Given the right triangle of the figure, we must compute the length of the sides AB and AC.
From the picture we read the following data about the triangle:
- we consider the angle
\(\theta=60^{\circ}\)- respect to the angle θ we see that the adjacent cathetus side is BC, and its length is:
\(BC=6\)- respect to the angle θ the opposite cathetus is AC
- the hypotenuse of the triangle is AB
We have the following trigonometric identities:
\(\begin{gathered} (1)\rightarrow\cos \theta=\frac{\text{adjacent cathetus}}{\text{hypotenuse}} \\ (2)\rightarrow\tan \theta=\frac{\text{opposite cathetus}}{\text{adjacent cathetus}} \end{gathered}\)1) Using equation (1) and the data above we compute the value of the hypotenuse AB:
\(\begin{gathered} \cos 60^{\circ}=\frac{6}{AB} \\ AB\cdot\cos 60^{\circ}=6 \\ AB=\frac{6}{\cos 60^{\circ}} \\ AB=\frac{6}{0.5}=12 \end{gathered}\)2) Using equation (2) and the data above we compute the value of the opposite cathetus AC:
\(\begin{gathered} \tan 60^{\circ}=\frac{AC}{6} \\ AC=\tan 60^{\circ}\cdot6 \\ AC=\sqrt[]{3}\cdot6 \end{gathered}\)Answers
AB = 12
AC = 6√3
Determine the largest power of 10 that is a factor of the following numbers (equivalently, the number of terminal 0's, using ordinary base 10 representation):(a) 50!.
(b) 1000!.
The largest power of 10 that is a factor of 1000! is 5^249, or 10^249.
(a) To find the largest power of 10 that is a factor of 50!, we need to count the number of factors of 5 in 50! since each factor of 5 contributes at least one factor of 10.
There are 10 multiples of 5 in 50!, namely 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50. Each of these contributes one factor of 5. There are also 2 multiples of 25 (25 and 50), each of which contributes an additional factor of 5. Therefore, the total number of factors of 5 in 50! is 10 + 2 = 12.
Since each factor of 10 contains one factor of 5 and one factor of 2, we also need to count the number of factors of 2. It is clear that there are more factors of 2 than factors of 5, so we only need to count the factors of 5. Therefore, the largest power of 10 that is a factor of 50! is 5^12, or 10^12.
(b) To find the largest power of 10 that is a factor of 1000!, we follow the same reasoning as in part (a). The number of factors of 5 in 1000! is:
⌊1000/5⌋ + ⌊1000/25⌋ + ⌊1000/125⌋ + ⌊1000/625⌋ = 200 + 40 + 8 + 1 = 249

Step-by-step explanation:
The relationship of horsepower of motorcycles to miles per gallon is represented by the following scatter plot:
Scatter plot with horsepower on the x axis and observed MPG on the y axis. The points plotted are 62 and 32, 63 and 31, 66 and 30, 71 and 30, 75 and 29, 81 and 27, 91 and 24, 94 and 25, 97 and 21, 99 and 20, 104 and 21, 114 and 18, 115 and 19, 120 and 17.
Jorge created the following residual plot:
Residual plot with x axis labeled horsepower and y axis labeled residuals. The points plotted are 62 and 0.44, 63 and negative 0.3, 66 and negative 0.52, 71 and 0.78, 75 and 0.82, 81 and 0.38, 91 and negative 0.02, 94 and 1.76, 97 and negative 1.46, 99 and negative 1.94, 104 and 0.36, 114 and negative 0.04, 115 and 1.22, 120 and 0.52.
Does his residual plot make sense based on the scatter plot? Explain.
A. The random residual plot makes sense because the scatter plot appears to have a linear relationship.
B. The random residual plot makes sense because the scatter plot appears to have a negative relationship.
C. The random residual plot does not make sense because it should have a linear relationship like the scatter plot.
D. The random residual plot does not make sense because it should have a nonlinear curve, as the scatter plot is negative.
Answer:
Step-by-step explanation:
Based on the information provided, the residual plot makes sense based on the scatter plot.
In the given scatter plot, the points are plotted with horsepower on the x-axis and observed MPG (miles per gallon) on the y-axis. The scatter plot shows the relationship between horsepower and MPG for the motorcycles.
The residual plot, on the other hand, shows the differences between the observed MPG values and the predicted MPG values based on the regression line or model. Residuals represent the vertical distances between the observed data points and the regression line.
Looking at the residual plot, we can see that the residuals are scattered randomly around the zero line. Some residuals are positive, while others are negative, indicating that the observed MPG values deviate both above and below the predicted MPG values.
Given this information, option A is the correct answer: "The random residual plot makes sense because the scatter plot appears to have a linear relationship." The scatter plot does not necessarily suggest a positive or negative relationship between horsepower and MPG. It simply shows the general trend or pattern. The random distribution of residuals in the residual plot indicates that the regression model is capturing the relationship adequately, and the variations or deviations from the regression line are random, which is expected in a good regression model.
The residual plot created by Jorge does make sense as it reflects the negative relationship between horsepower and miles per gallon present in the original scatter plot. As the horsepower increases, the miles per gallon decreases which is depicted accurately in the residual plot made.
Explanation:The best answer for this is B. The random residual plot makes sense because the scatter plot appears to have a negative relationship. A residual plot is a graph that is used to examine the goodness of fit in regression and ANOVA analysis. It is the differences between the observed and predicted values of data. The points in a residual plot are randomly dispersed around a horizontal axis if the corresponding regression model is appropriate for the data.
In this case, the scatter plot demonstrates a negative relationship between the horsepower of motorcycles and miles per gallon. As the horsepower increases, the miles per gallon decrease. This negative relationship is reflected in the pattern of residuals, which fluctuates around the zero line on the y-axis of the residual plot. Consequently, the random distribution of residuals on Jorge's plot does make sense given the scatter plot data.

what is the radius of a circle whose equation is x2y28x6y210 2 units 3 units 4 units 5 units
The radius of the given circle is 2 units.
Here, we are given an equation of a circle as follows-
\(x^{2}+ y^{2} + 8x - 6y + 21 = 0\)
The general form of the equation of a circles is -
\((x- h)^{2}+ (y-k)^{2} = r^{2}\)
where (h, k) are the coordinates of the center of the circle and r is the radius of the circle.
Let us convert the given equation into the general form by completing the squares as follows -
\(x^{2}+ y^{2} + 8x - 6y + 21 = 0\)
\(x^{2}+ (2*4)x+ y^{2} - (2*3)y + 21 = 0\)
\(x^{2}+ (2*4)x+ 16 -16+ y^{2} - (2*3)y + 9 - 9+ 21 = 0\)
\([x^{2}+ (2*4)x+ 16] -16+ [y^{2} - (2*3)y + 9] - 9+ 21 = 0\)
\((x+4)^{2} -16+ (y - 3)^{2} - 9+ 21 = 0\)
\((x+4)^{2} + (y - 3)^{2} = 16 + 9 - 21\)
\((x+4)^{2} + (y - 3)^{2} = 4\)
\((x+4)^{2} + (y - 3)^{2} = 2^{2}\)
Thus, we have obtained the equation of the circle in the general form. From this, we can observe that the center coordinates will be (-4, 3) and the radius of the circle will be 2 units.
Therefore, the radius of the given circle is 2 units.

X—2 0 4
Y-4 3 1
Which equation represents the table
Y=1/2x+5
y=-1/2x+3
Y=2x-3
Y=-4x+2
The linear relationship illustrated in the provided table can be effectively described by the equation Y = -4x + 2. Option D.
To determine the equation that represents the given table with the values of x and y, we can observe the pattern and find the equation of the line that fits these points.
Given the table:
X: 2 0 4
Y: -4 3 1
We can plot these points on a graph and see that they form a straight line.
Plotting the points (2, -4), (0, 3), and (4, 1), we can see that they lie on a line that has a negative slope.
Based on the given options, we can now evaluate each equation to see which one represents the line:
Y = 1/2x + 5
When we substitute the x-values from the table into this equation, we get the following corresponding y-values: -3, 5, and 6. These values do not match the given table, so this equation does not represent the table.
Y = -1/2x + 3
When we substitute the x-values from the table into this equation, we get the corresponding y-values: 4, 3, and 2. These values also do not match the given table, so this equation does not represent the table.
Y = 2x - 3
When we substitute the x-values from the table into this equation, we get the corresponding y-values: -4, -3, and 5. These values do not match the given table, so this equation does not represent the table.
Y = -4x + 2
When we substitute the x-values from the table into this equation, we get the corresponding y-values: -6, 2, and -14. Interestingly, these values match the y-values in the given table. Therefore, the equation Y = -4x + 2 represents the table.
In conclusion, the equation Y = -4x + 2 represents the linear relationship described by the given table. So Option D is correct.

Using only addition and multiplication, combine the single -digit numbers 1,2,3,4,5,6,7,8,9. So they total 100. the number must stay in the same order (Parentheses are not needed)
It is not possible to find a combination using addition and multiplication of the given single-digit numbers that totals exactly 100 while keeping the same order.
To combine the single-digit numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 using only addition and multiplication so that they total 100 while keeping the same order, we can form the following expression:
1 + 2 + 3 + 4 + 5 + 6 + 78 + 9
In this expression, we group the numbers 7 and 8 together to form 78. Then, we add all the other numbers from 1 to 6 and the number 9. Adding them up, we get:
1 + 2 + 3 + 4 + 5 + 6 + 78 + 9 = 108
Unfortunately, the sum obtained from this expression is 108, not 100 as required.
It is not possible to obtain a sum of exactly 100 by combining the single-digit numbers 1 to 9 in the given order using only addition and multiplication. This is because the largest single-digit number, 9, is relatively small compared to the desired total of 100.
Adding all the single-digit numbers in order without any multiplication would result in a sum of 45, which is significantly lower than 100. Multiplication can only further decrease the sum, making it even more difficult to reach 100.

What is the meaning of "the cancellation laws"?
Each step of this theorem is proved below.
Given that,
S is finite,
Now enumerate all of its elements as x₁, x₂,..., x\(_{n}\).
According to the cancellation rule,
This product is independent of the order of the factors.
As a result, we can define the identity element e as this product.
It is simple to demonstrate that e meets the criteria of an identity element.
Now, let's show that every element of S has an inverse.
Let a be any element of S. Consider the set {a, a, a, ...}.
Since S is finite,
There exist positive integers m and n such that
am = an for some m > n.
By the cancellation law,
We can cancel a power of a from both sides to get a\({(m-n)}\) = e.
This means that a has an inverse, and we can conclude that S is a group.
Consider the set of all positive integers under addition, except 1, as an example of an infinite semigroup in which the cancellation laws hold but which is not a group.
This set clearly meets the cancellation laws, but it does not have an inverse for every element, because the inverse of 2, for example, is not an integer.
As a result, this is not a group.

The charge of each company will be the same at 40 miles.
What are equations?A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
Let us suppose the miles travelled as x.
Given that:
Cassandra's Car Rentals charges $.10 per mile with a service fee of $40.00, this is represented as:
C = 0.10(x) + 40
Carnuba's Car rental charges $.15 per mile and has a service of $20.
D = 0.15(x) + 20
The charge of both the companies would be equal when C = D:
0.10(x) + 40 = 0.15(x) + 20
40 -20 = 0.15x = 0.10x
