Walmart's decision to use its own fleet of trucks to pick up products directly from manufacturers and deliver them to its stores is a strategic move that has the potential to benefit both Walmart and manufacturers.

By using its own fleet, Walmart will be able to cut down on transportation costs and gain more control over the supply chain, which can lead to better efficiency and cost savings. This is especially important given Walmart's massive scale, with over 4,000 stores in the US alone.

For manufacturers, this move by Walmart could be a relief as they can focus on their core competency of making products rather than managing logistics. With Walmart taking over the transportation aspect, manufacturers can rest assured that their products will be delivered on time and in the right condition.

The fact that Walmart already has a large fleet of trucks and trailers means that it has the capacity to implement this new program without too much additional investment. However, it remains to be seen how manufacturers will respond to this proposal, as they may have existing contracts with other carriers or may be hesitant to rely too heavily on Walmart for their transportation needs.

Overall, Walmart's move towards using its own fleet of trucks is a smart one that has the potential to benefit both the retailer and its suppliers.

The standard parametric equations for the tangent line to the curve r(t) at t = T₀ = 4 are: x = 24(t-4) + 48, y = 15(t-4) - 3, z = 64(t-4) + 64

To find the parametric equations for the tangent line to the curve r(t) at t = T₀ = 4, we can follow these steps:

Step 1: Find the point on the curve at t = T₀.

To find the point on the curve at t = T₀ = 4, we simply evaluate r(4):

r(4) = 3(4²)i + (4(4)-1)j + 4³k

= 48i + 15j + 64k

So the point on the curve at t = 4 is (48, 15, 64).

Step 2: Find the direction of the tangent line at t = T₀.

To find the direction of the tangent line, we need to take the derivative of r(t) and evaluate it at t = 4. So we first find r'(t):

r'(t) = 6ti + 4j + 3t²k

Then we evaluate r'(t) at t = 4:

r'(4) = 6(4)i + 4j + 3(4²)k

= 24i + 4j + 48k

So the direction of the tangent line at t = 4 is the vector <24, 4, 48>.

Step 3: Write the parametric equations for the tangent line.

To write the parametric equations for the tangent line, we use the point and direction found in steps 1 and 2. We can write the parametric equations as:

x = 48 + 24(t-4)

y = 15 + 4(t-4)

z = 64 + 48(t-4)

Simplifying these equations gives us:

x = 24t + 48

y = 4t - 3

z = 48t + 64

These are the standard parametric equations for the tangent line to the curve r(t) at t = 4.

In a rectangle, a diagonal forms a 36° angle with a side. To find the measure of the angle between the diagonals, which lies opposite to a shorter side, follow these steps:

1. Let's denote the angle between the diagonal and the shorter side as θ (which is given as 36°). Since the rectangle has four right angles (90°), the angle between the diagonal and the longer side can be found by subtracting θ from 90°: 90° - 36° = 54°.

2. Now, consider the right-angled triangle formed by the diagonal, shorter side, and longer side of the rectangle. The angle between the diagonal and the longer side is 54°, as calculated in step 1.

3. In a right-angled triangle, the sum of the other two angles (besides the right angle) must equal 90°. Thus, the angle opposite the shorter side in this triangle (let's call it α) can be calculated as: 90° - 54° = 36°.

4. Finally, the angle between the diagonals can be found by doubling α, as the diagonals bisect each other at a right angle: 2 * 36° = 72°.

Hence, the measure of the angle between the diagonals, which lies opposite to a shorter side, is 72°.

The function used to model the monthly profit for x trinkets produced are f(x) = -4(x - 50)(x - 250). The maximum profit occurs when 150 trinkets are produced.

The quadratic function that can be used to model the monthly profit for x trinkets produced is:

f(x) = -4(x - 50)(x - 250)

This is because the function is in the form of a quadratic equation, which is y = ax² + bx + c. In this case, a = -4, b = 1200, and c = 0. When we expand and simplify the equation, we get:

f(x) = -4x² + 1200x

This equation represents a parabola with a maximum value at x = 150. Therefore, the maximum profit occurs when 150 trinkets are produced.

The other answer choices are not correct because they are not quadratic functions. For example, f(x) = (x - 50)(x - 250) is a product of linear factors, and f(x) = 28(x - 50)(x + 250) and f(x) = (x + 50)(x + 250) have a coefficient of x² that is not equal to -4.

a) The profit at a sales level of 14 trees is $180.40.

b) The average change in profit sales is $13.96 per tree [(ΔP/Δx) = 97.75/7].

c) The instantaneous rate of change of profit at a sales level of 14 trees is $19.72 per tree.

d) The equation of the tangent line at (5, f(5)) is y = 6x - 25.

a. To find the profit at a sales level of 14 trees, we need to evaluate the profit function at x = 14:

P(x) = 20x - 0.01x^2 - 100

P(14) = 20(14) - 0.01(14)^2 - 100 = $180.40

Therefore, the profit at a sales level of 14 trees is $180.40.

b. To find the average change in profit sales from 12 to 19 trees, we need to calculate the average rate of change of the profit function over this interval:

Δx = 19 - 12 = 7

ΔP = P(19) - P(12) = (2019 - 0.0119^2 - 100) - (2012 - 0.0112^2 - 100) = $97.75

Therefore, the average change in profit sales is $13.96 per tree [(ΔP/Δx) = 97.75/7].

c. To find the instantaneous rate of change of profit at a sales level of 14 trees, we need to find the derivative of the profit function at x = 14:

P(x) = 20x - 0.01x^2 - 100

P'(x) = 20 - 0.02x

P'(14) = 20 - 0.02(14) = $19.72

Therefore, the instantaneous rate of change of profit at a sales level of 14 trees is $19.72 per tree.

d. To find the equation of the tangent line at (5, f(5)), we need to find the slope of the tangent line and its y-intercept:

f(x) = x^2 - 4x

f'(x) = 2x - 4

f'(5) = 2(5) - 4 = 6

The slope of the tangent line at (5, f(5)) is 6.

To find the y-intercept of the tangent line, we can use the point-slope form of a line:

y - f(5) = m(x - 5)

y - (5^2 - 4*5) = 6(x - 5)

y - 5 = 6x - 30

y = 6x - 25

To find the concavity, we need to find the second derivative

f(x) = x√(x^2+4)

f'(x) = √(x^2+4) + x^2/√(x^2+4)

f''(x) = -4x^3/(x^2+4)^(3/2)

The second derivative is negative for all x, which means the function is concave down on the entire interval.

To find the inflection point, we need to solve

f''(x) = 0

-4x^3/(x^2+4)^(3/2) = 0

This is true only when x = 0. Therefore, the inflection point is at x = 0.

To find the minimum and maximum, we need to find the critical points. The critical points are found by setting the first derivative equal to zero

f'(x) = √(x^2+4) + x^2/√(x^2+4) = 0

Multiplying both sides by √(x^2+4), we get

x^2+4 + x^2 = 0

If the terminal side of angle λ intersects the unit circle at point (-0. 358, 0. 934), the approximate decimal value of cot(λ) is -0.383.

To find the approximate decimal value of cot(λ), we first need to determine the values of x and y on the unit circle. Since the given point (-0.358, 0.934) lies on the unit circle, we can use the Pythagorean theorem to find the missing side:

x² + y² = 1
(-0.358)² + (0.934)² = 1
0.128 + 0.872 = 1
1 = 1

Therefore, we have x = -0.358 and y = 0.934. Since cot(λ) = cos(λ)/sin(λ), we can use the values of x and y to calculate the cosine and sine of λ:

cos(λ) = x = -0.358
sin(λ) = y = 0.934

Substituting these values into the formula for cot(λ), we get:

The critical number A is 2

To find the critical number A for the function f(x) = 7(x-2)^(2/3):

We need to first find the derivative of the function and then set it equal to zero or identify where it is undefined.

Step 1: Find the derivative of f(x).
f'(x) = d/dx[7(x-2)^(2/3)]
Using the chain rule, we get:
f'(x) = (2/3) * 7(x-2)^(-1/3) * (1)

= (14/3)(x-2)^(-1/3)

Step 2: Set the derivative equal to zero or identify where it is undefined.
The derivative will never be zero since (14/3) is a constant and (x-2)^(-1/3) will never equal zero.

However, the derivative is undefined when the exponent -1/3 leads to a division by zero in the denominator.

This occurs when (x-2) = 0.

Solving for x, we get:
x-2 = 0
x = 2

Therefore, the critical number A is 2. The two important intervals for the function f(x) = 7(x-2)^(2/3) are (-∞, 2) and (2, ∞).

Step 3: Plug the tangent values into the equation and check if the statement is true:
√3 = 3 * 0.36397

Step 4: Calculate the right side of the equation:
3 * 0.36397 = 1.09191 (approximate value)

Step 5: Compare the two values:
√3 ≈ 1.73205 (approximate value)

Since 1.73205 ≠ 1.09191, the statement "La tangente de 60° es igual al triple de la tangente de 20°" is not true.

The value of x in the data set is 101.

The mean of a data set is the sum of all the data divided by the count n.

Therefore, let's find the mean of the data set as follows:

The mean is  the sum of the data divided by the total number of data.

Hence, let's find the value of x using the mean

108  = 102 + 120 + 103 + 112 + 110 + x  / 6

108 = 547 + x / 6

Cross multiply

108 × 6 = 547 + x

648 = 547 + x

x = 648 - 547

x = 101
