To find g(-2), we'll substitute -2 for x in the equation g(x) = -4x² - 5x + 9. So,g(-2) = -4(-2)² - 5(-2) + 9g(-2). The value of g(-2) is -6.

To find g(-2), substitute -2 for x in the equation

g(x) = -4x² - 5x + 9 to get

g(-2) = -6 + 9g(-2)

We are given three functions as follows:

f(x) = (1/3)x - 5, g(x)

= -4x² - 5x + 9, and

h(x) = 1/(x - 8) + 3.

We are asked to find g(-2), which is the value of g(x) when x = -2.

Substituting -2 for x in the equation g(x) = -4x² - 5x + 9, we get

g(-2) = -4(-2)² - 5(-2) + 9.

This simplifies to g(-2) = -16 + 10 + 9 = -6.

Hence, g(-2) = -6.

We start by replacing a=1/4, b=0 and c=-5/6 on both sides of a x (b + c) = (a×b) + (a+c) and compare results

So in 1/4 x (0 + (-5/6)) we solve first the parenthesis (0 + (-5/6))=(-5/6)

Now we solve the product 1/4×(-5/6) = -5/24

Now we replace in the other side

(1/4 × 0) + (1/4 × (-5/6))

First parenthesis: (0) + (-5/24) = -5/24

We conclude that both sides are equal to -5/24! So the property verifies

Step-by-step explanation:

$171.84 is the total estimated cost for the job.

Given that,

The flat rate for our service = $9.50 per hour.

To calculate the total estimate for a job estimated to take 16 hours,

Use the following equations:

For the first 8 hours;

⇒ Total cost = (flat rate + 15% of flat rate) x 8

                     = (9.50 + (0.15 x 9.50)) x 8

                     = 11.03 x 8

                     = $88.24

For the next 8 hours:

⇒ Total cost = (flat rate + 10% of flat rate) x 8

                     = (9.50 + (0.10 x 9.50)) x 8

                     = 10.45 x 8

                     = $83.60

The total estimation for the job is the sum of the costs from the two equations,

⇒ $88.24 + $83.60 = $171.84

So, the total estimate for the job is $171.84

The value of expression cos (A - B)  is,

cos (A - B) = (4√2 - √5) / 9

We have to given that;

sin A = 1/3 where A terminates in Quadrant 1,

And , cos B = 2/3, where B terminates in Quadrant 4.

Since, We know that;

sin² A + cos² A = 1

(1/3)² + cos²A = 1

cos²A = 1 - 1/9

cos²A = 8/9

cos A = 2√2/3

And, We know that;

sin² B + cos² B = 1

(2/3)² + sin²B = 1

sin²B = 1 - 4/9

sin²B = 5/9

sin B = √5/3

Hence, We get;

cos (A - B) = cos A cos B + sin A sin B

Substitute all the values, we get;

cos (A - B) = 2√2/3 x 2/3  + 1/3 x √5/3

cos (A - B) = 4√2/9 - √5/9

cos (A - B) = (4√2 - √5) / 9

The formula predicting the number of US billionaires in any given year (t) is:f(t) = 17.2t - 34,129. We can assume a linear growth model on the based of given information.

The given data states that in the year 1985, there were 13 US billionaires. Whereas in 1990, there were 99 US billionaires. We have to find out the formula that predicts the number of US billionaires in any given year (t).

The yearly increase remains constant, so we can consider the formula for the linear function.f(t) = mt + b

where

t is the year and f(t) is the number of US billionaires in that year (t).

m is the slope of the line and b is the y-intercept.

The slope of the line is given by the formula:m = (y₂ - y₁) / (x₂ - x₁)

Let's plug in the given values to find the slope of the line.m = (99 - 13) / (1990 - 1985)m = 86 / 5m = 17.2 .The y-intercept of the line can be found by substituting the values of t and f(t) from any of the given points into the equation of the line.

Let's use the point (1985, 13).f(t) = mt + b => f(1985) =17.2(1985) + b => f(1985) = 34,142 + b =>b = 13 - 34,142 & b = -34,129.

The formula predicting the number of US billionaires in any given year (t) is:f(t) = 17.2t - 34,129

C. set up the LP model in Excel and run Solver to obtain the answer and sensitivity reports.

D. it would not be feasible to deploy buses to Malacca.

E. The revenue would decrease due to the lower number of passengers, while the cost may remain relatively fixed (assuming the breakdowns do not incur additional repair costs).

(a) Three practical assumptions applicable to this particular linear programming (LP) problem could be: Constant demand, Fixed costs and prices, Full utilization of capacity.

Constant demand: The LP model assumes that the demand for Merlion's point-to-point coach services remains constant throughout the planning period. This means that the number of passengers traveling between Singapore and Malaysia is assumed to be consistent.

Fixed costs and prices: The LP model assumes that the costs associated with operating the buses, such as fuel, maintenance, and driver salaries, remain fixed. It also assumes that the ticket prices charged to passengers are constant and do not change based on factors like demand or competition.

Full utilization of capacity: The LP model assumes that all available seats on each bus will be filled by passengers. It does not account for scenarios where there might be empty seats due to insufficient demand or other factors.

(b) LP Model: Decision Variables, Objective Function, Constraints.

Decision Variables:

Let X i represent the number of buses deployed to city i, where i can take values 1 to n (n being the total number of cities in Malaysia).

Objective Function:

Maximize daily profit:

Maximize Profit = ∑(Revenue - Cost)

Constraints:

Capacity constraint for each city:

∑(X i * Seats per Bus) ≤ Total Available Seats

Demand constraint for each city:

X i ≥ Minimum Demand i

Non-negativity constraint:

X i ≥ 0 for all i

(c) Solution using Excel Solver:

Please provide the following information:

Total available seats

Seats per bus

Minimum demand for each city

Revenue and cost data

With the given input, I can help you set up the LP model in Excel and run Solver to obtain the answer and sensitivity reports.

(d) To determine the profit per passenger required for buses to be deployed to Malacca, we need to consider the revenue and cost associated with each passenger. Let's assume the revenue per passenger is R and the cost per passenger is C.

The profit per passenger can be calculated as follows:

Profit per Passenger = Revenue per Passenger - Cost per Passenger

To deploy buses to Malacca, the profit per passenger should be at least equal to zero or positive. If the profit per passenger is negative, it means that the cost per passenger is higher than the revenue per passenger, resulting in a loss for each passenger. In such a case, it would not be feasible to deploy buses to Malacca.

(e) If two buses were to break down on a given day, it would impact Merlion's profit because there would be a reduction in the number of available buses to transport passengers. This could result in a lower revenue as fewer passengers can be accommodated.

To analyze the impact on profit, you would need to consider the revenue and cost implications of operating with reduced capacity. The revenue would decrease due to the lower number of passengers, while the cost may remain relatively fixed (assuming the breakdowns do not incur additional repair costs).

By estimating the revenue and cost changes based on the reduced capacity, you can compare the new profit with the original profit to determine the impact.

To determine the equation of the tangent plane and normal line of the given curve at the point P(2, -3, 18), we need to find the partial derivatives of the function f(x, y, z) = x^2 + y^2 - 2xy - x + 3y - z - 4.

Taking the partial derivatives with respect to x, y, and z, we have:

fx = 2x - 2y - 1

fy = -2x + 2y + 3

fz = -1

Evaluating these partial derivatives at the point P(2, -3, 18), we find:

fx(2, -3, 18) = 2(2) - 2(-3) - 1 = 9

fy(2, -3, 18) = -2(2) + 2(-3) + 3 = -7

fz(2, -3, 18) = -1

The equation of the tangent plane at P is given by:

9(x - 2) - 7(y + 3) - 1(z - 18) = 0

Simplifying the equation, we get:

9x - 7y - z - 3 = 0

To find the equation of the normal line, we use the direction ratios from the coefficients of x, y, and z in the tangent plane equation. The direction ratios are (9, -7, -1).Therefore, the equation of the normal line passing through P(2, -3, 18) is:

x = 2 + 9t

y = -3 - 7t

z = 18 - t

the area of the rectangle is easy : 15×25 = 375

the right-angled triangle on the long side has one side = 5, and the "invisible" side is 25 - 12 - 5 = 8.

these 2 sides are hitting each other in a right angle and can therefore be used as baseline and height of the triangle.

the area of a triangle is baseline×height/2.

so, the area of the this triangle is 8×5/2 = 20.

the right-angled triangle on the right short side has one side = 5, and the "invisible" side is 15 - 10 = 5.
