What value of g makes the equation true?

The pharmacy should send two pills marked  for the patient to take.

To answer this question, we can use the formula below;

Dosage = (Amount of Drug x Patient's Weight) / Time

Since we don't have any information about the patient's weight or the time, we can't calculate the dosage.

However, we can calculate the number of pills required.

So, let's proceed with the calculation.

Each pill contains 2.5 mg of the pain reliever.

We need to administer a low dose, so let's assume the dose required is 5 mg.

To administer this dose, we need to give two pills, i.e., 2 x 2.5 = 5mg.

However, the question asks us to round the answer to the nearest tenth of a pill.

Since we can't divide a pill into parts, we need to round the answer up or down to the nearest whole pill.

In this case, since we need two pills, the answer is 2 pills.

Answer:

A

Step-by-step explanation:

Answer:

a) FC ←→ and BD ←→ are distinct lines that intersect.

b) B , C and D are distinct points that are collinear.

c) Another name for plane \(X\) is plane AEF.

d) E , A , F and C are distinct points that are coplanar.  

Step-by-step explanation:

The first step to solve this question is to look carefully at the picture.

For a) :

We can see that the line FC and the line BD intersect at the point C.

We can write :

a) FC ←→ and BD ←→ are distinct lines that intersect (we can see more lines that intersect with FC ←→ in the picture such as AC ←→  or AE ←→).

For b) :

We can see that the line BD ←→ passes through the points B , C and D (B , C and D are collinear points).  

We can write :

b) B , C and D are distinct points that are collinear.

For c) :

We can name any plane using three points which are contain in the plane but this three points must not be collinear points.

We can name the plane \(X\) using the points A , E and F (this is a possible solution).

We can write :

c) Another name for plane \(X\) is plane AEF.

Finally, for d) :

Two or more points are coplanar wherever they belong to the same plane.

In the picture, the points A , E , F and C belong to the plane \(X\).

We can write :

d) E , A , F and C are distinct points that are coplanar.

The total derivative of a function is not necessarily one-to-one. The total derivative represents the change in a function with respect to all of its input variables.

If a function has multiple input variables, the total derivative is a matrix, called the Jacobian matrix, whose entries represent the partial derivatives of the function with respect to each input variable.

A function with a non-invertible Jacobian matrix is not one-to-one, since multiple input values can result in the same output value. For example, consider the function f(x,y) = (x^2, y^2). The total derivative of f is given by the Jacobian matrix:

| 2x 0 |

| 0 2y|

This matrix is non-invertible when x=0 or y=0, since it has a determinant of zero. Thus, the function f is not one-to-one when x=0 or y=0.

In terms of polynomials, the total derivative is important for determining whether a polynomial has multiple roots. A root of a polynomial is a value of the input variable that causes the polynomial to equal zero. If a polynomial has multiple roots, it is not one-to-one, since different input values can result in the same output value.

The total derivative of a polynomial can be computed using the power rule of differentiation. For example, consider the polynomial p(x) = x^3 - 6x^2 + 11x - 6. The total derivative of p with respect to x is:

p'(x) = 3x^2 - 12x + 11

If p'(x) has multiple roots, then p(x) has multiple roots as well. In this case, p'(x) has roots at x=1 and x=11/3, so p(x) has multiple roots at x=1 and x=3. Thus, the total derivative is useful for identifying when a polynomial is not one-to-one.

The mean and the standard deviation of number of cars recovered after being stolen is equal to 760 and 6.16 approximately respectively.

The total number of stolen cars 'n' = 800

The probability of recovering a car 'p' = 0.95

If 800 stolen cars are randomly selected and the probability of recovering a car is 0.95,

Calculate the mean and standard deviation of the number of cars recovered using the formulas for a binomial distribution.

Mean (μ) = np

⇒Mean (μ) = 800 × 0.95

⇒Mean (μ) = 760

Standard Deviation (σ) = √(np(1 - p))

⇒ Standard Deviation (σ) = √(800 × 0.95 × (1 - 0.95))

⇒ Standard Deviation (σ) ≈ √(800 × 0.95 × 0.05)

⇒ Standard Deviation (σ) ≈ √(38)

⇒ Standard Deviation (σ) ≈ 6.16

The solution of the given linear system of equations is x = 2, y = 1 and z = 2.

Given that the linear system of equations is

2x + 4y + 2z = 16-2x - 3y + z = -52x + 2y - 3z = -3

To solve the system of equations by Cramer's rule method, arrange them in the form of Ax = B as below:

A = [2, 4, 2; -2, -3, 1; 2, 2, -3], x = [x, y, z] and B = [16, -5, -3]

To find the inverse of the coefficient matrix A⁻¹, first, find the determinant of A as below:

|A| = 2[-3 - 2] - 4[-2 + 2] + 2[-8 + 1] = -12

The determinant is non-zero, hence A is invertible

A⁻¹ = 1/|A| [adj A]

where adj A is the transpose of the cofactor matrix [C] of A:

adj A = [C]T

So, we find [C] by replacing each element of A with its cofactor and taking its transpose matrix as below:

C = [5, 2, 6; 2, -2, 2; -4, -4, -4]

Then [C]T = [5, 2, -4; 2, -2, -4; 6, 2, -4]So, A⁻¹ = 1/|A| [adj A] = 1/(-12) [5, 2, -4; 2, -2, -4; 6, 2, -4] = [-5/6, -1/2, 1/2; -1/6, 1/2, 1/2; 1/2, 1/2, 1/2]

To solve the system of equations, we have x = A⁻¹B as below:

x = [-5/6, -1/2, 1/2; -1/6, 1/2, 1/2; 1/2, 1/2, 1/2][16; -5; -3] = [2; 1; 2]

Therefore, the area between the large loop and the small loop of the curve r = 2 + 4cos(3θ) is 70π/3.

To find the area between the large loop and the small loop of the curve, we need to find the points of intersection of the curve with itself.

Setting the equation of the curve equal to itself, we have:

2 + 4cos(3θ) = 2 + 4cos(3(θ + π))

Simplifying and solving for θ, we get:

cos(3θ) = -cos(3θ + 3π)

cos(3θ) + cos(3θ + 3π) = 0

Using the sum to product formula, we get:

2cos(3θ + 3π/2)cos(3π/2) = 0

cos(3θ + 3π/2) = 0

3θ + 3π/2 = π/2, 3π/2, 5π/2, 7π/2, ...

Solving for θ, we get:

θ = -π/6, -π/18, π/6, π/2, 5π/6, 7π/6, 3π/2, 11π/6

We can see that there are two small loops between θ = -π/6 and π/6, and two large loops between θ = π/6 and π/2, and between θ = 5π/6 and 7π/6.

To find the area between the large loop and the small loop, we need to integrate the area between the curve and the x-axis from θ = -π/6 to π/6, and subtract the area between the curve and the x-axis from θ = π/6 to π/2, and from θ = 5π/6 to 7π/6.

Using the formula for the area enclosed by a polar curve, we have:

A = 1/2 ∫[a,b] (r(θ))^2 dθ

where a and b are the angles of intersection.

For the small loops, we have:

A1 = 1/2 ∫[-π/6,π/6] (2 + 4cos(3θ))^2 dθ

Using trigonometric identities, we can simplify this to:

A1 = 1/2 ∫[-π/6,π/6] 20 + 16cos(6θ) + 8cos(3θ) dθ

Evaluating the integral, we get:

A1 = 10π/3

For the large loops, we have:

A2 = 1/2 (∫[π/6,π/2] (2 + 4cos(3θ))^2 dθ + ∫[5π/6,7π/6] (2 + 4cos(3θ))^2 dθ)

Using the same trigonometric identities, we can simplify this to:

A2 = 1/2 (∫[π/6,π/2] 20 + 16cos(6θ) + 8cos(3θ) dθ + ∫[5π/6,7π/6] 20 + 16cos(6θ) + 8cos(3θ) dθ)

Evaluating the integrals, we get:

A2 = 80π/3

Therefore, the area between the large loop and the small loop of the curve r = 2 + 4cos(3θ) is:

A = A2 - A1 = (80π/3) - (10π/3) = 70π/3

x = 37 - y

and we know that with this unknown mixture they scored 80 points.

so,

112.5 = k × 15² = 225k ( divide both sides by 225 )

0.5 = k

d = 0.5v² ← equation of variation

The derivative of the function P(x) = 7x - ln(7x) is P'(x) = 7 - (1/x).

To evaluate the derivative of the function P(x) = 7x - ln(7x), we need to apply the rules of differentiation.

The derivative of a function represents the rate at which the function is changing with respect to its independent variable.

For the given function, we can differentiate each term separately using the rules of differentiation:

The derivative of 7x with respect to x is simply 7, since the derivative of a constant times x is the constant itself.

The derivative of ln(7x) with respect to x involves the chain rule.

The chain rule states that if we have a composite function, such as ln(g(x)), then its derivative is given by (1/g(x)) \(\times\) g'(x).

Applying the chain rule to the second term, we have:

d/dx [ln(7x)] = (1/(7x)) \(\times\) d/dx [7x]

Since the derivative of 7x is 7, we can simplify this further:

d/dx [ln(7x)] = (1/(7x)) \(\times\) 7 = 1/x

Now, adding up the derivatives of the individual terms, we have:

P'(x) = 7 - (1/x)

The rate of increase in population size will depend on the magnitude of the difference between the birth and death rates, as well as the extent of emigration and immigration.

If the number of births in a population are greater than the number of deaths and the emigration rate is 2x the immigration rate, then the population size is likely to increase over time. This is because there are more individuals being born than dying, and even though there is a higher emigration rate, the net effect is still an increase in population size. However, the rate of increase in population size will depend on the magnitude of the difference between the birth and death rates, as well as the extent of emigration and immigration.
If the number of births in a population is greater than the number of deaths, and the emigration rate is 2x the immigration rate, the population size is likely to experience some growth due to the excess of births over deaths. However, the growth may be slowed down or even potentially decrease over time, as the higher emigration rate could lead to more people leaving the population than entering it.

Given that the line that passes through the points (-4,8) and (4,4).

To find the slope of the line that passes through points (-4,8) and (4,4).

Therefore, the slope of the line is;

m = Δy/Δx

m = (4 - 8)/(4 + 4)

m = -4/8

When we simplify it, then we get the;

m = -1/2

The point-slope equation will be;

y−4= −1/2 (x−4)
