Superman needs to save Lois from the clutches of Lex Luthor. After flying for 14 seconds, he is 1372 meters from her. Then at 18 seconds he is 1164 meters from her.
A. What is Superman's average rate? _____ meters per second
B. How far does Superman fly every 15 seconds? _________meters
C. How close to Lois is Superman after 33 seconds? ________meters

Answers

Answer 1

The average rate of Superman can be calculated by dividing the change in distance by the change in time.

Average rate = (final distance - initial distance) / (final time - initial time)

Average rate = (1164 - 1372) / (18 - 14)

Average rate = -208 / 4

Average rate = -52 meters per second

To find how far Superman flies every 15 seconds, we can use the concept of proportionality. Since we know the rate at which Superman is flying, we can set up a proportion to find the distance.

Rate = Distance / Time

-52 meters per second = Distance / 4 seconds

Distance = -52 * 15

Distance = -780 meters (Note: Distance cannot be negative, so we consider the magnitude)

C. To determine how close Superman is to Lois after 33 seconds, we can use the average rate to calculate the distance traveled.

Distance = Average rate * Time

Distance = -52 * 33

Distance = -1716 meters (Note: Distance cannot be negative, so we consider the magnitude)

Let 1 f(z) = z²+1 Determine whether f has an antiderivative on the given domain G. You must prove your claims. (a) G=C\ {i,-i}. (b) G= {z C| Rez >0}.

Answers

f(z) = z^2 + 1 has an antiderivative on the domain G = C \ {i, -i}.

(b) Hence, we cannot determine whether f(z) = z^2 + 1 has an antiderivative on the domain G = {z in C | Re(z) > 0} based on the Cauchy-Goursat theorem alone.

(a) To determine whether f(z) = z^2 + 1 has an antiderivative on the domain G = C \ {i, -i}, we can check if f(z) satisfies the Cauchy-Riemann equations on G.

The Cauchy-Riemann equations state that for a function f(z) = u(x, y) + iv(x, y) to have a derivative at a point, its real and imaginary parts must satisfy the partial derivative conditions:

∂u/∂x = ∂v/∂y and ∂u/∂y = -∂v/∂x.

For f(z) = z^2 + 1, we have u(x, y) = x^2 - y^2 + 1 and v(x, y) = 2xy.

Calculating the partial derivatives, we find:

∂u/∂x = 2x, ∂v/∂y = 2x,

∂u/∂y = -2y, ∂v/∂x = 2y.

Since ∂u/∂x = ∂v/∂y and ∂u/∂y = -∂v/∂x hold for all (x, y) in the domain G, f(z) satisfies the Cauchy-Riemann equations on G. Hence, f(z) has an antiderivative on G = C \ {i, -i}.

(b) Now, let's consider the domain G = {z in C | Re(z) > 0}. To determine if f(z) = z^2 + 1 has an antiderivative on G, we can utilize the Cauchy-Goursat theorem, which states that a function has an antiderivative on a simply connected domain if and only if its line integral around every closed curve in the domain is zero.

For f(z) = z^2 + 1, we can calculate its line integral over a closed curve C in G. However, since G is not simply connected (it has a "hole" at Re(z) = 0), the Cauchy-Goursat theorem does not apply, and we cannot conclude whether f(z) has an antiderivative on G based on this theorem.

To provide a definitive answer, further analysis or techniques such as the residue theorem may be required.

Let X and Y be two independent N(0,2) random variable and Z= 7+X+Y, W= 1+ Y. Find cov(Z, W) and p(Z,W).

Answers

The correlation coefficient (p(Z, W)) between Z and W is sqrt(2) / 2.

To find the covariance of Z and W and the correlation coefficient (p(Z, W)), we can use the properties of covariance and correlation for independent random variables.

Given that X and Y are independent N(0, 2) random variables, we know that their means are zero and variances are 2 each.

Covariance:

Cov(Z, W) = Cov(7 + X + Y, 1 + Y)

Since X and Y are independent, the covariance between them is zero:

Cov(X, Y) = 0

Using the properties of covariance, we have:

Cov(Z, W) = Cov(7 + X + Y, 1 + Y)

= Cov(X, Y) + Cov(Y, Y)

= Cov(X, Y) + Var(Y)

Since Cov(X, Y) = 0 and Var(Y) = 2, we can substitute these values:

Cov(Z, W) = 0 + 2

= 2

Therefore, the covariance of Z and W is 2.

Correlation Coefficient:

p(Z, W) = Cov(Z, W) / (sqrt(Var(Z)) * sqrt(Var(W)))

To calculate p(Z, W), we need to find Var(Z) and Var(W):

Var(Z) = Var(7 + X + Y)

= Var(X) + Var(Y) (since X and Y are independent)

= 2 + 2 (since Var(X) = Var(Y) = 2)

= 4

Var(W) = Var(1 + Y)

= Var(Y) (since 1 is a constant and does not affect variance)

= 2

Now we can calculate p(Z, W):

p(Z, W) = Cov(Z, W) / (sqrt(Var(Z)) * sqrt(Var(W)))

= 2 / (sqrt(4) * sqrt(2))

= 2 / (2 * sqrt(2))

= 1 / sqrt(2)

= sqrt(2) / 2

Therefore, the correlation coefficient (p(Z, W)) between Z and W is sqrt(2) / 2.

Consider a drug testing company that provides a test for marijuana usage. Among 308 tested subjects, results from 29 subjects were wrong. (either a false positive or a false negative). Use a 0.05 significance level to test the claim that less than 10 percent of the test results are wrong.

Answers

The required answer is  based on the given data, we do not have sufficient evidence to support the claim that less than 10 percent of the test results are wrong at a 0.05 significance level.

To test the claim that less than 10 percent of the test results are wrong, use a hypothesis test with a significance level of 0.05. Let's define the null and alternative hypotheses:

Null Hypothesis (H0): The proportion of wrong test results is 10 percent or more.

Alternative Hypothesis (Ha): The proportion of wrong test results is less than 10 percent.

Use the binomial distribution to analyze the data. Let p be the true proportion of wrong test results. Since we want to test that the proportion is less than 10 percent, set p = 0.10 for the null hypothesis.

Given that 29 out of 308 tested subjects had wrong test results,  calculate the sample proportion, denoted by p^, as follows:

p^ = 29 / 308 = 0.094

To conduct the hypothesis test, we can use the z-test for proportions. The test statistic is calculated as:

z = (p^ - p) / [tex]\sqrt{}[/tex]((p x (1 - p)) / n)

In this case, since we are testing whether the proportion is less than 10 percent, calculate a one-tailed z-test.

Substituting the values into the formula:

z = (0.094 - 0.10) / [tex]\sqrt{}[/tex]((0.10 x (1 - 0.10)) / 308)

Simplifying the expression:

z = -0.006 /[tex]\sqrt{}[/tex] (0.09 / 308)

z ≈ -0.006 / 0.017

Calculating the z-value:

z ≈ -0.353

To determine the critical value for a one-tailed test at a significance level of 0.05, we can consult the z-table or use statistical software. For a significance level of 0.05, the critical z-value is approximately -1.645 (since we are testing for less than 10 percent, in the left tail).

Since the calculated z-value (-0.353) is greater than the critical z-value (-1.645), we fail to reject the null hypothesis. There is not enough evidence to conclude that the proportion of wrong test results is less than 10 percent.

Therefore, based on the given data, we do not have sufficient evidence to support the claim that less than 10 percent of the test results are wrong at a 0.05 significance level.

What is the equation of the asymptote for the functionf(x) = 0.7(4x-3) - 2?

Answers

The equation of the asymptote for the given function f(x) = 0.7(4x-3) - 2 is y = 2.8x - 4.1.

The equation of an asymptote for a function can be determined by analyzing the behavior of the function as x approaches positive or negative infinity.

For the given function f(x) = 0.7(4x-3) - 2, let's simplify it:

f(x) = 2.8x - 2.1 - 2

f(x) = 2.8x - 4.1

As x approaches positive or negative infinity, the term 2.8x dominates the function. Therefore, the equation of the asymptote can be determined by considering the behavior of the linear term.

The coefficient of x is 2.8, so the slope of the asymptote is 2.8. The y-intercept of the asymptote can be found by setting x to 0 in the equation, resulting in -4.1. Therefore, the equation of the asymptote is y = 2.8x - 4.1.

In conclusion, the equation of the asymptote for the given function f(x) = 0.7(4x-3) - 2 is y = 2.8x - 4.1.

Use the Central Limit Theorem to find the mean and standard error of the mean of the indicated sampling distribution. The monthly rents for studio apartments in a certain city have a mean of $900 and a standard deviation of $180. If random samples of size 30 are drawn from the population, identify the mean, wx, and standard deviation, 7, of the sampling distribution of sample means with sample size n

Answers

Mean of the sampling distribution (wx): $900

Standard error of the mean (σx): Approximately $32.92

To find the mean and standard error of the mean of the sampling distribution, we can use the Central Limit Theorem.

The Central Limit Theorem states that for a large enough sample size, the sampling distribution of the sample means will be approximately normally distributed, regardless of the shape of the population distribution.

In this case, the population mean is μ = $900 and the population standard deviation is σ = $180. We are drawing random samples of size n = 30 from this population.

The mean of the sampling distribution (wx) will be equal to the population mean (μ), which is $900.

The standard deviation of the sampling distribution (σx), also known as the standard error of the mean, can be calculated using the formula:

σx = σ / √n

where σ is the population standard deviation and n is the sample size.

Substituting the given values, we have:

σx = $180 / √30

Calculating this value, we find:

σx ≈ $32.92

Therefore, the mean of the sampling distribution (wx) is $900, and the standard error of the mean (σx) is approximately $32.92.

Please note that the Central Limit Theorem assumes a sufficiently large sample size (typically n ≥ 30) for the approximation to hold.

a right triangle, with a height of 4m and a width of 1m. he wants to build a rectangular enclosure to protect himself. what is the largest the area of gottfried’s enclosure can be?

Answers

Given that, height of the right-angled triangle = 4m. Width of the right-angled triangle = 1m. Let's assume that the rectangular enclosure will be built at the base of the right-angled triangle. The area of the rectangular enclosure can be obtained using the formula, Area of rectangle = length × breadth. Length of the rectangle = height of the right-angled triangle = 4mLet the breadth of the rectangle be x, then the length is the width of the right-angled triangle + x = 1 + x Hence, the area of the rectangular enclosure is given by: Area = Length × Breadth= (1+x)×4= 4x + 4m²Now, the maximum area can be obtained by differentiating the above expression with respect to x and equating it to zero: dA/dx = 4 = 0x = -1. This is not a valid solution since we cannot have a negative breadth, hence we conclude that the area is maximum when the breadth of the rectangular enclosure is equal to the width of the right-angled triangle, i.e., when x = 1m. Thus, Area of the rectangular enclosure = Length × Breadth= (1+1)×4= 8 m². Hence, the largest the area of Gottfried’s enclosure can be is 8 m².

The diagonal of TV set is 39 inches long. length is 21 inches more than the height. Find the dimensions of the TV set a. The height of the TV set is ___ inches. b. The length of the TV set is ___ inches.

Answers

Let's assume the height of the TV set is h inches.

a. The height of the TV set is h inches.

Given that the length is 21 inches more than the height, the length can be represented as h + 21 inches.

b. The length of the TV set is h + 21 inches.

According to the given information, the diagonal of the TV set is 39 inches. We can use the Pythagorean theorem to relate the height, length, and diagonal:

(diagonal)^2 = (height)^2 + (length)^2

Substituting the values, we have:

39^2 = h^2 + (h + 21)^2

Expanding and simplifying:

1521 = h^2 + h^2 + 42h + 441

2h^2 + 42h + 441 - 1521 = 0

2h^2 + 42h - 1080 = 0

Dividing the equation by 2 to simplify:

h^2 + 21h - 540 = 0

We can solve this quadratic equation by factoring or using the quadratic formula. Factoring gives us:

(h - 15)(h + 36) = 0

So h = 15 or h = -36.

Since the height of the TV set cannot be negative, we discard h = -36.

Therefore, the height of the TV set is 15 inches.

Substituting this value back into the length equation, we have:

Length = h + 21 = 15 + 21 = 36 inches.

So, the dimensions of the TV set are:

a. The height of the TV set is 15 inches.

To solve the Cauchy-Euler equation x³y'" - 2x²y" - 2xy' + 8y = 0, we'll make the substitution y = [tex]x^r[/tex], where r is a constant.

Let's differentiate y with respect to x:

y' = [tex]rx^{r-1}[/tex]

y" = [tex]r(r-1)x^{r-2}[/tex]

y'" = [tex]r(r-1)(r-2)x^{r-3}[/tex]

Now, substitute these derivatives into the original equation:

[tex]x^3(r(r-1)(r-2)x^{r-3} - 2x^2(r(r-1)x^{r-2}) - 2x(rx^{r-1}) + 8x^r = 0[/tex]

Simplifying, we get:

[tex]r(r-1)(r-2)x^r - 2r(r-1)x^r - 2rx^r + 8x^r = 0[/tex]

Combining like terms, we have:

r(r-1)(r-2) - 2r(r-1) - 2r + 8 = 0

Simplifying further, we get:

r³ - 3r² + 2r - 2r² + 2r + 8 - 2r + 8 = 0

r³ - 3r² + 8 = 0

To solve this cubic equation, we can try to find a rational root using the Rational Root Theorem or use numerical methods to approximate the roots.

By inspection, we find that r = 2 is a root of the equation. This means (r - 2) is a factor of the equation.

Using long division or synthetic division, we can divide r^3 - 3r^2 + 8 by (r - 2):

  2  |   1    -3    0    8

      |       2   -2   -4

_______________________

       1    -1   -2    4

The quotient is r² - r - 2.

Factoring r² - r - 2, we get:

r² - r - 2 = (r - 2)(r + 1)

So the roots of the equation r³ - 3r² + 8 = 0 are: r = 2, r = -1 (repeated root).

Therefore, the general solution to the Cauchy-Euler equation x³y'" - 2x²y" - 2xy' + 8y = 0 is given by:

Suppose a brewery has a filling machine that fills 12 ounce bottles of beer. It is known that the amount of beer poured by this filling machine follows a normal distribution with a mean of 12.29 ounces and a standard deviation of 0.04 ounce. Find the probability that the bottle contains between 12. 19 and 12.25 ounces.

Answers

The probability that the bottle contains between 12.19 and 12.25 ounces is 0.1525.

Given, mean (μ) = 12.29 ounces and standard deviation (σ) = 0.04 ounce.

We need to find the probability that the bottle contains between 12. 19 and 12.25 ounces.

So, let X be the amount of beer filled by the machine. Then, X ~ N(12.29, 0.04²)

Let Z be the standard normal random variable.

Then, Z = `(X - μ)/σ`

Substituting the values, we get,Z = `(X - 12.29)/0.04`

For X = 12.19, `Z = (12.19 - 12.29)/0.04 = -2.5`

For X = 12.25, `Z = (12.25 - 12.29)/0.04 = -1

`Now we need to find the probability of Z being between -2.5 and -1.P(Z lies between -2.5 and -1) = P(-2.5 < Z < -1)

We know that P(Z < -1) = 0.1587 and P(Z < -2.5) = 0.0062

From standard normal distribution table, we get

P(-2.5 < Z < -1)

= P(Z < -1) - P(Z < -2.5)P(-2.5 < Z < -1)

= 0.1587 - 0.0062 = 0.1525

Therefore, the probability that the bottle contains between 12.19 and 12.25 ounces is 0.1525.

Given that, △ABC ∼ △EFG. Also, m∠A = 39° and m∠F = 56°. We need to find m∠C.

Let us first write down the formula for the similarity of triangles.  The two triangles are similar if their corresponding angles are congruent.

In other words, we can write: `∠A ≅ ∠E`, `∠B ≅ ∠F`, and `∠C ≅ ∠G`.

Now, in △ABC, we have: ∠A + ∠B + ∠C = 180° (Interior angle property of a triangle)

Also, in △EFG, we have: ∠E + ∠F + ∠G = 180°(Interior angle property of a triangle)

We know that ∠A ≅ ∠E and ∠B ≅ ∠F.

Substituting these values, we get:

39° + ∠B + ∠C = 180° (From △ABC)56° + ∠B + ∠G = 180° (From △EFG)

Simplifying, we get ∠B + ∠C = 141°...(Eq 1)

∠B + ∠G = 124°....  (Eq 2)

Level of confidence = 97%

The level of confidence that corresponds to a z-score of 1.88 is 97% (using a standard normal table or calculator).

That is, z = 1.88 (by referring to a standard normal table or calculator)

To calculate the margin of error, we need to substitute the values in the formula

E = zσ/ √n

E = (1.88) (0.87) / √51

E = 0.3081 oz (approx)

Hence, the margin of error is approximately 0.31 oz (rounding the answer to two decimal places).

sketch the graph of a function that has a local maximum at 6 and is differentiable at 6.

Answers

To sketch the graph of a function that has a local maximum at 6 and is differentiable at 6, we can consider a function that approaches a maximum value at 6 and has a smooth, continuous curve around that point.

In the graph, we can depict a curve that gradually increases as we move towards x = 6 from the left side. At x = 6, the graph reaches a peak, representing the local maximum. From there, the curve starts to decrease as we move towards larger x-values.

The important aspect to note is that the function should be differentiable at x = 6, meaning the slope of the curve should exist at that point. This implies that there should be no sharp corners or vertical tangents at x = 6, indicating a smooth and continuous transition in the graph.

By incorporating these characteristics into the graph, we can represent a function with a local maximum at 6 and differentiability at that point.
