The midpoint of segment ST is M(5,2). One endpoint is S(-1, -7). Find the coordinates of the other endpoint.

Answer:

300

Step-by-step explanation:

225 is what you start with. 15 liter per min means in 5 min it will be 75 because 5x15=75, then 75+225=300

The system is not linear because it doesn't satisfy the superposition and homogeneity conditions. Linear systems are those that satisfy the following two conditions: Superposition and Homogeneity.

Homogeneity:

If the input of the system is multiplied by a constant, then the output of the system is multiplied by the same constant.

Suppose a system S, which takes an input x(t) and produces an output y(t).

If a is any constant, then

S[a * x(t)] = a * S[x(t)]

Superposition: The output of the sum of the inputs is equal to the sum of the outputs of each input separately.

If two inputs are given, say x1(t) and x2(t), and their respective outputs are y1(t) and y2(t), then the output of the system to the sum of the inputs is the sum of the outputs of each input separately.

That is, for any two inputs x1(t) and x2(t) that generate the corresponding outputs y1(t) and y2(t), respectively, we have that:

S[x1(t) + x2(t)] = S[x1(t)] + S[x2(t)]

Therefore, to know if the system is linear or not, it's important to verify if it satisfies these two conditions.

Let's verify if the given system satisfies them:

Homogeneity: Suppose that x(t) is the input to the system, then we need to verify whether the system satisfies the homogeneity condition.

Let a be any constant, then

S[ax(t)] = dºg(t) + 3ad(x(t)) + 4ay(t)

= a(2d(o)(t) + 3x(t))dt2 dt dtS[ax(t)]

= aS[x(t)]

Therefore, the system is homogeneous of degree 1.

Superposition:

Let x1(t) and x2(t) be two inputs, and let y1(t) and y2(t) be the corresponding outputs.

We need to verify whether the system satisfies the superposition condition. Then

S[x1(t) + x2(t)] = dºg(t) + 3d(x1(t) + x2(t)) + 4y1(t) + y2(t)

= dºg(t) + 3d(x1(t)) + 4y1(t) + dºg(t) + 3d(x2(t)) + 4y2(t)

= S[x1(t)] + S[x2(t)]

As the system does not satisfy the superposition condition, then it's not a linear system.

b. x = 3.5, y = 4.5, OFV = 59.5;

c. s1 = 0, s2 = 2, s3 = 0.

a. The extreme points of the feasible region are the vertices of the polygon formed by the intersection of the constraint lines. In this case, the extreme points are (0,0), (5,0), (3.75, 3.75), (3.5,4.5), and (0,8).

b. To find the optimal solution and the objective function value, we evaluate the objective function at each extreme point and choose the point that maximizes the objective function. In this case, the point (3.5, 4.5) maximizes the objective function with a value of 59.5. Therefore, the optimal solution is x = 3.5 and y = 4.5, and the objective function value is 59.5.

c. The slack variables represent the surplus or slack in each constraint. We calculate the slack variables by subtracting the actual value of the left-hand side of each constraint from the right-hand side. In this case, the values of the slack variables are s1 = 0 (indicating no slack in the first constraint), s2 = 2 (indicating a surplus of 2 in the second constraint), and s3 = 0 (indicating no slack in the third constraint).

Therefore, the correct option is:

a. (0,0), (5,0), (3.75, 3.75), (3.5,4.5), (0,8);

b. x = 3.5, y = 4.5, OFV = 59.5;

Since the exponential function is always positive, there is no solution for e^(-2t) = -1/6. This means that the derivative is never equal to zero, and there is no point of maximum steepness for this curve.

To find the point at which the curve is steepest, we need to find the maximum value of the derivative of the function. Let's start by finding the derivative of the given function:

y = 50 / (1 + 6e^(-2t))

To find the derivative, we can use the quotient rule:

y' = [50(0) - (1 + 6e^(-2t))(-12e^(-2t))]/(1 + 6e^(-2t))^2

Simplifying this expression, we get:

y' = (72e^(-2t))/(1 + 6e^(-2t))^2

To find the maximum point, we need to find the value of t for which the derivative is equal to 0. Setting y' = 0 and solving for t, we have:

(72e^(-2t))/(1 + 6e^(-2t))^2 = 0

Since the numerator cannot be zero, we focus on the denominator:

(1 + 6e^(-2t))^2 = 0

Taking the square root of both sides, we get:

1 + 6e^(-2t) = 0

Solving for e^(-2t), we have:

e^(-2t) = -1/6

To solve the equation and find the radius, we need to rewrite it in the form of a circle equation, which is (x - h)² + (y - k)² = r², where (h, k) represents the center of the circle and r represents the radius.

Given equation: x² + y² + 2x - 10y + 8 = 8y - 46

To rewrite the equation in the form (x - h)² + (y - k)² = r², we complete the square for both the x and y terms:

[tex]\sf\:(x^2 + 2x) + (y^2 + 10y) = 8y - 46 - 8 \\[/tex]

Completing the square for x terms:

[tex]\sf\:x^2 + 2x = (x + 1)^2 - 1 \\[/tex]

Completing the square for y terms:

[tex]\sf\:y^2 + 10y = (y + 5)^2 - 25 \\[/tex]

Substituting the completed square forms into the equation:

[tex]\sf\:(x + 1)^2 - 1 + (y + 5)^2 - 25 + 8 = 8y - 46 - 8 \\[/tex]

Simplifying the equation:

[tex]\sf\:(x + 1)^2 + (y + 5)^2 = 8y - 46 - 8 + 1 + 25 - 8 \\[/tex]

[tex]\sf\:(x + 1)^2 + (y + 5)^2 = 8y - 36 \\[/tex]

Now we can see that the equation is in the form of (x - h)² + (y - k)² = r², where h = -1, k = -5, and r² = 8y - 36. Therefore, the radius is [tex]\sf\:\sqrt{8y - 36} \\[/tex].

Step-by-step explanation:

Based on the evidence from the given sample, we have sufficient evidence to refute the claim that the mean is 40 with a standard deviation of 15.

To determine whether the evidence refutes the claim that the mean is 40 with a standard deviation of 15, we can perform a hypothesis test using the given sample mean and the claimed mean.

Let's set up the null and alternative hypotheses:

Null hypothesis (H0): The mean is equal to 40 (µ = 40).

Alternative hypothesis (HA): The mean is not equal to 40 (µ ≠ 40).

We can use a t-test to compare the sample mean to the claimed mean. Given that we have a sample size of 100, we can assume the sample mean follows an approximately normal distribution due to the Central Limit Theorem.

The test statistic for this scenario is the t-score, which measures the difference between the sample mean and the claimed mean in terms of standard errors.

The formula for the t-score is:

t = (sample mean - claimed mean) / (sample standard deviation / sqrt(sample size))

Using the given information, we can calculate the t-score:

t = (35.8 - 40) / (15 / sqrt(100))

t = -4.2 / (15 / 10)

t = -4.2 / 1.5

t = -2.8

Next, we need to compare the t-score with the critical value at a given significance level (e.g., α = 0.05) and the degrees of freedom (df = n - 1 = 100 - 1 = 99).

Using a t-table or statistical software, we can find the critical values for a two-tailed test with a significance level of 0.05 and 99 degrees of freedom. The critical t-values are approximately -1.984 and 1.984.

Since the calculated t-score (-2.8) is outside the range of the critical values (-1.984 to 1.984), we reject the null hypothesis.

Therefore, based on the evidence from the given sample, we have sufficient evidence to refute the claim that the mean is 40 with a standard deviation of 15.

In a binomial experiment with n trials and probability of success p, if n is large and/or p is close to 0.5, the binomial random variable X is approximately normal with μX = np and σX = sqrt(np(1-p)).

In a binomial experiment with n trials and probability of success p, if n is large and/or p is close to 0.5, the binomial random variable X is approximately normal with μX = np and σX = sqrt(np(1-p)). A binomial experiment involves a fixed number of independent trials (n) each having the same probability of success (p).The binomial distribution is a discrete probability distribution that describes the probability of success in a binomial experiment. When the sample size is large, the binomial distribution may be approximated by the normal distribution.This is because the normal distribution is continuous, whereas the binomial distribution is discrete. If the sample size is large enough, the binomial distribution can be well approximated by the normal distribution. For this approximation to work well, n should be large and p should be close to 0.5.When the binomial distribution is approximated by the normal distribution, the mean of the binomial distribution, which is np, is also the mean of the normal distribution. The standard deviation of the normal distribution is the square root of np(1-p).

In summary, when n is large and/or p is close to 0.5, the binomial random variable X is approximately normal with μX = np and σX = sqrt(np(1-p)).
