Through linear programming, we find out that the number of cartons of food is 360 cartons and the number of cartons of clothing is 550 cartons.

It is given to us that -

Each carton of food will feed 11 people

Each carton of clothing will help 4 people

Each 20-cubic-foot box of food weighs 40 pounds

Each 5-cubic-foot box of clothing weighs 20 pounds

The total weight per carrier cannot exceed 23,000 pounds

The total volume must be no more than 9000 cubic feet

We have to find out the number of cartons of food and clothing should be sent with each plane shipment to maximize the number of people who can be helped.

Let us say that -

The number of cartons of food = x

The number of cartons of clothing = y

According to the given information, the constraints on weight and size can be represented as -

Constraints on weight:

[tex]40x+20y\leq 23000\\= > 20y\leq 23000-40x\\= > 20y\leq -40x+23000\\= > y\leq -2x+1150[/tex]------ (1)

Constraints on size:

[tex]20x+5y\leq 9000\\= > 5y\leq 9000-20x\\= > 5y\leq -20x+9000\\= > y\leq -4x+1800[/tex]----- (2)

We also know that

[tex]x\geq 0[/tex] and [tex]y\geq 0[/tex]

The equation for the help that will be provided with each carton of food and clothing can be represented as -

[tex]11x+4y[/tex] ---- (3)

From equation (1), for weight graph, we have

[tex]y\leq -2x+1150[/tex]

For [tex]x=0[/tex], [tex]y\leq 1150[/tex]

For [tex]y=0, x\leq 575[/tex]

[tex]y\leq -4x+1800[/tex]

For [tex]x=0, y\leq 1800[/tex]

For [tex]y=0, x\leq 450[/tex]

For (0,1150), the equation (3) becomes

[tex]11x+4y[/tex]

[tex]= 11*0+4*1150\\= 4600[/tex]

For (360, 550), the equation (3) becomes

[tex]11x+4y\\= 11*360 + 4*550\\= 6160[/tex]

For (450,0), the equation (3) becomes

[tex]11x+4y\\= 11*450 + 4*0\\= 4950[/tex]

The length and width of the rectangular plot that will maximize the area are 50 feet and 25 feet respectively.

The vertex (maximum) of this equation is equal to 1,250 square feet.

Mathematically, the area of a rectangle can be calculated by using this formula:

A = lw

Where:

Since one side of this rectangular plot along the river does not require fencing, the perimeter equation is given by:

P = 2(l + w)

100 = 2w + l      

Making length the subject of formula, we have:

l = 100 - 2w

Therefore, the area of this rectangular plot would now be:

A = (100 - 2w)w

A = 100w - 2w²

Next, we would take the first derivative and equate to zero in order to obtain the maximum area:

dA/dw = 100 - 4w

0 = 100 - 4w

4w = 100

Width, w = 25 feet.

For the length of this rectangular plot, we have:

Length, l = 100 - 2w

Length, l = 100 - 2(50)

Length, l = 50 feet.

Now, we can find the vertex (maximum) of this equation is given by:

Maximum area = 50 × 25

Maximum area = 1,250 square feet.

The speed of the raft was 2.86 km/hr.

Speed is defined as the rate of change of position of an object in any direction.

Given that, a patrol boat with speed of 12 km/hr caught a raft after travelling for 20 km and patrol boat left the dock after 5 hours and 20 minutes the raft left,

The time taken by the patrol boat to catch the raft is;

t = 20/15 = 5/3 hours

5/3 hours = 1 hour 40 minutes

Thus, it took 1 hour 40 minutes for the patrol boat to catch the raft

Thus, the raft was travelling for 5 hours 20 minutes plus 1 hour 40 minutes which 7 hours,

The speed of raft = 20/7 = 2.86 km/hr

Answer: 9

Step-by-step explanation:

The ratio of two outputs for any two input values that are 2 units apart is

27

Ratio refers to fractions of two numbers say a and b written in the form

a / b

The problem involves dividing the output for the larger x-value by the output or the smaller x-value

choosing output for x = 3 and x = 6, the two values are 2 units apart

the outputs are y = 27 and y = 729 respectively

taking the ratios

= 729 / 27

dividing gives the lowest term of the fraction

Where a complex number, where a,b are real numbers and i = √-1.

Given,

Here we have the following complex number expression

(_ + _i) (_ + _i) = 34 + 8i

Here we need find the value of the dashes and the number must lies between -9 to +9.

Let us consider a, b, c and d as the number presented in the dashes then it can be written as,

=> (a + bi) (c + di)

Now, we have to expand this expression then we get,

=> ac + adi + bci + bdi²

Combine the like terms,

=> (ac − bd) + (ad + bc)i

Now, we have to match the coefficients as,

30 < ac − bd < 80

We also know that,

=> ad + bc = 0

Now, we need to pick four integers between -9 and 9 such that these two equations are satisfied.  

We also know that

=> ac − bd = 34

=> ad + bc = 8

Therefore, it makes sense to assume b is negative.  

After some trial and error, one possible answer is a = 5, b = -6, c = 2, d = 4

From the question, we are to determine the slope of the given equation.

The given equation is

8x + 3y = 8 – 2x

To determine the slope of the line, we will express the equation in the general form of the slope-intercept form of the equation a line.

The general form of the slope-intercept form of a line is

y = mx + b

Where m is the slope

and b is the y-intercept

Expressing the equation in the slope-intercept form of a line

8x + 3y = 8 - 2x

Subtract 8x from both sides of the equation

8x - 8x + 3y = 8 - 2x - 8x

3y = 8 - 10x

3y = -10x + 8

Divide through by 3

The statement which is true about the graph representing function h is the graph is positive on the intervals (- ∞, - 8) and (- 4, 3). Option D is correct.

We are given;

h(x) = -x^3 - 9x^2 + 4x + 96

The function is a cubic function.

Since the leading coefficient is negative the graph start from second quadrant.

So, the graph must be positive in the second quadrant.

Let us check the option D;

The graph is positive on the intervals (- ∞ , - 8) and (- 4, 3).

The graph is positive in the second quadrant. So, (- ∞ , - 8) satisfy.

Let's choose any point between -4 to 3 and substitute in the given equation.

Put x = -1 in the given equation;

h(x) = -(-1)^3 - 9(-1)^2 + 4(-1) + 96 = 1 - 9 - 4 + 96 = 84

So, h(x) is positive.
