To find the limit of a convergent sequence, we can simply take the limit as n approaches infinity. Let's calculate the limits for each of the given sequences:
A. \(\sf\:\lim_{n \to \infty} \frac{5n}{n+7} \\\)
To find the limit, we divide the leading terms by n:
\(\sf\:\lim_{n \to \infty} \frac{5n/n}{(n+7)/n} = \frac{5}{1} = 5 \\\)
Therefore, the limit of the sequence A is 5.
B. \(\sf\:\lim_{n \to \infty} \frac{4-7n}{8+n} \\\)
Again, divide the leading terms by n:
\(\sf\:\lim_{n \to \infty} \frac{4/n - 7}{8/n + 1} = \frac{0 - 7}{0 + 1} = -7 \\\)
So, the limit of sequence B is -7.
C. \(\sf:\lim_{n \to \infty} \frac{8n - 500\sqrt{n}}{2n + 800\sqrt{n}} \\\)
Divide the leading terms by n:
\(\sf\:\lim_{n \to \infty} \frac{8 - 500\sqrt{n}/n}{2 + 800\sqrt{n}/n} \\\)
As n approaches infinity, the terms involving \(\sf\:\sqrt{n}/n \\\) tend to 0:
\(\sf\:\lim_{n \to \infty} \frac{8 - 500(0)}{2 + 800(0)} = \frac{8}{2} = 4 \\\)
Therefore, the limit of sequence C is 4.
To summarize:
A. The limit of sequence A is 5.
B. The limit of sequence B is -7.
C. The limit of sequence C is 4.

There is a probability of 94/315 that the problem will be solved.
We are given that P has a chance of solving the problem of 2/7, Q has a chance of solving the problem of 4/7, and R has a chance of solving the problem of 4/9. To find the probability that the problem is solved, we need to consider all possible scenarios in which the problem can be solved.
The probability of this scenario is 2/7. If P solves the problem, then it does not matter whether Q or R solve it, the problem is already solved. Therefore, the probability of the problem being solved in this scenario is 2/7.
The probability of this scenario is 4/7. If Q solves the problem, then it does not matter whether P or R solve it, the problem is already solved. Therefore, the probability of the problem being solved in this scenario is 4/7.
The probability of this scenario is 4/9. If R solves the problem, then it does not matter whether P or Q solve it, the problem is already solved. Therefore, the probability of the problem being solved in this scenario is 4/9.
The probability of this scenario is (1-2/7) * (1-4/7) * (1-4/9) = 3/35. This is because the probability of P not solving the problem is 1-2/7, the probability of Q not solving the problem is 1-4/7, and the probability of R not solving the problem is 1-4/9. To find the probability of none of them solving the problem, we multiply these probabilities together.
To find the probability of the problem being solved, we need to add the probabilities of all the scenarios in which the problem is solved. Therefore, the probability of the problem being solved is:
2/7 + 4/7 + 4/9 = 94/315

How would you solve this using the elimination method? Thanks!
Answers
Answer:
x = -1,375
y = -5
Step-by-step explanation:
{-8x + y = 6, / : (-1)
{-8x + 3y = -14;
Multiply the first equation by -1, so that we could eliminate 8x:
+ {8x - y = -6,
{-8x + 3y = -14;
----------------------
4y = - 20 / : 4
y = -5
Now, make x the subject from the first equation (you can do it from the 2nd one instead):
8x = -6 + y / : 8
x = -0,75 + 0,125y
x = -0,75 + 0,125 × (-5) = -0,75 - 0,625 = -1,375

Answers
The statement that is true regarding the function f(x) = (x-4)(x + 1) is that the function is increasing for all real values of x where x < -1 and where x > 4. So, the option is: O The function is increasing for all real values of x where x < -1 and where x > 4.
Explanation: Given function is:f(x) = (x - 4) (x + 1). The graph of the given function is shown below: As it is visible from the graph, the function is decreasing for all real values of x where x lies between -1 and 4 (inclusive).
The turning point of the function is x = -0.5, which is the x-coordinate of the vertex of the parabola. Also, we see that the vertex is the minimum point of the parabola and the y-coordinate of the vertex is -4.25. This means that f(x) ≥ -4.25 for all x. The function is increasing for all real values of x where x < -1 and where x > 4.

Make the lines intersect in such a way that ∠TXV is an obtuse angle less than 135°. Afterwards, use the protractor to determine the precise measure of all four angles. You should redraw the lines if ∠TXV is not the proper size.
Answers
Answer:)Angle FIH and GIE after keeping angle EIH at 140° is 40° while ∠FIG will is the opposite angle of ∠EIH so it will remain the same as 140°.
Step-by-step explanation:We need to intersect both lines and make ∠EIH > 135°
So,Let's keep ∠EIH = 140°
Then,∠FIG = 140° (opposite angle)∠FIH = ∠GIE = x (opposite angle)
Now,The Sum of all angles around I will be 360 degrees.
So,140 + x + 140 + x = 360 ,2x + 280 = 360, 2x = 80 ⇒ x = 40°.
what is the slope of the line
Answers
To find the slope, we can count the change in y over the change in x, or we can use the slope formula. We can count in this graph.
Recall that when calculating the slope, we always start at the y-intercept: the point where the graph intercepts (crosses) the y-axis.
Looking at the graph, the function intercepts the y-axis at y=-2, so we will start at -2 and count from there. To count, we need two defined points such that they intercept a coordinate.
We have the y-intercept at the coordinate: (0, -2). Now, let’s find another point that has a whole number x-value and whole number y-value. We see that the point (-2, 0) is the next closet point. Now, we can count from (0, -2) to (-2, 0), which will determine the slope.
Slope=m
m=2/-2
We rise 2 units from the y-intercept and run 2 units left (hence -2 and not just 2)
Simply:
2/-2=-1
So, m=-1
The slope of the line is -1.

f(x) = x^2(x+7)(x-4)

double roots tend to bounce, kind of like the standard quadratic y = x^2
singular roots tend to cross, kind of like a straight line on a graph, y = mx + b
Therefore, it bounces at x = 0, and crosses at x = -7 and 4
In general, a root raised to an even power bounces, and a root raised to an odd power crosses.

Contruct a 90% confidence interval estimate of the mean net change in LDL cholesterol after garlic. what does the confidence interval suggest about the effectiveness
Answers
The 90% confidence interval estimate of the mean net change in LDL cholesterol after garlic, using the t-distribution, is of:
(-1.14, 8.14).
Since the lower bound of the interval is negative, there is no guarantee of the effectiveness of the method.
What is a t-distribution confidence interval?The t-distribution is used when the standard deviation for the population is not known, only for the sample.
The bounds of the confidence interval are given according to the rule presented below:
\(\overline{x} \pm t\frac{s}{\sqrt{n}}\)
In which the variables of the equation are described as follows:
\(\overline{x}\) is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 43 - 1 = 42 df, is t = 1.6820.
The values of the other parameters are defined as follows:
\(\overline{x} = 3.5, s = 18.1, n = 43\)
Then the lower bound of the confidence interval is calculated as follows:
\(\overline{x} - t\frac{s}{\sqrt{n}} = 3.5 - 1.682\frac{18.1}{\sqrt{43}} = -1.14\)
The upper bound of the confidence interval is calculated as follows:
\(\overline{x} + t\frac{s}{\sqrt{n}} = 3.5 + 1.682\frac{18.1}{\sqrt{43}} = 8.14\)
