Debbie is using the method of "exhaustive search" or "brute-force" problem solving to ensure 100% accuracy in finding the last three words in her word search.

In an exhaustive search, all possible solutions or combinations are systematically checked or examined to find the correct answer.

Debbie is looking at every possible word combination in order to locate the three words she is having difficulty finding.

By examining each combination, she eliminates the possibility of missing any potential solutions and ensures a comprehensive search of all options.

While this approach guarantees accuracy, it can be time-consuming and resource-intensive, especially when dealing with a large number of possibilities.

However, in Debbie's case, she is committed to achieving a 100% accurate solution by considering every single word combination.

As Debbie completes her daily word search there are three words she is having difficult finding. In order to be sure to solve the problem with 100% accuracy, she looks at every possible word combination to find these last three words. What method of problem solving is Debbie using ??

Answer: 1. multiplication

Step-by-step explanation:

Suppose that you want to change an object with length L with a scale factor a, then the lenght of the rescaled object will be:

L' = a*L

Then the correct option is 1) multiplication.

Notice that sometimes you may find that the scale factor is a number like 1/5 and when you find the new lenght you will end with something like:

L' = L/5 that seems like a division, but this is actually the multiplication between L and 1/5.

The Histogram is explained in the solution below.

To create a histogram of the given data, we need to determine the frequency of each value and represent it graphically.

Here's a histogram for the provided data:

Number of Customers   Frequency

0 - 5                                        **

5 - 10                                       ***

10 - 15                                     ****

15 - 20                                    *****

20 - 25                                      **

In this histogram, the x-axis represents the ranges of the number of customers (e.g., 0-5, 5-10, etc.), and the y-axis represents the frequency of occurrence for each range.

The asterisks (*) indicate the frequency of customers falling within each range.

To generate the histogram, you count the occurrences of each value within the given ranges.

For example, there are 2 occurrences () of values between 0-5, 3 occurrences (*) between 5-10, and so on.

Answer:

The time the object will hit the ground is 2 s.

Step-by-step explanation:

Given;

h(t) = (-4.9t + 29.4)(t + 2)

Open the bracket;

h(t) = -4.9t² + 29.4t  -9.8t + 58.8

h(t) = -4.9t²  + 19.6t + 58.8

When the  object hit the ground, the final velocity will be zero;

\(v = \frac{dh}{dt} = 0 \\\\\frac{dh}{dt} = -9.8t + 19.6 = 0\\\\9.8t = 19.6\\\\t = \frac{19.6}{9.8} \\\\t = 2 \ s\)

Therefore, the time the object will hit the ground is 2 s.

The volume of the solid is 1.5 cubic units. From the solid in the first octant under the plane z = x + y, above the surface z = xy, and enclosed by the surfaces x = 0, y = 0, and x2 + y2 = 4

To find the volume of the solid by subtracting two volumes, we need to find the limits of integration for x, y, and z.

From the given information, we know that the solid is in the first octant and is enclosed by the surfaces x = 0, y = 0, and x2 + y2 = 4. Thus, the limits of integration for x and y are 0 to 2 since the radius of the circle x2 + y2 = 4 is 2.

Next, we need to find the limits of integration for z. To do this, we need to set the two given equations equal to each other:

xy = x + y

xy - x - y = 0

Using partial fraction decomposition:

xy - x - y = (x - 1)(y - 1) - 1

So, we have:

(x - 1)(y - 1) = z - 1

Thus, the limits of integration for z are 1 to 3.

Now, we can set up the integral to find the volume:

V = ∫∫∫ dV

V = ∫0^2 ∫0^(2 - x) ∫1^(x + y) dz dy dx

Evaluating this integral, we get the volume of the solid as 1.5 cubic units.

Step-by-step explanation:

Got the answer from the test because I got it wrong and it said this was the right answer.

Amir's search for Hassan and the blue kite occurs in the novel "The Kite Runner" by Khaled Hosseini. The two men Amir encounters mock Hassan primarily because of his Hazara ethnicity, which is a marginalized and discriminated group in Afghanistan.

Hassan's social status is further complicated by the fact that he is Amir's family's servant, emphasizing the existing class differences between them. The novel portrays the social and cultural tensions in Afghanistan during that period, highlighting the disparities between the dominant Pashtun ethnic group, which Amir belongs to, and the Hazara minority. These disparities manifest in various forms of prejudice, including mockery, which further emphasizes the power dynamics at play.

In this particular scene, the men's mockery of Hassan is an attempt to belittle and demean him, thereby reinforcing the status quo that supports their own position within the social hierarchy. Amir's reaction to the situation also sheds light on his  internal struggle with loyalty, friendship, and personal identity.

In conclusion, the men mock Hassan due to his Hazara ethnicity and his position as a servant in Amir's household, reflecting the societal prejudices and power imbalances present in Afghanistan during that time.

Salute.

The circumference of the circle with a radius of 6 feet would be approximately 37.7 feet.

The circumference of a circle is the distance around the outer edge of the circle. It is the perimeter of the circle, which is the total length of the boundary that encloses the area of the circle.

The formula for the circumference of a circle is

C = 2πr

Where C is the circumference, r is the radius, and π is approximately 3.14.

If a circle has a radius of 3 feet, the circumference would be

C = 2πr

C = 2π(3)

C ≈ 18.85 feet

When the radius doubles to 6 feet, the circumference would be

C = 2πr

C = 2π(6)

C ≈ 37.7 feet

Maximize 2x1 + 3x2 + 5x3 subject to x1 + x2 + x3 ≤ 1500, x1 + x2 ≤ 1100, x2 ≤ 800, x3 ≤ 400.

2. Using Excel Solver, find the optimal allocation of funds.

3. The maximum value of the objective function is reported by Excel Solver.

We have,

Objective Function and Constraints:

Let:

x1 = amount spent on food

x2 = amount spent on shelter

x3 = amount spent on entertainment

Objective Function:

Maximize: 2x1 + 3x2 + 5x3 (since each dollar spent on food has a satisfaction value of 2, each dollar spent on shelter has a satisfaction value of 3, and each dollar spent on entertainment has a satisfaction value of 5)

Constraints:

Subject to:

x1 + x2 + x3 ≤ $1,500 (maximum disposable income)

x1 + x2 ≤ $1,100 (amount spent on food and shelter combined must not exceed $1,100)

x2 ≤ $800 (amount spent on shelter alone must not exceed $800)

x3 ≤ $400 (entertainment cannot exceed $400)

Using Excel Solver:

In Excel, set up a spreadsheet with the following columns:

Column A: Variable names (x1, x2, x3)

Column B: Objective function coefficients (2, 3, 5)

Column C: Constraints coefficients (1, 1, 1) for the first constraint (maximum disposable income)

Column D: Constraints coefficients (1, 1, 0) for the second constraint (amount spent on food and shelter combined)

Column E: Constraints coefficients (0, 1, 0) for the third constraint (amount spent on shelter alone)

Column F: Constraints coefficients (0, 0, 1) for the fourth constraint (entertainment limit)

Column G: Right-hand side values ($1,500, $1,100, $800, $400)

Apply the Excel Solver tool with the objective function and constraints to find the optimal allocation of funds.

Once the Excel Solver completes, it will report the maximum value of the objective function, which represents the optimal satisfaction value achieved within the given budget constraints.

Thus,

Objective Function and Constraints: Maximize 2x1 + 3x2 + 5x3 subject to x1 + x2 + x3 ≤ 1500, x1 + x2 ≤ 1100, x2 ≤ 800, x3 ≤ 400.

The range of the function f(x) = log5x is (-∞, +∞).The function f(x) = log5x represents the logarithm base 5 of x. To determine the range of this function, we need to consider the possible values that the logarithm can take.

The range of the logarithm function y = log5x consists of all real numbers. The logarithm function is defined for positive real numbers, and as x approaches 0 from the positive side, the logarithm approaches negative infinity. As x increases, the logarithm function approaches positive infinity.

The range of the function is the set of all possible output values. In this case, the range consists of all real numbers that can be obtained by evaluating the logarithm

log5(�)log 5 (x) for �>0 x>0.

Since the base of the logarithm is 5, the function log5x will take on all real values from negative infinity to positive infinity. Therefore, the range of the function f(x) = log5x is (-∞, +∞).

In other words, the function can output any real number, ranging from negative infinity to positive infinity. It does not have any restrictions on the possible values of its output.

Step-by-step explanation:

The half-life of a radioactive substance refers to the time it takes for half of the substance to decay. In this case, the substance decayed to 95% of its original amount after one year.

To find the half-life, we need to determine how much of the substance is left after one half-life. Since the substance decayed to 95% of its original amount, it means that 5% has decayed.

Now, let's set up an equation to solve for the half-life. We know that after one half-life, only 50% of the substance will remain. So, we can set up the following equation:
100% - 5% = 50%

Simplifying the equation, we get:
95% = 50%
To find the half-life, we need to determine how many times 5% can be halved to reach 50%.
Let's divide 95% by 5%:
95% ÷ 5% = 19
Therefore, it takes 19 half-lives for the substance to decay to 50% of its original amount.

Since we know that the substance decays to 50% of its original amount after one year, we can divide one year by 19 to find the half-life.
1 year ÷ 19 = 0.0526 years
Rounding to two decimal places, the half-life of the substance is approximately 0.05 years.

In summary, the half-life of the radioactive substance is approximately 0.05 years.
