Each logarithm as the quotient of two common logarithms is :
[tex]\frac{log\\ 3x}{log \\4}[/tex]
What is logarithmic equation ?In, mathematics a logarithmic equation is inverse of exponential equation. That means, we can easily convert the logarithmic equation into exponential equation and vice versa. The basic form of the logarithm function can be written as .
[tex]log_ax=N[/tex]
where, a is the base of function or equation
x define expression
Mathematically, if [tex]a^N=x[/tex] is an exponential function then, this can be converted to logarithmic function as [tex]log_ax=N[/tex].
There are many formulas that are given to us for solving several simple and complex problems based on logarithmic functions and logarithmic equations.
Some important formulas of logarithms are :
log a × b = log a + log blog a/b = log a - log blog a^x = x log alog a^a = 1log (√x) = 1/2 log (x)The given expression is,
log₄3 x
as, [tex]log_bm= \frac{log_cm}{log_cb}[/tex]
therefore ,
log₄3 x = [tex]\frac{log \ 3x}{log \ 4}[/tex]
Hence, logarithm as the quotient of two common logarithms is :

Dan's has a current credit card statement of $785. his credit card apr is 24.42%. what would be his finance charge if he does not pay the balance in full?
A loan fee is an amount a consumer pays for a loan. This includes taking out a car loan, credit card, or mortgage. Common loan fees include interest rates, origination fees, service fees, late fees, etc. Gross Loan Fees are typically associated with your credit card and consist of any outstanding balance plus any other fees incurred if you carry overdue amounts to your credit card.
If you know three numbers related to your credit card account: credit card (or loan) balance, APR, and billing cycle length, you can calculate your loan fees.
Current Balanced Owned =$785
APR = 24.42%
Let’s suppose the billing cycle is 30 days, then
Finance charge = $15.76
The new balance you owe = $800.76.

A man travelled a distance of 8km in an hour. How long
will it take him to cover a distance of 12km, travelling at
the same speed?
Answer:1 hour 30 minutes
Step-by-step explanation:8 kilometres are compete in an hour, plus another 4 kilometres (to make 12 total) is half of that, so adds another half an hour
The time it will take the man 1.5 hours to cover a distance of 12 km, travelling at the same speed.
What is the relation of speed and distance?
Speed describes how accelerated something or somebody is moving. If you know the distance traveled and the time it took, we can calculate the average speed of an object.
The speed formula is speed = distance / time.
We are given that;
Distance = 12 km
Speed = 8 km/h
Now,
Plugging these values into the formula for time, you get:
time = 12 / 8
time = 1.5 hours
Therefore, by the given speed the answer will be 1.5 hours.

f(x)= x; translation 2 units right followed by a horizontal stretch by a factor of 2
Answer: f(x) = | x |
Step-by-step explanation:
when transforming and translating a function, you use the form a | x - h | + k
a= vertical shrink/stretch factor
h = horizontal movement ( right or left)
k = vertical movement ( up or down )
So a = 1/2 h = 0 and k =2
g(x) = 1/2 | x-0 | + 2
g(x) = 1/2 | x | + 2 [which means vert shrink of 1/2 and up 2 units ]
Please Help! Determine the range of the following graph:
the range of the function in the graph is:
-4 ≤ y ≤ 2
How to determine the range of a given graph?For a function y = f(x), we define the range as the set of the outputs. This is, the set of the possible values of y.
Now, remember that the values of y are on the vertical axis. So if we want to know the range, we just need to look at the vertical axis and see which ones are the allowed values.
If we look at the graph, we can see that the minimum value of y is:
y = -4
And we can see that the maximum value of y is:
y = 2

What is meant by binomial expansion theorem?The Binomial theorem tells us how to expand expressions of the form (a + b)ⁿ, for example, (x + y)⁷. The larger the power is, the harder it is to expand expressions like this directly.
The total number of terms in the expansion of (x+y)ⁿ are (n+1).
The sum of exponents of x and y is always n.
nC₀, nC₁, nC₂, … .., nCₙ are called binomial coefficients and also represented by C₀, C₁, C₂, ….., Cₙ
The binomial coefficients which are equidistant from the beginning and from the ending are equal.
i.e. nC₀ = nCₙ, nC₁ = nCₙ₋₁ , nC₂ = nCₙ₋₂ ,….. etc.
Let the function be (2x - y)⁴
By using binomial expansion theorem, we get
(2x - 3)⁷ = 128x⁷ − 1344x⁶ + 6048x⁵ − 15120x⁴ + 22680x³ − 20412x² + 10206x − 2187

The sum in scientific notation will give:
7.76*10⁶
How to find the sum in scientific notation?
Here we want to find the sum between the numbers (7.3*10⁶) and (4.6*10⁵).
To sum these numbers, we need to have the same exponent in the "10", then we can rewrite:
7.3*10⁶ = 73*10⁵
Now the sum will be:
73*10⁵ + 4.6*10⁵
Taking a common factor we get:
73*10⁵ + 4.6*10⁵ = (73 + 4.6)*10⁵ = 77.6*10⁵
Now we want to go back to scientific notation, so we need to move the decimal point one time to the left, we will get:
77.6*10⁵ = 7.76*10⁶

How to determine the third term of the expansion?The binomial term is given as
(a - b)^4
The r-th term of the expansion is calculated using
r-th term = C(n, r - 1) * x^(n - r + 1) * y^(r - 1)
So, we have
3rd term = C(4, 3 - 1) * (a)^(4 - 3 + 1) * (-b)^(3-1)
Evaluate the sum and the difference
3rd term = C(4, 2) * (a)^2 * (-b)^2
Evaluate the exponents
3rd term = C(4, 2) * a^2b^2
Evaluate the combination expression
3rd term = 6 * a^2b^2
Evaluate the product

How to use the diagram to find the measure of angle 3?The diagram that completes the question is added as an attachment
The angle is given as
<6 = 75
From the diagram, we have
<3 + <6 = 180 degrees
The above is true by the sum of internal angles between parallel lines
So, we have
<3 + 75 = 180
Subtract 75 from both sides of the equation
So, we have
<3 + 75 - 75 = 180 - 75
Evaluate the like terms
So, we have
