Step-by-step explanation:

The number of centons between each Cylon attack are 21, 23 and 25.

An odd number is a number that is not perfectly divisible by 2. For example, 3 is an odd number because it is not perfectly divisible by 2.

A consecutive number is a number that follows each other on the number line. Consecutive odd numbers are odd numbers that follow each other on the number lines.

Let x represent the first odd number.

The next odd number : x + 2

The third odd number : x + 4

x + (x + 2) + (x + 4) = 75

Add similar numbers: 3x + 6 = 75

3x = 75 - 6

3x = 66

x = 21

The second numbers : 21+ 2 = 23

The third number = 21 + 4 = 25

The dimensions of the deck would be increased by 1 feet.

Area of a rectangle = length x width

Initial area of the deck = 3 x 8 = 24 feet²

Area of the deck when it is increased = (1 + 0.50) x 24  = 36 feet²

Length of the deck after it is increased = 3 + x

Width of the deck after it is increased = 8+ x

Area of the new deck : (3 + x) + (8 + x) = 36

24 + 3x + 8x + x² = 36

x² + 8x + 3x + 24 - 36 = 0

x² + 11x - 12 = 0

The solutions of the quadratic equation are -1 and 12

-1 + x = 0

x = 1

The graph passes through [tex](\frac{1}{3}, -0.3)[/tex]

What is function and graph of a function?

A function from A to B is a rule that maps to each elements of A, a unique element of B.

A is the domain of the function and B is the co-domain of the function.

A collection of all points of the form [tex](x, f(x))[/tex] is called graph of the function.

Here,

[tex]f(x) = 3x - 1.3[/tex]

Putting [tex]x = \frac{1}{3}[/tex]

[tex]f(\frac{1}{3}) = 3 \times \frac{1}{3} -1.3\\[/tex]

       [tex]= 1-1.3\\[/tex]

The fraction of coefficient factor out is 3/8.

What is Fraction?
A fraction is a portion of a whole or, more broadly, any number of equal parts. In everyday English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters. Numerators and denominators are also employed in uncommon fractions such as compound fractions, complex fractions, and mixed numerals. The numerator and denominator of positive common fractions are natural numbers.

The given expression is , 3/8d+3/4

By solving a linear equation, we will see that the points are vertical only if the value of x is -2.

We say that two points (x₁, y₁) and (x₂, y₂) are vertical if the points have the same x-component and different y-component, so we must have:

x₁ = x₂

y₁ ≠ y₂

In this case, the two points are:

F(3-2x, 12) and G(x+9, 7)

The y-component is different, so we only need to have:

3 - 2x = x + 9

This is a linear equation, below I will solve it:

3 - 2x = x + 9

3 - 9 = x + 2x

-6 = 3x

-6/3 = x

-2  =x

The points are vertical if x = -2.

y = 2x² + 4x + 1

Start by differentiating the function

This is done as follows

y' = 4x + 4

Next, we set the differentiated equation to 0

So, we have the following equation

4x + 4 = 0

This gives

4x = -4

Divide by 4

x = -1

Next, we substitute x = -1 in the given equation y = 2x² + 4x + 1

So, we have the following equation

y = 2(-1)² + 4(-1) + 1

The vertex of the given function y = 2x² + 4x+1 is (-1, -1) which is the correct answer would be an option (B).

The function is below given by,

y = 2x² + 4x + 1

Differentiate with respect to x to get the derivative of the above function,

y' = dy/dx = d/dx (2x² + 4x + 1)

y' = 4x + 4

Equating the derivative of the function to zero

y' = 0

4x + 4 = 0

4x = -4

Divide by 4 into both sides of the equation,

x = -1

Substitute x = -1 in the given function y = 2x² + 4x + 1

y = 2(-1)² + 4(-1) + 1

y = 2(1) - 4 + 1

y = -1

The input value x in the function k( x ) = 6x - 12 when k( x ) = 15 is 9/2.

A function is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.

Given the data in the question;

To determine the value of x, equate the function to 15 and solve for x.

k( x ) = 6x - 12

k( x ) = 15

15 = 6x - 12

Rearrange the equation

6x - 12 = 15

Collect like terms

6x = 15 + 12

6x = 27

Divide but sides by 6

6x/6 = 27/6

x = 27/6

x = 9/2

Therefore, the input value (x) is 9/2, this forms an ordered pair of ( 9/2, 15 ).

The volume of a cylinder is calculated thus:

where π = 3.142

r = radius

h = height

Therefore, the height will be:

V = πr²h

We have to make h the subject of the formula. This will be:

h = V / πr²

The height of a container if the volume is 56.52 cubic inches and the radius is 1.5 inches will be:

The value of p that will guarantee the continuity of the function is given as follows:

p = 6.5.

A function defined by f(x) is continuous at a point x = a if it is defined at x = a, and the lateral limits are equal, that is:

[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]

In the context of this problem, the continuity of the function will be guaranteed if the lateral limits at x = -1 are equal.

To the left of x = -1, the function is less than -1, hence the lateral limit is:

lim x -> -1^- f(x) = lim x -> -1 (-2x² - 8x + 3) = -2(-1)² - 8(-1) + 3 = 9.

To the right of -1, the function is greater than -1, hence the lateram limit is:

lim x -> -1^+ f(x) = lim x -> -1 (4x + 2p) = 4(-1) + 2p = -4 + 2p.

The lateral limits have to be equal for the function to be continuous, hence:

-4 + 2p = 9

2p = 13

p = 13/2

60 cents is 20% of $3.

In essence, percentages are fractions with 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). The value of a number out of 100 is the percentage of that number. The terms "percent" and "cent" combine to make the word "percentage." Having Latin and French roots, the term "cent" means "hundred," while the word "percent" means "per hundred."

Given Data

60 cents as a percent of $3
