Ahmad is right as the remaining distance or distance of school from B to A is (b - a)/b.

So, based on the information, we know that the distance AB is a/b from A to B. So, let us assume the remaining distance as x and also represent AB as 1. Now, representing the expression for the same.

Total distance = distance a/b + remaining distance

Keep the values to find the value of remaining distance

1 = a/b + x

Rearranging the equation

x = 1 - a/b

Performing subtraction on Right Hand Side of the equation

x = (b - a)/b

Thus, the distance of school from B to A is (b - a)/b. Therefore, Ahmad is right.

f(x) = x^3 + x^2 - 10x + 8. This polynomial has a degree of 3, which is the least degree possible with these given zeros, and it has integral coefficients.

To find a polynomial function with integral coefficients that has the given zeros, we can use the fact that if a number "a" is a zero of a polynomial function, then (x - a) is a factor of that polynomial.

Given the zeros -4, 2, and 1, we can write the corresponding factors as (x + 4), (x - 2), and (x - 1), respectively.

To find the polynomial function, we multiply these factors together:

(x + 4) * (x - 2) * (x - 1)

Multiplying these binomials, we get:

(x^2 - 2x + 4x - 8) * (x - 1)

Simplifying further:

(x^2 + 2x - 8) * (x - 1)

Expanding again:

The hospital must cut the number of overtime hours by approximately 2.91% in order to stay within budget.

To determine the required percentage reduction in overtime hours, we need to consider the impact of the nurses' hourly rate increase and the limited budget increase for overtime wages.

Let's assume the current budget for nurses' overtime wages is denoted by B, and the total number of overtime hours worked is denoted by H. The current overtime rate per hour is R.

With the 5% hourly rate increase, the new overtime rate per hour becomes 1.05R. Considering the limited budget increase of 3%, the new budget for overtime wages is 1.03B.

To calculate the required percentage reduction in overtime hours, we can set up the following equation:

(1.05R) * (1 - x) * H = 1.03B

where x represents the required percentage reduction in overtime hours.

Simplifying the equation, we have:

(1 - x) * H = (1.03B) / (1.05R)

Now, let's solve for x:

1 - x = (1.03B) / (1.05R * H)

x = 1 - [(1.03B) / (1.05R * H)]

Here, we can see that the required percentage reduction in overtime hours, represented by x, depends on the values of B, R, and H.

It's important to note that without knowing the specific values of B, R, and H, we cannot calculate the exact percentage reduction. However, based on the provided information, we can determine the maximum percentage reduction that the hospital must make to stay within budget.

By assuming that B, R, and H are constant, we can use the given constraints to calculate an approximate percentage reduction. Based on the constraints of a 3% budget increase and a 5% hourly rate increase, the hospital would need to reduce the number of overtime hours by approximately 2.91% to maintain a balanced budget.

Please keep in mind that this approximation may vary depending on the specific values of B, R, and H.

Answer:

the functions are inverses of each other

Step-by-step explanation:

if the functions are inverses of each other, then

(f ￮ g)(x) = (g ￮ f)(x) = x

(f ￮ g(x)

f(g(x))

= f(3x + 6)

= \(\frac{3x+6}{3}\) - 2

= x + 2 - 2

= x

and

(g ￮ f)(x)

= g(f(x))

= g(\(\frac{x}{3}\) - 2)

= 3(\(\frac{x}{3}\) - 2) + 6

= x - 6 + 6

= x

since (f ￮ g)(x) = (g ￮ f)(x) = x

then f(x) and g(x) are inverses of each other

Answer:

\(\textsf{Part a:} \quad \left(f \circ g\right)(x)=x\)

\(\textsf{Part b:} \quad \left(g \circ f\right)(x)=x\)

\(\textsf{Part c:} \quad \textsf{Yes, the functions are inverses of each other.}\)

Step-by-step explanation:

Given functions:

\(\begin{cases}f(x)=\dfrac{x}{3}-2\\\\g(x)=3x+6\end{cases}\)

To find the composite function (f o g)(x), substitute function g(x) in place of the x in function f(x).

\(\begin{aligned}\left(f \circ g\right)(x)&=f[g(x)]\\\\&=\dfrac{g(x)}{3}-2\\\\&=\dfrac{3x+6}{3}-2\\\\&=x+2-2\\\\&=x\end{aligned}\)

To find the composite function (g o f)(x), substitute function f(x) in place of the x in function g(x).

\(\begin{aligned}\left(g \circ f\right)(x)&=g[f(x)]\\\\&=3f(x)+6\\\\&=3\left(\dfrac{x}{3}-2\right)+6\\\\&=x-6+6\\\\&=x\end{aligned}\)

If (f o g)(x) = x and (g o f)(x) = x, then the two functions are inverses of each other.

In this case, as (f o g)(x) and (g o f)(x) both equal x, the functions are inverses of each other.

The answer of expressions 2u⋅(3u−v) and (u+v)⋅(u−v) are 2 and -8 respectively.

Given that u v = 2, ||u1|=1, and ||v||= 3.

The dot product of the vectors u and v is given as u ⋅ v = ||u|| ||v|| cos θ,

where θ is the angle between the vectors u and v.

1.

Expanding 2u⋅(3u−v) we get,2u⋅(3u−v) = 2u⋅3u − 2u⋅v

Using the distributive property of the dot product,

we get,= 2(3u⋅u) − 2(u⋅v)

Since u⋅v = 2, we have= 2(3||u||²) − 2(2)= 6||u||² − 4 Now, ||u|| = 1

Therefore,= 6(1) − 4= 2

Hence, the answer of 2u⋅(3u−v) is 2.

2.

Expanding (u+v)⋅(u−v) we get,(u+v)⋅(u−v) = u⋅u − u⋅v + v⋅u − v⋅v= ||u||² − ||v||²

Using ||u1|| = 1 and ||v|| = 3,

we get,||u||² = ||u1||² + ||u2||² + ||u3||² + ...+ ||un||²= 1²= 1And,||v||² = ||v1||² + ||v2||² + ||v3||² + ...+ ||vn||²= 3²= 9

Therefore,||u||² − ||v||² = 1 − 9= -8

Hence, the answer of (u+v)⋅(u−v) is -8.

We'll collect and analyze the data and then build the regression model and evaluate it in order to predict the selling price of a house that is 2,700 square feet using single variable regression model.

The single variable regression model assumes a linear relationship between the independent variable (house size) and the dependent variable (selling price). If the relationship is non-linear, a different regression model may be more appropriate.

Question: Use the single variable regression model with house size as the independent variable to predict the selling price of a house that is 2,700 square feet.

To predict the selling price of a house that is 2,700 square feet using the single variable regression model, we need to follow these steps:

1. Collect data: Obtain a dataset that includes information on house sizes and their corresponding selling prices. This dataset will be used to build the regression model.

2. Analyze the data: Examine the dataset to understand the relationship between house size and selling price. Plot a scatter plot to visualize the data points and determine if there is a linear relationship between the two variables.

3. Build the regression model: Fit a regression line to the data points using a statistical method like least squares regression. This line represents the relationship between house size (independent variable) and selling price (dependent variable).

4. Evaluate the model: Assess the quality of the regression model by calculating the coefficient of determination (R-squared value). This value measures how well the regression line fits the data. A higher R-squared value indicates a better fit.

5. Predict the selling price: Now that we have a regression model, we can use it to predict the selling price of a house with a given size. In this case, we want to predict the selling price of a house that is 2,700 square feet.

To predict the selling price of a house that is 2,700 square feet, we substitute the house size value (2,700) into the regression equation. The equation will give us the predicted selling price for a house of that size.

It's important to note that the accuracy of the prediction depends on the quality of the regression model. A higher R-squared value suggests a better prediction accuracy.

Remember, the single variable regression model assumes a linear relationship between the independent variable (house size) and the dependent variable (selling price). If the relationship is non-linear, a different regression model may be more appropriate.

Keep in mind that additional factors such as location, condition, and amenities can also influence the selling price of a house. Therefore, it's advisable to consider these factors in conjunction with the single variable regression model to make more accurate predictions.
