For two functions, f(x) and g(x), a statement is made that f(x) = g(x) at x = 5. What is definitely true about x = 5?

Answers

Answer 1
Answer:

Answer:

At x= 5 the value of both function are equal.

Step-by-step explanation:

Given that two function f(x) and g(x)

And at  x=5  

f(x)=g(x)

It means when we put x=5 in the function f(x) then we get some value and when we put x= 5 in the function g(x) then we get the same value .

Hence , the value of both function at x=5 are equal and we can say that both function intersect at the point (5,0).For example,

Let we take f(x)=x-5

and g(x)=5-x

Put  x=5 in the function f(x) then we get

f(x)=5-5=0

Now we put x=5 in the function g(x) then we get

g(x)=5-5=0

Hence, we get same value for both function .
Answer 2
Answer: When x = 5 then the function f(x) and g(x) are equal so when you insert 5 into the two functions, you will get the same answers for both of the functions.

(4x2)3 + 33
(4x2)3 + 93
(4x3)3 + 33

Answers

To transform the given expression to sum of cubes, calculate first the cube root of the terms. The cube root of the first term, 64x^6 is 4x^2 and that of the second term, 27 is 3.

Thus, the answer to this item is the second choice, (4x^2)^3 + 3^3

Which of the following shows why the commutative property doesn't work under subtraction

Answers

Answer with explanation:

Commutative property under subtraction:

If a and b are any two real numbers such that,⇒ a-b =b-a, then we say that ,a and b Satisfy Commutative property under Subtraction.

Take any two real numbers

a=5.6

And,b=7

→a-b

=5.6-7

= -1.4

→b-a

=7-5.6

=1.4

So,a-b≠b-a

Therefore  , we can say that, real numbers doesn't satisfy commutative property under subtraction.

Option D: ⇒5-1≠1-5

This statement shows that, commutative property doesn't work under subtraction.
Hello!  To answer your question, you first need to know what the commutative property is and does.  Down to the basics, it lets you switch around numbers and it would allow me to say that 2+5=7 and 5+2=7.  This property also works in multiplication, because if I take 4*2=8, and 2*4 still equals 8.  Now that I've either refreshed or hopefully helped you to understand the property better, why wouldn't it work under subtraction?  If you switch numbers around in subtraction, will your answer still be the same?  Once you answer that, take a peak at the worksheet!  I hope this has helped in some way, and if you have any further questions send me a question or another message.  Good luck :)

There are many cylinders with a height of 9inches. Let r represent the radius in inches and v represent the volume in cubic inches what belongs in cell A

Answers

Complete question :

There are many cylinders with a height of 9 inches. Let r represent the radius in inches and V represent the volume in cubic inches.

a. Complete the table relating the radius and volume of cylinders with height 9 inches. Write each volume as a multiple of , or round to the nearest cubic inch.

Answer:

A = 9π in³

B = 36π in³

C = 81π in³

Step-by-step explanation:

Radius, r = 1, 2, 3

Height of cylinder = 9

Volume, V of cylinder : πr²h

For, r = 1

V = π(1)²9 = 9π in³

For, r = 2

V = π(2)²9 = 4*9π in³ = 36π in³

For r = 3

V = π(3)²9 = 9*9π in³ = 81π in³

Which represents the polynomial written in standard form?

4m – 2m4 – 6m2 + 9

Answers

If you would like to write the polynomial in standard form, you can do this like this:

4m - 2m^4 - 6m^2 + 9

Writing the polynomial in standard form means that you have to write the terms by descending degree:
- 2m^4 - 6m^2 + 4m + 9

The correct result would be - 2m^4 - 6m^2 + 4m + 9.

An equation which represents the polynomial written in standard form is 2m⁴ - 6m² + 4m + 9.

What is a polynomial?

A polynomial can be defined as a mathematicalexpression which is comprises intermediates (variables), constants and exponents with different numerical value, that are typically combined by using mathematical operations such as:

  • Addition
  • Subtraction
  • Multiplication

In this scenario, the polynomial would be written in standard form by rearranging it in descending degree of exponents:

2m⁴ - 6m² + 4m + 9.
