c. 0, 5, 10, 15, 20, ...

Answers

Answer 1

Only a and c represent function

How is a sequence defined?

In mathematics, a sequence is a list of items that is in order (or events). It has members and is similar to a set (also called elements, or terms). The number of ordered elements determines the length of the sequence (potentially infinite).

a. The sequence 2, 4, 6, 8, 10, ... represents a function. The domain of the function is the set of natural numbers, and the range is the set of even natural numbers. We can create a mapping by using the rule "multiply by 2" to match each input value of the domain with its corresponding output value in the range. For example, 2 maps to 4, 4 maps to 8, 6 maps to 12, and so on.

b. The sequence 1, 0, 1, 0, 1, ... does not represent a function. The reason is that for any given input value, the output value is not unique. For example, the input value of 1 maps to both 1 and 0, which means that the function is not well-defined.

c. The sequence 0, 5, 10, 15, 20, ... represents a function. The domain of the function is the set of natural numbers, and the range is the set of multiples of 5. We can create a mapping by using the rule "multiply by 5" to match each input value of the domain with its corresponding output value in the range. For example, 0 maps to 0, 1 maps to 5, 2 maps to 10, and so on.

What is commutative property in math?

This law simply states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer. Subtraction and division are NOT commutative.

The commutative property of real numbers states that for any real numbers a and b, a + b = b + a and a * b = b * a. In other words, the order in which two real numbers are added or multiplied does not change the result. This property applies to both addition and multiplication of real numbers.

The population of a certain animal species decreases at a rate of 3.5% per year.
You have counted 80 of the animals in the habitat you are studying. When will the number of animals drop to 15? Round your answer to the nearest year.

Answers

On solving the exponential function A(t) = 80 (0.965)^t, the number of animals will drop to 15 after 47 years.

What is an exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

The number of animals studied for the research = 80

The decrease rate of certain species = 3.5%

The rate of decay in exponential term = (1 - 0.035) = 0.965

The exponential function for the situation is -

A(t) = 80 (0.965)^t

Where, t is the number of time periods in years and A(t) = change in the population of animals.

The number of animals drop to 15.

So, substitute the value of A(t) = 15 in the equation -

A(t) = 80 (0.965)^t

15 =  80 (0.965)^t

15/80 = 0.965^t

0.1875 = 0.965^t

ln(0.1875) = t ln(0.965)

t = ln(0.1875)/ln(0.965)

t = -1.6739/-0.0356

t = 47.01

Therefore, the time period value is obtained as t=41 years.

How do you graph inverse operations?.

Answers

The inverse operations can be graphed by determining the inverse of the function by swapping the x and y variables,

Not all functions have inverses, and in order for a function to have an inverse, it must be a one-to-one function that is, there must not be repeated output for many inputs which indicates that not all functions have inverses. The various steps to graph inverse functions can be noted as -

By switching the x and y variables, first determine the function's inverse, and then solve for y. The inverse function, for instance, will be x = f-1 if the original function is y = f(x) (y).By switching the original function's x and y values, plot the inverse function's points. For instance, if the original function is y = 2x + 1, the inverse function would be x = (y-1)/2, and instead of plotting the point (0,1), you would plot (1,0), (2,-1) and so on (-1,2)Over the line y = x, reflect the original function's graph. You will then be shown the inverse function's graph.Lastly, it is required to correctly identify the axes and the points.

Answers

Her displacement is 9.43 miles, and her office is 5 miles west and 8 miles north from her house

How to find her displacement?

Let's use the notation (x, y) to denote Beth's position, we assume she starts at the point (0, 0).

The x-value defines the motion due east (+), west (-)The y-value defines the motion due north (+), south (+)

First she travels 9 miles west and 9 miles north, so the new position is:

(0 - 9, 0 + 9) = (-9, 9)

Then travels 6 miles west and 6 miles nort

(-9 - 6, 9 + 6) = (-15, 15)

then travel 10 miles east and 7 miles south to their office

(-15 + 10, 15 - 7) = (-5, 8)

For what value of k will the pair of linear equations kx 3y k 3 12x ky k have a unique solution?.

Answers

So, the given system will have a unique solution when k=,1

A system of linear equations in two variables will have a unique solution when the equations are consistent and independent.

In this case, the system of equations is kx + 3y = k and 3x + ky = k.

One way to check for consistency and independence is by using the determinant of the coefficient matrix and comparing it to the determinant of the system. The determinant of the coefficient matrix is (kk) - (3ky) = k^2 - 3ky and the determinant of the system is k^2 - k.

For the system to have a unique solution, the determinant of the coefficient matrix must be non-zero and equal to the determinant of the system.

Therefore, the system will have a unique solution when k^2 - 3ky = k^2 - k.

Which means that k=1.

This system will have a unique solution when k=1, and the pair of linear equations will be 1x + 3y = 1 and 3x + ky = 1.

State the equation of the graphed function.

Answers

The equation of the graphed function is given as follows:

f(x) = x³ + 2x² - 5x - 6.

How to obtain the equation of the function?


The equation of the function is obtained considering the Factor Theorem, as a product of the linear factors of the function.

From the graph, the zeros of the function are:

x = -3.x = -1.x = 2.

Hence the function is:

f(x) = a(x + 3)(x + 1)(x - 2).

In which a is the leading coefficient.

Expanding the product, we have that:

f(x) = a(x² + 4x + 3)(x - 2)

f(x) = a(x³ + 2x² - 5x - 6).

When x = 0, y = -6, hence the leading coefficient a is obtained as follows:

-6a = -6

a = 1.

Hence the function is:

f(x) = x³ + 2x² - 5x - 6.

Possible way in which two consecutive odd numbers are added to sum of 2023 is by evaluation using the formula (2n - 1) + (2n + 1) = 2023, so that we have 1010.5 + 1012.5 = 2023

What are consecutive odd numbers

Consecutive odd numbers are a sequence of numbers that are separated by a difference of 2 and are all odd numbers. For example the first four odd numbers are: 1, 3, 5, and 7. Odd numbers can be generated using the formula 2n -1.

We shall represent the first odd number with (2n - 1) so that the two consecutive odd numbers will be expressed as:

(2n - 1) + (2n + 1) = 2023

2n + 2n = 2023

4n = 2023

n = 2023/4 {divide through by 4}

n = 505.75

Therefore the two consecutive odd numbers added to sum of 2023 are derived as:

How do you solve log base 7 1?.

Answers

The solution to log base 7 of 1 is x=0, which is the value of the power to which 7 must be raised to get the value 1.

The logarithm function is an inverse function of the exponential function, and it is defined as log_b(x) = y means b^y = x. In other words, it represents the power to which the base b must be raised to get the value x.

In this case, we are solving log_7(1), which means we are looking for the power to which 7 must be raised to get the value 1.

Since any number raised to the power of 0 is 1, we can say that 7^0 = 1, which means that log_7(1) = 0.

To solve log base 7 1, you need to find the value of x that satisfies the equation log_7(x) = 1.

Using the definition of logarithm, log_b(x) = y means b^y = x.

So to solve log7(1), we can set 1 = 7^x and get x = log7(1) = 0

So the solution to log base 7 of 1 is x=0.

Second loop starts with i = NUM_VALS - 1.Note: These activities may test code with different test values. This activity will perform two tests, the first with a 4-element vector (vector courseGrades(4)), the second with a 2-element vector (vector courseGrades(2)). See How to Use zyBooks.Also note: If the submitted code tries to access an invalid vector element, such as courseGrades.at(9) for a 4-element vector, the test may generate strange results.
