A plane is an undefined term because:

Let us consider the options.

Option 1: can be named using three non collinear point.

This is not the correct answer because  a plane is a flat, two-dimensional surface that extends infinitely far. Therefore, it is undefined because it is a flat surface that extends indefinitely in all directions.

Option 2: is described generally, not using a formal definition.

This is not the correct answer because  a plane is a flat, two-dimensional surface that extends infinitely far. Therefore, it is undefined because it is a flat surface that extends indefinitely in all directions.

Option 3: is where other geometric shapes can be constructed.

This is not the correct answer because  a plane is a flat, two-dimensional surface that extends infinitely far. Therefore, it is undefined because it is a flat surface that extends indefinitely in all directions.

Option 4: is a flat surface that extends indefinitely in all directions.

This is the correct answer as plane is a flat surface that extends indefinitely in all directions.

Therefore, option 4 is the correct answer.

How do you write 20/100 as a decimal
zhannawk [14.2K]
To get a fraction as a decimal, you have to divide the numerator by the denominator (commonly on a calculator, which is the easiest). 

In this case, divide 20 by 100 to get the answer of 0.2.

So, 20/100 as a decimal is 0.2.

The profit function for a product is given by p(x)=-x^3+3x^2+900x-2100, where x is the number of units produced and sold and P i
nalin [4]

Answer:

x = 30 and x = 3 both solve the equation correctly. See work below.

Step-by-step explanation:

The very first step is to realize that p(x) is in hundreds of dollars and that the given number is not. 60000 is not in hundreds of dollars. It is in dollars. 60000 dollars = 60000/100 = 600 hundreds of dollars.

Make the polynomial = 600

-x^3+3x^2+900x-2100 = 600  Subtract 600 from both sides

-x^3+3x^2+900x-2100 - 600 = 0  Combine

-x^3+3x^2+900x- 2700 = 0           Group  the first and second term and the Thrid and fourth terms.

(-x^2 + 3x^2) + (900x - 2700) = 0  Bring out the common factors from both groups.

-x^2(x - 3) + 900(x - 3) = 0 Factor out x - 3 on both sides of the plus sign

(- x^2 + 900)(x - 3) = 0       Reverse -x^2 + 900 to  900 - x^2

(900 - x^2)(x - 3) = 0          factor (900 - x^2) using the difference of squares

(30 - x)(30 + x) (x - 3) = 0

The two answers that work are

30 - x = 0                           Solve

- x = - 30                            Divide by - 1

-x/-1 = -30/-1                       Combine                          

x  = 30

============

x - 3 = 0

x = 3

===========

There are two values that will work to give p(x) = 600. There is no way to account for why both values work.

The graph below confirms both answers.

f(-3) = -35

Step-by-step explanation:

f(4) = 12(4) + 1 = 48 + 1 = 49

f(-3) = 12(-3) + 1 = -36 + 1 = -35

What fraction is equal to 3 1/9 ?
Masteriza [31]

Answer:

28/9

Step-by-step explanation:

We will have to convert the given question into improper fraction before solving

So let's solve the question

3 1/9

Can be written as 28/9 which is improper fraction

Since there's nothing that can be used to divide both the numerator and denominator

Then our final answer is 28/9

But in the case where the fraction can be divided we can actually solve further
