Answer:

1) The frequency of the light is approximately 4.283 × 10¹⁴ Hz

2) The color of the light is red

Step-by-step explanation:

1) The given parameter;

The wavelength of the line contained in the Neon spectrum, λ = 700 nm = 0.0000007 m = 7.0 × 10⁻⁷ m

The speed of light, v = 299,792,000 m/s

v = f × λ

The frequency, f of the light = v/λ = 299,792,000/(7.0 × 10⁻⁷) ≈ 4.283 × 10¹⁴ Hz

The frequency of the light ≈ 4.283 × 10¹⁴ Hz

2) Given that light with wavelength between 620 - 750 nm constitute red light, we have that the given light with a wavelength of 700 nm is a red light source.

Answer:

3 + x

Step-by-step explanation:

Sum means to add, so you would just add 3 and x (since they haven't given an actual number and only a variable).

The sum of the number 3 and the variable x will be (x + 3).

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

In the linear expression, the degree of the variable is one.

The sum of 3 and a number x.

Then the expression will be

⇒ 3 + x

The number 3 is a constant number and the term x is a variable.

The expression (x + 3) is a linear expression because the degree of the expression is one.

The number of the variable is one, then the expression is linear expression of one variable.

Thus, the sum of the number 3 and the variable x will be (x + 3).

Step-by-step explanation:

A bar chart is a graph with rectangular bars. The graph usually compares different categories. Although the graphs can be plotted vertically (bars standing up) or horizontally (bars laying flat from left to right), the most usual type of bar graph is vertical.

The horizontal (x) axis represents the categories; The vertical (y) axis represents a value for those categories. In the graph below, the values are percentages.

Answer:

The unit price in this situation is the approximate cost per pound of clementines. So, the x-axis should represent the number of pounds. The y-axis should represent the cost.

Step-by-step explanations:

10x - 2x

8x

10x - 2x in fewer terms is 8x.

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

Given is an expression 10x - 2x.

We have to find the difference of these two expressions.

We can add or subtract only the like terms.

Like terms are terms which consist of same kind of variables.

Here 10x and 2x have same variable x.

So they can be subtracted.

10x - 2x = x(10 - 2) = 8x

Hence the difference of 10x and 2x is 8x.

Answer:

Answer: U = 4x^2 and V=y-1

factored : (4x^2+y-1)(4x^2-y+1

Step-by-step explanation:

The value of U and V are 4x² and (y-1) respectively and the factor of the expression is (4x² + (y-1)) and (4x² + (y+1)) option (C) is correct.

It is defined as the combination of constants and variables with mathematical operators.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We want to factor in the following expression:

16x⁴-(y-1)²

We can factor the expression as (U+V)(U-V) where U and V are either constant integers or single-variable expressions.

1) What are U and V?

2)Factor the expression.​

We have an expression:

= 16x⁴-(y-1)²

or

= (4x²)²-(y-1)²

Using the identity:

a² - b² = (a + b)(a- b)

(4x²)²-(y-1)² = (4x² + (y-1))(4x² + (y+1))

The value of U = 4x²

V = (y-1)

The factor of the expression is:

(4x² + (y-1)) and (4x² + (y+1))

Thus, the value of U and V are 4x² and (y-1) respectively and the factor of the expression is (4x² + (y-1)) and (4x² + (y+1))

Determine the position at which the swimmer got the fish

First, we need to add up the downward movements;
