What can you conclude about the slope of the values in the table? Check all that apply.
The slope is 3.
The slope is 0.
The slope is undefined.
The graph will be a horizontal line.
The graph will be a vertical line.
The graph will have a line with a positive slope.
The conclusion that can be drawn from the slope of the values given in the table is:
3. Slope is undefined.
5. Graph is a vertical line.
First, let's determine the value of the slope by applying the slope formula using two points given from the table, say, (1000, 20) and (1000, 23):Slope formula = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let,[tex](1000, 20) = (x_1, y_1)\\\\(1000, 23) = (x_2, y_2)[/tex]
Substitute:[tex]slope(m)=\frac{23 - 20}{1,000 - 1,000}\\\\slope (m) =\frac{3}{0}[/tex] (undefined)
Zero cannot divide 3 hence, the slope is undefined.Slope that are vertical have rise but no run, thus, their slope is undefined.(see attachment for image showing an example of how an undefined slope looks like on a graph.)
Therefore, the conclusion that can be drawn from the slope of values given in the table is:
3. Slope is undefined.
5. Graph is a vertical line.

Answer:
The expression (7x − 3) × (4x² − 3x − 6) is equivalent to 28x³ - 33x² - 33x + 18 .
Step-by-step explanation:
As given the expression in the question be as follow .

To solve the problem we must know about density.
The different weight shows that the solids have different density.
Given to us
A cubic centimeter of quartz, olivine, and gold weighs 2.5, 3.0, and 19.8 grams.What are weight and mass?We know that weight is the product of mass and acceleration due to gravity, also, mass is the product of density and volume.
[tex]\rm{ weight = mass \times acceleration\ due\ to\ gravity[/tex]
[tex]\rm{ w = m \times g[/tex]
[tex]\rm{ Mass = density \times volume[/tex]
[tex]m = \rho \times v[/tex]
What is the relationship between weight and mass?In the three solids given, the acceleration due to gravity will be the same, also, it is already mentioned that the volume of the three materials is the same that is 1 cubic centimeter.
[tex]w = m \times g\\w = (\rho \times v) \times g\\\\w = \rho \times 1\ cm^3 \times 9.81[/tex]
Therefore, the only thing that can vary is the density of the solids. Hence, the different weight shows that the solids have different density, the more is the weight the more is the density of the solid.

,
,
The recursive formula an = an – 1 + an – 2 describes a sequence where each term is the sum of the two previous terms. To find the first five or six terms, we substitute the given initial conditions into the formula and repeatedly apply it to find subsequent terms.
Explanation:The recursive formula an = an – 1 + an – 2 describes a sequence where each term is the sum of the two previous terms. To find the first five terms, we begin with a1 = 1.2 and a2 = 2.3. Then we use the formula to find the next terms:
a3 = a2 + a1 = 2.3 + 1.2 = 3.5a4 = a3 + a2 = 3.5 + 2.3 = 5.8a5 = a4 + a3 = 5.8 + 3.5 = 9.3So the first five terms of the sequence are 1.2, 2.3, 3.5, 5.8, and 9.3.
Similarly, to find the first six terms of the sequence with a3 = -5 and a4 = 3, we use the formula:
a5 = a4 + a3 = 3 + (-5) = -2a6 = a5 + a4 = -2 + 3 = 1So the first six terms of this sequence are -5, 3, -2, 1, -1, and 0.

For what values of x does f(x)= x^2 +9x +20 reach its minimum value?
The minimum value of the quadratic function f(x)= [tex]x^2[/tex] +9x +20 is achieved at x = -4.5, calculated using the vertex formula -b/2a.
Explanation:The function f(x)= [tex]x^2[/tex] +9x +20 is a quadratic function. The minimum value of a quadratic function is achieved at the vertex. The x-coordinate of the vertex can be found using the formula -b/2a, where a and b are coefficients of [tex]x^2[/tex] and x respectively in the standard form a[tex]x^2[/tex] + bx + c. Here, a=1 and b=9.
So, by applying the formula, the value of x will be -b/2a = -9/(2*1) = -4.5. Hence, the function achieves its minimum value when x = -4.5.

How many zeros are there at the end of 100!?
Final answer:
The number of zeros at the end of 100! is determined by counting the multiples of 5 in the factorization, including higher powers like 25. The result is a total of 24 zeros at the end of 100!.
Explanation:
To determine how many zeros are at the end of the factorial of 100 (100!), we need to know how many times the number 10 can be factored within that number. Since 10 is the product of 2 and 5, we should count the number of 2s and 5s in the prime factorization of 100!. The number of zeros at the end of 100! will equal the smaller of these two counts. However, because there are more 2s than 5s in the prime factorization, we only need to count the number of 5s as every 5 will have a corresponding 2 to form a 10.
For 100!, we count how many multiples of 5 there are within that range, including the multiples of 25 (since 25 includes an extra 5), and possibly higher powers of 5 if applicable. For example, 5 is counted once, 25 is counted twice (as 25 = 5×5), and so on.
Therefore, the number of zeros at the end of 100! equals the sum of the integer division of 100 by 5, plus the integer division of 100 by 25, and so on for any higher powers of 5. However, since 100 < 125, we do not need to consider any higher powers than 25.
We calculate:
100 ÷ 5 = 20,
100 ÷ 25 = 4.
Adding these together (20 + 4), we find that there are 24 zeros at the end of 100!.

If you were asked to load 225 boxes onto a truck, and the boxes are crated with each crate containing nine boxes, how many crates would you need to load
Answer:
You should load 25 crates onto a truck.
Step-by-step explanation:
Given:
There are 225 boxes.
Each crate containing 9 boxes.
We need to find the number of crates that containing 225 boxes.
Here we use division to find the answer.
Number of crates = Total number of boxes / Number of boxes in each crate
= 225/9
= 25
You should load 25 crates onto a truck.
