Which shows one way to determine the factors of x3 4x2 5x 20 by grouping?.
The factors of the polynomial are [tex]\rm (x^2+5)(x+4)[/tex]
What are the factors?
Factorization of an algebraic expression means writing the given expression as a product of its factors.
These factors can be numbers, variables, or an algebraic expression.
Given
The given polynomial is;
[tex]\rm x^3 + 4x^2 + 5x + 20[/tex]
The factors of the polynomial are as follows;
[tex]\rm x^3 + 4x^2 + 5x + 20\\\\x^2(x+4)+5(x+4)\\\\(x^2+5)(x+4)[/tex]
Hence, the factors of the polynomial are [tex]\rm (x^2+5)(x+4)[/tex].

Which pair of functions are inverses of each other?
Answer:
B
Step-by-step explanation:
As you can see if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.
The pair of functions that are inverses of each other will be f(x) = 10x - 5. g(x) = x - 5/10. so option B is correct.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output. Inverse means that the function is reversed from the original function, f(x).
A: The original function, f(x) = x/8 + 3. g(x) = 8x - 3. they are not inverse functions.
B: The original function, f(x) = 10x - 5. g(x) = x - 5/10. they are inverse functions.
C: The original function, f(x) = 4/x - 3. g(x) = 1/x + 3/ 4, they are not inverse functions.
Hence, the pair of functions that are inverses of each other will be f(x) = 10x - 5. g(x) = x - 5/10. so option B is correct.

Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail. What is the efficiency of the hammer? 1. 4% 7% 70% 143%.
If Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail then the efficiency of the hammer is 70%
What is efficiency ?Efficiency is the ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.
Given that Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail.
Efficiency of hammer can be calculated as
efficiency = output obtained / input given
E=105/150
E=7/10
E=0.7
Converting into percentage
[tex]E=0.7\times100\%\\\\E=70\%[/tex]
If Anouk does 150 J of work using a hammer to pull a nail out of a piece of wood, and the hammer does 105 J of work on the nail then the efficiency of the hammer is 70%

A TV screen has a diagonal length of 156cm, the angle in the top corner is 37◦. Calculate the height of the TV screen
The TV screen is an illustration of a right triangle
The height of the TV screen is 124.6 cm
How to calculate the heightThe diagonal is given as:
d = 156 cm
The angle at the top is given as:
Angle = 37 degrees
The height is then calculated using the following cosine ratio
[tex]\cos(37) = \frac h{156}[/tex]
Make h the subject
[tex]h = 156 * \cos(37)[/tex]
Evaluate
h = 124.6
Hence, the height of the TV screen is 124.6 cm
