Kuta Software - Infinite Algebra 1 is an educational tool that focuses on providing students with algebra 1 exercises. The software includes a range of topics that cover the fundamentals of algebra 1. One of the topics that the software covers is Adding and Subtracting Polynomials. Adding Polynomials involves combining like terms.

In the case where the polynomials are in descending order, students can start adding or subtracting their respective terms. Similarly, if the polynomials are in ascending order, the students should start with the terms with the highest degree and work their way down. Adding polynomials is relatively easy since it involves combining like terms.

However, when it comes to subtracting polynomials, the process becomes a bit more complicated. The subtraction of polynomials involves changing the sign of the terms to be subtracted. To be able to do this, students can first distribute a negative sign throughout the polynomial, then follow the same procedure they would have followed when adding polynomials to combine like terms.

Answer:

The correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].

Step-by-step explanation:

We know that the opposite of the opposite of a number, say 2, is the number itself.

That is:

Opposite of 2 is -2.

Then the opposite of -2 is:

- (-2) = 2

It is provided that:

Assume that both Justine and Meagan started with 0 score.

Justine plays first.

If Justine answered a question incorrectly, his score would be -7.

Then Meagan plays, and answers the question correctly.

So, Meagan got the opposite score.

The opposite of -7 will be [- (-7)].

Thus, the correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].

The length of the rectangle is 6 feet and the width is 4 feet.

The given information states that the perimeter of the rectangle is 20 feet and the area is 24 square feet. To find the length and width, we can use the formulas for perimeter and area of a rectangle.

Let's start by finding the perimeter. The formula for the perimeter of a rectangle is P = 2(l + w), where P represents the perimeter, l represents the length, and w represents the width. In this case, the perimeter is given as 20 feet. Plugging in the values, we have 20 = 2(l + w).

Now, let's find the area of the rectangle. The formula for the area of a rectangle is A = l * w, where A represents the area. In this case, the area is given as 24 square feet. So we have 24 = l * w.

To solve these equations simultaneously, we can use substitution or elimination. Let's rearrange the perimeter equation to express one variable in terms of the other. From 20 = 2(l + w), we can simplify to l + w = 10, and thus, l = 10 - w.

Now substitute the value of l in the area equation: 24 = (10 - w) * w. Simplifying further, we have 24 = 10w - w^2.

Rearranging the equation to the quadratic form, we get w^2 - 10w + 24 = 0. Factoring this equation, we have (w - 4)(w - 6) = 0.

Setting each factor equal to zero, we find two possible values for the width: w = 4 and w = 6. Plugging these values back into the perimeter equation, we find the corresponding lengths: l = 6 and l = 4.

Therefore, the dimensions of the rectangle are length = 6 feet and width = 4 feet.

Step-by-step explanation:

Answer: If a1 = 16 and a2 = -8, then we can write a recursive formula for the nth term of the sequence as follows:

an = a(n-1)/2

This formula states that the nth term of the sequence is equal to the previous term (n-1) divided by 2. For example, if n = 3, then a3 = a(3-1)/2 = a2/-8/2 = 4.

We can also write this formula in terms of the initial values of the sequence as follows:

a(n) = (-1)^(n-1) * 8

This formula states that the nth term of the sequence is equal to (-1) raised to the power of (n-1), multiplied by 8. This formula will always give the correct value for the nth term of the sequence, regardless of the initial values of the sequence.

Different logs measure different physical properties of the formation that are related to porosity, and the relationship between the log measurement and porosity can be expressed through equations.

The different logs used to obtain porosity and their principles of measurement, quantities measured, and relation to porosity.
There are three main types of logs used to obtain porosity: neutron logs, density logs, and sonic logs.
Neutron logs: These logs measure the hydrogen content in a formation, which is directly related to porosity. The tool emits neutrons that interact with hydrogen atoms, and the resulting gamma rays are measured. The count rate decreases with increasing porosity. The neutron log can be expressed as:
Porosity = (neutron log reading - matrix reading) / (fluid reading - matrix reading)
Density logs: Density logs measure the bulk density of a formation, which can be related to porosity. The tool emits gamma rays that interact with the formation, and the scattered gamma rays are measured. The bulk density decreases with increasing porosity. The density log can be expressed as:
Porosity = (matrix density - bulk density) / (matrix density - fluid density)
Sonic logs: Sonic logs measure the travel time of sound waves through a formation, which can be related to porosity. The tool sends an acoustic wave and measures the time it takes to travel a specific distance. The travel time increases with increasing porosity. The sonic log can be expressed using Wyllie's time-average equation:
Porosity = (sonic log reading - matrix reading) / (fluid reading - matrix reading)
In summary, neutron logs measure hydrogen content, density logs measure bulk density, and sonic logs measure travel time of sound waves. These measurements can be used to calculate porosity using the respective equations provided.

If the treatment has no effect, then the mean of the sample is expected to remain the same as the population mean of µ = 100,  Therefore, the treatment would not change the expected value of the population.

If a sample of n = 30 individuals is selected from a population with µ = 100, and a treatment is administered to the sample, the expectation if the treatment has no effect would be as follows:
1. The sample mean (M) would be close to the population mean (µ).
2. The treatment would not cause any significant change in the sample's characteristics compared to the population.
3. The sample mean (M) would still be around 100 after the treatment is administered, since the treatment does not impact the population's characteristics.
In summary, if the treatment has no effect, the sample mean should remain close to the population mean (µ = 100) after the treatment is administered.

Let A be the set of people who speak English.    

B be the set of people who speak French.  

A - B be the set of people who speak English and not French.  

B - A be the set of people who speak French and not English.  

A ∩ B be the set of people who speak both French and English.  

Given

n(A) = 72       n(B) = 43       n(A ∪ B) = 100  

Now, n(A ∩ B) = n(A) + n(B) - n(A ∪ B)  

 = 72 + 43 - 100  

= 72 + 43 - 100  

= 115 - 100  

= 15

Therefore, Number of persons who speak both French and English

= 15  

n(A) = n(A - B) + n(A ∩ B)  

⇒ n(A - B) = n(A) - n(A ∩ B)  

= 72 - 15  

= 57

and n(B - A) = n(B) - n(A ∩ B)  

 = 43 - 15 = 28  

Therefore, Number of people speaking English only = 57  

Number of people speaking French only = 28

Let A be the set of people who speak English.    

B be the set of people who speak French.  

A - B be the set of people who speak English and not French.  

B - A be the set of people who speak French and not English.  

A ∩ B be the set of people who speak both French and English.  

Given

n(A) = 72       n(B) = 43       n(A ∪ B) = 100  

Now, n(A ∩ B) = n(A) + n(B) - n(A ∪ B)  

= 72 + 43 - 100  

= 72 + 43 - 100  

= 115 - 100  

= 15

Therefore, Number of persons who speak both French and English

= 15  

n(A) = n(A - B) + n(A ∩ B)  

⇒ n(A - B) = n(A) - n(A ∩ B)  

= 72 - 15  

= 57

and n(B - A) = n(B) - n(A ∩ B)  

= 43 - 15 = 28

Answer:

The answer is below

Step-by-step explanation:

Let x represent the length of the rectangular pen and y represent the width of the rectangular pen. Since the total area of the pen is 169 ft², hence:

Area = length * width

169 = xy

y = 169/x

Also the perimeter of the rectangular pen is:

Perimeter (P) = 2(length + width)

P = 2(x + y)

P = 2x + 2y

P = 2x + 2(169/x)

P = 2x + 338/x

The least amount of fencing is at dP/dx = 0, hence:

dP/dx = 2 - 338/x² = 0

338/x² = 2

2x² = 338

x² = 169

x = 13 feet

y = 169 / x = 169/13 = 13 feet

The least amount of fencing = P = 2(x + y) =  2(13 + 13) = 52 feet

The value of the integral

∫ d t ( 1 − 3 t ) 5 = (-1/243)(1-3t)⁶/6 + (5/81)(1-3t)⁵/15 - (10/36)(1-3t)⁴/36 + (10/81)(1-3t)³/81 - (5/324)(1-3t)²/243 + c

To evaluate this integral using the given substitution, we need to first find an expression for dt in terms of du. To do this, we can differentiate the substitution equation u = 1 - 3t with respect to t, giving:

du/dt = -3

Solving for dt, we get:

dt = -du/3

Now we can substitute for dt and for 1-3t in the integral, giving:

∫ d t ( 1 − 3 t ) 5 = ∫ (1-u/3)⁵ (-du/3)

Expanding the binomial and factoring out the constant -1/243, we get:

∫ (u⁵ - 5u⁴/3 + 10u³/9 - 10u²/27 + 5u/81 - 1/243) du

Integrating each term separately, we get:

(u⁶/6 - 5u⁵/15 + 10u⁴/36 - 10u³/81 + 5u²/324 - u/243) + c

Substituting back for u, we get the final answer:

∫ d t ( 1 − 3 t ) 5 = (-1/243)(1-3t)⁶/6 + (5/81)(1-3t)⁵/15 - (10/36)(1-3t)⁴/36 + (10/81)(1-3t)³/81 - (5/324)(1-3t)²/243 + c

After solving we can observe that both equations give us the same value for the constant, which is 60. Therefore, the answer is (C) 60.

How solve equation with the help of graph ?

To solve an equation using a graph, you need to plot the points that satisfy the equation on a coordinate plane, and then find the intersection of the graph with the x- or y-axis.

To find the value of the constant in the equation Height = Constant/Width, we need to use the given data points on the graph. We know that:

When Width = 2, Height = 30

When Width = 5, Height = 12

When Width = 10, Height = 6

When Width = 30, Height = 2

Substituting these values into the equation, we get:

30 = Constant/2

12 = Constant/5

6 = Constant/10

2 = Constant/30

To solve for the constant, we can pick any two of the equations above and use them to eliminate the variable "Constant". Let's use the first and third equations:

30 = Constant/2 --> Constant = 60

6 = Constant/10 --> Constant = 60

As we can see, both equations give us the same value for the constant, which is 60. Therefore, the answer is (C) 60.
