Answer:

the answer is 71,209 visitor

Step-by-step explanation:

12,629 + 24,290 + 24,290 = 71,209

The distance of the object from the helicopter based on the information about the height given will be 460 feet.

Your information is incomplete and the diagram wasn't found. This will be solved based on assumed figures.

From the information given, we are told that the helicopter hovering above a command post shines a spotlight on an object on the ground 250 feet away from the command post and we want to calculate the distance of the object from the helicopter.

Let's assume that the helicopter climbs 20 feet per seconds

Also, based on the information given, let us assume that the object is 10 seconds away.

Therefore, the distance will be calculated thus:

d = 250 + 21t

d = 250 + 21(10)

d = 250 + (21 × 10)

d = 250 + 210

d = 460 feet

Hence, based on the information, the distance of the object from the helicopter will be 460 feet.

Answer:

266.67 feet^2.

Step-by-step explanation:

The scale is 1:40.

That means that if the scale has a width of 4 inches, the room will have a width of 4 * 40 = 160 inches. 160 / 12 = 80 / 6 = 40 / 3 feet.

The length in the model is 6 inches, so the room has a length of 6 * 40 = 240 inches. 240 / 12 = 120 / 6 = 60 / 3 = 20 feet.

The area will then be (40 / 3) * 20 = 800 / 3 = 266.67 feet^2.

look at the picture

Given:

The perimeter of a rectangle is 84cm.

The length is 12 cm longer than the width.

Required:

We need to find the length and width of the rectangle.

Explanation:

Let l be the length of the rectangle and w be the width of the rectangle.

The length is 12 cm longer than the width.

Add 12 to the width to get the length.

Consider the perimeter of the rectangle formula.

Substitute l=12+w and P =84 in the formula.

Subtract 24 from both sides of the equation.

Divide both sides of the equation by 4.

Substitute w =15 in the equation l=12+w.

Final answer:

The length of the rectangle is 27 cm.

The width of the rectangle is 15 cm.

Answer: y = (5x/4) + 2

Step-by-step explanation:

Answer:

y = 5/4x + 2

Step-by-step explanation:

First, we convert 4x + 5y = 15 to slope intercept form (y=mx+b):

5y = -4x + 15

Divide both sides by five

y = -4/5 (x) + 3

The slope is -4/5

A perpendicular slope is the negative reciprocal of the other line. To find the negative reciprocal, you switch the numerator and denominator and switch the sign.

Slope = 5/4

Plug the slope and (-4, -3) into the slope-intercept form:

-3 = ( 5/4 · -4 ) + b

Isolate b (the y-intercept):

-3 = -5 + b

b = 2

y = 5/4x + 2

Step-by-step explanation:

Trace sends multiple ICMP packets with progressively higher Time-to-Live until the packet reaches the destination.

Traceroute is a network diagnostic tool that helps identify the path taken by packets from a source to a destination. It achieves this by sending ICMP packets, also known as Internet Control Message Protocol packets, with an increasing value for a specific parameter called the Time-to-Live (TTL). The TTL value determines how many hops, or intermediate network devices, a packet can traverse before being discarded.

Now, the first router receives the ICMP packet and decrements the TTL value by 1. If the TTL becomes zero, the router discards the packet and sends an ICMP "Time Exceeded" message back to the source host. This message indicates that the packet's TTL has expired, and the source host can determine the IP address of the router.

In summary, when we use traceroute, we send multiple ICMP packets with progressively higher TTL values until the packet reaches the destination host. Each router encountered along the way decrements the TTL value, and if it reaches zero, the router generates a "Time Exceeded" message. This process allows us to trace the network path and identify the intermediate devices that the packets traverse.

The number of independent people (X) who view the ad until someone clicks on it (including the person who clicked on the ad), then X follows a geometric distribution with a probability of success p = 0.22.

Question 1: What is the probability that the first person who views the ad clicks on it?

Answer: Since X follows a geometric distribution, the probability that the first person who views the ad clicks on it is equal to the probability of success, which is p = 0.22.

Question 2: What is the probability that at least three people need to view the ad until someone clicks on it?

Answer: To find the probability that at least three people need to view the ad until someone clicks on it, we need to calculate the probability that it takes three or more people. This is equal to 1 minus the cumulative probability up to two people. The cumulative probability of X less than or equal to 2 is given by:

P(X ≤ 2) = P(X = 1) + P(X = 2)

Since X follows a geometric distribution, the probability mass function is given by:

P(X = k) = \(1-p^{(k-1)}\) × p

Using this formula, we can calculate:

P(X ≤ 2) = P(X = 1) + P(X = 2) = \(1-0.22^{(1-1)}\) × 0.22 + \(1-0.22^{(2-1)}\)× 0.22

Question 3: What is the expected value (mean) of X?

Answer: The expected value (mean) of a geometric distribution with probability of success p is given by E(X) = 1/p. Therefore, the expected value of X in this case is:

E(X) = 1/0.22

Question 4: What is the standard deviation of X?

Answer: The standard deviation of a geometric distribution with probability of success p is given by σ(X) = √(q/p²), where q = 1 - p. Therefore, the standard deviation of X in this case is:

σ(X) = √((1 - 0.22)/(0.22²))

Question 5: What is the probability that it takes exactly five people to click on the ad?

Answer: Since X follows a geometric distribution, the probability of X = 5 is given by:

P(X = 5) = \(1-p^{(5-1)}\) × p

Using this formula, we can calculate the probability that it takes exactly five people to click on the ad.

The eccentricity of the conic section defined by the equation r = 3/4 - 3sin(θ) is e = 3. This means that the correct answer is (E) e = 3.

The equation, r = 3/4 - 3sin(θ), represents a polar equation of a conic section. To determine the eccentricity (e), we can examine the coefficient of sin(θ) in the equation.

The general form of a polar equation for a conic section is r = (1 - e²)/(1 + e*cos(θ)), where e represents the eccentricity. By comparing this general form with the given equation, we can see that the coefficient of sin(θ) is -3.

Since the coefficient of sin(θ) in the equation is -3, and the general form of a conic section has a coefficient of cos(θ), we can conclude that the eccentricity (e) is equal to 3.

Therefore, the correct answer is (E) e = 3.

Step-by-step explanation:

The magnetic field $H$ in the interface between region 1 and region 2 is $2.7a$ mWb/m$^2$, and the angle it makes with the positive $x$-axis is $\arctan(\frac{1.8}{2.7}) = \boxed{33^\circ}$.

The magnetic field in region 1 is given by $B = 2.5a_x + 6a_z$ mWb/m$^2$, and the magnetic field in region 2 is given by $B = 4.2a_x + 1.8a_z$ mWb/m$^2$. The interface between the two regions is defined by $z = 0$.

We can use the boundary condition for magnetic fields to find the magnetic field at the interface:

B_1(z = 0) = B_2(z = 0)

Substituting the expressions for $B_1$ and $B_2$, we get:

2.5a_x + 6a_z = 4.2a_x + 1.8a_z

Solving for $H$, we get:

H = 2.7a

The angle that $H$ makes with the positive $x$-axis can be found using the following formula:

tan θ = \frac{B_z}{B_x} = \frac{1.8}{2.7} = \frac{2}{3}

The angle θ is then $\arctan(\frac{2}{3}) = \boxed{33^\circ}$.

The first step is to use the boundary condition for magnetic fields to find the magnetic field at the interface. We can then use the definition of the tangent function to find the angle that $H$ makes with the positive $x$-axis.

The boundary condition for magnetic fields states that the magnetic field is continuous across an interface. This means that the components of the magnetic field in the two regions must be equal at the interface.

In this case, the two regions are defined by $z = 0$, so the components of the magnetic field must be equal at $z = 0$. We can use this to find the value of $H$ at the interface.

Once we have the value of $H$, we can use the definition of the tangent function to find the angle that it makes with the positive $x$-axis. The tangent function is defined as the ratio of the $z$-component of the magnetic field to the $x$-component of the magnetic field.

In this case, the $z$-component of the magnetic field is 1.8a, and the $x$-component of the magnetic field is 2.7a. So, the angle that $H$ makes with the positive $x$-axis is $\arctan(\frac{1.8}{2.7}) = \boxed{33^\circ}$.

This exact area under the parametric curve x = √t, y = 2t - \(t^2\), where 0 ≤ t ≤ 2  is 2√2 - (2/5) \(2^(5/2)\) .

The formula for finding the area under a parametric curve is A = ∫[a,b] y(t) * x'(t) dt, where x(t) and y(t) are the parametric equations defining the curve.

In this case, the parametric equations are x = √t and y = 2t - \(t^2\), and the range of t is 0 ≤ t ≤ 2. To find the exact area, we need to evaluate the integral ∫[0,2] (2t - \(t^2\)) * (√t)' dt.

First, we find the derivative of √t with respect to t. Since (√t)' = (\(t^(1/2)\))' = \((1/2)t^(-1/2)\) = 1/(2√t), we have x'(t) = 1/(2√t). Next, we substitute the expressions for y(t) and x'(t) into the integral:

A = ∫[0,2] (2t - \(t^2\)) * (1/(2√t)) dt.

Simplifying, we get:

A = (1/2) ∫[0,2] (2t - \(t^2\)) / √t dt.

Expanding and rearranging the terms:

A = (1/2) ∫[0,2] (2t/√t - \(t^(3/2)\)) dt.

Now we can integrate each term separately:

A = (1/2) (∫[0,2] 2t/√t dt - ∫[0,2] \(t^(3/2)\) dt).

For the first integral, we use the substitution u = √t, du = (1/2) \(t^(-1/2)\) dt. The limits of integration become u = 0 and u = √2. The integral simplifies to:

∫[0,2] 2t/√t dt = 4 ∫[0,√2] du = 4u ∣[0,√2] = 4√2.

For the second integral, we use the power rule to integrate t^(3/2):

∫[0,2] \(t^(3/2)\) dt = (2/5) \(t^(5/2)\) ∣[0,2] = (2/5) (2^(5/2) - 0) = (2/5) \(2^(5/2)\).

Substituting these results back into the original expression for A:

A = (1/2) (4√2 - (2/5) \(2^(5/2)\)).

Simplifying further:

A = 2√2 - (2/5) \(2^(5/2)\).

This is the exact area under the parametric curve x = √t, y = 2t - \(t^2\), where 0 ≤ t ≤ 2.

The chi-square statistic of 3.86 is not statistically significant if the critical value obtained from the distribution of chi-square is 6.63 with an alpha level of .01.

To determine if the obtained chi-square statistic of 3.86 is statistically significant or not, we need to compare it to the critical value obtained from the distribution of chi-square, which is 6.63, at a significance level of 0.01.

In this case, the obtained chi-square value is less than the critical value, indicating that we fail to reject the null hypothesis. This means that the observed frequencies in the sample are not significantly different from the expected frequencies based on the null hypothesis. The alpha level of 0.01 indicates that we are willing to accept a 1% chance of making a Type I error, which is rejecting the null hypothesis when it is actually true. Since the obtained chi-square value is not greater than the critical value, we do not have sufficient evidence to reject the null hypothesis.

In summary, the results are not statistically significant at the 0.01 significance level, based on the obtained chi-square statistic of 3.86 and the critical value of 6.63. This means that there is no significant difference between the observed and expected frequencies, based on the null hypothesis.

Let's compute the left-hand limit:

\(\lim_{x \to \ 0^-} a_n (1 + arctan x)^(^1^/^x^2^)\)

As x approaches 0 from the left side, arctan x approaches -π/2. Therefore, we can rewrite the expression as:

Now, let's evaluate the limit:

\(\left(1\:+\:\left(-\pi /2\right)\right)^\infty\)

To determine the value of this expression, we can rewrite it using the exponential function:

\(= e^(^\infty^l^n^(^1 ^+ ^(^-^\pi^/^2^)^))\)

Now, let's analyze the term ln(1 + (-π/2)). Since -π/2 is negative, 1 + (-π/2) will be less than 1.

Therefore, ln(1 + (-π/2)) is negative.

When we multiply a negative number by ∞, the result is -∞.

So, we have:
