The firm expects replacing around 734 batteries out of the 32,200 produced.

using the normal distribution formula z = (x - )

When z denotes the z-score,

x denotes the battery life of interest, is the mean battery life, and is the standard deviation.

For x = 100, use the z-score: z = (100 - 120) / 10 z = -2

Calculate the area under the normal curve to the left of z = -2.

0.0228 is the approximate value.

The number of batteries expected to be replaced by the manufacturer is equal to the proportion of batteries with a battery life of less than 100 hours multiplied by the total number of batteries produced:

Number of batteries to be replaced = 0.0228 x 32,200

Answer: To calculate the amount of money you will have in the account after 40 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where A is the amount of money in the account after t years, P is the principal (the initial amount of money deposited), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.

In this case, P = $2000, r = 0.02 (since the interest rate is 2%), n = 12 (since the interest is compounded monthly), and t = 40. Plugging these values into the formula, we get:

A = 2000(1 + 0.02/12)^(12*40)

A = $5,837.85

So you will have $5,837.85 in the account after 40 years.

The guests in the birthday party ate 33 cookies.

We know that Mrs. Smith made 6 1/4 dozen cookies and there were 3 1/2 dozen cookies left.

Let's first convert these fractions to a common denominator of 4, so we can easily subtract them.

6 1/4 dozen = 25/4 dozen

3 1/2 dozen = 14/4 dozen

Now we can subtract the number of cookies that were left from the number of cookies that were made:

25/4 - 14/4 = 11/4 dozen

To find out how many cookies this represents, we need to multiply by the number of cookies in one dozen.

There are 12 cookies in one dozen, so:

11/4 x 12 = 33

Total stored energy = (1/625) ∞

Voltage, also known as electric potential difference, is the measure of the electric potential energy per unit of charge in an electric circuit. It is the force that drives the electric charge in a circuit, similar to how pressure drives water through a pipe. Voltage is measured in volts (V) and is usually represented by the symbol "V". Voltage can be either positive or negative, depending on the direction of current flow and the orientation of the voltage source.

A. The voltage across an inductor is proportional to the time derivative of the current through it, according to Faraday's law of electromagnetic induction. This can be expressed mathematically as:

v(t) = L di/dt

where v(t) is the voltage across the inductor, L is the inductance in henries, and di/dt is the time derivative of the current through the inductor.

In this case, we have [tex]v(t) = 8e^{(-4t)[/tex] V and L = 250 H. Integrating both sides of the above equation with respect to time gives:

∫v(t) dt = L ∫di/dt dt

∫[tex]8e^{(-4t)} dt = 250[/tex] ∫di/dt dt

[tex]-2e^{(-4t)[/tex]= 250i(t) + C

where C is the constant of integration. We can assume that the initial current is zero, so at t = 0, i(0) = 0. This means that C = -2. Substituting this into the equation above, we get:

[tex]-2e^{(-4t)[/tex]= 250i(t) - 2

Solving for i(t), we get:

i(t) = (2/250) [tex]- (2/250)e^{(4t)[/tex]

B. The power absorbed by an inductor is given by:

P = i² R

where P is the power, i is the current, and R is the resistance of the circuit. In an ideal inductor, the resistance is zero, so the power absorbed is also zero.

However, the energy stored in an inductor can be calculated using the following formula:

E = 1/2 L i²

where E is the energy stored, L is the inductance, and i is the current.

In this case, we have L = 250 H and i(t) = (2/250) [tex]- (2/250)e^{(4t)[/tex]Substituting these values into the above equation, we get:

E = 1/2 (250) [(2/250) [tex]- (2/250)e^{(4t)]^2[/tex]

Simplifying this expression, we get:

E = (1/625) [tex]- (2/625)e^{(4t)[/tex]+ (2/625)e^(8t)

To determine the total stored energy, we need to integrate this expression over the interval 0 to infinity, since the voltage and current are given for all values of t. This gives:

Total stored energy = ∫E dt from 0 to infinity

Total stored energy = (1/625) ∫1 dt from 0 to infinity[tex]- (2/625) ∫e^{(4t)[/tex]dt from 0 to infinity + (2/625) ∫e^(8t) dt from 0 to infinity

Total stored energy = (1/625) ∞ [tex]- (2/625) [1/4 e^{(4t)][/tex]from 0 to infinity + (2/625) [1/8 e^(8t)] from 0 to infinity

Since the integrals involving exponential functions go to infinity as t goes to infinity, these terms become zero. Therefore, we are left with:

Total stored energy = (1/625) ∞

which is an infinite value. This is because the energy stored in an inductor is not finite, but rather is dependent on the magnetic field generated by the inductor, which can extend infinitely far.

Answer: 20.64 miles.

Step-by-step explanation: The assignment of nomenclature to the location of the boat's initiation as point A, the termination of the first course of the excursion as point B, and the termination of the second course of the journey as point C is proposed. The present study reveals that the spatial positioning of point A and point B is separated by a distance of precisely 15 miles in an eastward direction. Similarly, point B and point C are separated by a distance of 15 miles, but oriented along the vector of N 20° E.

The application of trigonometry provides a means to determine the spatial separation between point B and point C. Based on computations, the distance from point B to point C has been estimated to be approximately 7.83 miles along the northward direction and approximately 14.16 miles along the eastward direction.

Henceforth, the computation of the distance between point A and point C (i.e., the prevailing separation of the boat from the pier) can be determined by the ensuing method:

The mathematical expression denoting the distance between points A and C, designated as AC, is given by the square root of the sum of the squares of the distances between points A and B, designated as AB, and between points B and C, designated as BC. In formulaic notation, this can be expressed as AC = √((AB)² + (BC)²).

The magnitude of the distance denoted by AC, between two points A and C, can be calculated using the Euclidean distance formula, which involves the square root of the sum of the squares of the differences between the corresponding coordinates of the two points. In this particular case, the calculation results in the expression √(15² + 14.16²).

The distance between points A and C, denoted as AC, can be expressed mathematically as the square root of the sum of the squares of the horizontal and vertical distances between them. Thus, AC = √(225 + 200.89), where 225 and 200.89 represent the square of the horizontal and vertical distance, respectively. This equation can be simplified to yield the measurement of the physical distance between points A and C in the applicable units of length.

The distance between points A and C is determined to be the square root of 425.89 in units of length.

The measurement of the distance between point A and point C is approximately equivalent to 20.64 miles.

Answer: Graph A.

Step-by-step explanation:

A. not continuous

Continuous functions have no jumps or vertical asymptotes.

Continuity

For a function to be continuous, each point on the function must be defined. This means that there cannot be points on the graph where there is no value or coordinate point. Additionally, all points must be connected by the graph. Sudden jumps in the graph that are not connected by anything are not continuous.

Determining Continuity

The graph above is not continuous. We know this for 2 reasons. Firstly, the graph is not defined at x = -3. Since there is an open circle at x = -3, the value is not defined. Thus, the function cannot be considered continuous. Additionally, there are multiple jumps. At x = -3, the function suddenly jumps to x = -2 without the points being connected. The same thing happens again at x = 1. This also shows that the graph is not continuous.

The proof that f(2x)=3f(x)+1/f(x)+3 is shown below.

To show that f(2x) = 3f(x) + 1/f(x) + 3, we substitute 2x for x in the expression for f(x):

f(x) = x - 1 / x + 1

f(2x) = 2x - 1 / 2x + 1

Next, we substitute x into the expression for f(x) and add the result to itself twice:

f(x) = x - 1 / x + 1

f(x) + f(x) + f(x) = (x - 1 / x + 1) + (x - 1 / x + 1) + (x - 1 / x + 1)

= 3x - 3 / 3x + 3

We can simplify the expression by dividing both the numerator and denominator by 3:

f(x) + f(x) + f(x) = x - 1 / x + 1

= (1/3) (3x - 3) / (1/3) (3x + 3)

= (x - 1) / (x + 1)

= f(x)

Now, we substitute f(x) and f(2x) back into the original equation:

f(2x) = 2x - 1 / 2x + 1

3f(x) + 1/f(x) + 3 = 3(x - 1 / x + 1) + 1/(x - 1 / x + 1) + 3

= (3x - 3 / x + 1) + (1 / (x - 1 / x + 1)) + 3

= (3x - 3 + (x + 1) / (x - 1)) / (x + 1)

= (2x + 2) / (x + 1)

= 2(x + 1) / (x + 1)

= 2

Thus, we have shown that f(2x) = 3f(x) + 1/f(x) + 3.
