The maximum electric field strength in the electromagnetic wave is found as 144 kV/m.

To determine the maximum electric field strength (in kV/m) of an electromagnetic wave, you can use the following relation between electric field strength (E) and magnetic field strength (B):

E = c * B

where E is the electric field strength, B is the magnetic field strength, and c is the speed of light in a vacuum, which is approximately 3.00 x 10^8 m/s.

Given a maximum magnetic field strength of 4.80 x 10^-4 T, you can find the maximum electric field strength by plugging in the values:

E = (3.00 x 10^8 m/s) * (4.80 x 10^-4 T)

E ≈ 1.44 x 10^5 V/m

To convert this value to kV/m, divide by 1000:

E ≈ 144 kV/m

So, the maximum electric field strength in the electromagnetic wave is approximately 144 kV/m.

Step-by-step explanation:

The amygdala is the brain's emotional center. It is responsible for instinctual thinking and impulse control. It develops during early teenage years and this means the amygdala is not developed to the optimal level during teenage years. This makes teenagers very prone to impulsive behavior.

Also, the prefrontal cortex which is responsible for decision-making skills and the ability to measure risks is not fully developed in the teenage child stage. This is why teenagers make poor decisions and aren't great at measuring risks thereby making riskier choices like using the phone while driving.

These two brain components are fully developed in adults hence, it is less likely for adults to make poor decisions like texting while driving, which is a riskier thing to do than not using a seatbelt.

Again, teenagers have this invincibility feeling where they feel like they are more active and can react faster to road dangers. This deceives them into making such riskier decisions.

The current world also has turned into something else where people (teenagers especially) strive to get the most current news information as they are happening. The need to stay connected to social media is another reason why teenagers can't stay off their phones.

Finally, the fact that public intervention programs and ad campaigns promoting seat-belt use way more than not using cell-phones use while driving also mean more people are more conscious about using seatbelts while driving than not using their cellphones. In recent times, the campaigns, laws and bans on use of phones while driving are just gaining prominence.

In conclusion, the combination of all these factors/reasons is why the percentage of teenage high school students who use phones while driving is way more than the percentage that don't use a seatbelt although texting while driving is arguably much riskier than not wearing a seat belt.

Answer:

Angle ACE=80º

Step-by-step explanation:

Since the angles ACD and ACE are supplementary (meaning they form a straight line or 180º when added up) we know that the sum of those angles is 180º.

If ACD + ACE = 180 and ACD =100

then, 100 + ACE =180 and by subtracting we find that ∠ACE=80º.

Answer:

2.75 miles jogged on the fourth day

Step-by-step explanation:

Justin jogged 2 miles on the first day.

On the second day he jogged 75% of 2 miles. To find 75% of 2 miles we need to divide by 100 and multiply by 75.

2 / 100 = 0.02 x 75 = 1.5 miles jogged on the second day. (3.5 miles jogged in total so far)

On the third day he jogged 1.5 miles more than the last day:

1.5 + 1.5 = 3 (6.5 miles jogged so far)

9.25 total miles were jogged, meaning that we will need to subtract 6.5 from 9.25 to get the answer:

9.25 - 6.5 = 2.75 miles jogged on the fourth day

The quarterly payment will be $1,127.86

Compound interest is the interest on a loan or deposit that  levied on both the first principal and the collected interest from past periods.

The amortization formula is ...

\(A=\dfrac{P\timesr}{(1-(1+r)^{-n}}\)

where A is the payment amount, P is the principal amount, r is the interest rate per period, and n is the number of periods.

Here, we have

P=$16,231, r=0.051/4=0.01275, n=4·4=16.

By reversing the order of integration, the given integral ∫30∫3ysin\((x^2)\) dxdy becomes ∫\(03∫0√(30y) sin(x^2) dydx.\)

When reversing the order of integration, we first consider the limits of integration for the new integral.

The original limits for y are from 0 to 3, and the limits for x are from 0 to √(30y). Therefore, the new limits for y are from 0 to 3, and the new limits for x are from 0 to √(30y).

Next, we rearrange the integral to integrate with respect to y first. We integrate sin(\(x^2)\)with respect to x while treating y as a constant. The antiderivative of sin\((x^2)\)does not have a closed-form expression, so we leave it as is.

Finally, we integrate the result from the first integration with respect to y, using the limits 0 to 3. This will give us the final value of the integral.

The values of m for which\(y = e^mx\) is a solution of \(y" - 4y' - 5y = 0\) are m = -1 and 4.

The equation y" - 4y' - 5y = 0 is a second order linear homogeneous differential equation with constant coefficients. The solution of this equation is given by the general form of the solution as \(y = e^mx\), where m is the root of the characteristic equation m2 - 4m - 5 = 0, which can be solved by the quadratic formula as m = 2 and 3 or m = -2 and -3.

To solve this equation, we expand the quadratic equation as,

m2 - 4m - 5 = 0

m2 - 5m + m - 5 = 0

(m - 5)(m + 1) = 0

Therefore, the two roots of this equation are m = 5 and -1.

Now, we plug in these two roots in the solution of the differential equation, \(y = e^mx\).

For m = 5,

\(y = e^(5x)\)

For m = -1,

\(y = e^(-x)\)

Therefore, the values of m for which \(y = e^mx\) is a solution of y" - 4y' - 5y = 0 are m = -1 and 4.

To determine the probability that neither card shows an even number with replacement, we need to calculate the probability of drawing an odd number on each card and multiply the probabilities together.

Let's assume we have a standard deck of 52 playing cards, where half of them are even numbers (2, 4, 6, 8, 10) and the other half are odd numbers (1, 3, 5, 7, 9).

Since the cards are replaced after each draw, the probability of drawing an odd number on each card is 1/2. Therefore, the probability that neither card shows an even number is:

P(neither card shows an even number) = P(odd on card 1) * P(odd on card 2) = 1/2 * 1/2 = 1/4

So, the probability that neither card shows an even number, with replacement, is 1/4.

Answer:

m<8 = 46°

Step-by-step explanation:

m<2 = m7 (alternate exterior angles are congruent)

Substitute

3x + 53 = 7x - 55

Collect like terms

3x - 7x = -53 - 55

-4x = -108

Divide both sides by -4

-4x/-4 = -108/-4

x = 27

m<8 + m<7 = 180° (linear pair angles)

Substitute

m<8 + 7x - 55 = 180°

Plug in the value of x

m<8 + 7(27) - 55 = 180

m<8 + 189 - 55 = 180

m<8 + 134 = 180

Subtract 134 from each side

m<8 = 180 - 134

m<8 = 46°

The distribution of the sample mean can be represented as: X ~ N(67.15, 3.084/√30)

The distribution of the sample mean is a normal distribution with a mean equal to the population mean µ and a standard deviation equal to the population standard deviation σ divided by the square root of the sample size n.

Therefore, for this problem, the distribution of the sample mean can be represented as:

X ~ N(67.15, 3.084/√30)

where X is the sample mean, N represents a normal distribution, 67.15 is the population mean, 3.084 is the population standard deviation, and √30 is the square root of the sample size.

This distribution assumes that the sample is randomly selected from the population and the sample size is large enough to satisfy the central limit theorem.
