Step-by-step explanation:

To find the number of ways that Mary, her three female friends, and her brother Peter can be seated in a row of 10 seats, we can follow these steps:

First, we need to consider the number of ways that the five people can sit together in the row of 10 seats. We can treat these five people as a single unit and arrange them in the row in 5! (5 factorial) ways.

However, since Mary and her friends are all female, we need to account for the number of ways that they can be arranged within this group of five. We can arrange the four women in 4! (4 factorial) ways.

Finally, we need to consider the number of ways that Peter can be seated in one of the remaining seats. Since there are six remaining seats, Peter can be seated in any of these seats in 6 ways.

Therefore, the total number of ways that Mary, her three female friends, and her brother Peter can be seated in the row of 10 seats is:

5! × 4! × 6 = 120 × 24 × 6 = 17,280

So there are 17,280 ways that these five people can be seated in the row of 10 seats, assuming that they all sit next to each other for the first half of the show.

Step-by-step explanation:

we use the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

with the sides being opposite of the angles.

so, we have here now (sin(90) = 1)

b/sin(51) = c/sin(90) = 24/sin(39)

c = 24/sin(39) = 38.1363775... ≈ 38.1

b = 24×sin (51)/sin(38) = 29.63753176... ≈ 29.6

6 to the 15th power

Step-by-step explanation: for exponents with the same base number just add the exponents (example): 3 to the 3rd power looks like this 3 x 3 x 3  but if we add 3 to the firth power, 3 x 3 x 3 x 3 x 3 then the entire thing becomes 3 to the eighth power, 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3

In the function given, the type of discontinuity that exists at x = -3 when b is not equal to 11/6 is a jump discontinuity.

For the function f(x) to be continuous at x = -3, the limit of f(x) as x approaches -3 from both the left and the right must be equal to f(-3). That is:

lim x→-3+ f(x) = f(-3) = lim x→-3- f(x)

Since x < -3 for the second part of the function, we can calculate the left-hand limit as:

lim x→-3- f(x) = -3(-3)² + 5(-3) + 4b(-3) = 9 + (-15) - 12b = -6 - 12b

And the right-hand limit as:

lim x→-3+ f(x) = 3(-3)² - 2b(-3) = 27 + 6b

Therefore, we must have:

-6 - 12b = 27 + 6b

Solving for b, we get:

b = 33/18 = 11/6

So when b = 11/6, the function is continuous at x = -3.

Now let's consider the case where b is not equal to 11/6. In this case, the left-hand limit and right-hand limit are not equal, which means the function has a jump discontinuity at x = -3. The value of the function at x = -3 from the left-hand side is:

f(-3-) = -3(-3)² + 5(-3) + 4b(-3) = 9 - 15 - 12b = -6 - 12b

And the value of the function at x = -3 from the right-hand side is:

f(-3+) = 3(-3)² - 2b(-3) = 27 + 6b

Therefore, the type of discontinuity that exists at x = -3 when b is not equal to 11/6 is a jump discontinuity.

Answer:

15) For a regular polygon of N sides, the measure of one interior angle is:

A = (N -  2)*180°/N

In this case, the figure has 11 sides, then we have N = 11, and the measure of each interior angle will be:

A = (11 - 2)*180°/11

A = 9*180°/11 = 147.27°

Rounding to the first decimal after the decimal point, we get:

A = 147.3°

Then the correct option is B.

16) We know that the length of all the sides of a square is the same.

In the image, we can see that the length of the right side is 4, and the length of the top side is 2x + 4

And those lengths must be the same, then we have the equation:

2x + 4 = 4

subtracting 4 in each side of the equation we get:

2x + 4 - 4 = 4 - 4

2x = 0

The only solution for this equation is x = 0.

Then the correct option is C

The graph of the equation y=2x+1 shows a straight line, or it is a linear equation. When the value of x rises, eventually the value of y rises by twice the rise in x plus one. With a ruler and the specified amount as the starting point, draw a vertical line. From the line across to the -axis, create a horizontal line using a ruler. Look at the value on the -axis.

There are three fundamental ways to graph linear functions. The initial method involves charting points and then tracing a line through them. The second is by using the slope and y-intercept. The identity function f(x)=x is transformed as the third method.

The exact value of sin 5π/12 is (√6 + √2)/4

The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

Angle in trigonometry can be measured in either degree or radian.

π is a measurement in radian which is equivalent to 180° in degrees.

Therefore:

5π/12 = 5 × 180/12

= 75°

Therefore sin5π/12 = sin75°

sin75 = sin( 45+30) = sin45cos30+ cos 45sin30

= 1/√2 × √3/2 + 1/√2 × 1/2

= √3/2√2 + 1/2√2

= (√3+1)/2√2

The balance for each value of n is calculated by using the formula A = P(1 + r/n) ^nt. The rounded balance values are shown in the last column of the table above.

To complete the table and find the balance A if $3100 is invested at an annual percentage rate of 4% for 10 years and compounded n times a year.

The formula for calculating compound interest is as follows:

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

where P represents the principal investment amount, r is the interest rate, n is the number of times the interest is compounded, t represents the time in years, and A represents the total amount, which includes the principal amount and the interest earned.

The table is given below:
\(\begin{array}{|c|c|c|} \hline \text{n} &

\text{A = P(1 + r/n) }^{nt} &

\text{Balance (rounded to nearest cent)} \\ \hline \text{1} &

\text{\$4788.03} \\ \hline \text{2} &

\text{3100(1 + 0.04/2)}^{2*10} &

\text{\$4798.76} \\ \hline \text{4} &

\text{3100(1 + 0.04/4)}^{4*10} &

\text{\$4817.46} \\ \hline \text{12} &

\text{3100(1 + 0.04/12)}^{12*10} &

\text{\$4861.94} \\ \hline \end{array}\)

The balance is obtained by substituting the values of P, r, n, and t into the compound interest formula.

In this case, the investment is $3100, the annual interest rate is 4%, the investment is for 10 years, and n is the number of times the interest is compounded.

Answer:

\(\frac{1}{3}\)x-1

Step-by-step explanation:

(\(\frac{5}{6}\)x-7)-(\(\frac{1}{2}\)x-6) =

The - sign before 6 is turned into a + sign when the bracket is removed because the arithmetic operation before the bracket is - and two - makes the second - turn into a + (It's a rule I can't rlly explain it well but yea)

\(\frac{5}{6}\)x-7-\(\frac{1}{2}\)x+6 = \(\frac{5}{6}\)x-1-\(\frac{1}{2}\)x

-7+6 makes it a -1.

\(\frac{5}{6}\)x-\(\frac{1}{2}\)x-1 = \(\frac{5}{6}\)x-\(\frac{3}{6}\)x-1

To make the denominator of the two fractions the same, I multiplied the second fraction by 3 so that both denominators are 6.

\(\frac{5}{6}\)x-\(\frac{3}{6}\)x-1 = \(\frac{2}{6}\)x-1

After making the denominator the same, I can directly do the equation for the numerators (5-3=2) and keep the denominator the same.

\(\frac{2}{6}\)x-1 = \(\frac{1}{3}\)x-1

Since 2/6 has a common factor which is 2, I can divide both the numerators and denominators so that the fraction can be simplified further into 1/3, its simplest form.
