Which are examples of non-visible light?
A) radio waves and ultraviolet light
B) rainbows and X-rays
C) white light from a lightbulb and rainbows
D) white light from the sun and microwaves
The answer to your question which are examples of non-visible light is A:radio waves and ultraviolet light
All the options given from option A to D are all electromagnetic waves since light is an electromagnetic wave.
Option A consists of radio waves and ultraviolet waves which are both non-visible light.Option B consists of rainbows and X-rays. Although, X-rays are non-visible light, rainbows are visible. So, option B is not correct.Option C consists of white light from a light bulb and rainbows. Both white light from a light bulb and rainbows are both visible light. So, option C is not correct.Option D consists of white light from the sun and microwaves. Although, microwaves are non-visible light, white light from the sun is visible. So, option C is not correct.Since both options in option A are both non-visible light,

If a polynomial has a root of −2, what FACTOR will divide evenly into the polynomial?
Given:
A polynomial has a root of −2.
To find:
The factor that will divide evenly into the polynomial.
Solution:
We know that, if c is a root of a polynomial P(x), then (x-c) is a factor of polynomial P(x).
we have,
-2 is a root of polynomial.
⇒ (x-(-2)) is a factor of polynomial.
⇒ (x+2) is a factor of polynomial.
⇒ (x+2) will divide the polynomial completely.
Therefore, the factor (x+2) will divide evenly into the polynomial.
The factors of a polynomial divide the polynomial evenly, without remainder
The factor of the polynomial is x + 2
The root of the polynomial is given as:
[tex]\mathbf{Root = -2}[/tex]
Assume the polynomial is a function of x.
i.e. the variable of the polynomial is x
Then the root can be represented as:
[tex]\mathbf{x= -2}[/tex]
Add 2 to both sides
[tex]\mathbf{x + 2= -2 +2}[/tex]
So, we have:
[tex]\mathbf{x + 2= 0}[/tex]
Hence, the factor of the polynomial is x + 2

-366
After doing some mathematical operations, the resultant answer is -366.
What are mathematical operations?An operation is a mathematical function that transforms zero or more discrete input values into discrete output values. The complexity of the operation depends on how many operands there are. The rules that specify the order in which specific operations should be carried out in order to solve an expression are referred to as the order of operations. Parentheses, exponents, multiplication, division (from left to right), addition, and subtraction are the order of operations. (Left to Right) PEMDAS (from left to right).So, −112−(+312)−(−58):

Answer:
3.125 pounds of beef
Step-by-step explanation:
Set up a proportion where x is the number of pounds of beef needed to feed 10 people:
[tex]\frac{1.25}{4}[/tex] = [tex]\frac{x}{10}[/tex]
Cross multiply and solve for x:
12.5 = 4x
3.125 = x
