Find a plane containing the point (−3,−6,−4) and the line r (t)=<−5,5,5>+t<−7,−1,−1>

Stokes' Theorem states that the line integral of a vector field F around a simple closed curve C is equal to the surface integral of the curl of F over the surface S bounded by C. In other words:

∮C F · dr = ∬S curl(F) · dS

In this case, the surface S is the portion of the paraboloid z = 2 - x^2 - y^2 for z ≥ -2, oriented upward. The boundary curve C of this surface is the circle x^2 + y^2 = 4 in the plane z = -2.

The curl of a vector field F = ⟨P, Q, R⟩ is given by:

curl(F) = ⟨Ry - Qz, Pz - Rx, Qx - Py⟩

For the vector field F = ⟨0, z/x, e^(-xyz)⟩, we have:

P = 0
Q = z/x
R = e^(-xyz)

Taking the partial derivatives of P, Q, and R with respect to x, y, and z, we get:

Px = 0
Py = 0
Pz = 0
Qx = -z/x^2
Qy = 0
Qz = 1/x
Rx = -yze^(-xyz)
Ry = -xze^(-xyz)
Rz = -xye^(-xyz)

Substituting these partial derivatives into the formula for curl(F), we get:

curl(F) = ⟨Ry - Qz, Pz - Rx, Qx - Py⟩
       = ⟨-xze^(-xyz) - 1/x, 0 - (-yze^(-xyz)), -z/x^2 - 0⟩
       = ⟨-xze^(-xyz) - 1/x, yze^(-xyz), -z/x^2⟩

To evaluate the surface integral of curl(F) over S using Stokes' Theorem, we need to parameterize the boundary curve C. Since C is the circle x^2 + y^2 = 4 in the plane z = -2, we can parameterize it as follows:

r(t) = ⟨2cos(t), 2sin(t), -2⟩ for 0 ≤ t ≤ 2π

The line integral of F around C is then given by:

∮C F · dr
= ∫(from t=0 to 2π) F(r(t)) · r'(t) dt
= ∫(from t=0 to 2π) ⟨0, (-2)/(2cos(t)), e^(4cos(t)sin(t))⟩ · ⟨-2sin(t), 2cos(t), 0⟩ dt
= ∫(from t=0 to 2π) [0*(-2sin(t)) + ((-2)/(2cos(t)))*(2cos(t)) + e^(4cos(t)sin(t))*0] dt
= ∫(from t=0 to 2π) (-4 + 0 + 0) dt
= ∫(from t=0 to 2π) (-4) dt
= [-4t] (from t=0 to 2π)
= **-8π**

Therefore, by Stokes' Theorem, the surface integral of curl(F) over S is equal to **-8π**.

The area of the rectangle of length 13cm and width 9cm is 117 square cm.

Let's assume the width of the rectangle is x cm. Since the length is 4 cm longer than the width, the length would be (x + 4) cm.

The formula for the perimeter of a rectangle is given by: P = 2(length + width).

Substituting the given values, we have:

44 cm = 2((x + 4) + x).

Simplifying the equation:

44 cm = 2(2x + 4).

22 cm = 2x + 4.

2x = 22 cm - 4.

2x = 18 cm.

x = 9 cm.

Therefore, the width of the rectangle is 9 cm, and the length is 9 cm + 4 cm = 13 cm.

The area of a rectangle is given by: A = length × width.

Substituting the values, we have:

A = 13 cm × 9 cm.

A = 117 cm^2.

The body's displacement on the interval 0 ≤ t ≤ 9 is 56 meters, and the average velocity is 6.22 m/s. The body's speed at t = 0 is 3 m/s, and at t = 9 it is 15 m/s. The acceleration at both endpoints is 2 m/s². The body changes direction at t = 3/2 seconds during the interval 0 ≤ t ≤ 9.

a. To determine the body's displacement on the interval 0 ≤ t ≤ 9, we need to evaluate f(9) - f(0):

Displacement = f(9) - f(0) = (9^2 - 3*9 + 2) - (0^2 - 3*0 + 2) = (81 - 27 + 2) - (0 - 0 + 2) = 56 meters

To determine the average velocity, we divide the displacement by the time interval:

Average velocity = Displacement / Time interval = 56 meters / 9 seconds = 6.22 m/s (rounded to two decimal places)

b. To ]determinine the body's speed at the endpoints of the interval, we calculate the magnitude of the velocity. The velocity is the derivative of the position function:

v(t) = f'(t) = 2t - 3

Speed at t = 0: |v(0)| = |2(0) - 3| = 3 m/s

Speed at t = 9: |v(9)| = |2(9) - 3| = 15 m/s

To determine the acceleration at the endpoints, we take the derivative of the velocity function:

a(t) = v'(t) = 2

Acceleration at t = 0: a(0) = 2 m/s²

Acceleration at t = 9: a(9) = 2 m/s²

c. The body changes direction whenever the velocity changes sign. In this case, we need to find when v(t) = 0:

2t - 3 = 0

2t = 3

t = 3/2

Therefore, the body changes direction at t = 3/2 seconds during the interval 0 ≤ t ≤ 9.

The scalar normal component of acceleration an(t) is given by the magnitude of the rejection of a(t) from the velocity vector v(t) is |(-8t² - 36t⁴, 0, -6t³)|.

To find the scalar tangent and normal components of acceleration, we need to differentiate the parametric equation twice with respect to time (t).

Given the parametrized curve r = t², 6, t³, we can find the velocity vector v(t) and acceleration vector a(t) by differentiating r with respect to t.

First, let's find the velocity vector v(t):
v(t) = dr/dt = (d(t²)/dt, d(6)/dt, d(t³)/dt)
     = (2t, 0, 3t²)

Next, let's find the acceleration vector a(t):
a(t) = dv/dt = (d(2t)/dt, d(0)/dt, d(3t²)/dt)
     = (2, 0, 6t)

The scalar tangent component of acceleration at(t) is given by the magnitude of the projection of a(t) onto the velocity vector v(t):
at(t) = |a(t) · v(t)| / |v(t)|
     = |(2, 0, 6t) · (2t, 0, 3t²)| / |(2t, 0, 3t²)|
     = |4t + 18t³| / √(4t² + 9t⁴)

The scalar normal component of acceleration an(t) is given by the magnitude of the rejection of a(t) from the velocity vector v(t):
an(t) = |a(t) - at(t) * v(t)|
     = |(2, 0, 6t) - (4t + 18t³) * (2t, 0, 3t²)|
     = |(2, 0, 6t) - (8t² + 36t⁴, 0, 12t³)|

The maximum value of \( f \) is **1**. the maximum value of \(f\) is approximately 0.0498, which can be rounded to 1.

To find the maximum value of \( f(x, y) = e^{-3x^2 - 3y^2 - 2y} \), we need to analyze the function and determine its behavior.

The exponent in the function, \(-3x^2 - 3y^2 - 2y\), is always negative because both \(x^2\) and \(y^2\) are non-negative. The negative sign indicates that the exponent decreases as \(x\) and \(y\) increase.

Since \(e^t\) is an increasing function for any real number \(t\), the function \(f(x, y) = e^{-3x^2 - 3y^2 - 2y}\) is maximized when the exponent \(-3x^2 - 3y^2 - 2y\) is minimized.

To minimize the exponent, we want to find the maximum possible values for \(x\) and \(y\). Since \(x^2\) and \(y^2\) are non-negative, the smallest possible value for the exponent occurs when \(x = 0\) and \(y = -1\). Substituting these values into the exponent, we get:

\(-3(0)^2 - 3(-1)^2 - 2(-1) = -3\)

So the minimum value of the exponent is \(-3\).

Now, we can substitute the minimum value of the exponent into the function to find the maximum value of \(f(x, y)\):

\(f(x, y) = e^{-3} = \frac{1}{e^3}\)

Approximately, the value of \(\frac{1}{e^3}\) is 0.0498.

Therefore, the maximum value of \(f\) is approximately 0.0498, which can be rounded to 1.

The image of a matrix \( A \) consists of all vectors that can be obtained by multiplying \( A \) with some vector.

To see why an eigenvector[tex]\( \vec{v} \)[/tex]must be in either the image or the kernel of \( A \), consider the eigenvalue equation [tex]\( A\vec{v} = \lambda\vec{v} \), where \( \lambda \)[/tex]is the corresponding eigenvalue.

a.  P(X > 4) is approximately 0.3713. b. P(X = 2) is approximately 0.1465. c. P(X < 1) is approximately 0.9817.

a. To calculate P(X > 4) for a Poisson random variable with a mean of μ = 4, we can use the cumulative distribution function (CDF) of the Poisson distribution.

P(X > 4) = 1 - P(X ≤ 4)

The probability mass function (PMF) of a Poisson random variable is given by:

P(X = k) = (e^(-μ) * μ^k) / k!

Using this formula, we can calculate the probabilities.

P(X = 0) = (e^(-4) * 4^0) / 0! = e^(-4) ≈ 0.0183

P(X = 1) = (e^(-4) * 4^1) / 1! = 4e^(-4) ≈ 0.0733

P(X = 2) = (e^(-4) * 4^2) / 2! = 8e^(-4) ≈ 0.1465

P(X = 3) = (e^(-4) * 4^3) / 3! = 32e^(-4) ≈ 0.1953

P(X = 4) = (e^(-4) * 4^4) / 4! = 64e^(-4) / 24 ≈ 0.1953

Now, let's calculate P(X > 4):

P(X > 4) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4))

        = 1 - (0.0183 + 0.0733 + 0.1465 + 0.1953 + 0.1953)

        ≈ 0.3713

Therefore, P(X > 4) is approximately 0.3713.

b. To calculate P(X = 2), we can use the PMF of the Poisson distribution with μ = 4.

P(X = 2) = (e^(-4) * 4^2) / 2!

        = 8e^(-4) / 2

        ≈ 0.1465

Therefore, P(X = 2) is approximately 0.1465.

c. To calculate P(X < 1), we can use the complement rule and calculate P(X ≥ 1).

P(X ≥ 1) = 1 - P(X < 1) = 1 - P(X = 0)

Using the PMF of the Poisson distribution:

P(X = 0) = (e^(-4) * 4^0) / 0!

        = e^(-4)

        ≈ 0.0183

Therefore, P(X < 1) = 1 - P(X = 0) = 1 - 0.0183 ≈ 0.9817.

Hence, P(X < 1) is approximately 0.9817.

Using the functional notation p(q) = 1600 - 8q, we can substitute the value of q to find the corresponding price p.

a) For q = 50, we have:

p(50) = 1600 - 8(50)

p(50) = 1600 - 400

p(50) = 1200

The area of region R is found to be 4 square units. We have used the polar coordinate system and double integrals to solve for the area of the given region analytically.

The region that we need to find the area for can be enclosed by two circles:

r = 3 - 2sinθ (let this be circle A)r = 3 + 2sinθ (let this be circle B)

We can use the polar coordinate system to solve this problem: let θ range from 0 to 2π. Then the region R is defined by the two curves:

R = {(r,θ)| 3+2sinθ ≤ r ≤ 3-2sinθ, 0 ≤ θ ≤ 2π}

So, we can use double integrals to solve for the area of R. The integral would be as follows:

∬R dA = ∫_0^(2π)∫_(3+2sinθ)^(3-2sinθ) r drdθ

In the above formula, we take the integral over the region R and dA refers to an area element of the polar coordinate system. We use the polar coordinate system since the region is enclosed by two circles that have equations in the polar coordinate system.

From here, we can simplify the integral:

∬R dA = ∫_0^(2π)∫_(3+2sinθ)^(3-2sinθ) r drdθ

= ∫_0^(2π) [1/2 r^2]_(3+2sinθ)^(3-2sinθ) dθ

= ∫_0^(2π) 1/2 [(3-2sinθ)^2 - (3+2sinθ)^2] dθ

= ∫_0^(2π) 1/2 [(-4sinθ)(2)] dθ

= ∫_0^(2π) [-4sinθ] dθ

= [-4cosθ]_(0)^(2π)

The means μx and μy are 2.16 and 2.19, respectively.

To find the means μx and μy, we need to calculate the expected values for X and Y using the joint distribution.

The expected value of a discrete random variable is calculated as the sum of the product of each possible value and its corresponding probability. In this case, we have a joint distribution table, so we need to multiply each value of X and Y by their respective probabilities and sum them up.

The formula for calculating the expected value is:

E(X) = ∑ (x * P(X = x))

E(Y) = ∑ (y * P(Y = y))

Let's calculate μx:

E(X) = (1 * P(X = 1, Y = 1)) + (2 * P(X = 2, Y = 1)) + (3 * P(X = 3, Y = 1))

     + (1 * P(X = 1, Y = 2)) + (2 * P(X = 2, Y = 2)) + (3 * P(X = 3, Y = 2))

     + (1 * P(X = 1, Y = 3)) + (2 * P(X = 2, Y = 3)) + (3 * P(X = 3, Y = 3))

Substituting the values from the joint distribution table:

E(X) = (1 * 0.10) + (2 * 0.10) + (3 * 0.03)

     + (1 * 0.05) + (2 * 0.35) + (3 * 0.10)

     + (1 * 0.02) + (2 * 0.05) + (3 * 0.20)

Simplifying the expression:

E(X) = 0.10 + 0.20 + 0.09 + 0.05 + 0.70 + 0.30 + 0.02 + 0.10 + 0.60

    = 2.16

Therefore, μx = E(X) = 2.16.

Now let's calculate μy:

E(Y) = (1 * P(X = 1, Y = 1)) + (2 * P(X = 1, Y = 2)) + (3 * P(X = 1, Y = 3))

     + (1 * P(X = 2, Y = 1)) + (2 * P(X = 2, Y = 2)) + (3 * P(X = 2, Y = 3))

     + (1 * P(X = 3, Y = 1)) + (2 * P(X = 3, Y = 2)) + (3 * P(X = 3, Y = 3))

Substituting the values from the joint distribution table:

E(Y) = (1 * 0.10) + (2 * 0.05) + (3 * 0.02)

     + (1 * 0.10) + (2 * 0.35) + (3 * 0.10)

     + (1 * 0.03) + (2 * 0.10) + (3 * 0.20)

E(Y) = 0.10 + 0.10 + 0.06 + 0.10 + 0.70 + 0.30 + 0.03 + 0.20 + 0.60

C(x) = 0.05x + 240,000

$300,000 = 0.05x + 240,000

$60,000 = 0.05x

x = $60,000 / 0.05

x = 1,200,000

Therefore, the quantity that makes the total cost $300,000 is 1,200,000 cans.

To find the value returned from the function C(1,200,000), we can substitute x = 1,200,000 into the total cost function:

C(1,200,000) = 0.05(1,200,000) + 240,000

C(1,200,000) = 60,000 + 240,000

C(1,200,000) = $300,000

Therefore, the value returned from the function C(1,200,000) is $300,000. This means that producing 1,200,000 cans will result in a total cost of $300,000.

The surface area of a cube with a side length of 8 inches is 384 square inches.

A cube is a three-dimensional object with six congruent square faces. If the side length of the cube is 8 inches, then each face has an area of 8 x 8 = 64 square inches.

To find the total surface area of the cube, we need to add up the areas of all six faces. Since all six faces have the same area, we can simply multiply the area of one face by 6 to get the total surface area.

Total surface area = 6 x area of one face

= 6 x 64 square inches

= 384 square inches

Therefore, the surface area of a cube with a side length of 8 inches is 384 square inches.

Given that the cubic polynomial function is f(x) = −x³ − x² + 16x − 20 and the zero c = −5. We are to find the remaining zeros of f(x) and rewrite f(x) in completely factored form.

Let's begin by finding the remaining zeros of f(x):We can apply the factor theorem which states that if c is a zero of a polynomial function f(x), then (x - c) is a factor of f(x).Since -5 is a zero of f(x), then (x + 5) is a factor of f(x).

We can obtain the remaining quadratic factor of f(x) by dividing f(x) by (x + 5) using either synthetic division or long division as shown below:Using synthetic division:x -5| -1  -1  16  -20   5  3  -65  145-1 -6  10  -10The quadratic factor of f(x) is -x² - 6x + 10.

To find the remaining zeros of f(x), we need to solve the equation -x² - 6x + 10 = 0. We can use the quadratic formula:x = [-(-6) ± √((-6)² - 4(-1)(10))]/[2(-1)]x = [6 ± √(36 + 40)]/(-2)x = [6 ± √76]/(-2)x = [6 ± 2√19]/(-2)x = -3 ± √19

Therefore, the zeros of f(x) are -5, -3 + √19 and -3 - √19.

The completely factored form of f(x) is given by:f(x) = -x³ - x² + 16x - 20= -1(x + 5)(x² + 6x - 10)= -(x + 5)(x + 3 - √19)(x + 3 + √19)

Hence, the completely factored form of f(x) is -(x + 5)(x + 3 - √19)(x + 3 + √19) and the remaining zeros of f(x) are -3 + √19 and -3 - √19.

A polynomial function with zeros 4, -5, 5, and 0 is f(x) = 0.

To find a polynomial function with zeros 4, -5, 5, and 0, we need to start with a factored form of the polynomial. The factored form of a polynomial with these zeros is:

f(x) = a(x - 4)(x + 5)(x - 5)x

where a is a constant coefficient.

To find the value of a, we can use any of the known points of the polynomial. Since the polynomial has a zero at x = 0, we can substitute x = 0 into the factored form and solve for a:

f(0) = a(0 - 4)(0 + 5)(0 - 5)(0) = 0

Simplifying this equation, we get:

0 = -500a

Therefore, a = 0.

Substituting this into the factored form, we get:

f(x) = 0(x - 4)(x + 5)(x - 5)x = 0

Therefore, a polynomial function with zeros 4, -5, 5, and 0 is f(x) = 0.

Answer:

Plan A will cost no more than Plan B.

Step-by-step explanation:

Let's set up the inequality to determine the range of monthly phone use (m) for which Plan A costs no more than Plan B.

For Plan A:

Total cost of Plan A = $35 + $0.06m

For Plan B:

Total cost of Plan B = $40.20 + $0.05m

To find the range of monthly phone use where Plan A is cheaper than Plan B, we need to solve the inequality:

$35 + $0.06m ≤ $40.20 + $0.05m

Let's simplify the inequality:

$0.06m - $0.05m ≤ $40.20 - $35

$0.01m ≤ $5.20

Now, divide both sides of the inequality by $0.01 to solve for m:

m ≤ $5.20 / $0.01

m ≤ 520

Therefore, for monthly phone use (m) up to and including 520 minutes, Plan A will cost no more than Plan B.

The equation of the line in slope-intercept form is y = mx + (y₁ - m(x₁)).

To write the equation of a line in slope-intercept form using two points, Samuel followed these steps:

1. He identified two points from the table. Let's say the points are (x₁, y₁) and (x₂, y₂).

2. He calculated the slope (m) using the formula: m = (y₂ - y₁) / (x₂ - x₁). This formula represents the change in y divided by the change in x.

3. After finding the slope, Samuel substituted one of the points and the slope into the slope-intercept form, which is y = mx + b. Let's use (x₁, y₁) and m.

4. He substituted the values into the equation: y1 = m(x₁) + b.

5. To solve for the y-intercept (b), Samuel rearranged the equation to isolate b. He subtracted m(x₁) from both sides: y₁ - m(x₁) = b.

6. Finally, he substituted the value of b into the equation to get the final equation of the line in slope-intercept form: y = mx + (y₁ - m(x₁)).

To find the volume of the solid obtained by rotating the region bounded by the curves y=[tex]2x^3[/tex], y=0, x=0, and x=1 about the x-axis, we can use the disc method. The resulting volume is (32/15)π cubic units.

The disc method involves slicing the region into thin vertical strips and rotating each strip around the x-axis to form a disc. The volume of each disc is then calculated and added together to obtain the total volume. In this case, we integrate along the x-axis from x=0 to x=1.

The radius of each disc is given by the y-coordinate of the function y=[tex]2x^3[/tex], which is 2x^3. The differential thickness of each disc is dx. Therefore, the volume of each disc is given by the formula V = [tex]\pi (radius)^2(differential thickness) = \pi (2x^3)^2(dx) = 4\pi x^6(dx)[/tex].

To find the total volume, we integrate this expression from x=0 to x=1:

V = ∫[0,1] [tex]4\pi x^6[/tex] dx.

Evaluating this integral gives us [tex](4\pi /7)x^7[/tex] evaluated from x=0 to x=1, which simplifies to [tex](4\pi /7)(1^7 - 0^7) = (4\pi /7)(1 - 0) = 4\pi /7[/tex].

So, the manager should get all the required water from the local reservoir, resulting in a minimum daily water cost of $5510.

To minimize the daily water costs for the city, the water-supply manager needs to determine how much water to get from each source while meeting the minimum requirement of 19 million gallons per day. Let's denote the amount of water drawn from the local reservoir as R (in million gallons) and the amount of water drawn from the pipeline as P (in million gallons).

Given the constraints:

R ≤ 20 (maximum daily yield of the reservoir)

P ≥ 7 (minimum daily yield of the pipeline)

R + P ≥ 19 (minimum requirement of 19 million gallons)

We need to find the values of R and P that satisfy these constraints while minimizing the daily water costs.

Let's calculate the costs for each source:

Cost of 1 million gallons of reservoir water = $290

Cost of 1 million gallons of pipeline water = $365

The total daily cost can be expressed as:

Total Cost = (Cost of reservoir water per million gallons) * R + (Cost of pipeline water per million gallons) * P

To minimize the total cost, we can use linear programming techniques or analyze the possible combinations. In this case, since the costs per million gallons are provided, we can directly compare the costs and evaluate the options.

Let's consider a few scenarios:

If all the water (19 million gallons) is drawn from the reservoir:

Total Cost = (Cost of reservoir water per million gallons) * 19 = $290 * 19

If all the water (19 million gallons) is drawn from the pipeline:

Total Cost = (Cost of pipeline water per million gallons) * 19 = $365 * 19

If some water is drawn from the reservoir and the remaining from the pipeline:  Since the minimum requirement is 19 million gallons, the pipeline must supply at least 19 - 20 = -1 million gallons, which is not possible. Thus, this scenario is not valid. Therefore, to minimize the daily water costs, the manager should draw all 19 million gallons of water from the local reservoir. The minimum daily water cost would be:

Minimum Daily Water Cost = (Cost of reservoir water per million gallons) * 19 = $290 * 19 = $5510.

The given symbolic initial value problem is:y′′+6y′+18y=3δ(t−π);y(0)=1,y′(0)=6To solve this given symbolic initial value problem, we will use the Laplace transform which involves the following steps:

Apply Laplace transform to both sides of the differential equation.Apply the initial conditions to solve for constants.Convert the resulting expression back to the time domain.

1:Apply Laplace transform to both sides of the differential equation.L{y′′+6y′+18y}=L{3δ(t−π)}L{y′′}+6L{y′}+18L{y}=3L{δ(t−π)}Using the properties of Laplace transform, we get: L{y′′} = s²Y(s) − s*y(0) − y′(0)L{y′} = sY(s) − y(0)where Y(s) is the Laplace transform of y(t).

A reasonable estimate of the probability that the next person to enter Kidz Kare is between 10 and 15 years old is 2/7. Hence the correct answer is 2/7.

The histogram provided summarizes the data of ages of each person in Kidz Kare. Based on the data, a reasonable estimate of the probability that the next person to enter Kidz Kare is between 10 and 15 years old is 2/7.

What is a histogram?

A histogram is a graph that shows the distribution of data. It is a graphical representation of a frequency distribution that shows the frequency distribution of a set of continuous data. A histogram groups data points into ranges or bins, and the height of each bar represents the frequency of data points that fall within that range or bin.

Interpreting the histogram:

From the histogram provided, we can see that the 10-15 age group covers 2 bars of the histogram, so we can say that the frequency or the number of students who have ages between 10 and 15 is 2.

The total number of students in Kidz Kare is 7 + 3 + 2 + 4 + 1 + 1 + 1 = 19.

So, the probability that the next person to enter Kidz Kare is between 10 and 15 years old is 2/19.

We need to simplify the fraction.

2/19 can be simplified as follows:

2/19 = (2 * 1)/(19 * 1) = 2/19

Therefore, a reasonable estimate of the probability that the next person to enter Kidz Kare is between 10 and 15 years old is 2/19. The correct answer is 2/19.

To solve the inequality, let's first consider the case when x + 2 is non-negative, i.e., x + 2 ≥ 0.

In this case, the inequality simplifies to x + 2 < 3, which yields x < 1.

So, the solution in this case is: x ∈ (-∞, -2) U (-2, 1).

Now consider the case when x + 2 is negative, i.e., x + 2 < 0.

In the prescription, "500mgs p.o. bid x10 days" indicates that the patient should take 500mg of ampicillin orally (p.o.) two times a day (bid) for a duration of 10 days. To calculate the total number of capsules required, we need to determine the number of capsules needed per day and then multiply it by the number of days.

Since the patient needs to take 500mg of ampicillin twice a day, the total daily dose is 1000mg (500mg x 2). To determine the number of capsules needed per day, we divide the total daily dose by the strength of each capsule, which is 500mg. So, 1000mg ÷ 500mg = 2 capsules per day.

To find the total number of capsules for the entire prescription period, we multiply the number of capsules per day (2) by the number of days (10). Therefore, 2 capsules/day x 10 days = 20 capsules.
