what measurement is the same lenght as 1 meter

The exponential form of the function 5 = log₂ₓ₊₁(a₊b) is (2x ₊ 1)⁵ = (a₊b).

Given the function is:5 =  log₂ₓ₊₁ (a₊b)

we are asked to determine the exponential form of the above function.

The exponential form is an easier way to represent repeated multiplication involving exponents and bases.

It is easy to quickly convert an exponentially written expression into a logarithm using the following formula.

here we have the form loge b  =a5 =  log₂ₓ₊₁(a₊b)

then, e = 2 , a = 5 and

b = (a₊b)5 =  log₂ₓ₊₁(a₊b)

therefore, exponential form is:

(2x ₊ 1)⁵ = (a₊b).

hence we get the required exponential form as (2x ₊ 1)⁵ = (a₊b).

 The value of the simplified expression is 8√3

 Simplification is a process of reducing terms to expressions, which do not generate changes or values.

 Rationalization is a mathematical operation that allows us to determine or eliminate a root of the denominator of a fraction, so that it can be expressed in linear form, either decimal or integer, by the product of a root.

 As defined above, we must perform a mathematical operation to eliminate the root of the denominator without altering the value.

    Since there are no denominators, we will only decompose the square root into factors for simplicity

After simplifying 2√12 -4√27 the answer will be -8√3.

For simplicity, we should basically convert the square root into its factors.

Now we know that the prime factorization of 12 is, 12 =1×2×2×3.

and for 27 it is 27=3×3×3.

Now 2√12 =2[tex]\sqrt{2^2.3}[/tex]=4√3.

And, 4√27 = 4[tex]\sqrt{3^2.3}[/tex]=12√3.

∴2√12 - 4√27

The function that models the change in the animal population is

According to the question we have been given that

        population decreases = 3.5% per year

         Number of animals counted = 80

The formula to be used is

       [tex]F(x) = x (1 + r)^{t}[/tex]           (1)

where,  F(x) = amount of animals counted after t years

              x = initial amount of animals

               r = decrease or increase rate of animal species.

               t = time

Now according to the question,

           r = -0.035

           x = 80

Putting the required values in equation (1) we get

Step-by-step explanation:

To round to one decimal place you have to round the number to its "tenths". When you are rounding, any number which is 5 or above is rounded to the tenth above or in this situation 6 making it 12.5.

The  swimmer will swim 15.23 cm.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

The formula for the Pythagoras theorem is written as c² = a² + b², where c is the hypotenuse of the right triangle and a and b are its other two legs. As a result, the Pythagoras equation can be used to any triangle that has one angle that is exactly 90 degrees to create a Pythagoras triangle.

Given:

Perpendicular = 14 m

Base = 6 m

Using Pythagoras theorem

H²= P² + B²

H² = 14² + 6²

H² = 196 +36

H² = 232

H= 15.23 cm

Hence, the swimmer will swim 15.23 cm.

Solve a System of Linear Equations by Graphing

In this chapter we will use three methods to solve a system of linear equations. The first method we’ll use is graphing. The graph of a linear equation is a line. Each point on the line is a solution to the equation. For a system of two equations, we will graph two lines. Then we can see all the points that are solutions to each equation. And, by finding what the lines have in common, we’ll find the solution to the system.

Most linear equations in one variable have one solution, but we saw that some equations, called contradictions, have no solutions and for other equations, called identities, all numbers are solutions. Similarly, when we solve a system of two linear equations represented by a graph of two lines in the same plane, there are three possible cases, as shown in Figure  5.1.1 :

This figure shows three x y-coordinate planes. The first plane shows two lines which intersect at one point. Under the graph it says, “The lines intersect. Intersecting lines have one point in common. There is one solution to this system.” The second x y-coordinate plane shows two parallel lines. Under the graph it says, “The lines are parallel. Parallel lines have no points in common. There is no solution to this system.” The third x y-coordinate plane shows one line. Under the graph it says, “Both equations give the same line. Because we have just one line, there are infinitely many solutions.”

Figure  5.1.1

For the first example of solving a system of linear equations in this section and in the next two sections, we will solve the same system of two linear equations. But we’ll use a different method in each section. After seeing the third method, you’ll decide which method was the most convenient way to solve this system.

The steps to use to solve a system of linear equations by graphing are shown below.

TO SOLVE A SYSTEM OF LINEAR EQUATIONS BY GRAPHING.

Graph the first equation.

Graph the second equation on the same rectangular coordinate system.

Determine whether the lines intersect, are parallel, or are the same line.

Identify the solution to the system.

If the lines intersect, identify the point of intersection. Check to make sure it is a solution to both equations. This is the solution to the system.

If the lines are parallel, the system has no solution.

If the lines are the same, the system has an infinite number of solutions.

The function definition is an arithmetic sequence and the value of the function f(6) is -12

The function definition is given as

f(1) = 8

f(n) = f(n + 1) + 4

Rewrite the above function as

f(n + 1) = f(n) - 4

Set n = 1

So, we have

f(1 + 1) = f(1) - 4

This gives

f(2) = f(1) - 4

So, we have

f(2) = 8 - 4

Evaluate

f(2) = 4

Set n = 2

So, we have

f(2 + 1) = f(2) - 4

This gives

f(3) = f(2) - 4

So, we have

f(3) = 4 - 4

Evaluate

f(3) = 0

Set n = 3

So, we have

f(3 + 1) = f(3) - 4

This gives

f(4) = f(3) - 4

So, we have

f(4) = 0 - 4

Evaluate

f(4) = -4

Set n = 4

So, we have

f(4 + 1) = f(4) - 4

This gives

f(5) = f(4) - 4

So, we have

f(5) = -4 - 4

Evaluate

f(5) = -8

Set n = 5

So, we have

f(5 + 1) = f(5) - 4

This gives

f(6) = f(5) - 4

So, we have

f(6) = -8 - 4

Evaluate

f(6) = -12

Hence, the value of the function f(6) is -12

Let's call the entire angle between the 10 and 5 sides to be x

Applying to cosine rule:

[tex]9 {}^{2} = 10 {}^{2} + 5 {}^{2} - 2(10)(5)cos(x) \\ 81 = 100 + 25 - 100cos(x) \\ 100cos(x) = 125 - 81 \\ cos(x) = \frac{44}{100} = 0.44 \\ x = arccos(0.44)\approx63.9[/tex]

We can conclude that the angle inside the small triangle is half of x, which i will denote by y

[tex]y = \frac{x}{2} = \frac{63.9}{2} = 31.95[/tex]

Similarly to find the angle which i will denote by z at the right lower corner of the small or large triangle, apply the cosine law again:

[tex]10{}^{2} = 5 {}^{2} + 9 {}^{2} - 2(9)(5)cos(z) \\ 100 = 25 + 81 - 90cos(z) \\ 90cos(z) = 106 - 100\\ cos(z) = \frac{6}{90} = 0.06666 \\ z = arccos(0.06666)\approx86.2[/tex]

The last angle in our small triangle which i will denote by w, will be 180 minus z and y

[tex]w = 180 - (y + z) \\ w = 180 - (31.95 + 86.2) \\ w = 61.85[/tex]

Let t be our missing side,

applying the law of sines:

[tex] \frac{5}{sin(w)} = \frac{t}{sin(y)} \\ t = \frac{5sin(y)}{sin(w)} = \frac{5sin(31.95)}{sin(86.2)} [/tex]

[tex]t \approx2.652[/tex]

keeping in mind that a line with an undefined slope is always a vertical line, check the picture below.

We have the following ordered pairs of the function

(x, y) = {(2,-5) , (4,31), (11,-11), (-21,3)}

Remove the y values to determine the domain

x = {2, 4, 11, -21}

Remove the x values to determine the range
