Answer:

(x+1)^2 + y ^2 = 16

Step-by-step explanation:

center: (-1,0)

radius=4

(x-h)^2 + (y-k)^2 = r^2

(h,k) = center

plug in the center

(x+1)^2 + (y+0) ^2 = r^2

r^2 = (4)^2

r^2=16

(x+1)^2 + y^2 = 16

True. A rational expression is undefined whenever its denominator is zero. This is because division by zero is not defined.

In mathematics, a rational expression is defined as the quotient of two polynomials, where the denominator represents the divisor. When the denominator of a rational expression becomes zero, it results in division by zero, which is undefined. Division by zero is not a valid operation in mathematics, and it leads to an undefined value. Therefore, to determine if a rational expression is undefined, we need to check if its denominator evaluates to zero. If the denominator is zero, the rational expression is undefined. Also there is division by zero, or related concepts in mathematics.

The 99% confidence interval for the true proportion of undergraduate college students with home internet access is: 0.872 ± 0.057 or (0.815, 0.929).

To estimate the true proportion of undergraduate college students (18-23 years) with home internet access, we can use a confidence interval.

The point estimate for the proportion is 157/180 = 0.872. To find the margin of error, we can use the formula:

Margin of error = z* (sqrt(p_hat*(1-p_hat)/n))

where z* is the critical value for the desired confidence level, p_hat is the sample proportion, and n is the sample size.

For a 99% confidence level, the critical value is 2.576. Plugging in the values, we get:

Margin of error = 2.576 * (sqrt(0.872*(1-0.872)/180)) = 0.057

Therefore, the 99% confidence interval for the true proportion of undergraduate college students with home internet access is:

0.872 ± 0.057 or (0.815, 0.929)

This means that we are 99% confident that the true proportion of undergraduate college students with home internet access falls between 0.815 and 0.929.

The measure of the third angle, C, is 30 degrees. So, the correct answer is (c) 30.

Let's assume the three angles of the triangle are A, B, and C, where A, B, and C are measured in degrees.

We know that the sum of the angles in a triangle is 180 degrees. Therefore, we can write the equation:

A + B + C = 180

The obtain of two angles is 150 degrees, we can set up another equation:

A + B = 150

To obtain the measure of the third angle, which we'll call C, we can subtract the sum of the other two angles from 180:

C = 180 - (A + B)

Substituting the value of the sum of two angles (150 degrees), we have:

C = 180 - 150

C = 30

To find the volume of the glass formed by rotating the shaded region about the y-axis, we can use the method of cylindrical shells.

The volume of a solid of revolution using cylindrical shells is given by the integral:

V = ∫[a,b] 2πx * f(x) * dx

In this case, the function representing the curve that forms the inside of the glass is y = x^4/2. We need to find the limits of integration, a and b, which correspond to the x-values where the shaded region begins and ends.

From the graph, it appears that the shaded region begins at x = -1 and ends at x = 1. So, the limits of integration are -1 to 1.

Now, we can calculate the volume of the glass using the integral formula:

V = ∫[-1,1] 2πx * [tex](x^4/2) * dx[/tex]

V = π * ∫[-1,1] [tex]x^5 dx[/tex]

Using the power rule of integration, we integrate x^5:

V = π * [x^6/6] from -1 to 1

V = π * [[tex](1^6/6) - (-1^6/6)][/tex]

V = π * [(1/6) - (1/6)]

V = π * 0

Therefore, the volume of the glass is 0 cubic units.

Solving a set of linear inequalities in several variables is an NP-hard problem, meaning there is no known polynomial-time algorithm to find a satisfying assignment.

Unlike linear equalities, solving a set of linear inequalities in several variables is an NP-hard problem. This means that there is no known polynomial-time algorithm to find a satisfying assignment for all instances of such problems. The complexity arises from the fact that there are infinitely many potential solutions, making it challenging to determine whether a feasible assignment exists or not. To find a satisfying assignment for linear inequalities, algorithms typically use heuristics or approximation techniques that do not guarantee optimality or completeness. Various methods, such as linear programming or constraint satisfaction algorithms, can be employed, but they may have exponential time complexity in the worst case. Therefore, solving a set of linear inequalities generally requires more computational resources and time compared to solving linear equalities.

Step-by-step explanation:

2x = 60° because they are vertically opposite angles.

x=60÷2=30°

(a)  The synchronous reactance of the alternator is 0.001953125 Ω.

The synchronous reactance [tex]X_{s}[/tex] of the alternator can be calculated using the formula:

[tex]X_{s} = (Vt^2) / (3 * VL * S_{base})[/tex]

where [tex]V_{t}[/tex] is the rated line-to-line voltage of the alternator, VL is the rated line-to-neutral voltage of the alternator (which is the same as the rated voltage for a Y-connected alternator), and S_base is the apparent power rating of the alternator (which is equal to the rated power factor of the alternator times the rated apparent power). Substituting the given values, we get:

[tex]X_{s} = (13.5^2) / (3 * 13.5 * 1600) = 0.001953125[/tex] Ω

Therefore, the synchronous reactance of the alternator is 0.001953125 Ω.

(b) The percentage voltage regulation at full-load 0.8 power factor leading is 23.15%.

The percentage voltage regulation (%VR) at full-load 0.8 power factor leading can be calculated using the formula:

%VR = (E - Vl) / Vl * 100%

where E is the generated voltage of the alternator, and Vl is the terminal voltage of the alternator at full-load 0.8 power factor leading. We can assume that the armature resistance and inductance are negligible compared to Xs for this calculation. Using the given values, we first calculate the apparent power S of the load:

S = P / pf = 1280 / 0.8 = 1600 kVA

Since the load is at unity power factor, the current drawn from the alternator is also 1600 A. Therefore, the voltage drop across Xs is:

Vx = Xs * I = 0.001953125 * 1600 = 3.125 V

The generated voltage E is equal to the terminal voltage Vl plus the voltage drop across Xs:

E = Vl + Vx

The percentage voltage regulation is then:

%VR = (E - Vl) / Vl * 100% = (Vl + Vx - Vl) / Vl * 100% = Vx / Vl * 100%

Substituting the given values, we get:

%VR = 3.125 / 13.5 * 100% = 23.15%

Therefore, the percentage voltage regulation at full-load 0.8 power factor leading is 23.15%.

(c) If the %VR value is taken at half-load lagging power factor, it will be higher than the %VR value at full-load 0.8 power factor leading. This is because the load impedance at half-load lagging power factor has a lower magnitude than the load impedance at full-load 0.8 power factor leading, which means that the voltage drop across [tex]X_{s}[/tex] will be a larger fraction of the terminal voltage, resulting in a larger %VR value.

a) The 7th percentile of the bill amounts is given as follows: $80.64.

b) The 62nd percentile of the bill amounts is given as follows: $116.24.

c) The median of the bill amounts is given as follows: $110.14.

We first must use the z-score formula, as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In which:

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, and can be positive(above the mean) or negative(below the mean).

The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure represented by X in the distribution.

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 110.14, \sigma = 20[/tex]

The median is the same as the mean, hence it is given as follows:

$110.14.

The 7th percentile is X when Z = -1.475, hence:

-1.475 = (X - 110.14)/20

X - 110.14 = -1.475 x 20

X = $80.64.

The 62nd percentile is X when Z = 0.305, hence:

0.305 = (X - 110.14)/20

X - 110.14 = 0.305 x 20

X = $116.24.
