The simplified form of the logarithmic expression, 6 log₃x - 7 log₃y + 4 log₃z, is log₃{(x⁶z⁴)/y⁷}. Hence, the third option is the right choice.
What are the laws involved in the simplification of logarithmic expressions?The laws involved in the simplification of logarithmic expressions are:
Power law: [tex]a log_x b= log _xb^a[/tex]Product law: [tex]log_xa + log_xb = log_xab[/tex]Quotient law: [tex]log_xa - log_xb = log_x\frac{a}{b}[/tex]Base changing law: [tex]log_ab = \frac{log_xb}{log_xa}[/tex]How to solve the question?In the question, we are asked to simplify the logarithmic expression,
6 log₃x - 7 log₃y + 4 log₃z.
The simplification of the provided logarithmic expression can be done as follows:-
6 log₃x - 7 log₃y + 4 log₃z,
= log₃x⁶ - log₃y⁷ + log₃z⁴ {Using the Power law: [tex]a log_x b= log _xb^a[/tex]}
= log₃x⁶ + log₃z⁴ - log₃y⁷
= log₃x⁶z⁴ - log₃y⁷ {Using the Product law: [tex]log_xa + log_xb = log_xab[/tex]}
= log₃{(x⁶z⁴)/y⁷} {Using the Quotient law: [tex]log_xa - log_xb = log_x\frac{a}{b}[/tex]}.
Thus, the simplified form of the logarithmic expression, 6 log₃x - 7 log₃y + 4 log₃z, is log₃{(x⁶z⁴)/y⁷}. Hence, the third option is the right choice.

A baby giraffe was born at a wildlife preserve. The giraffe was 6 feet tall when it was born, and it grew 1.75 feet over the next 7 months.
If the giraffe continues to grow at the same rate, at what age will it reach a height of 15 feet?
The age of the giraffe when he is 15 feet tall be 1 year 1 month and 16 days.
What is fraction?
A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Giraffe height = 6 feet
Height grew in 7 months= 1.75 feet
Giraffe's height in 7 month = 7.75 feet
Giraffe's height, 1 feet= [tex]\frac{7}{7.75}[/tex] month
= 0.9032 months
Giraffe's height, 15 feet= 0.9032 x 15 month
= 13.548 month
= 13 months 16 days approx.
= 1 year 1 month 16 days
Hence, the age of giraffe will be 1 year, 1 month and 16 days

Step-by-step explanation:
£20 is divided between June, Sushil &
Fiona so that June gets twice as much as
Sushil, and Sushil gets three times as
much as Fiona. How much does June get?
Answer:
Therefore, June gets £6
Step-by-step explanation:
Total amount = £20
Assume:
June's share = a
Sushil's share = b
Fiona's share = c
a = 2b -----------------------(1)
b = 3c -----------------------(2)
c = b ÷ 3 -------------------(3)
a + b + c = £20 --------(4)
Substitute equations (1) and (3) in equation (4)
2b + b + (b ÷ 3) = £20
10b ÷ 3 = £20
b = £20 * 3 ÷ 10 = £6
a = 2 * £6 = £12
c = £6 ÷ 3 = £3
Therefore, June gets £6

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given the equation 3(2 ^ (2t - 5)) - 4 = 10
Add 4 to both sides:
3(2 ^ (2t - 5)) - 4 + 4 = 10 + 4
3(2 ^ (2t - 5)) = 14
Divide both sides of the equation by 3:
[3(2 ^ (2t - 5))] / 3 = 14/3
2 ^ (2t - 5) = 14/3
Take the log of each side:
(2t - 5)log(2) = log(14/3)
Divide each side by log 2:
2t - 5 = log(14/3) / log(2)
Add 5 to each side of the equation:
2t = log(14/3) / log(2)
Use the Exponential Property and write in decimal form:
t = 1.11
The steps arranged in the correct order is Add 4 to both sides, Divide both sides of the equation by 3, Take the log of each side, Divide each side by log 2, Add 5 to each side of the equation and Use the Exponential Property and write in decimal form.

What is the mode of the data:
Answer:
3
Step-by-step explanation:
Mode is what number occurs the most in data or in this question which number contains the most X's
Answer:
3 is the mode of the data set shown
Step-by-step explanation:
What is shown in the picture is called a data set. What we need to find is the mode. The mode, is the number shown in the data the most. Each x shown represents how many times the number below it shows in the data set. So, all we need to do is find the column with the most x's.
Through doing this, we can see that the column of 3, has the most x's (4 x's). Meaning that 3 is the mode of the data.

The above table represents a linear function;
Start by calculating the slope (m) using:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{14 - 2}{1 - 0}[/tex]
Evaluate
m = 12
The equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
y = 12(x - 0) + 2
Evaluate
y = 12x + 2
Hence, the equation for the number of arrangement from the number of guest is y = 12x + 2

What is the geometric possibility of being in the square and not in the circle? The radius of the circle is five inches. Express percent’s to the nearest tenth.
A. 21.5%
B. 23.0%
C. 20.0%
Answer: A
Step-by-step explanation:
The area of the square is 10^2 = 100.
The area of the circle is (pi)(5^2) = 25pi.
So, the area of the region in the square but not in the circle is 100 - 25pi.
Thus, the desired probability is (100-25pi)/100, which is about 21.5%
