The final result of long division is: 9x - 11 with the remainder -12.

To divide (9x² - 21x - 20) by (x - 1) using long division:

To divide using long division, follow these steps:

Step 1: Write the problem in long division format. Place the dividend, which is 9x² - 21x - 20, inside the long division symbol. Place the divisor, which is x - 1, on the left side.

        _______________________
x - 1  |   9x² - 21x - 20

Step 2: Divide the first term of the dividend (9x²) by the first term of the divisor (x). Write the quotient above the long division symbol.

        _______________________
x - 1  |   9x² - 21x - 20
         9x

Step 3: Multiply the quotient (9x) by the divisor (x - 1) and write the result below the dividend. Subtract this result from the dividend.

        _______________________
x - 1  |   9x² - 21x - 20
         9x² - 9x

                - (9x² - 9x)
        _______________________
x - 1  |   9x² - 21x - 20
         9x² - 9x
        ________________
                    -12x - 20

Step 4: Bring down the next term of the dividend (-20) and continue the process.

Using the common factor we found that at the start of the week, there were 800 fiction books and 2000 non-fiction books

Let's assume that at the start of the week, the number of fiction books is 2x, and the number of non-fiction books is 5x, where x is a common factor.

According to the given information, at the end of the week, 20% of each type of book was sold. This means that 80% of each type of book remains unsold.

The number of fiction books unsold is 0.8 * 2x = 1.6x, and the number of non-fiction books unsold is 0.8 * 5x = 4x.

We are also given that the total number of unsold books is 2240. Therefore, we can set up the following equation:

1.6x + 4x = 2240

Combining like terms, we get:

5.6x = 2240

Dividing both sides by 5.6, we find:

x = 400

Now we can substitute the value of x back into the original ratios to find the number of each type of book at the start:

Number of fiction books = 2x = 2 * 400 = 800

Number of non-fiction books = 5x = 5 * 400 = 2000

Therefore, at the start of the week, there were 800 fiction books and 2000 non-fiction books

To write an equation for the concentration of carbon monoxide as a function of time, we can use a sinusoidal function. Since the data reaches a maximum of 30 ppm at 6:00pm and a minimum of 100 ppm at 6:00am, we know that the function will have an amplitude of (100 - 30)/2 = 35 ppm and a midline at (100 + 30)/2 = 65 ppm.

The general equation for a sinusoidal function is:

C(t) = A * sin(B * (t - C)) + D

where:
- A represents the amplitude,
- B represents the period,
- C represents the horizontal shift, and
- D represents the vertical shift.

In this case, the amplitude (A) is 35 ppm and the midline is 65 ppm, so D = 65.

To find the period (B), we need to determine the time it takes for the function to complete one cycle. Since the maximum occurs at 6:00pm and the minimum occurs at 6:00am, the time difference is 12 hours. Therefore, the period (B) is 2π/12 = π/6.

The horizontal shift (C) is determined by the time at which the function starts. Assuming midnight is t=0, the function starts 6 hours before the maximum at 6:00pm. Therefore, C = -6.

Combining all the values, the equation for the concentration of carbon monoxide as a function of time (t) in hours is:

C(t) = 35 * sin((π/6) * (t + 6)) + 65

The equation of the locus of P is y² - 2xy + (k² + 2k - 18)x + (k² + 4k) - 9 = 0.

Consider a point P(x, y) on the locus of P, which is equidistant from point A(3, k) and the straight line L: y = -3.

The perpendicular distance from a point (x, y) to a straight line Ax + By + C = 0 is given by |Ax + By + C|/√(A² + B²).

The perpendicular distance from point P(x, y) to the line L: y = -3 is given by |y + 3|/√(1² + 0²) = |y + 3|.

The perpendicular distance from point P(x, y) to point A(3, k) is given by √[(x - 3)² + (y - k)²].

Now, as per the given problem, the point P(x, y) is equidistant from point A(3, k) and the straight line L: y = -3.

So, |y + 3| = √[(x - 3)² + (y - k)²].

Squaring on both sides, we get:

y² + 6y + 9 = x² - 6x + 9 + y² - 2ky + k²

Simplifying further, we have:

y² - x² + 6x - 2xy + y² - 2ky = k² + 2k - 9

Combining like terms, we get:

y² - 2xy + (k² + 2k - 18)x + (k² + 4k) - 9 = 0

Hence, the required equation of the locus of P is given by:

y² - 2xy + (k² + 2k - 18)x + (k² + 4k) - 9 = 0.

Thus, The equation of the locus of P is y² - 2xy + (k² + 2k - 18)x + (k² + 4k) - 9 = 0.

The value of X in this is approximately 35.6981.

For finding the value compute the given equation step by step to find the value of the variable X.

Start with the equation: X + [(-80) + 54] = 24×(-80) + X×54.

Now, let's compute the expression within the square brackets:

(-80) + 54 = -26.

Putting this result back into the equation, we get:

X + (-26) = 24×(-80) + X×54.

Here, we can compute the right side of the equation:

24×(-80) = -1920.

Now the equation becomes:

X - 26 = -1920 + X×54.

Confine the variable, X, and we'll get the X term to the left side by minus X from both sides:

X - X - 26 = -1920 + X×54 - X.

This gets to:

-26 = -1920 + 53X.

Here,  the constant term (-1920) to the left side by adding 1920 to both sides:

-26 + 1920 = -1920 + 1920 + 53X.

The present value of the installment plan is approximately $2,939,487.33. The winner should choose the one-time payment of $1,800,000 instead.

The present value of the installment plan, we need to determine the current value of the future cash flows, taking into account the 8% annual interest rate. Each annual installment of $200,000 is received over a period of 20 years.

Using the formula for calculating the present value of an ordinary annuity, we have:

Present Value = Annual Payment × [1 - (1 + interest rate)^(-number of periods)] / interest rate

Plugging in the values, we get:

Present Value = $200,000 × [1 - (1 + 0.08)^(-20)] / 0.08

Present Value ≈ $2,939,487.33

The present value of the installment plan is approximately $2,939,487.33.

In this case, the one-time payment option is $1,800,000. Comparing this amount to the present value of the installment plan, we can see that the present value is significantly higher. Therefore, the winner should choose the one-time payment of $1,800,000 instead of the installment plan. By choosing the one-time payment, the winner can immediately receive a larger sum of money and potentially invest it at a higher rate of return than the estimated 8% annual interest rate.

The effective interest rate is 0.00%.

To find the effective interest rate, we can use the formula for the present value of an annuity:

PV = P × [(1 - (1 + r)^(-n)) / r]

Where:

PV = present value (loan amount) = $40,140

P = periodic payment = $1,540

r = interest rate per period (quarter) that we want to find

n = total number of periods = 9 years * 4 quarters/year = 36 quarters

Let's solve the equation for r:

40,140 = 1,540 × [(1 - (1 + r)^(-36)) / r]

We can simplify the equation and solve for r using numerical methods or financial calculators. However, since you mentioned that the effective interest rate is 0.00%, it suggests that the loan is interest-free or has an interest rate close to zero. In such a case, the periodic payment of $1,540 is sufficient to settle the loan in 9 years without accruing any interest.

Therefore, the effective interest rate is 0.00%.

The differential equation that represents the vertical velocity of a falling object, subject to air resistance, is given by:

v(t) = gm Cd n (Joca m tanh t dv/dt m)

Where:

g = the acceleration due to gravity = 9.8 m/s^2

m = the mass of the object

Cd = the drag coefficient of the object

ρ = the density of air

A = the cross-sectional area of the object

tanh = the hyperbolic tangent of the argument

d = the distance covered by the object

t = time

To verify the given solution, we first find the derivative of the given solution with respect to time:

v(t) = gm Cd n (Joca m tanh t dv/dt m)

Differentiating both sides with respect to time gives:

dv/dt = gm Cd n (Joca m sech^2 t dv/dt m)

To determine if the points A(3,-1,2), B(2,1,5), C(1,-2,-2), and D(0,4,7) are coplanar, we can use the concept of collinearity. Hence using this concept we came to find out that the points A(3,-1,2), B(2,1,5), C(1,-2,-2), and D(0,4,7) are not coplanar.

In three-dimensional space, four points are coplanar if and only if they all lie on the same plane. One way to check for coplanarity is to calculate the volume of the tetrahedron formed by the four points. If the volume is zero, then the points are coplanar.

To calculate the volume of the tetrahedron, we can use the scalar triple product. The scalar triple product of three vectors a, b, and c is defined as the dot product of the first vector with the cross product of the other two vectors:

|a · (b x c)|

Let's calculate the scalar triple product for the vectors AB, AC, and AD. If the volume is zero, then the points are coplanar.

Vector AB = B - A = (2-3, 1-(-1), 5-2) = (-1, 2, 3)
Vector AC = C - A = (1-3, -2-(-1), -2-2) = (-2, -1, -4)
Vector AD = D - A = (0-3, 4-(-1), 7-2) = (-3, 5, 5)

Now, we calculate the scalar triple product:

|(-1, 2, 3) · ((-2, -1, -4) x (-3, 5, 5))|

To calculate the cross product:

(-2, -1, -4) x (-3, 5, 5) = (-9-25, 20-20, 5+6) = (-34, 0, 11)

Taking the dot product:

|(-1, 2, 3) · (-34, 0, 11)| = |-1*(-34) + 2*0 + 3*11| = |34 + 33| = |67| = 67

Since the scalar triple product is non-zero (67), the volume of the tetrahedron formed by the points A, B, C, and D is not zero. Therefore, the points are not coplanar.

Answer:

time = 101.84 years

Step-by-step explanation:

The formula for compound interest is given by:

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

Thus, we can plug in 35007 for A(t), 2500 for P, 0.026 for r, and 4 for n in the compound interest formula to find t, the time in years (rounded to the nearest hundredth) that it will take for the savings account to reach 35007:

Step 1:  Plug in values for A(t), P, r, and n.  Then simplify:

35007 = 2500(1 + 0.026/4)^(4t)

35007 = 2500(1.0065)^(4t)

Step 2:  Divide both sides by 2500:

(35007 = 2500(1.0065)^4t)) / 2500

14.0028 = (1.0065)^(4t)

Step 3:  Take the log of both sides:

log (14.0028) = log (1.0065^(4t))

Step 4:  Apply the power rule of logs and bring down 4t on the right-hand side of the equation:

log (14.0028) = 4t * log (1.0065)

Step 4:  Divide both sides by log 1.0065:

(log (14.0028) = 4t * (1.0065)) / log (1.0065)

log (14.0028) / log (1.0065) = 4t

Step 5; Multiply both sides by 1/4 (same as dividing both sides by 4) to solve for t.  Then round to the nearest hundredth to find the final answer:

1/4 * (log (14.0028) / log (1.0065) = 4t)

101.8394474 = t

101.84 = t

Thus, it will take about 101.84 years for the money in the savings account to reach $35007

The solution to the equations are

(i) x = 0

(ii) x ≈ 3.032

(i) 12 + 3eˣ + 2 = 15

First, we can simplify the equation by subtracting 14 from both sides:

3eˣ = 3

isolate the exponential term.

eˣ = 1

solve for x by taking natural logarithm of both sides

ln(eˣ) = ln (1)

x = ln (1)

Since ln(1) equals 0, the solution is:

x = 0

(ii) 4ln(2x) = 10

To solve this equation, we'll isolate the natural logarithm term by dividing both sides by 4:

ln(2x) = 10/4

ln(2x) = 2.5

exponentiate both sides using the inverse function of ln,

e^(ln(2x)) = [tex]e^{2.5}[/tex]

2x =  [tex]e^{2.5}[/tex]

Divide both sides by 2:

x = ([tex]e^{2.5}[/tex])/2

Using a calculator, we can evaluate the right side of the equation:

x ≈ 3.032

Therefore, the solution to the equation is:

x ≈ 3.032 (rounded to 3 decimal places)

P(x) = (x + 5 + 7i)(x + 5 - 7i)(x - (2 - √11))(x - (2 + √11))  is the polynomial function that satisfies the given roots -5 - 7i and 2 - √11.

To write a polynomial function P(x) with rational coefficients so that P(x) = 0 has the roots -5 - 7i and 2 - √11, we can use the fact that complex roots always occur in conjugate pairs. This means that if a + bi is a root of a polynomial with rational coefficients, then a - bi must also be a root.

Let's use this information to construct the polynomial. Step-by-step explanation:

The two given roots are -5 - 7i and 2 - √11.

We know that -5 + 7i must also be a root,

since complex roots occur in conjugate pairs.

So the polynomial must have factors of the form(x - (-5 - 7i)) and (x - (-5 + 7i)) to account for the first root. These simplify to(x + 5 + 7i) and (x + 5 - 7i).

For the second root, we don't need to find its conjugate, since it is not a complex number. So the polynomial must have a factor of the form(x - (2 - √11)). This cannot be simplified further, since the square root of 11 is not a rational number. So the polynomial is given by:

P(x) = (x + 5 + 7i)(x + 5 - 7i)(x - (2 - √11))(x - (2 + √11))

To see that this polynomial has the desired roots, let's simplify each factor of the polynomial using the roots we were given

.(x + 5 + 7i) = 0

when x = -5 - 7i(x + 5 - 7i) = 0

when x = -5 + 7i(x - (2 - √11)) = 0

when x = 2 - √11(x - (2 + √11)) = 0

when x = 2 + √11

We can see that these are the roots we were given. Therefore, this polynomial function has the roots -5 - 7i and 2 - √11 as desired.

The solution to the first logarithmic equation is x = 3. The solution to the second logarithmic equation is x = 84.

For the first logarithmic equation, we have: log(5x) = log(2x + 9)

By setting the logarithms equal, we can eliminate the logarithms:5x = 2x + 9 and now we solve for x:

5x - 2x = 9

3x = 9

x = 3

Therefore, the solution to the first logarithmic equation is x = 3.

For the second logarithmic equation, we have: -6 log3(x - 3) = -24

Dividing both sides by -6, we get: log3(x - 3) = 4

By converting the logarithmic equation to exponential form, we have:

3^4 = x - 3

81 = x - 3

x = 84

Therefore, the solution to the second logarithmic equation is x = 84.

The probability of getting a 2 or 1 when rolling a single fair four-sided die is 2/4 or 1/2. There are 4 possible outcomes in total.

When rolling a fair four-sided die, each face has an equal probability of landing face up. Since we are interested in the probability of getting a 2 or 1, we need to determine how many favorable outcomes there are.

In this case, there are two favorable outcomes: rolling a 1 or rolling a 2. Since the die has four sides in total, the probability of each favorable outcome is 1/4.

To calculate the probability of getting a 2 or 1, we add the individual probabilities together:

Probability = Probability of rolling a 2 + Probability of rolling a 1 = 1/4 + 1/4 = 2/4 = 1/2

Therefore, the probability of getting a 2 or 1 is 1/2.

As for the total number of possible outcomes, it is equal to the number of sides on the die, which in this case is 4.

There are 32 integers included in both Set A and Set B.

To find the number of integers included in both Set A and Set B, we need to determine the overlapping range of values between the two sets. Set A contains all integers from 50 to 100 (inclusive), while Set B contains all integers from 69 to 138 (exclusive).

To calculate the number of integers included in both sets, we need to identify the common range between the two sets. The common range is the intersection of the ranges represented by Set A and Set B.

The common range can be found by determining the maximum starting point and the minimum ending point between the two sets. In this case, the maximum starting point is 69 (from Set B) and the minimum ending point is 100 (from Set A).

Therefore, the common range of integers included in both Set A and Set B is from 69 to 100 (inclusive). To find the number of integers in this range, we subtract the starting point from the ending point and add 1 (since both endpoints are inclusive).

Number of integers included in both Set A and Set B = (100 - 69) + 1 = 32.

Therefore, there are 32 integers included in both Set A and Set B.
