Using synthetic division, P(a)= 9.

To find P(a) using synthetic division and the remainder theorem, we will substitute the value of a into the polynomial p(x) = x^3 + 4x^2 - 5x + 6 and perform synthetic division.

First, let's set a = 2 and write the polynomial as p(x) = x^3 + 4x^2 - 5x + 6. Now, we set up the synthetic division table:

2 | 1 4 -5 6

|_____________

1 6 7 9

The numbers in the first row of the table are the coefficients of the polynomial p(x), and the second row represents the result after each step of the synthetic division. The number at the bottom right corner, 9, is the remainder.

According to the remainder theorem, P(a) is equal to the remainder when p(x) is divided by (x - a). In this case, a = 2, so P(2) is equal to the remainder, which is 9.

Therefore, P(2) = 9.

In summary, using synthetic division and the remainder theorem, we find that P(2) for the polynomial p(x) = x^3 + 4x^2 - 5x + 6 is equal to 9.

The value of p is -3.

To rewrite the equation 2x² + 12x = -13 in the form 2(x - p)^2 + q = 0, we need to complete the square. Let's go through the steps:

2x² + 12x = -13

First, let's move the constant term to the right side:

2x² + 12x + 13 = 0

Next, divide the equation by the leading coefficient (2) to simplify:

x² + 6x + 6.5 = 0

To complete the square, we take half of the coefficient of x (6) and square it to get 9.

Then, we add and subtract 9 to the equation:

x² + 6x + 9 - 9 + 6.5 = 0

(x + 3)² - 3² + 6.5 = 0

(x + 3)² - 9 + 6.5 = 0

(x + 3)² - 2.5 = 0

Comparing this equation with 2(x - p)² + q = 0, we can see that p = -3 and q = -2.5.

Therefore, the value of p is -3.

Step-by-step explanation:

48 minutes is equivalent to 1/5 of 4 hours.

We have,

To express 48 minutes as a fraction of 4 hours, we need to convert both the minutes and hours into a common unit of time.

Since there are 60 minutes in an hour, we can convert 4 hours to minutes:

4 hours = 4 x 60 minutes = 240 minutes

Now, we can express 48 minutes as a fraction of 240 minutes:

48 minutes / 240 minutes

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 48:

= 48 minutes / 240 minutes

= 1/5

Therefore,

The coordinates of P' after rotating triangle PQR counterclockwise by 270 degrees about the origin are P'(-3, 1).

To rotate a point counterclockwise about the origin, you can use the following rotation formula:

x' = x * cos(theta) - y * sin(theta)

y' = x * sin(theta) + y * cos(theta)

In this case, we want to rotate the triangle PQR 270 degrees counterclockwise. We can calculate the coordinates of each point after the rotation.

For point P(-1, -3):

x' = (-1) * cos(270°) - (-3) * sin(270°)

y' = (-1) * sin(270°) + (-3) * cos(270°)

We can simplify these equations using the values of cosine and sine for 270 degrees:

x' = (-1) * 0 - (-3) * (-1)

y' = (-1) * (-1) + (-3) * 0

Simplifying further:

x' = 0 - 3

y' = 1 + 0

x' = -3

y' = 1

The area of the shaded region is 61.76 square feet.

The given figure has a rectangle and circle.

Let us find the area of both rectangle and circles.

The length of rectangle is 14 ft and width is 8 ft.

Area = length × width

Using the distributive property which is given as: (a+b) (c+d) = a*c + a*d + b*c + b*d.

To multiply the binomials (2√3x - 2) and (3√3x + 5), we need to apply the distributive property which will result in four different terms.

To determine the number of solutions for the given system of equations:

y = -2x + 5

4y + x - 20 = 0

We can solve the system of equations using various methods such as substitution, elimination, or graphing. Let's solve it using the elimination method:

First, we'll multiply the first equation by 4 to make the coefficients of x in both equations equal:

4y = -8x + 20

4y + x - 20 = 0

Next, we'll subtract equation 1 from equation 2 to eliminate the y term:

(4y + x - 20) - (4y = -8x + 20)

This simplifies to:

x = 0

Now, we substitute this value of x back into the first equation to find the value of y:

The value of y is 48.

To find the value of y in this scenario, we need to use the fact that the angle bisector of ∠JSL splits it into two congruent angles.

Let's denote one of these congruent angles as ∠HSL and the other as ∠LSJ. Since ∠JSL is bisected, we have:

m∠JSL = m∠HSL + m∠LSJ

Given that m∠JSL = (4y - 10)° and m∠HSL = m∠LSJ = ∠HSJ = (y + 43)°, we can substitute these values into the equation:

4y - 10 = (y + 43) + (y + 43)

Simplifying the equation:

4y - 10 = 2y + 86

Subtracting 2y from both sides:

2y - 10 = 86

Adding 10 to both sides:

2y = 96

There are 5040 different passwords that can be created from the word "Alabama" when using all the letters.

To calculate the number of different passwords that can be created from the word "Alabama," we need to consider the total number of permutations.

The word "Alabama" contains 7 letters. To find the number of different passwords, we need to calculate the number of permutations of these 7 letters.

The formula to calculate permutations is given by:

nPr = n! / (n - r)!

Where n is the total number of items (letters in this case), and r is the number of items selected (length of the password).

For the word "Alabama," let's assume we want to create passwords of length 7, using all the letters.

n = 7 (number of letters in "Alabama")

r = 7 (length of the password)

Using the formula, we can calculate the number of permutations:

7P7 = 7! / (7 - 7)!

= 7! / 0!
