Answer:
Let one integer be x, and the other be (x+2)
x(x+2)=224
x2+2x-224=0
(x+16)(x-14) =0
x=-16 or 14
so x+2 = -14 or 16
So the integers are either 14 and 16 or -14 and -16.
Step-by-step explanation:
was that the question?
Let the first consecutive even number be x. The second one is going to be two more than x, and as such can be written as (x+2).
The product of these numbers, x and (x+2), is 224:
x(x+2)=224
x²+2x=224
x²+2x-224=0
(x+16)(x-14) =0 (could also use '-b' method)
x=-16 or 14
Therefore, (x+2) = -14 or 16
Therefore, the numbers are either 14 and 16, or -14 and -16

what is the approximate volume of the sphere ? use 3.14 to approximate pi and round to the hundredth is necessary. (3 in)
The required, approximate volume of the sphere is 113.04 cubic inches.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
Here,
The formula for the volume of a sphere is V = (4/3)πr³, where r is the radius of the sphere.
If the radius of the sphere is 3 inches, we can substitute this value into the formula and use 3.14 to approximate π,
V = (4/3) x 3.14 x 3³
V = (4/3) x 3.14 x 27
V = 113.04 cubic inches
Therefore, the approximate volume of the sphere is 113.04 cubic inches.

a researcher asks each of twenty people to fill out a survey. then she asks each of those people to give a blank copy of the same survey to five other people of his or her sex, age, and weight range. in this way, 120 surveys are distributed. what is the sampling technique?
The sampling technique used by the researcher in this scenario is known as "snowball sampling".
Snowball sampling is a non-probability sampling technique that is used when the desired sample characteristic is rare or difficult to find. In this technique, the researcher starts with a small group of initial participants (in this case, the twenty people who filled out the survey) and then ask those participants to recruit additional participants who meet the same criteria (in this case, five other people of the same sex, age, and weight range).
This process continues until the desired sample size is reached (in this case, 120 surveys). Snowball sampling is often used in social science research and can be a useful way to reach populations that are difficult to access through other sampling methods.
However, it is important to note that snowball sampling does not produce a representative sample, and therefore the results cannot be generalized to the larger population.

You sell your bicycle to your friend for 65$ your friend gives you x five dollar bills and y ten dollar bills. There are a total of 9 bills. How many five dollar and ten dollars bills did your friend give you?
Answer:
There are \(5\) five dollar bills and \(4\) ten dollar bills.
Step-by-step explanation:
Given:
Selling price of bicycle \(=\$65\).
The friend gave \(x\) five dollar bills and \(y\) ten dollar bills.
Total number of bills \(=9\).
To find: Number of five dollar bills and ten dollar bills the friend gave.
Solution:
The friend gave \(x\) five dollar bills and \(y\) ten dollar bills and the friend gave \(9\)bills in all.
So, \(x+y=9\).
\(\Rightarrow x=9-y ...(i)\)
Selling price of bicycle \(=\$65\).
So, \(5x+10y=65...(ii)\)
Putting the value of \(x\) from equation \((i)\) in equation \((ii)\).
\(\Rightarrow 5(9-y)+10y=65\)
\(\Rightarrow 45-5y+10y=65\)
\(\Rightarrow 45+5y=65\)
\(\Rightarrow 5y=65-45\)
\(\Rightarrow 5y=20\)
\(\Rightarrow y=\frac{20}{5}\)
\(\Rightarrow y=4\)
Now, putting the value of \(y\) in equation \((i)\).
\(\Rightarrow x=9-4\)
\(\Rightarrow x=5\)
Hence, there are \(5\) five dollar bills and \(4\) ten dollar bills.

A jeweler makes a pair of earrings by cutting two 50^{\circ} sectors from a silver disk.
a. Find the area of each sector.
a. The area of each sector is 1.7 cm^2
b. If the weight of the silver disk is 2.3 grams, the silver wedge for each earring weighs approximately 319.4 milligrams.
Answer:
a. To find the area of each sector, we need to use the formula for the area of a sector: A = (θ/360°) * π * r^2, where θ is the central angle of the sector and r is the radius of the disk.
Given that the central angle is 50° and the radius is 2 cm, we can substitute these values into the formula:
A = (50°/360°) * π * (2 cm)^2
Simplifying the calculation:
A = (5/36) * π * 4 cm^2
A ≈ 1.7 cm^2
Therefore, the area of each sector is approximately 1.7 cm^2.
b. To find the weight of the silver wedge for each earring, we need to calculate the weight per unit area.
Given that the weight of the silver disk is 2.3 grams and the area of each sector is 0.694 cm^2, we can use the formula:
Weight per unit area = Total weight / Total area
Substituting the given values:
Weight per unit area = 2.3 grams / (2 * 0.694 cm^2)
Simplifying the calculation:
Weight per unit area ≈ 0.3194 grams/cm^2
To convert grams to milligrams, we can use the conversion factor 1 gram = 1000 milligrams. Therefore, the weight per unit area in milligrams is:
Weight per unit area ≈ 0.3194 grams/cm^2 * 1000 milligrams/gram
Simplifying the calculation:
Weight per unit area ≈ 319.4 milligrams/cm^2
Therefore, the silver wedge for each earring weighs approximately 319.4 milligrams.

To calculate the HDD for the month of January in State College, PA, we need to first determine the base temperature. The base temperature is the temperature below which a building needs to be heated in order to maintain a comfortable indoor temperature. In this case, we will use a base temperature of 65 degrees F.
To calculate the HDD, we need to subtract the average daily temperature from the base temperature and sum up the values for each day of the month. If we assume that January has 31 days, we can calculate the HDD as follows:
HDD = (65 - 35) x 31
HDD = 930
So the HDD for the month of January in State College, PA is 930. This means that during the month of January, there were 930 heating degree days, which indicates the amount of heating required to maintain a comfortable indoor temperature. It is important to note that the HDD can vary depending on the base temperature used, so it is important to choose a base temperature that is appropriate for the climate and the building being heated.

Step-by-step explanation:
there is Q yiur welcome hope that helps :)
Answer:
m ∠Q = 90°
m ∠ R = 37°
m ∠ S = 53°
Step-by-step explanation:
Given the right ΔRQS, where:
m ∠ Q = 90°
m ∠ R = (5x - 13)°
m ∠ S = (3x + 23)°
Since the sum of all the angles of a triangle add up to 180°, we can set up the following equation to find the value of x and the measures of each angle:
m ∠ Q + m ∠ R + m ∠ S = 180°
90° + (5x - 13)° + (3x + 23)° = 180°
90° + 5x° - 13° + 3x° + 23° = 180°
Combine like terms:
100° + 8x = 180°
Subtract 100° from both sides:
100° - 100° + 8x = 180° - 100°
8x° = 80°
Divide both sides by 8:
\(\frac{8x}{8} = \frac{80}{8}\)
x = 10°
Substitute the value of x to find the measure of each angle:
m ∠ Q = 90°
m ∠ R = (5x - 13)° = 5(10) - 13 = 37°
m ∠ S = (3x + 23)° = 3(10) + 23 = 53°
Solve the following 0-1 integer programming model problem by implicit enumeration.

2x 2 +x 3 ≥2
3x 1 +3x 2 +3x 3 ≥6
x 1 ,x 2 ,x 3 ∈{0,1}
The given problem is a 0-1 integer programming problem, which involves finding the maximum value of a linear objective function subject to a set of linear constraints, with the additional requirement that the decision variables must take binary values (0 or 1).
To solve this problem by implicit enumeration, we systematically evaluate all possible combinations of values for the decision variables and check if they satisfy the constraints. The objective function is then evaluated for each feasible solution, and the maximum value is determined.
In this case, there are three decision variables: x1, x2, and x3. Each variable can take a value of either 0 or 1. We need to evaluate the objective function 2x1 - x2 - x3 for each feasible solution that satisfies the given constraints.
By systematically evaluating all possible combinations, checking the feasibility of each solution, and calculating the objective function, we can determine the solution that maximizes the objective function value.
The explanation of the solution process, including the enumeration of feasible solutions and the calculation of the objective function, can be done using a table or a step-by-step analysis of each combination.
This process would involve substituting the values of the decision variables into the constraints and evaluating the objective function. The maximum value obtained from the feasible solutions will be the optimal solution to the problem.

Compare h () to the parent function f(0) = cos(0) which statements are true? Select all that apply
Picture included!:)
While h(x) and f(x) = cos(x) have some differences in their graphs, they share important similarities such as periodicity and amplitude.
Based on the provided picture, h(x) is the function in blue while f(x) = cos(x) is the function in red.
To compare h(x) to the parent function f(x) = cos(x), we need to analyze their similarities and differences.
First, we can observe that both functions are periodic with a period of 2π. This means that the graphs of h(x) and f(x) repeat themselves every 2π units.
Second, both functions have an amplitude of 1. This means that the maximum distance between the graphs and the x-axis is 1 unit.
Third, we can observe that the graph of h(x) is a translation of the graph of f(x) = cos(x). Specifically, the graph of h(x) is shifted 1 unit to the right and 1 unit up compared to the graph of f(x).
Therefore, the following statements are true:
- Both h(x) and f(x) = cos(x) are periodic with a period of 2π.
- Both h(x) and f(x) = cos(x) have an amplitude of 1.
- The graph of h(x) is a translation of the graph of f(x) = cos(x) by 1 unit to the right and 1 unit up.
In summary, while h(x) and f(x) = cos(x) have some differences in their graphs, they share important similarities such as periodicity and amplitude.

Answer: See below
Step-by-step explanation:
For part a, we are given that the triangle is an isosceles triangle. That means the two sides that are marked are equal to each other. We set DE and EF equal to each other to find x.
5x-3=3x+7 [subtract both sides by 3x]
2x-3=7 [add both sides by 3]
2x=10 [divide both sides by 2]
x=5
We now know the value of x is 5.
For part b, all we have to do is plug in x=5 to find the length of each leg.
5(5)-3 [multiply]
25-3 [subtract]
DE=22 in
3(5)+7 [multiply]
15+7 [add]
EF=22 in
Now, we have the length of each leg. DE=22 in, EF=22 in
For part c, we do the same as above and plug in x=5 to find the length of the base.
