**Maximum Area with a given perimeter:**

The rectangle with the maximum area, given the perimeter of 'P' units, the length and width would be 'P / 4' units each.

To find the length and width of a rectangle that has a given perimeter and a maximum area, we can utilize the concept that a square has the maximum area for a given perimeter. This means that if the perimeter is fixed, the maximum area will be achieved when the rectangle is a square.

Let's apply this concept to the given exercises:

11. Perimeter: 80 meters

If the perimeter is 80 meters, and we want to find the dimensions (length and width) of a rectangle with the maximum area, we can consider it as a square.

Since a square has all sides equal, let's assume the length of each side of the square as 's'. The perimeter of a square is given by 4s.

Given that the perimeter is 80 meters, we have:

4s = 80

Simplifying the equation:

s = 80 / 4

s = 20

Therefore, the length and width of the rectangle with the maximum area, given the perimeter of 80 meters, would be 20 meters each.

12. Perimeter: P units

In this case, the perimeter is given as 'P' units. Similarly, we can apply the same concept and assume the length and width of the rectangle as 'x' units.

The perimeter of a rectangle is given by the formula: 2(length + width).

Given that the perimeter is 'P', we have:

2(length + width) = P

Simplifying the equation:

length + width = P / 2

Since we want to find the maximum area, we can consider the length and width to be equal, as in a square.

So, we have:

2x = P / 2

x = P / 4

Therefore, for the rectangle with the maximum area, given the perimeter of 'P' units, the length and width would be 'P / 4' units each.

In both exercises, the maximum area is achieved when the rectangle is a square (for a given perimeter), with all sides equal to one-fourth of the perimeter.

Step-by-step explanation:

You can count the squares, or ...

Any way you do this, there are 35 square, so the area is 35 square centimeters.

The given polynomial function has 1 relative minimum and 1 relative maximum.

The given function is

f(x) = 2x³ - 2x² + 1

derivating the above function,

f'(x) = 6x² - 4x

At slope = 0, f'(x) = 0 (for maximum and minimum values)

⇒ 6x² - 4x = 0

⇒ 2x(3x - 2) = 0

2x = 0 or 3x - 2 = 0

∴ x = 0 or x = 2/3

Then the y-coordinates are calculated by substituting these x values in the given function,

when x = 0;

f(0) = 2(0)³ - 2(0)² + 1 = 1

So, the point is (0, 1)

when x = 2/3;

f(2/3) = 2(2/3)³ - 2(2/3)² + 1 = 19/27

So, the point is (2/3, 19/27)

Since y = 1 is the largest value, the point (0, 1) is the relative maximum for the given function.

So, y = 19/27 is the smallest value, the point (2/3, 19/27) is the relative minimum for the given function.

Zach's work is correct because the total of the partial product is the ratio of the dividend

The ratio of any two integers is expressed as a/b

Given the ratio 124.8 : 24 = 5.2. This means that the quotient, if 128.8 is divided by 24 is 5.2

Taking the ratio;

124.8: 24

= 124.8/24

The average distance of electric cars is 275.

The range of the data set is 300.

Given:

To find: Average distance of electric cars

Solution:

The average distance of electric cars can be calculated by finding the average of the data set containing the distances of electric cars. Let's assume that the data set is as follows:

250, 250, 250, 400, 300, 300, 350, 100

To find the average distance of electric cars, we can use the formula:

Average = (Sum of all the data points) / (Number of data points)

Substituting the given values, we get:

Average = (250 + 250 + 250 + 400 + 300 + 300 + 350 + 100) / 8

Average = 2200 / 8

Average = 275

Therefore, the average distance of electric cars is 275.

Now, let's calculate the range of the data set. The range is the difference between the maximum and minimum values in the data set. From the given data set, we can see that the minimum value is 100 and the maximum value is 400.

Range = Maximum value - Minimum value

Range = 400 - 100

Range = 300

Therefore, the range of the data set is 300.

We have proved both implications, we can conclude that 4 divides (m^2 * n^2) if and only if m and n are both even.

To prove that 4 divides (m^2 * n^2) if and only if m and n are even, we need to prove two implications:

If 4 divides (m^2 * n^2), then m and n are even.

If m and n are even, then 4 divides (m^2 * n^2).

Let's start with the first implication:

If 4 divides (m^2 * n^2), then m and n are even.

We can prove this by contrapositive. Assume that m and n are not both even, which means that at least one of them is odd. Without loss of generality, let's assume that m is odd. Then m can be written as m = 2k + 1, where k is an integer. Substituting this into the expression for m^2 * n^2, we get:

m^2 * n^2 = (2k + 1)^2 * n^2

= 4k^2 * n^2 + 4kn^2 + n^2

Note that the first two terms in this expression are both divisible by 4, but the last term (n^2) is not necessarily divisible by 4, since n could be odd. Therefore, m^2 * n^2 is not divisible by 4 if m and n are not both even. This proves the contrapositive, and hence the first implication.

Now, let's move on to the second implication:

If m and n are even, then 4 divides (m^2 * n^2).

We can prove this directly. Since m and n are even, we can write them as m = 2k and n = 2j, where k and j are integers. Substituting these into the expression for m^2 * n^2, we get:

m^2 * n^2 = (2k)^2 * (2j)^2

= 4k^2 * 4j^2

= 16(k^2 * j^2)

Since k and j are integers, k^2 * j^2 is also an integer, and hence 16(k^2 * j^2) is divisible by 4. Therefore, m^2 * n^2 is divisible by 4 if m and n are both even. This proves the second implication.

Since we have proved both implications, we can conclude that 4 divides (m^2 * n^2) if and only if m and n are both even.

 profit in each item will be 2.5

Answer:

20%

Step-by-step explanation:

Let's say that the 10 items cost $1 each. That would mean you spend $10.

As of that, the cost of 8 items (selling price) is also $10, meaning that you would spend $1.20 to buy the item

($1.20 - $1)/($1) = .20/1 = 1/5 = 20%

The age of Ricardo is 15 years while his mother after 15 year is 55 years. The combined saving is $120.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another.

16)

Suppose Ricardo's current age is R and his mother is M.

As per the given,

R/M = 3/8 → R = (3/8)M

After 15 years, (R + 15)/(M + 15) = 6/11

11R + 165 = 6M + 90

6M - 11R = 75

6M - 11(3/8)M = 75

M = 40 years

R = (3/8)40 = 15 years

a) Ricardo age is 15 year

B) Age of the mother after 15 years will be 40 + 15 = 55 years.

17)

Let's say Owen's saving is O while Luca's is L.

O/L = 4/3 → O = (4/3)L

(O + 120)/(L + 60) = 8/5

5O + 600 = 8L + 480

8L - 5O = 120

8L - 5(4/3)L = 120

L = 90

O = (4/3)90 = 120

Combined saving = 90 + 120 = $210

Hence "The age of Ricardo is 15 years while his mother after 15 years is 55 years. The combined saving is $120".

The given statement "The this pointer is not automatically passed to static member functions of a class." is false as static member functions can be called without creating an object of the class, and the "this" pointer is used to refer to the current instance of the class. Since no instance is required for static member functions, the "this" pointer is not applicable in this case.

In object-oriented programming, a class is a blueprint for creating objects, and member functions are functions defined within a class that can be called on objects of that class.

Static member functions, also known as class methods, are special member functions that are associated with the class itself rather than any specific object or instance of the class. They are declared using the "static" keyword.

Since static member functions do not operate on specific instances of the class, they do not have access to the "this" pointer. The "this" pointer is a hidden pointer that points to the current object instance, allowing non-static member functions to access the data members and other member functions of the object. However, static member functions do not have this pointer because they are not tied to any specific object.

Static member functions can only access static members of the class, which include static variables and other static member functions. They can be called using the class name itself, without creating an instance of the class. This is because they are not associated with any particular object but rather with the class as a whole.
