x → ∞ y → ∞ and as  x →- ∞ y → -∞  is the end behavior of the graph of the polynomial function y = 10x⁹ – 4x

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The meaning of end behavior is how the function ‘y’ (in this case) moves when x tends towards both ∞ and - ∞.

As x → ∞ y → ∞.

This is apparent from the upward movement of the graph of the function y=10x⁹ –4x

As x →- ∞ y → -∞

This inference is also drawn from the above graph i.e. as x values become more negative the graph of y also travels towards infinity i.e. southward on the LHS of the above graph.

Even though the graph of the function remains flat in between x = -4 to x = 4.

After these points, the graph moves towards infinity exponentially.

Hence, x → ∞ y → ∞ and as  x →- ∞ y → -∞  is the end behavior of the graph of the polynomial function y = 10x⁹ – 4x

Find the mean rounded to the nearest tenth median mode and range 59,50,54,50,50

Answers

Answer:

Mean = 52.6

Median = 50

Mode = 50

Range = 9

Step-by-step explanation:

How to find the mean

The mean of a set of numbers is the sum divided by the number of terms.You add 59,50,54,50,50 then divide it by 5 because there are 5 numbers

How to find the median

Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

How to find the mode

The mode is the element that occurs most in the data set. In this case,  50 occurs  3  times.

How to find the range

Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 59 − 50 = 9

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

Let h represents the hourly fee.

Let C be the total charge and t be the rental time in hours.

C = ht + 43

Putting the given values into the equation, we get:

64 = 7h + 43

7h = 21

h = 3

Therefore, the hourly fee is $3.00 per hour.
