The impedance​ Z, in​ ohms, of a circuit element is defined as the ratio of the phasor voltage​ V, in​ volts, across the element to the phasor current​ I, in​ amperes, through the elements. That​ is, z= v/i. If the voltage across a circuit element is 12+5i volts and the current through the element is 3-2i ​amperes, determine the impedance.

I'm willing to pay up to $1 to play the game. If I get lucky and the coin lands on heads multiple times, I could potentially win more than $1.

The game is quite simple. I start with $1 and then flip a fair coin. If I get heads, I double my winnings and flip the coin again. I will keep flipping the coin until I get tails, at which point the game is over and I collect the money I have won. Depending on how lucky I get, I could potentially win more than $1. Therefore, I am willing to pay up to $1 to play the game. The expected value of this game is $1.50. This is because, on average, I will get heads 50% of the time and tails 50% of the time. So, if I get heads every time, I will double my winnings each time and end up with $2. If I get tails every time, I will end up with $1. Therefore, the expected value is the average of these two outcomes, which is $1.50. There is also some risk involved in this game. If I get unlucky and get tails on my first flip, then I will only get my money back and not make any profit. Therefore, I have to be willing to take on some risk if I want to try and make a profit. It is important to note that this game does not guarantee a profit. The expected value may be $1.50, but I could end up making less or more than that depending on how lucky I get. Therefore, I have to be willing to accept some uncertainty if I want to play this game.

149.0848502 decibels are emitted from a jet plane with a sound intensity of 8.1*10²

Decibels are units for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds.

Number of watts per square meter

d = 10*log(I/IO)

IO = 10⁻¹²

Therefore: d = 10 * log(I/10⁻¹²

jet plane has a sound intensity of 8.1*10² watts per square meter.

Therefore: d = 10*log((8.1*10²) / 10⁻¹²)

10²/10⁻¹² = 10²⁽⁻¹²⁾ = 10⁽²⁺¹²⁾ = 10¹⁴

Therefore: d = 10 * log(8.1 * 10¹⁴)

log(8.1 * 10¹⁴) = 14.90848502

The Lakewood Times had a 30.4% increase in the number of subscribers after it was bought out.

What is the percentage increase?

Percent increase is a way of measuring how much something has increased relative to its original value. It is expressed as a percentage, and it is calculated by taking the difference between the new value and the original value, and then dividing that difference by the original value, and then multiplying by 100.

Formula: % increase = (new value - original value) / original value x 100

To find the percent increase, you can use the formula:

% increase = (new value - old value) / old value x 100

In this case, the percent increase would be:

% increase = (6201 - 4770) / 4770 x 100 = 30.4%

Hence, The Lakewood Times had a 30.4% increase in the number of subscribers after it was bought out.

Let's call the grandmother's current age G and the grandson's current age S.

From the first piece of information given, we know that:

G = S + 48

From the second piece of information given, we know that:

G - 14 = 13S

We can use the first equation to substitute for G in the second equation:

(S + 48) - 14 = 13S

S + 34 = 13S

34 = 12S

S = 34/12

S = 2.8 years

So the grandson is 2.8 years old.

Now we can use this information to find the grandmother's age:

G = S + 48

G = 2.8 + 48

G = 50.8 years

So, the grandmother is 50.8 years old and the grandson is 2.8 years old.

This question involves the binomial probability distribution. The probability of exactly 2 successful outcomes (in this case, visitors who are looking for the website) in 5 trials (visitors to the website) can be calculated using the formula:

P(X = 2) = (5C2)(0.12)^2(0.88)^3

Where C represents the binomial coefficient and 0.12 and 0.88 represent the probability of a successful outcome (looking for the website) and unsuccessful outcome (not looking for the website), respectively.

Calculating this gives:

P(X = 2) = (5C2)(0.12)^2(0.88)^3 = 100.01440.4712 = 0.066

So the probability that, in a random sample of 5 visitors to the website, exactly 2 are looking for the website is 0.066 or about 6.6%.

a) To find the real and imaginary parts of a complex number, we can use the equation z = x + iy, where x is the real part and y is the imaginary part.

To sketch a stem plot, we need to plot the real part on the x-axis, and the imaginary part on the y-axis. For example, for the complex number z = 4 + 3i, the real part is x = 4 and the imaginary part is y = 3. Therefore, the stem plot would be (4, 3).

b) To find the magnitude and phase of a complex number, we can use the equation z = |z|e^(iθ), where |z| is the magnitude and θ is the phase. To sketch a stem plot, we need to plot the magnitude on the x-axis, and the phase on the y-axis. For example, for the complex number z = 4 + 3i, the magnitude is |z| = 5 and the phase is θ = arctan(3/4). Therefore, the stem plot would be (5, arctan(3/4)).

Answer: We can set up a system of equations to represent the given information:

Let x be the number of adult tickets sold

Let y be the number of student tickets sold

x + y = 56 (the total number of tickets sold is 56)

5x + 3y = 232 (the total amount of money made is 232 dollars)

To find the number of adult and student tickets sold, we can use the first equation to solve for one of the variables in terms of the other, and then substitute that into the second equation.

x + y = 56

x = 56 - y

Now we can substitute this value of x into the second equation:

5(56 - y) + 3y = 232

280 - 5y + 3y = 232

280 = 8y

y = 35

So, 35 student tickets were sold, and 56 - 35 = 21 adult tickets were sold.

The converse of the Pythagorean Theorem states that if two sides of a triangle are congruent, then the angles opposite to them are also congruent. This property is known as the Corresponding Angles Postulate.

The Pythagorean Theorem states that the sum of the squares of the lengths of the two sides of a right triangle are equal to the square of the length of the hypotenuse. The theorem is written as a^2 + b^2 = c^2. The converse of the Pythagorean Theorem states that if two sides of a triangle are congruent, then the angles opposite to them are also congruent. This property is known as the Corresponding Angles Postulate.  To prove this postulate, we can start with an arbitrary triangle ABC. If we extend the side AC to D, then we can create a line parallel to BC, creating two similar triangles, ABC and ADC. Since similar triangles have corresponding angles that are congruent, then  angle A = angle D. Since side AC is congruent to side AD, then angle A is also congruent to angle B. This proves the Corresponding Angles Postulate.
