The area of a rectangle is the product of its length and breadth. The maximum area enclosed by the fence is 36800 square meter  and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.

A rectangle is a type of parallelogram that has equal diagonals.

All the interior angles of a rectangle are equal to the right angle.

The diagonals of a rectangle do not bisect each other.

The dimensions of the given rectangle is (650 - 2x) and x.

Then, the area of the given rectangle is A(x)  = x(650 - 2x)

In order to find the maximum area enclosed take the derivative of A(x) and equate it to zero as follows,

(660 - 2x) - 2x = 0

=> 4x = 660

=> x = 660 / 4

=> x = 115

Now, the maximum area is the value of A(x) at x = 115 as below,

= 115 × (650 - 2×115)

= 115 × 320

= 36800

The dimensions for the maximum area are 115 and (650 - 2 × 115) = 320.

Hence, the largest area enclosed is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width labeled in the figure is given as 115 meter.

The inequalities which represent relationships between the number of doubles (x) and amount of gospels (y) are x + y ≤ 11,7x + 4y ≥ 56 and y ≥ 3.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given,

No more than 11

Given that:

- The seeds cost is 40$ per acre for corn.

- The seeds cost is 30$ per acre for soybeans.

- The farmer wants to spend no more than $2400.

• Let be "x" the number of acres of seeds for corn and "y" the number of acres of seeds for soybeans.

You know that the total amount of money has to be less than or equal to $2400. Therefore, you can write the following Linear Inequality to represent that situation:

You can rewrite it in another form by solving for "y":

Since the number of acres cannot be negative:

• You can identify that the boundary line is:

It is written in Slope-Intercept Form:

Where "m" is the slope and "b" is the y-intercept.

In this case, you can identify that the y-intercept is:

In order to find the x-intercept, substitute this value of "y" into the equation and solve for "x" (because the y-value is zero when the line intersects the x-axis):

Then, you get:

You can identify that the symbol of the inequality is:

It indicates that the line must be solid and the shaded region must be below the boundary line.

Knowing all this information, you can graph the inequality on the Coordinate Plane (Remember that the values of the variables must be greater than or equal to zero. Then, you must shade with a different color the region in which "x" and "y" are greater than or equal to zero).

Hence, the answer is:

- Linear Inequality:

- Nonnegative restrictions:

- Graph:

The coordinates of the y-intercept of the function is (0, 2)

The equation of the function is given as

f(x) = 2(3)x

The equation is an exponential function

So, we need to represent it properly

The equation of the function is:

f(x) = 2(3)ˣ

Next, we set the x-coordinate to 0

So, we calculate the y-intercept

f(0) = 2(3)⁰

Evaluate the equation

f(0) = 2

What is an Area?

An object's Area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

According to the question,

Length = (2x+1) cm

Width = 12 cm

To solve , the Area of the rectangle = length x width i.e.

less than 108 cm^2

length x width = (2x+1) x 12 cm

Area < 108 cm^2

The equation of the linear function in slope intercept form is  y = 2x -6

The equation of a line in slope intercept form can be represented as follows:

y = mx + b

where

Therefore, let's find the slope of the linear function using (0, -6)(1, -4).

m = -4 + 6 / 1 - 0

m = 2 / 1

m = 2

Therefore, the y-intercept of the linear function can be calculated using (0, -6) and the lope.

y = 2x + b

-6 = 2(0) + b

b = -6

Here's how:

 t2-140

 —————— • 20 = 0 • 20

   20  

Now, on the left hand side, the  20  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

iii. Now, we see that the term in parenthesis can be rewritten as a square:

iv. Finally, we rewrite the term inside and outside the parenthesis as:

Second point

We find a second point by evaluating the function f(x) in x = 1, we get:

The coordinates of the second point are (1, -15).

Graph

We have the following points of the parabola:

Using these points and taking into account that the axis of symmetry is x = -1 (because the x-coordinate of the vertex is -1), we get the following graph:

Coordinates of the vertex: (-1, -27)

Coordinates of the second point: (1, -15)

We solve as follows:

The rate of change at point A on the graph below for the y-axis in relation to the x-axis is -0.5.

The term "rate of change" (ROC) describes the rate at which something changes over time.

Thus, it is not the number of individual changes themselves but rather the acceleration or deceleration of changes (i.e., the rate).

The rate of change is a tool used in finance to comprehend price returns and spot trend momentum.

Other instances of changing rates are as follows: 40 more rats are added to the colony every week.

So, the rate of change is:

The point is given at 1.5 with respect to the y-axis.

And we can clearly see that it has been decreased to 1 with respect to the y-axis.

So, the rate of change:

1.0 - 1.5 - = -0.5

Therefore, the rate of change at point A on the graph below for the y-axis in relation to the x-axis is -0.5.

The distance between Kenya and the accident = 500 feet

The  rule of thumb for the reaction distance = 1 ft per mile per hour of speed

The rule of thumb expressed as an equation is therefore;

Distance traveled during the reaction time = 1 × v

Where;

v = The speed of driving

The distance Kenya traveled before reacting is therefore;
