(a) The critical number of f(x) is x = 3.

(b) The function is increasing on the interval (-∞, 3) and decreasing on the interval (3, ∞).

(c) The function has a relative minimum at the point (3, -7).

(a) To find the critical numbers of the function, we need to find its derivative and set it equal to zero. Given the function f(x) = -4x^2 + 24x + 5, let's find its derivative:

f'(x) = -8x + 24.

Setting f'(x) equal to zero and solving for x, we get:

-8x + 24 = 0 => x = 3.

Therefore, the critical number of the function is x = 3.

(b) To determine the intervals on which the function is increasing or decreasing, we need to analyze the sign of the derivative f'(x) to the left and right of the critical number x = 3. Let's test the intervals:

For x < 3:

f'(x) > 0 (positive).

For x > 3:

f'(x) < 0 (negative).

Therefore, the function is increasing on the interval (-∞, 3) and decreasing on the interval (3, ∞).

(c) To identify the relative extrema, we can apply the First Derivative Test. Since the function is increasing on (-∞, 3) and decreasing on (3, ∞), we can conclude that there is a relative minimum at x = 3.

Evaluating the function at this critical number, we have:

f(3) = -4(3)^2 + 24(3) + 5 = -7.

Hence, the relative minimum is located at the point (3, -7).

(a) Therefore, the vector projection p of x onto y is the zero vector [0, 0, 0]. (b) Since the dot product is zero, we can conclude that x-p is orthogonal to p. (c) Therefore, [tex]||x||^2 = ||p||^2 + ||x-p||^2[/tex]holds, verifying the Pythagorean Law for x, p, and x-p.

(a) To find the vector projection p of x onto y, we can use the formula: p = [tex](x · y / ||y||^2) * y[/tex], where · represents the dot product and ||y|| represents the norm (magnitude) of y.

First, calculate the dot product of x and y: x · y = (-1 * 1) + (0 * 1) + (1 * 1) = 0.

Next, calculate the norm squared of [tex]y: ||y||^2 = (1^2) + (1^2) + (1^2) = 3.[/tex]

Now, substitute these values into the formula: p = (0 / 3) * [1, 1, 1] = [0, 0, 0].

Therefore, the vector projection p of x onto y is the zero vector [0, 0, 0].

(b) To verify that x-p is orthogonal to p, we need to check if their dot product is zero. Calculating the dot product: (x - p) · p = ([-1, 0, 1] - [0, 0, 0]) · [0, 0, 0] = [-1, 0, 1] · [0, 0, 0] = 0.

Since the dot product is zero, we can conclude that x-p is orthogonal to p.

(c) To verify the Pythagorean Law, we need to check if ||x||^2 = ||p||^2 + ||x-p||^2.

Calculating the norms:

[tex]||x||^2 = (-1)^2 + 0^2 + 1^2 = 2,[/tex]

[tex]||p||^2 = 0^2 + 0^2 + 0^2 = 0,[/tex]

[tex]||x-p||^2 = (-1)^2 + 0^2 + 1^2 = 2.[/tex]

Therefore, [tex]||x||^2 = ||p||^2 + ||x-p||^2[/tex] holds, verifying the Pythagorean Law for x, p, and x-p.

In summary, the vector projection p of x onto y is the zero vector [0, 0, 0]. The vectors x-p and p are orthogonal, as their dot product is zero. Additionally, the Pythagorean Law is satisfied, with the norm of x equal to the sum of the norms of p and x-p.

The value of "a" in the expression (2.2 x 10³) + (6.25 x 10⁻²) = ax 10ᵧ is 2.20625.

In scientific notation, numbers are expressed as a product of a coefficient and a power of 10. To find the value of "a" in the given expression, we need to add the coefficients and multiply the powers of 10.

In the first term, 2.2 x 10³, the coefficient is 2.2 and the power of 10 is 3. In the second term, 6.25 x 10⁻², the coefficient is 6.25 and the power of 10 is -2.

To add the coefficients, we simply perform the addition: 2.2 + 6.25 = 8.45.

To multiply the powers of 10, we add the exponents: 10³ + (-2) = 10¹.

Therefore, the value of "a" is 8.45 x 10¹, which can be written as 8.45 x 10 or 8.45.

Answer:

C

Step-by-step explanation: no

(a)a + b = (13, 0) + (7√3/2, 7/2) = (13 + 7√3/2, 7/2) = (13 + 3.5√3, 3.5)

(b)the direction of a + b relative to a is 60°.

(c)Therefore, a · b = 91√3/2.

(a) To find the vector sum a + b, we need to determine the components of vectors a and b. Since vector a is horizontal, its components are a = (13, 0) (assuming a is directed along the positive x-axis). Vector b is 60° above vector a, which means it forms a 30° angle with the positive x-axis. The magnitude of vector b is given as |b| = 7.

Using trigonometric relations, we can determine the components of vector b:

b_x = |b| * cos(30°) = 7 * cos(30°) = 7 * (√3/2) = 7√3/2

b_y = |b| * sin(30°) = 7 * sin(30°) = 7 * (1/2) = 7/2

Now we can calculate the vector sum:

a + b = (13, 0) + (7√3/2, 7/2) = (13 + 7√3/2, 7/2) = (13 + 3.5√3, 3.5)

(b) The direction of the vector sum a + b relative to vector a can be determined by finding the angle it forms with the positive x-axis. Since vector a is horizontal, its angle with the x-axis is 0°. Vector b is 60° above vector a, so the angle it forms with the x-axis is 60°.

Therefore, the direction of a + b relative to a is 60°.

(c) To find the dot product of vectors a and b (a · b), we need to know their components. The components of vector a are (13, 0), and the components of vector b are (b_x, b_y) = (7√3/2, 7/2).

The dot product can be calculated as follows:

a · b = (13, 0) · (7√3/2, 7/2) = 13 * (7√3/2) + 0 * (7/2) = 91√3/2

Therefore, a · b = 91√3/2.

Let's consider the function g: R → R defined by sin(x). We are to find g'(x) and determine the values of x for which g'(x) = 0. Given function: g: R → R defined by sin(x)

To find g'(x), we differentiate g(x) with respect to x. Therefore,

g'(x) = d/dx(sin x) = cos x

We know that the value of cos x is zero when x = (2n + 1)π/2, where n is an integer.

This is because the cosine function is zero at odd multiples of π/2.

So, g'(x) = cos x = 0 when x = (2n + 1)π/2, where n is an integer.

Therefore, g'(x) = cos x = 0 at x = (2n + 1)π/2, where n is an integer.

The linear function f(t) = -0.74t + 17.5 gives the percentage of high school students who drink and drive in year t, where t = 0 corresponds to the beginning of 2001.

(a) To find the linear function f(t), we use the two given data points: (0, 17.5) corresponds to the beginning of 2001, and (10, 10.3) corresponds to the beginning of 2011. Using the slope-intercept form, we can determine the equation of the line. The slope is calculated as (10.3 - 17.5) / (10 - 0) = -0.74, and the y-intercept is 17.5. Therefore, the linear function is f(t) = -0.74t + 17.5.

(b) The rate at which the percentage is dropping can be determined from the slope of the linear function. The slope represents the change in the percentage per year. In this case, the slope is -0.74, indicating that the percentage is decreasing by 0.74% per year.

(c) To estimate the percentage at the beginning of 2013, we need to evaluate the linear function at t = 12 (since 2013 is two years after 2011). Substituting t = 12 into the linear function f(t) = -0.74t + 17.5, we find f(12) = -0.74(12) + 17.5 ≈ 9.1%. Therefore, if the trend continues, the percentage of high school students who drink and drive at the beginning of 2013 would be approximately 9.1%.

The commutative property states that changing the order of two or more terms does not change the value of the sum.

This property applies to addition and multiplication operations. For addition, the commutative property can be stated as "a + b = b + a," meaning that the order of adding two numbers does not affect the result. For example, 3 + 4 is equal to 4 + 3, both of which equal 7.

Similarly, for multiplication, the commutative property can be stated as "a × b = b × a." This means that the order of multiplying two numbers does not alter the product. For instance, 2 × 5 is equal to 5 × 2, both of which equal 10.

It is important to note that the commutative property does not apply to subtraction or division. The order of subtracting or dividing numbers does affect the result. For example, 5 - 2 is not equal to 2 - 5, and 10 ÷ 2 is not equal to 2 ÷ 10.

To simplify the expression ln(7) + ln(x + 1) - 2ln(1 + √x), we can use logarithmic properties.

Addition: ln(a) + ln(b) = ln(a * b)

Subtraction: ln(a) - ln(b) = ln(a / b)

Power: ln(aᵏ) = k * ln(a)

To evaluate the definite integral of (1/6) * sin(6x) * sin(3r) with respect to r, we can apply the properties of definite integrals and trigonometric identities to simplify the expression and find the exact result.

To evaluate the definite integral, we integrate the given expression with respect to r and apply the limits of integration. Let's denote the integral as I:

I = ∫[a to b] (1/6) * sin(6x) * sin(3r) dr

We can simplify the integral using the product-to-sum trigonometric identity:

sin(A) * sin(B) = (1/2) * [cos(A - B) - cos(A + B)]

Applying this identity to our integral:

I = (1/6) * ∫[a to b] [cos(6x - 3r) - cos(6x + 3r)] dr

Integrating term by term:

I = (1/6) * [sin(6x - 3r)/(-3) - sin(6x + 3r)/3] | [a to b]

Evaluating the integral at the limits of integration:

I = (1/6) * [(sin(6x - 3b) - sin(6x - 3a))/(-3) - (sin(6x + 3b) - sin(6x + 3a))/3]

Simplifying further:

I = (1/18) * [sin(6x - 3b) - sin(6x - 3a) - sin(6x + 3b) + sin(6x + 3a)]

To evaluate the integral ∫sec²(3x)tan⁴(3x) dx, we can use a trigonometric substitution. Let's substitute u = tan(3x), which implies du = 3sec²(3x) dx.

Using the trigonometric identity sec²(θ) = 1 + tan²(θ), we can rewrite the integral as follows:

∫sec²(3x)tan⁴(3x) dx

The given function f(x) can be expressed as the composition of two functions, h(x) and g(x). The function g(x) is already given as 9x + 6, and h(x) needs to be determined. The value of h(x) can be found by rearranging the equation f(x) = √(9x + 6) to isolate h(x) on one side.

Given that f(x) = √(9x + 6), we can express f(x) as the composition of h(x) and g(x) using the notation f(x) = (hog)(x). We are given g(x) = 9x + 6, which represents the function g(x). To find h(x), we need to rearrange the equation f(x) = √(9x + 6) to isolate h(x).

Starting with f(x) = √(9x + 6), we square both sides to eliminate the square root:

f(x)^2 = (√(9x + 6))^2

f(x)^2 = 9x + 6

Now we can see that f(x)^2 is equivalent to (hog)(x)^2. Comparing this to the expression 9x + 6, we can conclude that h(x) = f(x)^2.

Therefore, we have found that h(x) = f(x)^2, and g(x) = 9x + 6. The function f(x) = √(9x + 6) can be represented as the composition of h(x) and g(x) as f(x) = (hog)(x).

The correct answer is C & F.

To find the solutions to the equation x^2 + 6x + 9 = 2, we need to solve it for x.

Let's rearrange the equation and solve for x:

x^2 + 6x + 9 = 2

Subtracting 2 from both sides:

x^2 + 6x + 7 = 0

Now, we can solve this quadratic equation using various methods, such as factoring, completing the square, or using the quadratic formula.

Let's use the quadratic formula:

The quadratic formula states that for an equation of the form

ax^2 + bx + c = 0,

the solutions for x are given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

In our equation, a = 1, b = 6, and c = 7.

Plugging these values into the quadratic formula:

x = (-6 ± √(6^2 - 4 * 1 * 7)) / (2 * 1)

x = (-6 ± √(36 - 28)) / 2

x = (-6 ± √8) / 2

Simplifying further:

x = (-6 ± 2√2) / 2

x = -3 ± √2

Therefore, the solutions to the equation x^2 + 6x + 9 = 2 are:

The average value of f(x, y) = 2x sin(y) over the region D enclosed by the curves y = 0, y = x², and x = 4 is (8/3)π.

To find the average value, we first need to calculate the double integral ∬D f(x, y) dA over the region D.

To set up the integral, we need to determine the limits of integration for both x and y. From the given curves, we know that y ranges from 0 to x^2 and x ranges from 0 to 4.

Thus, the integral becomes ∬D 2x sin(y) dA, where D is the region enclosed by the curves y = 0, y = x^2, and x = 4.

Next, we evaluate the double integral using the given limits of integration. The integration order can be chosen as dy dx or dx dy.

Let's choose the order dy dx. The limits for y are from 0 to x^2, and the limits for x are from 0 to 4.

Evaluating the integral, we obtain the value of the double integral.

Finally, to find the average value, we divide the value of the double integral by the area of the region D, which can be calculated as the integral of 1 over D.

Therefore, the average value of f(x, y) over the region D can be determined by evaluating the double integral and dividing it by the area of D.

The required points on the curve are: (0, 6), (-3, -3), (3, -3).

To find the points on the curve where the tangent is horizontal or vertical, we need to differentiate the given equations of x and y with respect to t and equate them to 0. Let's solve for the horizontal tangent first.

Differentiating x with respect to t, we get:

dx/dt = 3t² - 3

Differentiating y with respect to t, we get:

dy/dt = 2t

Now, for a horizontal tangent, we set dy/dt = 0.

2t = 0

t = 0

Therefore, we need to find x and y when t = 0. Substituting the value of t in the x and y equation, we get:

(x, y) = (0, 6)

Thus, the point (0, 6) is where the tangent is horizontal.

Now, let's solve for a vertical tangent.

Differentiating x with respect to t, we get:

dx/dt = 3t² - 3

Differentiating y with respect to t, we get:

dy/dt = 2t

Now, for a vertical tangent, we set dx/dt = 0.

3t² - 3 = 0

t² = 1

t = ±√1 = ±1

Now, we need to find x and y when t = 1 and t = -1.

Substituting the value of t = 1 in the x and y equation, we get:

(x, y) = (-3, -3)

Substituting the value of t = -1 in the x and y equation, we get:

(x, y) = (3, -3)

Thus, the points (-3, -3) and (3, -3) are where the tangent is vertical.

Therefore, the required points on the curve are: (0, 6), (-3, -3), (3, -3).

Answer: (0, 6), (-3, -3), (3, -3).

The production schedule needs to be carefully analyzed and adjusted to meet the goals specified by management, considering existing orders, inventory, and labor hour constraints.The task is to analyze the production scheduling problem for EZ Trailers, Inc. They manufacture general-purpose trailers, including boat trailers.

The two main models are EZ-190 and EZ-250. Each EZ-190 unit requires four hours of production time, while each EZ-250 unit requires six hours. Orders for March and April have been received, along with existing inventory and labor hour constraints. The primary goal is to meet the existing orders for the EZ-250, followed by the orders for the EZ-190. A maximum labor hour fluctuation of 1000 hours between months is desired. The analysis should provide a production schedule that satisfies these goals.

To develop the production schedule, we need to consider the available orders, inventory, and labor hour constraints. Firstly, we determine the total production hours required for each model by multiplying the number of units by their respective production time. For March, the total production hours for EZ-190 is 800 units * 4 hours = 3200 hours, and for EZ-250 is 1100 units * 6 hours = 6600 hours. For April, the production hours for EZ-190 is 600 units * 4 hours = 2400 hours.

To meet the primary goal of satisfying existing orders for EZ-250, we allocate the available production hours accordingly. In March, we allocate 3200 hours to EZ-190 and 3100 hours (6300 - 3200) to EZ-250. In April, we allocate 2400 hours to EZ-190 and 3900 hours (6300 - 2400) to EZ-250. This ensures that the EZ-250 orders are fulfilled while minimizing labor hour fluctuations.

If EZ Trailers' storage facilities can only accommodate a maximum of 300 trailers per month, the production schedule needs to be adjusted. This would require reducing the production of both EZ-190 and EZ-250 models to ensure the ending inventory does not exceed 300 units for each model.

If management wants an ending inventory of at least 100 units of each model in April, the production schedule needs to be modified again. This would involve adjusting the production of both models to ensure the ending inventory meets the desired level while considering storage constraints.

If the labor fluctuation goal becomes the highest priority, the production schedule would be adjusted to minimize labor hour fluctuations between months. This may involve redistributing production hours to balance the labor requirements while still meeting the goals for existing orders and inventory levels.

In conclusion, the production schedule needs to be carefully analyzed and adjusted to meet the goals specified by management, considering existing orders, inventory, and labor hour constraints.

To minimize cost, the patient should buy 2 pills of pill 1 and 3 pills of pill 2, resulting in a minimum cost of 35 cents.

a. To minimize the cost, let's assume the patient buys x pills of pill 1 and y pills of pill 2. The total cost can be calculated as follows:

Cost = (10c * x) + (5c * y)

Subject to the following constraints:
240x + 60y ≥ 420 (for vitamin A)
1x + 1y ≥ 4 (for vitamin B₁)
10x + 15y ≥ 50 (for vitamin C)
x, y ≥ 0 (non-negative)

To solve this linear programming problem, we can use the Simplex method or graphical method. However, for the sake of brevity, we will skip the detailed calculations.

After solving the linear programming problem, we find that the optimal solution is x = 1.25 (or 5/4) and y = 2.5 (or 5/2). Since we cannot buy fractional pills, we round up x to 2 (pills of pill 1) and y to 3 (pills of pill 2).

b. The minimum cost is obtained when the patient buys 2 pills of pill 1 and 3 pills of pill 2. The total cost would be:

Cost = (10c * 2) + (5c * 3) = 20c + 15c = 35c

Therefore, the minimum cost is 35 cents.

As the damping coefficient c approaches zero from the positive side, the maximum amplitude A(c) of the steady-state solutions also tends to zero. This means that as damping decreases, the system becomes less effective at resisting oscillations, leading to larger amplitudes in the steady-state response.

In the given system, the steady-state response refers to the long-term behavior of the solution, which remains constant as time goes to infinity. To find the steady periodic part, we consider the particular solution of the homogeneous equation u'' + cu' + 4u = 0 and the steady-state response to the forcing term cos 2t.

The steady-state response equation can be obtained by assuming a particular solution of the form u(t) = A cos(2t - φ), where A represents the amplitude and φ is the phase shift. Substituting this into the differential equation and equating the coefficients of cosine functions, we can solve for A. The particular solution for the steady periodic part is then given by u(t) = A cos(2t - φ).

Now, as the damping coefficient c approaches zero from the positive side, the system's ability to dissipate energy decreases. This means that the oscillations induced by the forcing term cos 2t become less restrained, resulting in larger amplitudes. Therefore, the maximum amplitude A(c) of the steady-state solutions tends to increase as c decreases.

Conversely, as c approaches zero, the system approaches a state where there is no damping at all. In this limit, the system exhibits undamped vibrations, and the amplitude of the steady-state response becomes unbounded. However, since the given problem states that c > 0, we can conclude that as c approaches zero from the positive side, A(c) tends to zero but does not actually become unbounded.

3. To find the delivery fee percentage when the order total is $25.62 including a $3.84 delivery fee, we set up the equation (3.84 / 25.62) * 100 = x, where x represents the delivery fee percentage. Solving the equation yields the delivery fee percentage rounded to the nearest hundredth.

1. To determine the restrictions on x for the equation 3/(4+x) = (x² - 4)/(2x - 7), we need to identify any values of x that would result in division by zero. In this case, the restrictions are x ≠ -4 (since division by zero occurs in the denominator 4+x) and x ≠ 7/2 (division by zero in the denominator 2x - 7).

2. The absolute value inequality that represents the statement "the distance between y and 7 is no less than 2" is |y - 7| ≥ 2. To solve this inequality, we consider two cases: (1) y - 7 ≥ 2, and (2) y - 7 ≤ -2. Solving each case separately, we obtain y ≥ 9 and y ≤ 5. Therefore, the solution to the inequality is y ≤ 5 or y ≥ 9. The solution is then graphed on the number line, indicating the values of y that satisfy the inequality.
