Answer:

46.47¢

Step-by-step explanation:

Since in the image above angle 3 is 79 degrees, angle 11 is also equal to 79 degrees based on the vertical angles theorem.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The vertical angles theorem is also referred to as vertically opposite angles theorem and it states that two (2) opposite vertical angles that are generally formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other.

In Geometry, when two (2) parallel lines are cut by a transversal, the interior angles that are formed on the same side of the transversal are supplementary angles, which makes:

Angle 3 = Angle 14

Angle 14 = Angle 9

Angle 3 ≅ Angle 9 (Congruent angles or supplements of the same angle)

By applying the vertical angles theorem, we have:

Angle 9 ≅ Angle 11 = 79 degrees.

Step-by-step explanation:

The successive approximations are x_1 = 1.2900, x_2 = 1.2898, and x_3 = 1.2898.

So, the method yields a positive root of the polynomial 5 + 4x - 6 to be x = 1.2898 (rounded to 5 decimal places). The number 22 and 23 are not relevant to this problem.

To use Newton's method to find the positive root of the polynomial 5 + 4x - 6, we need to use the following iteration formula:

x_(n+1) = x_n - f(x_n)/f'(x_n)

where f(x) = 5 + 4x - 6 and f'(x) = 4.

Starting with x_0 = 1.32, we have:

x_1 = x_0 - f(x_0)/f'(x_0) = 1.32 - (5 + 4(1.32) - 6)/4 = 1.2900
x_2 = x_1 - f(x_1)/f'(x_1) = 1.2900 - (5 + 4(1.2900) - 6)/4 = 1.2898
x_3 = x_2 - f(x_2)/f'(x_2) = 1.2898 - (5 + 4(1.2898) - 6)/4 = 1.2898

The successive approximations are x_1 = 1.2900, x_2 = 1.2898, and x_3 = 1.2898.

So, the method yields a positive root of the polynomial 5 + 4x - 6 to be x = 1.2898 (rounded to 5 decimal places). The number 22 and 23 are not relevant to this problem.

```public static int getDaysToReachID(long id) { double salary = 0.001; int days = 0; while (salary < id) { salary *= 2; days++; } return days; }```

Explanation:

The given problem can be solved by using a while loop which continues until the salary becomes at least as large as the given ID.

The number of days required to reach the given salary can be calculated by keeping track of the number of iterations of the loop (i.e. number of days).

The initial salary is given as 0.001 AED and it gets doubled every day.

Therefore, the salary on the n-th day can be calculated as:

0.001 * 2ⁿ

A while loop is used to calculate the number of days required to reach the given ID. In each iteration of the loop, the salary is doubled and the number of days is incremented.

The loop continues until the salary becomes at least as large as the given ID. At this point, the number of days is returned as the output.

1 standard deviation =  8 inches. the answer is OPTION E

We know that 99.7% of American men have heights between 5'0" and 7'0". Since height is normally distributed, we can use the empirical rule to estimate the standard deviation.

According to the empirical rule, 99.7% of the data falls within 3 standard deviations of the mean. Therefore, we can say that the range of heights from 5'0" to 7'0" is 3 standard deviations.

We can use this information to estimate the standard deviation as follows:

Range of heights = 7'0" - 5'0" = 2 feet

3 standard deviations = 2 feet

1 standard deviation = 2/3 feet

1 foot = 12 inches

Therefore, 1 standard deviation = 2/3 * 12 inches = 8 inches

So, our estimate of the standard deviation of the height of American men is 8 inches. Therefore, the answer is OPTION E in the given options.
