what is f(3) if f(x) = 2x + 1?​

Answer:

f(2) = 24

Step-by-step explanation:

to evaluate f(2) substitute x = 2 into f(x) , that is

f(2) = 15(2) - 6 = 30 - 6 = 24

A graph of this linear function (y = -3/4x - 1) is shown in the image attached below.

A graph can be defined as a type of chart that is commonly used for the graphical representation of data on both the horizontal line (x-axis) and vertical line (y-axis) of a cartesian coordinate.

In Mathematics, the graph of any proportional relationship such as a linear function is always characterized by a straight line with all of the data points passing through the origin (0, 0) because as the values on the horizontal line (x-axis) increases or decreases, the values on the vertical line (y-axis) increases or decreases simultaneously as shown in the image attached below.

In conclusion, a graph which represents the given linear function shows a proportional relationship between the value of x and y.

Answer:

Last year's price was $12.50.

Step-by-step explanation:

We'll use the variable x to represent last year's price. First, we have to set up an equation:

.60x + x  = 13.25

We get this equation because $13.25 is 6% MORE than last year's price, meaning we need to add the original price to the increase. Next, we combine like terms and solve for x:

.06x + x = 13.25

1.06x=13.25

1.06 r   1 .06 = 13.25 1.06

=$12.50

Last year's price was $12.50.

Step-by-step explanation:

the text that is formatted in bold and underlined fonts are the answers to the missing (blank) terms in the given problem.

Given that  \(\huge\sf{\overline{AB}}\) is a straight line, and that ∠AOE, ∠EOF, and ∠FOB share a common vertex, at point O, whose sum equals 180°.  

1. Statement:  m∠AOB = 180°

  Reason: Definition of a straight angle.

2. Statement:  m∠AOE + m∠EOF + m∠FOB = m∠AOB

   Reason: Angle Addition Postulate.

3. Statement:  x + (2x + 34) + 20° = 180°

   Reason: Substitution.

4. Statement:  x = 42°

   Reason: Algebra.

1)   Straight angles have a measure of 180°.

2)  The Angle Addition Postulate states that if O is in the interior of ∠AOB, then it means that the measure if ∠AOB is equal to the sum of the measures of ∠AOE, ∠EOF, and ∠FOB. In other words:

           ⇒   \(\huge\bf\sf{m\angle{AOB}\:=m\angle{AOE}\:+m\angle{EOF}\:+m\angle{FOB}}\)

3) and 4) Since the ∠AOB is a straight angle, then it means that the sum of the measures of ∠AOE, ∠EOF, and ∠FOB equal the measure of ∠AOB = 180°. Hence, in order to solve for the value of x, simply add the given values for each angle:

x° + (2x + 34)° + 20° = 180°

x° + 2x° + 34° + 20° = 180°

Combine like terms:

3x° + 54° = 180°

Subtract 54° from both sides:

3x° + 54° - 54° = 180° - 54°

3x° = 126°

Divide both sides by 3 to solve for x:

\(\huge\sf{\frac{3x^\circ}{3}\:=\:\frac{126^\circ}{3}}\)

x = 42°

The top face (BCD) and the front face (EHD) both contain the line segment AD.

Downsizing refers to the process of reducing the size and workforce of a company to cut costs, increase efficiency, or adapt to changing market conditions. It involves eliminating positions, reducing staff numbers, or even closing down certain business units or branches.

Downsizing can occur for various reasons, such as financial difficulties, mergers and acquisitions, technological advancements, or strategic reorganization. Companies often assess their operational costs and decide to downsize to improve their financial performance.

During the downsizing process, companies may calculate the potential cost savings by considering factors such as salaries, benefits, severance packages, and operational expenses. For example, if a company decides to eliminate 100 positions with an average salary of $50,000 per year, it could result in annual savings of $5 million.

While downsizing can help companies achieve short-term cost reductions, it often has significant implications for the affected employees, including layoffs, reduced morale, and increased workload for remaining staff. It is crucial for organizations to handle the downsizing process with sensitivity and transparency, providing support to affected employees and communicating the rationale behind the decisions.

It is important to note that downsizing should not be seen as a long-term solution, but rather as a strategic measure to address specific challenges. Companies should also explore alternatives to downsizing, such as retraining and redeploying employees, implementing productivity improvements, or seeking new business opportunities, to ensure sustainable growth and success in the long run.

Answer:

Step-by-step explanation:inconclusive

the optimal values of O, 6, and ik to maximize the lower bound are O = (Yk1*x1 + Yk2*x2)/(Yk1+Yk2), 6 = (Yk1*hatmu_k1 + Yk2*hatmu_k2)/(Yk1+Yk2), and ik = Yk1/(Yk1+Yk2), where Yk1 and Yk2 are the probabilities of y=k given x1 and x2  

The question is asking for the optimal values of O, 6, and ik to maximize the lower bound, given that p(y=k|x,60) is fixed. We are given two data points x1 and x2, and we define Yki as the probability of y=k given xi, for i=1,2.

To find the optimal O, we can use the formula for the lower bound and take the derivative with respect to O, then set it to zero and solve for O. This gives us O = (Yk1*x1 + Yk2*x2)/(Yk1+Yk2).

To find the optimal 6, we can similarly take the derivative of the lower bound with respect to 6, set it to zero, and solve for 6. This gives us 6 = (Yk1*hatmu_k1 + Yk2*hatmu_k2)/(Yk1+Yk2), where hatmu_k is the expected value of x given y=k.

Finally, to find the optimal ik, we can use the constraint that i1+i2=1 and the formula for the lower bound. We take the derivative of the lower bound with respect to ik, set it to zero, and solve for ik in terms of Yk1 and Yk2. This gives us ik = Yk1/(Yk1+Yk2).

Therefore, the optimal values of O, 6, and ik to maximize the lower bound are O = (Yk1*x1 + Yk2*x2)/(Yk1+Yk2), 6 = (Yk1*hatmu_k1 + Yk2*hatmu_k2)/(Yk1+Yk2), and ik = Yk1/(Yk1+Yk2), where Yk1 and Yk2 are the probabilities of y=k given x1 and x2, and hatmu_k1 and hatmu_k2 are the expected values of x given y=k for each data  point.

Answer:

x=35

Step-by-step explanation:

So the line XYZ is 180. The angles together should equal 180 in total.

The equation would be (2x-5) + (3x+10) = 180.

2x-5+3x+10=180

You want to combine like terms.

2x+3x and -5+10

5x+5=180

subtract 5 from both sides. Need variable alone.

5x+5(-5)=180(-5)

5-5 is 0 and 180-5 is 175

5x=175

Divide by 5 on both sides.

5x/5=175/5

x=35

Answer:

x=35

Step-by-step explanation:

Angles on a straight line=180

therefore,(2x-5)+(3x+10)=180

2x-5+3x+10=180

collecting like terms we have,

2x+3x-5+10=180

5x+5=180

subtract 5 from both sides

5x+5-5=180-5

5x=175

divide both sides by coefficient of x

5x/5=175/5

x=35

Therefore, the surface represented by the given equation is a sphere centered at the origin with a radius of 6 units.

The given equation rho^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36 represents a surface in spherical coordinates. Let's break down the equation to identify the surface:

ρ^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36

Here, ρ represents the radial distance, φ is the polar angle, and θ is the azimuthal angle.

By analyzing the equation, we can see that it combines both the azimuthal and polar angles. The terms sin^2(φ)sin^2(θ) and cos^2(φ) involve both angles.

The equation ρ^2(sin^2(φ)sin^2(θ) + cos^2(φ)) = 36 describes a sphere centered at the origin with a radius of 6 units. The constant value of 36 indicates that the squared radial distance from the origin to any point on the surface is 36.
