Dilation

Step-by-step explanation:

A dilation is a transformation that will shrink or expand a figure, so the area will change.

Answer: b + 24 = 68

Step-by-step explanation:

we are told the zoo has 68 different species of birds so the equation will be = 28. The answers showing = 24 are already wrong.

transported means they are taken away, so we have to subtract 24 (animals that stayed in the zoo) to find b which are the remaining species moved to the barn.

b + 24 = 68
  -  24    -24

b = 44 (transported to the barn)
     24 ( stayed in the zoo)
    68 ( total number of species of birds)

The correct expression to show the species of transported birds will be;

⇒ b + 24 = 68

Where, b is the number of transported birds.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Total number of birds in Roaring Zoo = 68

Number of stayed birds in Zoo = 24

Let number of transported birds = b

Then, We can formulate;

Total number of birds = Stayed birds + Transported birds

Substitute all the values, we get;

⇒ 68 = 24 + b

Therefore,

The correct expression to show the species of transported birds will be;

⇒ b + 24 = 68

Where, b is the number of transported birds.

Using integer numbers, it is found that the expressions that will also be integers are given as follows:

1.75kx, in which k is an integer.

Integer numbers are numbers that have a decimal part of zero, that is, they are whole numbers, either positive or negative.

In the context of this problem, the relevant property is that the multiplication of two integer numbers will always result in an integer number.

We have that the term 1.75x represents an integer number, hence any integer number multiplying 1.75x will result in an integer number.

Symbolically, any integer number can be represented by the variable k,  hence the expressions that will also be integers are given as follows:

Based on the straight line being parallel to the line, L1, and the gradient, the equation of the straight line L2 is y = 2x - 5

The equation of a straight line takes the form:

y = mx + b

Where:

m = slope

b = y - intercept

The slope is the same as the gradient and parallel lines have the same gradient. The gradient of L2 is therefore 2 as well.

Use this gradient and the point (0, -5) to find the y - intercept:

-5 = 2(0) + y - intercept

y - intercept = -5

The equation of the line is:

y = 2x - 5

The image of the function after the translation is g(x) = 6x - 4

Translation involves shifting a function across the coordinate plane

The given parameters are:

f(x) = 6x + 2

The transformation is given as

Translation 6 units down

Mathematically, this transformation can be represented as

(x, y) = (x, y - 6)

When represented as a function, we have

g(x) = f(x) - 6

the question presented here related to compound interest and we can solve that using the formula

let's proceed to substitute the values into the equation

the compounded interest compounded monthly at 6% for 5 years is 3375

The amount is  3250

The accumulated amount is calculated using the initial investment and  interest earned in the given duration

The formula for simple interest is  P×R×T and further, it is divided  by 100

SI= 2500 ×  6 × 5 =75000 ÷100 = 750

Now, for calculating the accumulated amount we will add the initial investment and the interest gained

ie, 2500+750 =3250

Here we are using the simple interest method to calculate the interest as it is assumed to be taken as simple interest when nothing is specified.

Writing 1 trillion in scientific notation is 1 × 10^12.

A scientific notation simply means the way of expressing numbers that are either too large of too small. Scientific notation is a method of expressing numbers that are either too large or too little to be represented in decimal form. In the United Kingdom, it is known as scientific form, standard index form, or standard form.

Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Furthermore, the numbers in the millions place after the decimal required to be represented in a simpler format. As a result, representing a few integers in their expanded form is challenging. As a result, we employ scientific notation.

In this case, I trillion is written as 1,000,000,000,000.

Therefore, it has 12 zeros.

The relation is the relationship between two or more sets of values. Suppose, x and y are two sets of ordered pairs. If set x has a relation with set y, then the values of set x are called domain whereas the values of set y are called range. A relation from a set A to a set B is a subset of A×B. Hence, a relation R consists of ordered pairs (a,b), where a∈A and b∈B. If (a,b)∈R, we say that is related to, and we also write aRb. A connection between the elements of two or more sets is a relation. The sets must be non-empty. A subset of the Cartesian product also forms a relation R. A relation may be represented either by the Roster method or by the Set-builder method.

The quadratic function of best fit for the data is given as follows:

h(t) = -0.004t² +1.032t + 5.667.

Using this function, the initial height of the shot is of 5.67 feet.

The input and the output of the data are given as follows:

As the input increases, the output increases and then it decreases. Since this behavior of increase/decrease is not uniform over the entire domain of the relation, a quadratic function best models this data.

To find the quadratic function of best fit, we insert the points (input,output) into a calculator, from point (20, 25) to point (200,64).

Inserting the points into the calculator, the function is defined as follows:

h(t) = -0.004t² +1.032t + 5.667

The height in which the shot started its flight is given by the height when t = 0, hence:

h(0) = -0.004(0)² + 1.032(0) + 5.667 = 5.667 feet = 5.67 feet (rounded to the hundredths place).
