There probability two ways to pick two representatives with one majoring in mathematics and the other majoring in computer science.

In order to pick two representatives with one majoring in mathematics and the other majoring in computer science, there are two approaches that can be taken. The first approach is to pick one representative who majors in mathematics first, then the second representative who majors in computer science. The second approach is to pick one representative who majors in computer science first, then the second representative who majors in mathematics. Both of these approaches would yield two representatives, one with a mathematics major and the other with a computer science major. It is important to note that whichever approach is taken, both representatives must be chosen from the same pool of potential representatives. Thus, the pool of potential representatives should be large enough to encompass both mathematics and computer science majors in order to successfully pick two representatives with one majoring in mathematics and the other majoring in computer science.

The image is the final appearance of a figure after a transformation operation. The pre-image is the original appearance of a figure in a transformation operation.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's final shape and location.

Preimages are the original, unaltered shapes, and images are the new (transformed) shapes. To put it another way, a transformation is a process that maps a preimage onto an image.

Answer:

If each shopping trolley is 1 meter long, and each trolley in the stack adds 0.25 meters, then the total length of the stack will be equal to the length of each trolley plus the length added by each additional trolley in the stack. This means that the total length of the stack will be equal to 1 + 0.25 = 1.25 meters per trolley.

If the stack has a total length of 10 meters, and each trolley adds 1.25 meters to the stack, we can divide the total length by the length added by each trolley to find the number of trolleys that can be stacked in a single line of 10 meters:

10 / 1.25 = <<10/1.25=8>>8 trolleys

Therefore, if each shopping trolley is 1 meter long and each trolley in the stack adds 0.25 meters, a single line of 10 meters could hold a stack of 8 trolleys.

A function is a mathematical relationship between the domain and the range, two sets of values. The range is the set of output values that the function produces, and the domain is the set of input values for which it is defined.

What is a function, exactly?

a mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

Consider the function f(x) = x^2 as an illustration. This function generates the value f from the supplied value x. (x). This function will return the value 9 if the given value is 3, since 3^2 = 9.

Generally speaking, a function describes the relationship between two sets of values (the domain) (the range). For instance, the relationship between the input value x and the output value f(x) is described by the function f(x) = x^2.

A formula, which is a guide that explains how to calculate the output value for a specific input value, is typically used to express a function. For instance, the function f(x) = x^2 has the formula f(x) = x^2. We just enter the input value into the formula and simplify to determine the output value for a particular input value.

A fundamental idea in mathematics, functions are used to model and describe a wide variety of real-world occurrences. For instance, the quadratic function f(x) = x^2 + 2x + 1 can be used to simulate how an item would move in the presence of gravity. A population's expansion over time can be predicted using the exponential function f(x) = 3^x.

Step-by-step explanation:

To find the number of kilowatt hours of electricity the Abubakar family will be using 12 months after they've started decreasing their usage, we can substitute 12 for x in the equation y = –25x + 850. This gives us y = –25 * 12 + 850 = –300 + 850 = 550.

Therefore, the Abubakar family will be using 550 kilowatt hours of electricity 12 months after they've started decreasing their usage.

The standard form of the complex number is respectively 2√3 i - 15 + √300 i,4 - 7 i, and -14 + 9 i.

Complex numbers are helpful in finding the square root of negative numbers.

A complex number is the sum of a real number and an imaginary number.

(a)

As per the given, 2√-3 - 15 + √-300

Since, √-1 = i thus,

2√3 i - 15 + √300 i

(b)

As per the given, (15 - 10i)/(2 + i)

By rationalization,

(15 - 10i)/(2 + i) x (2 - i)/(2 - i)

The one-time administration fee is (d) $60

From the question, we have the following parameters that can be used in our computation:

12 months costs $660.

15 months costs $810.

This means that

(x, y) = (12, 660) and (15, 810)

For the one-time administration fee, we have

(x, y) = (0, y)

So, we calculate the slope using

slope = (y₂ - y₁)/(x₂ - x₁)

So, we have

(y - 660)/(0 - 12) = (810 - 660)/(15 - 12)

This gives

(660 - y)/12 = 50

Replacing the values of h and k to create the equation of the transformed function gives us; y = [∛(x - 4)] - k

The graph represents a transformation of the parent cube root function.

The parent cube root function is; y = ∛x

In this parent function, we see that the value of h  and k are equal to 0. Where;

h = 0, k = 0 in parent function

Then the graph changes direction at the coordinate (0,0) in parent function.

From the given graph, we can see that it changes direction at the coordinate (4,-1)

This tells us that the graph is shifted by 4 units to the right and then by 1 unit downwards.

Thus, it means that the value of h = 4  and the value of k = 1.

C. Since the maximum value in the table for bacteria A is greater than the maximum value in the table for bacteria B, bacteria A has a faster growth rate than bacteria B.

False, because the maximum value of each table is given in different times, and also the initial value of each table is different.

The vertex form of line f(x) = ax² + bx + c  is y = a(x - h)² + k where the vertex is (h, k).

The vertex form of a line is one of the representations of the line in an equation format. Here the line focused on the coordinates of the vertex.

For a line, f(x) = ax² + bx + c, the vertex form is y = a(x - h)² + k; vertex at (h, k).

To convert the general form to the vertex form, the general equation is simplified as below:

y = ax² + bx + c

  = ax² + bx + c + b²/4a - b²/4a

  = a(x² + b²/4a² + b/a) + (c - b²/4a)

  = a(x² + (b/2a)² + 2b/2a) + (c - b²/4a)

  = a(x + b/2a)² + (c - b²/4a)

⇒ y = a(x - (-b/2a))² + (c - b²/4a)

Consider -b/2a = h and (c - b²/4a) = k, then we get

y = a(x -h)² + k; vertex form of the given line.

⭐Multiplication rules

⭐ Exponent multiplication rule

⭐ Multiplying two terms with variables

We need to utilize these 3 key points (⭐) when multiplying to terms with variables.

First, let's multiply the coefficients:

-8 * -2 = 16

Next, let's multiply the variables:

[tex]x^7 * xy^3[/tex]

These two variables have the same base (x), so we will add their exponents up.
