To solve the quadratic equation x² - 5x + 6 = 0, we can use the Quadratic Formula. The correct solutions for x can be determined by substituting the coefficients into the formula and simplifying.

The Quadratic Formula is used to find the solutions of a quadratic equation of the form ax² + bx + c = 0, where a, b, and c are coefficients. The formula is given by:

x = (-b ± √(b² - 4ac)) / (2a)

For the equation x² - 5x + 6 = 0, we can identify a = 1, b = -5, and c = 6. Substituting these values into the Quadratic Formula:

x = (-(-5) ± √((-5)² - 4(1)(6))) / (2(1))

= (5 ± √(25 - 24)) / 2

= (5 ± √1) / 2

= (5 ± 1) / 2

Simplifying further, we get two possible solutions for x:

x₁ = (5 + 1) / 2 = 6 / 2 = 3

x₂ = (5 - 1) / 2 = 4 / 2 = 2

Therefore, the solutions for x in the quadratic equation x² - 5x + 6 = 0 are x = 3 and x = 2. Comparing these solutions to the given options, we can see that the correct answer is b. x = 2, 3.

The linear programming problem involves maximizing the objective function P = 70x + 80y subject to the following constraints: 2x + y ≤ 16, x + y ≤ 10, x ≥ 0, and y ≥ 0.

To solve the problem, we first sketch the feasible region defined by the constraints and identify its vertices. Then, we evaluate the objective function at each vertex to find the maximum value of P.

To sketch the feasible region, we plot the lines 2x + y = 16 and x + y = 10 on a coordinate plane. The feasible region is the region that satisfies the inequality constraints, which is the intersection of the shaded regions below and above these lines, respectively. The feasible region is a triangle with vertices at (0,0), (0,10), and (8,8).

Next, we evaluate the objective function P = 70x + 80y at each vertex of the feasible region:

P(0,0) = 70(0) + 80(0) = 0

P(0,10) = 70(0) + 80(10) = 800

P(8,8) = 70(8) + 80(8) = 1440

The maximum value of P is 1440, which occurs at the vertex (8,8). Therefore, the solution to the linear programming problem is P = 1440.

The values of aj to a10 can be determined by repeatedly using the given recurrence relation an = 1 + alali, starting with ao = 0. Furthermore, when n = 4m, it can be shown that an = (log n).

To find the values of aj to a10, we can use the given recurrence relation, an = 1 + alali, along with the initial condition ao = 0. By repeatedly applying the recurrence relation, we can calculate the values of aj step by step. Starting with ao = 0, we substitute the value of ao into the relation to find a1: a1 = 1 + a0lal0 = 1 + 0lal0 = 1. Continuing this process, we substitute the values of aj-1 into the relation to calculate aj for j = 2 to 10.

Now, let's consider the special case where n = 4m. In this case, we want to show that an = (log n). When n = 4m, we can rewrite it as [tex]n = 2^{(2m)[/tex]. By taking the logarithm of both sides, we obtain [tex]log n = log(2^{(2m)})[/tex]. Using the logarithmic property, we can simplify this to log n = 2mlog 2. Since log 2 is a constant value, we can represent it as a constant k. Therefore, log n = 2mk. Comparing this with the expression an = (log n), we can see that an = 2mk. Thus, when n = 4m, an = (log n) holds true.

In summary, the values of aj to a10 can be found by repeatedly applying the given recurrence relation. Additionally, when considering the special case where n = 4m, it can be shown that an = (log n).

Yorktown Savings Bank can expect to save approximately $1,444,400 in net losses by following the decision rule of granting credit cards only to customers scoring more than 40 points.

To calculate the expected savings in net losses, we need to determine the number of bad accounts that would be avoided by applying the decision rule and multiply it by the average account balance of those accounts.

The total number of customers who scored 40 points or less and resulted in a loss is 7,665, representing 30% of all customers. On the other hand, 12% of good customers, which amounts to 3,066 customers, also scored 40 points or less.

By applying the decision rule of granting credit cards only to customers scoring more than 40 points, we can estimate the number of bad accounts that would be avoided as 30% of the customers who scored 40 points or less, i.e., 0.3 * 3,066 = 920.

The average account balance of the bad accounts is $6,200. Multiplying this by the number of accounts avoided, we find that the expected savings in net losses would be approximately $1,444,400.

Therefore, the final answer is:h(t) = (t+2)e^(-t) - 2te^(-t) - 2.

Explanation:

H(s) = 1 / s^4 + 2s³ + s²

From the Laplace transform pair table, the Laplace transform of t^n is given by:

n! / s^(n+1)

Therefore, taking the inverse Laplace transform of H(s), we get:

h(t) = L^(-1) [1 / s^4 + 2s³ + s²]

h(t) = L^(-1) [1 / s^2(s^2 + 2s + 1)]

h(t) = L^(-1) [1 / s^2(s + 1)^2]

The inverse Laplace transform of 1/s^2 is given by t.The inverse Laplace transform of

1/(s+1)^2

is given by e^(-t) * t.So, the inverse Laplace transform of

H(s) is

h(t) = t * e^(-t) + 2 * e^(-t) - 2t * e^(-t)h(t) = (t+2)e^(-t) - 2te^(-t) + constant. Applying the initial condition

h(0) = 0:0 = (0+2) - 0 + constant = -2h(t) = (t+2)e^(-t) - 2te^(-t) - 2

To find h(t), we first need to take the inverse Laplace transform of H(s). Using partial fraction decomposition, we can break H(s) down into a sum of simpler fractions. We then use the inverse Laplace transform pairs table to obtain the inverse Laplace transform of each fraction. Finally, we add up all the inverse Laplace transforms to obtain h(t). In this particular problem, the inverse Laplace transform of H(s) is given by

(t+2)e^(-t) - 2te^(-t) - 2.

Therefore, the final answer is:h(t) = (t+2)e^(-t) - 2te^(-t) - 2.

The least squares line of best fit for the given points (0,1), (2,0), (3,1), and (3,2) is y = 0.3x + 0.7.

To find the least squares line of best fit, we need to minimize the sum of the squared vertical distances between the observed y-values and the corresponding predicted y-values on the line.

We can start by calculating the mean values of x and y, which are (2, 1) respectively. Next, we calculate the deviations from the mean for both x and y for each data point.

The deviations for x are (-2, 0, 1, 1), and for y they are (0, -1, 0, 1).

Then, we calculate the product of these deviations for each point (-20, 0(-1), 10, 11) and sum them up to get the numerator of the slope formula, which is 1.

Next, we calculate the square of the deviations for x for each point (4, 0, 1, 1) and sum them up to get the denominator of the slope formula, which is 6.

The slope of the line is obtained by dividing the numerator by the denominator, giving us 1/6 or approximately 0.17.

Finally, we use the point-slope form of a line to find the y-intercept. Using the point (2, 1) and the slope, we can solve for the y-intercept, which is approximately 0.7.

Thus, the equation of the least squares line of best fit for the given points is y = 0.3x + 0.7.

The solution to the given first-order ordinary differential equation (ODE) is y(t) = e^(t^3/3) - 1. This solution satisfies the initial condition y(0) = 0.

To verify that the solution y(t) = e^(t^3/3) - 1 is indeed correct, we can substitute it back into the original ODE and check if it satisfies the equation as well as the initial condition.

Starting with the solution y(t) = e^(t^3/3) - 1, we can differentiate it with respect to t:

dy/dt = d/dt (e^(t^3/3) - 1)

= (1/3)e^(t^3/3) * (d/dt)(t^3) - 0

= (1/3)e^(t^3/3) * 3t^2

= t^2 * e^(t^3/3)

Now we can compare this with the right-hand side of the original ODE, which is t^2 + t^2y:

t^2 + t^2y = t^2 + t^2(e^(t^3/3) - 1)

= t^2 + t^2e^(t^3/3) - t^2

= t^2e^(t^3/3)

We observe that both sides are equal, thus verifying that y(t) = e^(t^3/3) - 1 is a valid solution to the given ODE.

Furthermore, when we substitute t = 0 into the solution, we get y(0) = e^(0/3) - 1 = e^0 - 1 = 1 - 1 = 0, which satisfies the initial condition y(0) = 0. Therefore, the solution y(t) = e^(t^3/3) - 1 is correct for the given ODE.

Applying the tangent sum formula, we find the exact value of the expression to be (tan(1/4π + 2/3π))/(1 - tan(1/4π)tan(2/3π)).

To find the exact value of the expression Tan(5/4π - 1/3π) using the sum/difference identities, we can utilize the tangent difference formula, which states that tan(A - B) = (tan(A) - tan(B))/(1 + tan(A)tan(B)).

Using the tangent difference formula, we can rewrite the given expression as tan(5/4π) - tan(1/3π) divided by 1 + tan(5/4π)tan(1/3π).Let's break down the evaluation of the expression step by step. First, we'll focus on finding the individual tangent values of the angles involved.

For tan(5/4π), we know that the tangent function is positive in the second and fourth quadrants. The reference angle is 5/4π - π = 5/4π - 4/4π = 1/4π. In the second quadrant, the tangent value is positive, so tan(5/4π) = tan(1/4π). Similarly, for tan(1/3π), we find the reference angle by subtracting the nearest multiple of π, which is 3/3π = π. The reference angle is 1/3π - π = -2/3π. The tangent function is positive in the first and third quadrants, so tan(1/3π) = tan(-2/3π). Now, we can substitute these values into the expression: (tan(1/4π) - tan(-2/3π))/(1 + tan(1/4π)tan(-2/3π)).

To evaluate the tangent values, we can use the identity tan(-θ) = -tan(θ), which gives us tan(-2/3π) = -tan(2/3π). Combining these substitutions, the expression becomes (tan(1/4π) + tan(2/3π))/(1 - tan(1/4π)tan(2/3π)). At this point, we can utilize the tangent sum formula, which states that tan(A + B) = (tan(A) + tan(B))/(1 - tan(A)tan(B)). By comparing this formula to our expression, we can identify that A = 1/4π and B = 2/3π. Applying the tangent sum formula, we find the exact value of the expression to be (tan(1/4π + 2/3π))/(1 - tan(1/4π)tan(2/3π)). This is the simplified exact value of the given expression using the sum/difference identities.

An increase in real income does not affect velocity, an increase in the nominal interest rate decreases velocity, and an increase in the price level increases velocity. The real money demand is 5,000.

To find the real money demand, we substitute the given values into the money demand function: M = 5,000 + 0.2(1,000) - 1,000(0.10) = 5,000 + 200 - 100 = 5,100. The nominal money demand is simply M = 5,000 + 0.2(1,000) - 1,000(0.10) = 6,000. The velocity is given by V = Y/M = 1,000/6,000 = 6.

When the price level doubles to P = 200, the real money demand remains the same since it depends on real variables only. So the real money demand is still 5,000. The nominal money demand becomes M = 5,000 + 0.2(1,000) - 1,000(0.10) = 12,000. The velocity remains the same at V = Y/M = 1,000/12,000 = 6.

An increase in real income does not affect the money demand equation directly, so velocity remains unchanged. An increase in the nominal interest rate reduces the demand for money and leads to a decrease in velocity. An increase in the price level increases the nominal money demand, which in turn increases velocity since velocity is inversely related to the nominal money demand.

Please provide the target stock price to proceed with the calculation and obtain the target FCF at the end of year 1.

To determine the target Free Cash Flow (FCF) at the end of year 1, we need to calculate the FCF for each year based on the given growth rates and other financial information.

Let's break down the calculations step by step:

Calculate the FCF for year 1 using the expected growth rate of 12%:

FCF₁ = FCF₀ * (1 + growth rate) = FCF₀ * (1 + 0.12)

Calculate the FCF for year 2 using the same growth rate:

FCF₂ = FCF₁ * (1 + growth rate) = FCF₁ * (1 + 0.12)

Calculate the FCF for year 3 using the same growth rate:

FCF₃ = FCF₂ * (1 + growth rate) = FCF₂ * (1 + 0.12)

Calculate the FCF for year 4 using the industry growth rate of 5%:

FCF₄ = FCF₃ * (1 + industry growth rate) = FCF₃ * (1 + 0.05)

Given that ABC Co. aims to set the current stock price to $40, we can use the formula for the stock price as a multiple of FCF to determine the target FCF:

Target FCF = Target Stock Price / Stock Price Multiple

To find the stock price multiple, we divide the market value of the company by the FCF:

Stock Price Multiple = Market Value / FCF

The market value can be calculated as follows:

Market Value = (Number of Shares * Stock Price) + Debt - Cash

Substituting the given values:

Market Value = (15 million shares * $40) + $50 million debt - $20 million cash

Finally, we can calculate the target FCF at the end of year 1 using the target stock price and the stock price multiple:

Target FCF₁ = Target Stock Price / Stock Price Multiple

The given logarithmic equation is 5 ln(x) = 20 the exponential function and the natural logarithm are inverse functions, e^(ln(x)) simplifies to x:

x = e^4 This represents a single solution. So, the correct choice is A

To solve this equation, we need to isolate the variable x.

First, divide both sides of the equation by 5:

ln(x) = 4

To eliminate the natural logarithm, we can rewrite the equation in exponential form:

e^(ln(x)) = e^4

Since the exponential function and the natural logarithm are inverse functions, e^(ln(x)) simplifies to x:

x = e^4

Therefore, the solution to the equation is x = e^4. This represents a single solution.

In exact form, the solution set is {e^4}. So, the correct choice is A. The solution set is not empty, and it consists of a single value, which is e^4.

The numerical value of z in the arc of the circle is 25.25.

The sum of the measures of the central angles of a circle with no interior points in common is 360 degree.

Also, centeral equals to the arc.

To determine the value of z, we, sum the given values of the arc and equate to 360 degrees.

From the image:

Arc 1 = z degree

Arc 2 = 54 degree

Arc 3 = 204 degree

Arc 4 = ( 3z + 1 ) degree

Hence:

Arc 1 + Arc 2 + Arc 3 + Arc 4 = 360

Plug in the values:

z + 54 + 204 + ( 3z + 1 )  = 360

Collect and add like terms:

z + 3z + 54 + 204 + 1 = 360

4z + 259 = 360

4z = 360 - 259

4z = 101

z = 101/4

z = 25.25

For the trapezoid:

(a) To calculate the distance from H to D (HD), use trigonometry. We know that BD = 10 km and ∠ABD = 58º. Therefore, sine of ∠ABD equals to HD/BD.

So, HD = BD × sin(∠ABD)

= 10 km × sin(58º)

= 10 km × 0.8480 (rounded value of sin(58))

= 8.48 km

(b) To calculate the length of AD, we'll first calculate HB using the Pythagorean theorem, since ∆HBD is a right triangle:

HB = √(BD² - HD²)

= √((10 km)² - (8.48 km)²)

= √(100 km² - 71.83 km²)

= √(28.17 km²)

= 5.3 km

So, AD = AB - HB

= 12 km - 5.3 km

= 6.7 km

(c) To calculate the angle ∠DAB, use the law of cosines on ∆ABD:

cos(DAB) = (AD² + BD² - DB^2) / 2ADBD

= (6.7 km² + 10 km² - 10 km²) / (2 × 6.7 km × 10 km)

= (44.89 km²) / (134 km²)

= 0.3347

Therefore, ∠DAB = arccos(0.3347) = 70.46°.

(d) Given that the actual length of AD = 6.7 km, the landowner's estimate was 11.5 km. The absolute error is the difference between the estimated and actual value:

Absolute Error = |Estimated - Actual|

= |11.5 km - 6.7 km|

= 4.8 km

The percentage error is the absolute error divided by the actual value, multiplied by 100:

Percentage Error = (Absolute Error / Actual) × 100

= (4.8 km / 6.7 km) × 100

= 71.64%

(e) The volume V of a cone is given by the formula V = (1/3)πr²h. Given that the radius r = 20 cm = 0.2 m and height h = 40 cm = 0.4 m:

V = (1/3) × π × (0.2 m)² × 0.4 m

= 0.0084 cubic meters

(f) To calculate the total volume of concrete needed, know the number of bollards. The bollards are installed every 100 m along the perimeter of the plot. The perimeter P of a trapezoid is the sum of its sides:

P = AB + BC + CD + DA

= 12 km + BC + 8 km + 6.7 km

BC = √(BD² - CD²) = √((10 km)² - (8 km)²) = √(36) = 6 km (Using Pythagorean theorem).

So, P = 12 km + 6 km + 8 km + 6.7 km = 32.7 km = 32700 m

The number of bollards is P/spacing = 32700 m / 100 m/bollard
