Answer:

-1 and 4/3

Step-by-step explanation:

So first we want to find the equation for the linear function g(x):

We know that it is linear, so it will follow the equation

y = mx + b

m is the slope, and b is the y-intercept

First, find the slope:

We can see that every time the x increases by 1, the output value is increased by 2

This means that the slope will be 2

Then, find the y-intercept:

The y-intercept is when the x value is equal to 0, so in this table, when the x value is 0, the output is 7

So putting these number into the equation will give us:

y = 2x + 7

Now to find the solutions:

You have to set these equations equal to each other and solve for x

The set up should look like this:

\(3x^{2} + x +3 = 2x+7\)

Put all of the values on one side:

\(3x^{2} -x-4 = 0\)

And then solve for x by factoring:

\(3x^{2} +3x-4x-4\) = 0

\((3x^{2} +3x)+(-4x-4)\) = 0

\(3x(x+1)-4(x+1)\) = 0

(x+1)(3x-4) = 0

Finally, to get the x values:

x + 1 = 0

x = -1

and

3x - 4 = 0

3x = 4

x = 4/3

So the answers are:

x = -1 and 4/3

The solution to the system of equations that includes quadratic function f(x) and linear function g(x) is (-1,5) and (4/3,29/3).

A polynomial function is a relation where a dependent variable is equal to a  polynomial expression. A polynomial expression is an expression including numbers and variables, where variables are raised to non-negative powers.

The general form of a polynomial expression is:

a₀ + a₁x + a₂x² + a₃x³ + ... + aₙxⁿ.

The highest power to a variable is the degree of the polynomial expression.

When degree = 2, the function is a quadratic function.

When degree = 1, the function is a linear function.

The quadratic function is given to us:

f(x) = 3x² + x + 3.

We need to determine the linear equation g(x). Since it's a linear equation we use the two-point method to determine the equation.

The two-point formula is:

y-y₁ = ((y₂-y₁)/(x₂-x₁))*(x-x₁)

We take the points g(2) = 11, g(1) = 9

g(x) - g(1) = ((g(2)-g(1))/(2-1))*(x-1)

or, g(x) - 9 = ((11-9)/(2-1))*(x-1)

or, g(x) - 9 = 2(x-1)

or, g(x) = 2x - 2 + 9 = 2x + 7

∴ g(x) = 2x +7, is the linear function g(x)

We are asked to find the solution to the system of equations f(x) and g(x).

To find the solution we need to check what is the common solution to both f(x) and g(x).

For that, we equate f(x) and g(x).

3x² + x + 3 = 2x + 7

or, 3x² - x - 4 = 0

or, 3x² + 3x - 4x - 4 = 0

or, 3x(x+1) -4(x+1) = 0

or, (3x-4)(x+1) = 0

∴ Either 3x-4=0 ⇒ x = 4/3

or, x+1=0 ⇒ x = -1.

g(-1) = 5 (from the table)

f(-1) = 3(-1)² + (-1) + 3 = 3 - 1 + 3 = 5

g(4/3) = 2(4/3) + 7 = 8/3 + 21/3 = 29/3

f(4/3) = 3*(4/3)² + (4/3) + 3 = 16/3 + 4/3 + 9/3 = 29/3

∴ f(-1) = g(-1) and f(4/3) = g(4/3), so

The solution to the system of equations that includes quadratic function f(x) and linear function g(x) is (-1,5) and (4/3,29/3).

The exponential smoothing forecast for period 5, assuming alpha is 0.5, is 416 (rounded to two decimal places).

Exponential smoothing is a forecasting method that uses a weighted average of past observations, with more recent observations receiving higher weights. The forecast for a specific period is calculated by adding the weighted average of the previous period's forecast and the actual observation.

Given the data and alpha value provided, we can calculate the exponential smoothing forecast for period 5 using the following steps:

1. Initialize the forecast for period 1 as the actual observation for period 1: F1 = 418.

2. Calculate the forecast for period 2 using the exponential smoothing formula:

  Ft = α * At-1 + (1 - α) * Ft-1

  Where:

  Ft = Forecast for period t

  At-1 = Actual observation for period t-1

  Ft-1 = Forecast for period t-1

  α = Smoothing parameter (alpha)

  Using the values provided, we can calculate F2:

  F2 = 0.5 * 418 + (1 - 0.5) * 418 = 418

3. Repeat the calculation for periods 3, 4, and 5:

  F3 = 0.5 * 412 + (1 - 0.5) * 418 = 415

  F4 = 0.5 * 413 + (1 - 0.5) * 415 = 414

  F5 = 0.5 * 418 + (1 - 0.5) * 414 = 416

Therefore, the exponential smoothing forecast for period 5, assuming alpha is 0.5, is 416 (rounded to two decimal places).

Answer:

100/360 * 2\(\pi\)5

1000\(\pi\)/360 = 25\(\pi\)/9 = 8.722

Step-by-step explanation:

The equation of the function is f(x) = x(x + 2)(x -1)(x -3)

From the graph, we have the following highlight:

The above means that:

f(x) approaches positive infinity irrespective of the x value

Hence, the end behavior of the function is:

\(\mathrm{as}\:x\to \:+\infty \:,\:f\left(x\right)\to \:+\infty \:,\:\:\mathrm{and\:as}\:x\to \:-\infty \:,\:f\left(x\right)\to \:+\infty \:\)

Since, the function opens upward.

Then the sign of the leading coefficient is positive

This is the point, where the graph crosses the x-axis.

From the graph, we have the zeros to be:

x = -2, x = 0, x = 1 and x = 3

Since the graph crosses the x-axis at this point, then the multiplicity of the zeros is 1

In (c), we have:

x = -2, x = 0, x = 1 and x = 3

Rewrite as:

x + 2= 0, x = 0, x - 1 = 0 and x - 3 = 0

Multiply these values

f(x) = x(x + 2)(x -1)(x -3)

Hence, the equation of the function is f(x) = x(x + 2)(x -1)(x -3)

Answer: => 56.52 cm²

Step-by-step explanation:

To find the one-sided limit of the function f(x) = (x-9)² as x approaches 9 from the left (x → 9-), we need to evaluate the expression (-9)². The result of this calculation is 81, indicating that the one-sided limit of f(x) as x approaches 9 from the left is 81.

The expression (-9)² simplifies to 81. This means that as x approaches 9 from the left (x → 9-), the function f(x) = (x-9)² approaches the value 81. Therefore, the one-sided limit of f(x) as x approaches 9 from the left is 81.

It's important to note that this result is specific to the left-hand side limit.

To find the two-sided limit (if it exists), we would need to evaluate the limit as x approaches 9 from both the left and the right and ensure that the values match.

In this PE class with 48 students, one group of 24 students decides to play volleyball, leaving 24 students who will be shooting baskets. The teacher then divides the remaining 24 students into as many groups of 5 as possible, which results in 4 groups. Each group will have 5 students, and one student will be left without a group.

In this scenario, there are 48 students in the PE class. One group of 24 students chooses to play volleyball, leaving 24 students (48 - 24 = 24) remaining. The teacher then divides the remaining students into as many groups of 5 as possible to shoot baskets.

To determine how many groups of 5 can be formed, we'll divide the remaining students by 5:
24 ÷ 5 = 4 (with a remainder of 4)

So, the teacher can create 4 groups of 5 students each for shooting baskets. This accounts for 20 students (4 groups x 5 students = 20).

Since there were 24 students remaining after the volleyball group, and 20 of those students have been assigned to basketball groups, we're left with 4 students (24 - 20 = 4) who will climb the rock wall.

The key difference between observational studies and experimental designs is that a well-done observational study does not influence the responses of participants, while experiments do have some sort of treatment condition applied to at least some participants by random assignment.

An observational study is used in fields such as epidemiology, social sciences, psychology, and statistics to draw conclusions from a sample to a population where the independent variable is not under the researcher's control due to ethical concerns or logistical constraints.

Observational studies involve the study of participants who have had no forced change in their circumstances, i.e., no intervention.

Although participants' behavior may change while being observed, the goal of observational studies is to look into the 'natural' state of risk factors, diseases, or outcomes.

Observational studies are those in which researchers examine the impact of a risk factor, diagnostic test, treatment, or other intervention without attempting to change who is or is not exposed to it.

Answer:

12 ft for the actual length of the room

9ft for the actual width of the room

42 ft for the actual perimeter of the room

Step-by-step explanation:

Scale is:

1 foot = 3/4 inch

1 inch = 1: 3/4 foot = 4/3 foot

a. The length of the room

9 inches = 9*4/3 foot = 12 ft in the length of the room

b. The width of the room

6 3/4 inches = 27/4 inches = 27/4*4/3 = 9 ft in the width of the room

a. (width+ length) * 2

b. (9+12) *2

42 ft in perimeter of the room

Answer:

Step-by-step explanation:

1.

To find the actual length of the room, we need to convert the length on the drawing from inches to feet. Since each foot is represented by 3/4 inch, we can set up the proportion:

9 inches / (3/4 inch per foot) = x feet

Simplifying the right side of the equation, we get:

9 inches / (3/4 inch per foot) = 12 feet

Therefore, the actual length of the room is 12 feet.

2.

To find the actual width of the room, we need to follow the same process as above. Since the width on the drawing is 6 3/4 inches, we have:

6 3/4 inches / (3/4 inch per foot) = x feet

Simplifying the right side of the equation, we get:

6 3/4 inches / (3/4 inch per foot) = 9 feet

Therefore, the actual width of the room is 9 feet.

3.

To find the actual perimeter of the room, we need to add up the lengths of all four sides. Since the length is 12 feet and the width is 9 feet, we have:

Perimeter = 2(Length) + 2(Width)

Perimeter = 2(12 feet) + 2(9 feet)

Perimeter = 24 feet + 18 feet

Perimeter = 42 feet

Therefore, the actual perimeter of the room is 42 feet.

The angles measure 21 degrees and 69 degrees.

Step-by-step explanation:

Complementary angles have a sum of 90 degrees when added together.

Let's call the complementary angle x. We can write the angle that we're looking for as in terms of x as x + 48.

Since these angles must sum to 90 we can write the equation and solve:

x + x + 48 = 90

2x + 48 = 90

2x + 48 - 48 = 90 - 48

2x = 42

x = 21

x + 48 = 69

21 degrees and 69 degrees.

Answer:

69° and 21° is the answer.
