The frequency of the red light is 4.6 × 10⁵ Hz

From the question, we are to determine the frequency of the red light with the given wavelength

From the given information,

Wavelength = 650 nm

c = 3.0 × 10⁸ m/s

From the formula,

c = fλ

∴ f = c/λ

Where c is the speed of light

f is the frequency

λ is the wavelength

Thus,

f = 3.0 × 10⁸/650

f = 4.6 × 10⁵ Hz

Hence, the frequency of the red light is 4.6 × 10⁵ Hz

Answer to this question is:

Domain of given function is (-∞,∞),{x|x∈R}

Range of given function is [0,∞),{y|y≥0}

Inverse of given function is √2x,-√2x

The domain is all values of x that make the expression defined.The entire range of independent variable values is the domain of a function.

This definition can be stated simply as follows: The domain is the collection of all x-values that can be used to make the function "work" and produce actual y-values.

When choosing the domain, keep in mind that a fraction's denominator (bottom) cannot be 0.

Interval Notation:(-∞,∞)

Set-Builder Notation:{x|x∈R}

The set of all valid y values constitutes the range.Graph may be used to find the values.

Answer:

log₇(xy/z)

Step-by-step explanation:

We know that

[tex]\log_ax = b \implies a^b = x[/tex]

we also know that:

[tex]a^b \cdot a^c = a^{b + c}[/tex]

so it follows that

[tex]\log_ax + log_ay = log_a(xy)[/tex]

from:

[tex]\frac{a^b}{a^c} = a^{b - c}[/tex]

follows that

[tex]\log_ax - log_ay = log_a(\frac{x}{y})[/tex]

so

[tex]\log_7x + \log_7y - \log_7z = \log_7(xy) - \log_7z = \log_7(\frac{xy}{z})[/tex]

From unitary method calculations, we have found that the large jar is the best value for money because a penny buys more honey.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We need to determine which has the best value for money using the quantity a pound can purchase.  

So, first for the large jar.

£4.10 will be purchase 540g of honey then,

£1.00 will be purchase xg

Then cross multiplying for x will be;

x = 1.00 (540g )/4.10

x = 131.7g

Hence for the large jar a penny will buy 131.7g of honey.

Now second for the small jar

£2.81 will be purchase 360g of honey then,

£1.00 will purchase xg

Now cross multiplying

x = 1.00 (360g )/ 2.81

x = 128.1g  

Hence for the small jar a penny will buy 128.1g of honey.

The area of the rectangle with a base of 5ft and a height of 2 inches is: 120 square inches.

The area of a rectangle is the product of the length of its base and its height.

Area of rectangle = (base)(height)

Given the parameters:

Length of the base of the rectangle = 5 ft

[Note: 1 ft = 12 inches]

Convert 5 feet to inches

5 feet = (5)(12) = 60 inches

Height of the rectangle = 2 inches

Substitute

Area of the rectangle = (60)(2)

Area of the rectangle = 120 square inches

In conclusion, the area of the rectangle with a base of 5ft and a height of 2 inches is: 120 square inches.

The proportionality constant for the above equation y = 2.35x is 2.35.

An equation can be defined in several ways. Algebraically speaking, an equation is a statement that shows the equivalence of two mathematical expressions.

A linear equation could have more than one variable. If a variable's maximum power constantly equals one, an equation is considered to be linear.

Let us x ∝ y.

Following that, x = ky, where k is a constant or proportional.

When two variables that were in proportion are split, it will result in a constant proportional because k = x/y.

The constant of proportionality for the above equation y = 2.35x will be y/x = 2.35.
