Step-by-step explanation:
You want examples of use of the rules of logarithms:
[tex]\begin{array}{ll}\vphantom{\dfrac{M}{gN}}1.&\log_b{(MN)}=\log_b{(M)}+\log_b{(N)}\\2.&\log_b{\left(\dfrac{M}{N}\right)}=\log_b{(M)}-\log_b{(N)}\\\vphantom{\dfrac{b}{g}}3.&\log_b{(M^a)}=a\cdot\log_b{(M)}\end{array}[/tex]
The point of these is that M and N and 'a' and 'b' can be anything. (Generally, 'b' will be a positive number greater than 1.) For the purpose here, we can let M ∈ {x^3y, (1+r)}, N ∈ {(x-4), r/n}, a ∈ {4, -3}, b ∈ {2, e}.
Using these values in various combinations, your examples could be ...
1. Product rule[tex]\log_2{((x^3y)(x-4))}=\log_2{(x^3y)}+\log_2{(x-4)}\\\\\ln{((1+r)(r/n))}=\ln{(1+r)}+\ln{(r/n)}\\\\ \log_2{((x^3y)(r/n))}=\log_2{(x^3y)}+\log_2{(r/n)}[/tex]
2. Quotient rule[tex]\log_2{\left(\dfrac{x^3y}{x-4}\right)}=\log_2{(x^3y)}-\log_2{(x-4)}\\\\\\\ln{\left(\dfrac{1+r}{r/n}\right)}=\ln{(1+r)}-(\ln{(r)}-\ln{(n)})\\\\\\ \log_2{\left(\dfrac{x^3y}{r/n}\right)}=\log_2{(x^3y)}-(\log_2{(r)}-\log_2{(n)})}[/tex]
3. Power rule[tex]\ln{(x^3y)^4}=4\ln(x^3y)=4(3\ln{(x)}+\ln{(y)}=12\ln{(x)}+4\ln{(y)}\\\\\log_2{(1+r)^{-3}}=-3\log_2{(1+r)}\\\\\log_2{(x^3y)^{-3}}=-3\log_2{(x^3y)}=-9\log_2{(x)}-3\log_2{(y)}[/tex]

A boat take 4 hour to travel uptream 30 mile. On the return trip downtream it took 2 hour. What i the peed of the boat if it were in till water? What i the peed of the current?
Answers
The speed of the boat if it were in still water is 11.25 miles per hour and the speed of the current is 3.75 miles per hour.
According to the question,
We have the following information:
A boat take 4 hour to travel upstream 30 miles. On the return trip downstream it took 2 hours.
Now, let's take the speed of the boat in still water to be s miles per hour and the speed of the current to be c miles per hour.
Upstream speed = speed in still water - speed of current
Downstream speed = speed in still water + speed of current
Upstream:
s-c = 30/4
s-c = 7.5
s = 7.5+c ...(1)
Downstream:
s+c = 30/2
s+c = 15
Putting the value of s from equation 1:
7.5+c+c = 15
7.5+2c = 15
2c = 15-7.5
2c = 7.5
c = 7.5/2
c = 3.75 miles per hour
Putting this value in equation 1:
s = 7.5+c
s = 7.5+3.75
s = 11.25 miles per hour
Hence, the speed of the boat if it were in still water is 11.25 miles per hour and the speed of the current is 3.75 miles per hour.

Determine which integer makes the inequality 6(n − 5) < 3(n + 4) true. NEED ANSWER ASAP!!!
S:{11}
S:{14}
S:{30}
S:{42}
Answers
Answer:
The answer is n < 14.
Step-by-step explanation:
First, we need to distribute 6, then 3 through the parentheses.
6n - 30 < 3(n + 4)
6n - 30 < 3n + 12
We now need to move the variable to the left-hand side and change its sign.
6n - 30 - 3n < 12
Next, we have to move the constant to the right-hand side and change its sign.
6n - 3n < 12 + 30
Now we need to collect like terms.
3n < 12 + 30
Then, we need to add the numbers.
3n < 42
Last but not least, we need to divide both sides of the inequality by 3. This gets us to:
n < 14

Step-by-step explanation:
"What is 60 is 125% of"
Put this sentence into an expression. The wording is awkward in the question. " . . is 60 is 125% of" is not a complete sentence. I believe it is asking what number results in 60 when we take 125% of it. I'll rephrase it as "125% of what number is 60." Please check my logic on this interpretation.
Write this as an expression, using N for the unknown "number:"

Is the line through points P(9, 7) and Q(16, 2) perpendicular to the line through points R(3, 8) and S(11, 0)? Explain.
Answers
Based on the slope formula applied, we can conclude that, the line that passes through P(9, 7) and Q(16, 2) is not perpendicular to the line that passes through R(3, 8) and S(11, 0).
How to Find the Slope of a Line?Using the slope formula, the slope of a line is calculated as:
m = change in y / change in x.
If two lines are such that one is perpendicular to the other, both lines will have slopes that are negative reciprocal to each other and will therefore have a product of -1.
For example, if the slope of a line is -1/2, the negative reciprocal of -1/2 is 2, which will be the slope of the line that it is perpendicular to.
Find the slope of PQ and RS using the slope formula:
Slope of PQ = change in y / change in x = (7 - 2) / (9 - 16) = 5/-7
Slope of PQ = -5/7
Slope of RS = change in y / change in x = (8 - 0) / (3 - 11) = 8/-8
Slope of RS = -1.
-1 is not the negative reciprocal of -5/7, this implies that both lines are not perpendicular.
Therefore, we can state that lines PQ and RS are not perpendicular to each other.

Answers
Answer:
d) 3 km, and the Mariana Trench is deeper
Step-by-step explanation:
The Mariana Trench is, so to speak, -11 km while the Peru-Chile Trench is -8 km (because they are both below sea level).
For determining the difference between the two, you have to understand that they're both negative, and there is a 3 km difference between -11 and -8. Subtracting a negative makes a positive.
(-8) - (-11) = 3
Since the Mariana Trench is more kilometers below sea level, it's deeper.

find the measure of each interior angle and each exterior angle of a regular pentagon.
Answers
The measure of each interior angle of a regular pentagon is 108° and each exterior angle is 72°.
How to calculate the measure of each interior and exterior angle of a regular polygon?To calculate the measure of each interior and exterior of a regular polygon, we have the following formulae:
The measure of each exterior angle of a regular polygon with n sides is given by "360/n".
And the measure of each interior angle of a regular polygon with n sides is given by "180 - 360/n".
Calculation:The number of sides of a regular pentagon is n = 5.
So, the measure of each exterior angle of the regular pentagon is
= 360/n
⇒ 360/5 = 72°
Thus, the measure of each interior angle of the regular pentagon is
= 180 - 360/n
⇒ 180 - 72 = 108°
Therefore, the measure of each interior and exterior angle of a regular pentagon are 108° and 72°.

How to use trigonometric ratios?The basic trigonometric ratios for an angle θ are expressed as;
sin θ = opposite/hypotenuse
cos θ = adjacent/hypotenuse
tan θ = opposite/adjacent
Now, looking at the given triangle NEB, we are given that;

Please help graph question
Answers
Answer:
a. (-2,-1)
b. y = -(1/2)x-2
Step-by-step explanation:
We will look for an equation of the form y=mx+c, where m is the slope and b is the y-intercept (the value of y when x = 0).
Put the two given points into a table to make it easier to calculate the slopes for Lines A and B. See the attachment for the table. Slope is the change in y for a change in x, often termed the "Rise/Run." Using Line A as the example, the change in y (the Rise) is obtained by taking the Point 2 value for y (7) and subtracting the Point 1 value for y (3): Rise = (7 - 3) = 4. The Run is obtained by taking the Point 2 value for x (2) and subracting the Point 1 value of x (0). The ratio of Rise/Run is 4/2, so the slope is 2. The same process is used for Line B to obtain a slope of 3 for that line.
The two equations can be written with these slopes:
Line A: y = 2x + c
Line B: y = 3x + c
We need to find a value of c for each equation that will force the line through either of their two given points. c can be determined by entering either of that line's points into the equation(s) above and solving for c:
Line A:
y = 2x + c
3 = 2*(0) + c for point (0,3)
c = 3
The equation for Line A is y = 2x + 3
Line B:
y = 3x + c
2 = 3*(-1) + c for point (-1,2)
c = 5
The equation for Line B is y = 3x + 5
The graph of these lines is attached. They intersect at point (-2,-1).
[As a note, the solution may also be found by using substitution and solving for both x and y:
y = 2x+3
y = 3x+5
The solution exists when both y's and x's are equal:
Assume y is equal:
2x+3 = 3x+5
-x = 2; x = -2
----
Assume x is equal:
Rearrange:
y = 2x+3
2x = y-3
x = (y-3)/2
Use this definition of x in the second line equation:
y = 3x+5
y = 3((y-3)/2)+5
y = (3y - 9)/2 + 5
2y = 3y - 9 + 10
-y = 1
y = -1
The solution is (-2,-1), the same as was found by graphing.]
==================================================
A perpendicular line has a slope that is the negative inverse of the referenced line. For Line A, the perpendicual line would be -(1/2). The equation for this line would take the form y = -(1/2)x + c. We want this perpendicular line to intersect the same point that is the solution to the first problem: (-2,-1). Enter this point to find c:
y = -(1/2)x + c
-1 = -(1/2)*(-2) + c for (-2,-1)
-1 = 1+ c
c = -2
The perpendicular line is y = -(1/2)x - 2

One apple weighs 1/4 IB. And another weighs 3/16IB what's the difference
Answers
Answer:
1/16IB
Step-by-step explanation:
Differnce means to subtract which means we need to subract the two fractions. First find the the lowest of common factor for both fractions. In this case it is 16 because 4 can go into 16 four times as 4x4=16.
Since we know that 4 goes into 16 four times we get the 4 and then multiply it by the numerator (the top number of the fraction) for the fracion 1/4. Now the fraction 1/4 is 4/16. Keep the 3/16 the same as the denominator (bottom number of fraction) is already our common factors between the two fractions.
Work Shown:
Orginal Equation: 1/4-3/16
Get common Denomiantors: Convert 4 to 16. 4 goes into 16 four times, multiply by 4 by numerator. 4X1=4.
Final Step: Since both are now common fractions just subtract the numerators keeping the denominators the same of the fractions.
4/16-3/16= 1/16
Final Answer: 1/16IB

What is transversal?
A transversal is a line in geometry that connects two lines in the same plane at two different places. When determining whether two or more other lines in the Euclidean plane are parallel, transversals are important.
This is a transversal question (look at attached). Because the lines are parallel, g will equal to 180(a straight line is 180 degrees) - a. Then, because g + f + e = 180 (since it is a straight line), substitute the values that we know and solve. (61) + f +(66) = 180. f = 53

The length of the freeway is 600 miles. If 0. 5 inch represents 50 miles, what is the length of the freeway on the map? a. 10 inches c. 12 inches b. 6 inches d. 3 inches.
Answers
When a freeway is 600 miles long, its length on a map will be 6 inches, and 50 miles will be represented by 0.5 inches.
What is proportion?A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4). The relationship between two quantities is constant for all values when they are proportional, which indicates that as one quantity rises, the other rises as well. An illustration would be the ratio of a circle's circumference to its diameter, which is equal to pi.
Here,
Length of freeway=600 miles
if 0.5 inch make 50 miles in map,
600:x=50:0.5
=0.5*600/50
=6 inch
The length of the freeway on the map will be 6 inch when it is 600 miles long and 0.5 inch make 50 miles in map.

5.explain why reaction rates decline with time and use this information to correctly process the data (by choosing the proper data points to do linear regression
Answers
Reaction rates decline with time because the reactants are consumed over time, reducing the number of reactant particles available for reaction.
What are reactants?The components that are involved in a chemical reaction are known as reactants. They are the beginning ingredients that are changed into new compounds, known as products, through a chemical process. The left side of a chemical equation is often used to represent reactants, whereas the right side is used to indicate products. The quantity and kind of reactants and products affect the kind of chemical reaction that takes place. Pure substances, such as elements or compounds, or combinations of substances, can function as reactants with time. In a chemical reaction, reactants are changed into products by chemical bonds being broken and formed, releasing or absorbing energy in the process.
How to solve?
As the number of reactant particles decreases, the rate of reaction also decreases. This phenomenon can be observed in many chemical reactions, including reactions that involve the decay of radioactive elements.To correctly process data on the decline of reaction rates with time, it is important to choose the appropriate data points for linear regression. This typically involves selecting data points at regular intervals, such as every minute or every hour, to accurately represent the decline in reaction rates over time. By choosing the right data points and performing linear regression, it is possible to accurately model the decline in reaction rates and make predictions about future reactions.
