The apothem of a regular hexagon is a line segment drawn from the center of the hexagon to the midpoint of any side.The apothem of the regular hexagon is 5.5 inches.

To find the apothem, we can use the formula:

Apothem = (Perimeter) / (2 * (Number of sides))

In this case, the perimeter of the hexagon is given as 66 inches and the number of sides is 6. Plugging these values into the formula, we get:

Apothem = 66 / (2 * 6) = 11 / 2 = 5.5 inches

Therefore, the apothem of the regular hexagon is 5.5 inches. None of the answer choices provided match this value, so none of the options are correct.

It will take Clayton approximately 5.51 years or 66 months for his money to double at an interest rate of 12.6% compounded monthly.

Let's say Clayton has x amount of money he needs to buy a car. But he only has half of it, which is 0.5x.

To find out how long it will take for his money to double at an interest rate of 12.6% compounded monthly, we can use the formula for compound interest:

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

Where:

A = final amount

P = principal (initial amount)

r = interest rate (as a decimal)

n = number of times interest is compounded per year

t = time (in years)

In this case, we want to find t when A = 2P (i.e., when Clayton's money doubles).

So we have:

\(2P = P(1 + 0.126/12)^(12t)\)

Simplifying:

\(2 = (1 + 0.126/12)^(12t)\)

Taking the natural logarithm of both sides:

\(ln(2) = ln[(1 + 0.126/12)^(12t)]\)

Using the logarithmic property that \(ln(a^b) = b ln(a)\):

\(ln(2) = 12t ln(1 + 0.126/12)\)

Dividing both sides by \(12 ln(1 + 0.126/12)\):

\(t = ln(2) / [12 ln(1 + 0.126/12)]\)

Plugging in the values:

\(t = ln(2) / [12 ln(1.0105)]\)

t ≈ 5.51 years

Therefore, it will take Clayton approximately 5.51 years for his money to double at an interest rate of 12.6% compounded monthly.

Rounding to the nearest month, we get:

t ≈ 5.51 years

= 5.51 x 12 months

≈ 66.12 months

t ≈ 66 months

From the given information provided, In a series RCL circuit the frequency of the generator is  approximately 283.7 Hz.

In a series RCL circuit, the resonant frequency is given by:

f = 1/(2π√(LC))

where L is the inductance in henries, C is the capacitance in farads, and π is a mathematical constant approximately equal to 3.14159.

We are given that the resonant frequency is 270 Hz. Let's assume that the capacitance C is known and try to solve for the inductance L:

270 = 1/(2π√(LC))

Simplifying:

2π√(LC) = 1/270

Squaring both sides:

4π²LC = 1/(270²)

Simplifying:

LC = 1/(4π²×270²)

LC = 6.272 x 10⁻⁹

We are also given that at the non-resonant frequency, the ratio of the inductive reactance to the capacitive reactance of the circuit is observed to be 4.93. This means that:

XL / XC = 4.93

where XL is the inductive reactance and XC is the capacitive reactance.

The inductive and capacitive reactances are given by:

XL = 2πfL and XC = 1/(2πfC)

where f is the frequency in Hz.

Substituting XC = 1/(2πfC) and simplifying the ratio:

2πfL / (1/(2πfC)) = 4.93

Multiplying both sides by (2πfC)²:

(2πf)²L = 4.93C

Substituting the value of C we found earlier:

(2πf)²L = 3.94 x 10⁻⁸

Substituting the value of L = 1/(4π²f²C) we found earlier:

(2πf)²/(4π²f²C) = 3.94 x 10⁻⁸

Yes, two samples can have the same range but different means. The range of a dataset is a measure of the spread or dispersion and is determined by the difference between the maximum and minimum values. The mean, on the other hand, represents the average value of the dataset.

To illustrate this concept, let's consider two different samples:

Sample 1: 1, 5, 6, 9, 10

Sample 2: 2, 4, 7, 8, 10

Both samples have a range of 9 (10 - 1).

However, the means of the samples are different. The mean of Sample 1 is

(1 + 5 + 6 + 9 + 10) / 5 = 6.2,

while the mean of Sample 2 is

(2 + 4 + 7 + 8 + 10) / 5 = 6.2.

Despite having the same range, the means differ between the two samples.

The range only considers the extreme values of the dataset, whereas the mean takes into account all values and provides an average measure. It is possible for the individual values within the samples to be distributed differently, resulting in different means, even if the range remains the same.

Therefore, the range and the mean are distinct measures that capture different aspects of the dataset. While it is possible for two samples to have the same range, they can still have different means based on the specific values and their distribution within each sample.

Obviously 1 ≠ -1, so both conclusions cannot be true.

The short answer is that √(ab) = √a √b is always true if a and b are both non-negative integers, but not always true otherwise. The case here is one in which the identity does not apply. "√a" literally means "the positive number such that its square is a". But you're using the convention that √(-1) = i, and i is not a positive number, so this identity does not apply.

The correct result is i ² = -1.

That's not to say that the identity above is always wrong whenever a or b are not non-negative. For example,

√(-25) = √((-1) × 5²) = √(-1) × √(5²) = 5i

Answer:

A dilation is a transformation that changes the size of a figure while keeping its shape the same. In a dilation with a scale factor of 1/2 and the origin as the center of dilation, each point in the figure is moved away from the origin by a factor of 1/2.

To find the new location of point B, we can apply this dilation to the coordinates of point B. Point B is located at (4,10), so we can multiply each coordinate by 1/2 to find the new location.

B'(x',y') = (1/2)(x,y) = (1/2)(4,10) = (2,5)

So the new location of point B, B' is located at (2,5) in the coordinate plane.

               Solving (1) and (2)

               x - 3y = 3

              3x - 9y = 2

              Multiply Eqn (1) by 3,

insert this in equation 2,

\(\rightarrow \sf 3(3+3y) - 9y - 2 = 0\)

\(\rightarrow \sf 7 = 0\)

Thus no solution for x and y in this solution.

(a)The solution to \(y[n]\) with the given initial condition and input sequence is: \[y[n] = \{1, 1.5, 1.75, 1.875, \ldots\}\]

(b) The solution to \(y[n]\) with the given initial conditions and input sequence is: \[y[n] = \left\{\frac{1}{3}, -\frac{1}{18}, \frac{5}{54}, \ldots\right\}\]

(a) To find the solution to \(y[n]\) when \(y[-1]=1\) and \(x[n]=u[n]\), we can recursively apply the given system equation.

Given:

\[y[n] = 0.5y[n-1] + x[n]\]

\(y[-1] = 1\) (initial condition)

\(x[n] = u[n]\) (unit step input)

To solve for \(y[n]\), we can substitute the values and iterate through the equation:

For \(n = 0\):

\[y[0] = 0.5y[-1] + x[0] = 0.5 \cdot 1 + 1 = 1.5\]

For \(n = 1\):

\[y[1] = 0.5y[0] + x[1] = 0.5 \cdot 1.5 + 1 = 1.75\]

For \(n = 2\):

\[y[2] = 0.5y[1] + x[2] = 0.5 \cdot 1.75 + 1 = 1.875\]

And so on...

The solution to \(y[n]\) with the given initial condition and input sequence is:

\[y[n] = \{1, 1.5, 1.75, 1.875, \ldots\}\]

(b) To solve the difference equation \[y[n] = \frac{1}{3}x_1[n] - 0.5y[n-1] + 0.25y[n-2]\] with the given initial conditions \(y[-1]=0\) and \(y[-2]=1\) and the input sequence \(x_1[n]=\left(\frac{1}{3}\right)^n\), we can use a similar iterative approach.

For \(n = 0\):

\[y[0] = \frac{1}{3}x_1[0] - 0.5y[-1] + 0.25y[-2] = \frac{1}{3} - 0.5 \cdot 0 + 0.25 \cdot 1 = \frac{4}{12} = \frac{1}{3}\]

For \(n = 1\):

\[y[1] = \frac{1}{3}x_1[1] - 0.5y[0] + 0.25y[-1] = \frac{1}{3} \cdot \left(\frac{1}{3}\right)^1 - 0.5 \cdot \frac{1}{3} + 0.25 \cdot 0 = \frac{1}{9} - \frac{1}{6} = -\frac{1}{18}\]

For \(n = 2\):

\[y[2] = \frac{1}{3}x_1[2] - 0.5y[1] + 0.25y[0] = \frac{1}{3} \cdot \left(\frac{1}{3}\right)^2 - 0.5 \cdot \left(-\frac{1}{18}\right) + 0.25 \cdot \frac{1}{3} = \frac{1}{27} + \frac{1}{36} + \frac{1}{12} = \frac{5}{54}\]

And so on...

The solution to \(y[n]\) with the given initial conditions and input sequence is:

\[y[n] = \left\{\frac{1}{3}, -\frac{1}{18}, \frac{5}{54}, \ldots\right\}\]

The iteration process can be continued to find the values of \(y[n]\) for subsequent values of \(n\).

It's important to note that in part (b), the input sequence \(x_1[n] = \left(\frac{1}{3}\right)^n\) was used instead of \(x[n]\) to solve the difference equation.

Answer:

See below.

Step-by-step explanation:

a.

x = cost of adult ticket

y = cost of student ticket

cost of adult ticket is twice the cost of a student ticket

x = 2y

number of adult tickets = 64

number of student tickets = 132

cost of all adult tickets = 64x

cost of all student tickets = 132y

cost of all adult and student tickets combined: 64x + 132y

cost of all adult and student tickets combined: 1040

This gives us the equation:

64x + 132y = 1040

b.

Use substitution to solve the system of equations. Since x = 2y, where you see x in the second equation, substitute it with 2y.

64(2y) + 132y = 1040

128y + 132y = 1040

260y = 1040

y = 1040/260

y = 4

x = 2y = 2(4) = 8
