simply t:

ln ∣v∣ = ln2 ⋅ t + C

To determine the constant of integration, we can use the initial condition v(0) = 1. Substituting t = 0 and v = 1 into the equation above, we get:

ln ∣1∣ = ln2⋅0 + C

0=C

So the equation becomes:

ln ∣v∣ = ln 2 ⋅t

Taking the exponential of both sides:

∣v∣ = [tex]e^{In 2t}[/tex]

Since v can be positive or negative, we consider both cases.

For v > 0:

v = 2^(t)

For v < 0:

v = -2^(t)

Therefore, the general solution to the Cauchy problem is:

v(t) = C⋅2t

Applying the initial condition v(0) = 1, we find C = 1. So the particular solution is: v(t) =  v = 2^(t)

(i) When the four points A, B, C and D are non-collinear and joined in pairs, we obtain six line segments. These line segments are AB, AC, AD, BC, BD and CD. A line segment is a part of a line that is bounded by two distinct end points. Therefore, the six line segments obtained have two end points each, one of which coincides with the end point of another line segment.

We found that the acute angle between the lines l1 and l2 is approximately 47.8°. We then showed that the point A lies on the line l1. The lines l1 and l2 intersect at the point X, with coordinates (0, 1, 6). The distance between points A and X was found to be exactly 0. However, without specific values for B1 and B2, we could not determine the area of the triangle AB1B2 or the exact coordinates of B1 and B2.

To solve this problem, we'll go step by step.

(a) Finding the acute angle between l1 and l2:

The direction vectors of lines l1 and l2 are given by the coefficients of the parameters λ and μ. Let's call these direction vectors d1 and d2, respectively.

d1 = [2, -3, 4]

d2 = [5, -2, 5]

To find the acute angle between these two lines, we can use the dot product formula:

cos θ = (d1 · d2) / (|d1| * |d2|)

where · represents the dot product and |d1| and |d2| represent the magnitudes of the vectors d1 and d2, respectively.

Let's calculate this:

d1 · d2 = (2 * 5) + (-3 * -2) + (4 * 5) = 10 + 6 + 20 = 36

[tex]|d1| = \sqrt{(2^2) + (-3^2) + (4^2)} = \sqrt{4 + 9 + 16} = \sqrt{29}[/tex]

[tex]|d2| = \sqrt{(5^2) + (-2^2) + (5^2)} = \sqrt{25 + 4 + 25} = \sqrt{54}[/tex]

cos θ = 36 /( ([tex]\sqrt{29[/tex]) * ([tex]\sqrt{54[/tex])) ≈ 0.675

To find the acute angle θ, we can take the inverse cosine (arccos) of cos θ:

θ ≈ arccos(0.675) ≈ 47.8° (rounded to the nearest 0.1°)

Therefore, the acute angle between l1 and l2 is approximately 47.8°.

(b) Showing that A lies on l1:

To show that a point lies on a line, we substitute the coordinates of the point into the equation of the line and check if it satisfies the equation.

Point A has position vector A = [0, 1, 6]. Substituting these values into the equation of l1:

l1: r = [2, -3, 4] + λ[-1, 2, 1]

Substituting A = [0, 1, 6]:

[0, 1, 6] = [2, -3, 4] + λ[-1, 2, 1]

This equation can be rewritten as a system of equations:

2 - λ = 0

-3 + 2λ = 1

4 + λ = 6

Solving this system, we find:

λ = 2

Since λ = 2 satisfies the system of equations, we conclude that A lies on l1.

(c) Finding the coordinates of X:

To find the point of intersection between l1 and l2, we equate their respective equations:

l1: r = [2, -3, 4] + λ[-1, 2, 1]

l2: r = [2, -3, 4] + μ[5, -2, 5]

Equate the x, y, and z components separately:

For x:

2 - λ = 2 + 5μ

For y:

-3 + 2λ = -3 - 2μ

For z:

4 + λ = 4 + 5μ

Solving this system of equations, we find:

λ = 2

μ = 0

Substituting these values into either equation, we get:

X = [2, -3, 4] + 2[-1, 2

, 1] = [0, 1, 6]

Therefore, the coordinates of the point X are (0, 1, 6).

(d) Finding the exact value of the distance AX:

The distance between two points A and X can be calculated using the distance formula:

Distance [tex]AX = \sqrt{(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2[/tex]

Substituting the coordinates of A = [0, 1, 6] and X = [0, 1, 6]:

Distance [tex]AX = \sqrt{(0 - 0)^2 + (1 - 1)^2 + (6 - 6)^2) }= \sqrt{0 + 0 + 0[/tex] = 0

Therefore, the exact value of the distance AX is 0.

(e) Finding the area of the triangle AB1B2:

To find the area of a triangle given the coordinates of its vertices, we can use the Shoelace formula or the cross product of two vectors formed by the triangle's sides. Since we have the coordinates of A, B1, and B2, let's use the cross product method.

Let's say vector AB1 = v1 and vector AB2 = v2.

Vector v1 = B1 - A = [x1, y1, z1] - [0, 1, 6] = [x1, y1 - 1, z1 - 6]

Vector v2 = B2 - A = [x2, y2, z2] - [0, 1, 6] = [x2, y2 - 1, z2 - 6]

The area of the triangle AB1B2 is given by:

Area = 0.5 * |v1 x v2|

The cross product of v1 and v2 is:

v1 x v2 = [y1 - 1, z1 - 6, x1] x [y2 - 1, z2 - 6, x2]

         = [(z1 - 6)(x2) - (y2 - 1)(x1), (x1)(y2 - 1) - (z1 - 6)(y1 - 1), (y1 - 1)(z2 - 6) - (z1 - 6)(y2 - 1)]

Since AX = XB1 = XB2, the vectors v1 and v2 are parallel. Hence, their cross product will be zero:

[(z1 - 6)(x2) - (y2 - 1)(x1), (x1)(y2 - 1) - (z1 - 6)(y1 - 1), (y1 - 1)(z2 - 6) - (z1 - 6)(y2 - 1)] = [0, 0, 0]

Solving these equations, we get:

(z1 - 6)(x2) - (y2 - 1)(x1) = 0

(x1)(y2 - 1) - (z1 - 6)(y1 - 1) = 0

(y1 - 1)(z2 - 6) - (z1 - 6)(y2 - 1) = 0

Since we don't have specific values for B1 and B2, we cannot determine the area of the triangle AB1B2.

(f) Finding the exact coordinates of B1 and B2:

Without specific values for B1 and B2, we cannot determine their exact coordinates.
