To find the interval(s) over which the function -3x^2+12 is decreasing, we need to find the critical points of the function and test the sign of the derivative on either side of these points.

The derivative of the function -3x^2+12 is -6x.

Setting the derivative equal to zero to find the critical points:

-6x = 0

x = 0

Testing the sign of the derivative on either side of x = 0:

-6x is negative for x > 0, meaning the function is decreasing on the interval (0, infinity).

-6x is positive for x < 0, meaning the function is increasing on the interval (-infinity, 0).

Therefore, the interval over which the function -3x^2+12 is decreasing is (0, infinity).

It's crucial to take a collaborative approach and involve employees in the change process as much as possible.

In the unfreezing stage, it is important to gather information and input from various stakeholders in order to influence change effectively. Therefore, asking the VP and analyst questions such as "What do you think are the areas that need improvement in our current system?" or "How do you think changing the system would benefit our organization?" can provide valuable insight into the motivation for change.

Surveying a sample set of employees at each location to ask their opinions on the current system and whether they think changes are necessary is also a good approach. This can help to identify common pain points and gauge the level of employee buy-in for potential changes. It's important to also consider other factors such as the cost and feasibility of implementing changes, as well as potential risks and benefits.

Mandating change without proper analysis and buy-in from employees may lead to resistance and resentment. Ultimately, the decision to change or not should be based on a thorough assessment of the situation, including feedback from stakeholders and the potential impact on the organization.

Answer:

Step-by-step explanation:

The diameter of each bead is 1.5 millimeters, which means the radius of each bead is 0.75 millimeters (since radius = diameter/2).

The volume of a sphere is given by the formula V = (4/3)πr^3.

Substituting the radius of each bead into the formula, we get:

V = (4/3)π(0.75)^3 ≈ 1.7671 cubic millimeters

To find the total volume of the 360 beads used to create the border of the picture frame, we can simply multiply the volume of one bead by the total number of beads:

Total volume = 360 × 1.7671 ≈ 635.76 cubic millimeters

Therefore, the approximate total volume of the beads that form the border of the picture frame is about 635.76 cubic millimeters.

The length of each piece of wood is 0.725 feet.

We are given that the Length= 3.5feet

Now,

This is a word problem that can be solved by using algebra and arithmetic.

Part A: Let x be the length of each of the four pieces of wood he cut. Then, according to the problem, we have:

4x + 0.6 = 3.5

This is the equation that could be used to determine the length of each piece of wood.

Part B: We know the equation from part A is correct because it represents the total length of the wood before and after cutting. The left side of the equation is the sum of the lengths of the four pieces of wood and the leftover piece of wood. The right side of the equation is the original length of the wood. Since cutting does not change the total length of the wood, these two sides must be equal.

Part C: To solve the equation from part A, we need to isolate x by using inverse operations. We get:

4x + 0.6 = 3.5 4x = 3.5 - 0.6 (subtract 0.6 from both sides) 4x = 2.9 x = 2.9/4 (divide both sides by 4) x = 0.725

Therefore, by the algebra the answer will be 0.725 feet.

Answer:

-4 or 4

Step-by-step explanation:

We can solve for the value of y by using the first equation to express y in terms of x and then substituting the resulting expression for y into the second equation.

From the first equation, we have:

4x - y = 4

Rearranging this equation to solve for y, we get:

y = 4x - 4

Now, we can substitute this expression for y into the second equation:

2x^2 - y = 4

Replacing y with 4x - 4, we get:

2x^2 - (4x - 4) = 4

Expanding the brackets and simplifying, we get:

2x^2 - 4x + 4 = 4

Subtracting 4 from both sides, we get:

2x^2 - 4x = 0

Factorizing, we get:

2x(x - 2) = 0

Using the zero product property, we see that this equation is satisfied when either 2x = 0 or x - 2 = 0.

If 2x = 0, then x = 0, and we can use the expression for y that we found earlier to get:

y = 4x - 4 = 4(0) - 4 = -4

If x - 2 = 0, then x = 2, and again using the expression for y, we get:

y = 4x - 4 = 4(2) - 4 = 4

Therefore, the possible values of y are -4 and 4. We would need more information to determine which value of y is the correct one in this context.

The possible values of x are numbers greater than 2, that is x > 2. The square have a greater area than the rectangle, and the difference in areas is 1 cm²

All values equal to or less than 2 will result to either negative or a zero for the width of the rectangle, thus only numbers greater than 2 can give positive side lengths so possible values of x > 2.

If x = 3 then;

Area of rectangle = 3 cm × (3 - 2) cm

Area of rectangle = 3 cm²

Area of square = (3 - 1)cm × (3 - 1) cm

Area of square = 2 cm × 2 cm

Area of square = 4 cm²

For any value of x greater 2, the difference in the areas is 1 cm²

Therefore, the possible values of x are numbers greater than 2, that is x > 2. The square have a greater area than the rectangle, and the difference in areas is 1 cm²

8/105 is the probability of selecting a red jelly bean the first draw and a blue jelly bean on the second draw, Therefore option C is correct.

The probability of selecting a red jelly bean on the primary draw is 8/(8+2+4+7) = 8/21, for the reason that there are 8 red jelly beans out of a complete of 8+2+4+7 = 21 jelly beans.

Since the jelly bean is not returned to the jar after the first draw, the number of jelly beans in the jar decreases through 1. consequently, on the second draw, there are 20 jelly beans left within the jar.

Out of those 20 jelly beans, 4 are blue. for that reason, the possibility of selecting a blue jelly bean on the second one draw, given that a red jelly bean was selected on the first draw, is 4/20 = 1/5.

To discover the probability of both events going on collectively & we multiply the probabilities of the 2 events:

P(red on 1st and Blue on 2d) = P(red on 1st) * P(Blue on 2nd | red on 1st)

P(red on 1st and Blue on 2nd) = (8/21) * (1/5)

P(red on 1st and Blue on 2nd) = 8/105

Answer:

(0, -3) and (3, -5)

Step-by-step explanation:

To graph the line of the equation f(x) = -2/3x - 3, we can choose any two points on the line. One way to do this is to find the y-intercept and another point using the slope of the line.

1. To find the y-intercept, let x = 0 and solve for y:

f(0) = -2/3(0) - 3 = -3

So the y-intercept is (0, -3).

2. To find another point, we can use the slope of the line, which is -2/3. We can start from the y-intercept (0, -3) and move down 2 units (since the slope is negative) and to the right 3 units (since the denominator of the slope is 3) to get another point on the line:

(3, -5)

So the two points we can use to graph the line are (0, -3) and (3, -5).

If the function's f(x) = |x|, graph is shifted right by 3 units, and vertically stretched by a factor of "4", then function which best describes the transformed-function is 4|x-3|.

Let the transformed function be : g(x); The transformed function g(x) is obtained by applying two transformations to the original function f(x) = |x|.

The "first-transformation" is to make a "horizontal-shift" (right-shift) of 3 units. This means that the entire graph of the function is shifted to the right by 3 units, so, function becomes |x-3|.

The "second-trans-formation" is to stretch the graph vertically by a factor of 4. This means that the entire graph of the function is stretched vertically,

Now, the function becomes, g(x) = 4|x-3|.

Therefore, the transformed function is 4|x-3|.
