If the expression is log₃(2 x)², then the expansion of this looks like
2 (log 2+log x)/log 3.
Given that the expression is log₃(2 x)².
We are required to expand the expression by using the properties of logarithmic function.
The change of base formula is basically the formula that will give you the answer of a log with a different base by using only log calculations with a base of 10.
The expression is log₃(2 x)².
log₃(2 x)²=2 [tex]log_{3}[/tex] 2x
=2 (log 2+log x)/log 3
Hence if the expression is log₃(2 x)², then the expansion of this looks like 2 (log 2+log x)/log 3.

Tickets to a sporting event cost $125 each. What's a reasonable domain and range.
The domain and the range of a function is the set of input and output values of the function.
The domain is the set of all whole numbers.
The range is the set of all whole numbers.
Let the number of tickets be x, and the revenue be y.
So, the revenue function will be:
y = 125
The number of tickets cannot be less than 0.
So, the domain of the revenue function is
domain=0,∞
The above means that, the domain is the set of all whole numbers
Similarly, the revenue cannot be less than 0.
So, the range of the revenue function is
range = 0,∞
The above means that, the range is also the set of all whole numbers (in multiples of 125).

Which expression is NOT equivalent to ⁶√16 ²?
(A) (16 r²)¹/₆ (B) 4 r¹/₃ (C) (4 r)¹/₃ (D) ∛4 r}
The correct option is (B) [tex]4 r^\frac{1}{3}[/tex]
The exponential expression [tex]4 r^\frac{1}{3}[/tex] is not equivalent to ⁶√16r².
What is exponential expression ?In, mathematics a exponential function or exponential expression is inverse of logarithmic function. That means, we can easily convert the logarithmic function into exponential function and vice versa. The basic form of the exponential function can be written as [tex]a^x[/tex] .Or we can say that there is always has something power something rule in case of exponents.
where, a is the base expression of function
x = exponent of expression
According to question,
the expression,[tex]\sqrt[6]{16r^2}[/tex] can be written in following ways:
Case 1 : if we simplify the expression using fractional method ,
then, [tex]\sqrt[6]{16r^2}[/tex] = [tex]({16r^2})^{\frac{1}{6}} = (4r)^\frac{2}{6 } = (4r)^\frac{1}{3 }[/tex]
i.e. option (A) and (C) are satisfying the expression
Case 2 : if we simplify the equation exponentially ,
then, [tex]\sqrt[6]{16r^2} = 3\sqrt{4r}[/tex]
i.e. option (D) is satisfying the expression

What are the solution(s) of 2(x+3)²/₃=8 ?
The solution is 5
Rewriting the expression -
2(x+3)²/₃=8
Divide Left Hand Side and Right Hand Side of the equation -
(2(x+3)²/₃)÷2 = 8÷2
Performing division to find the solution
(x+3)²/₃ = 4
Taking cube on both sides of the equation
((x+3)²/₃)³ = 4³
The exponent on Left Hand Side will be multiplied cancelling 3, as it is common in both numerator and denominator
(x + 3)² = 64
Now, taking square root on both sides of equation
√(x + 3)² = √64
Solving the square root on both sides of equation
x + 3 = 8
Shifting 3 to Right Hand Side of the equation
x = 8 - 3
Performing subtraction
x = 5
Hence, the solution of equation is 5

Which translation takes y=|x| to y=|x+3|-1 ?
(A) 3 units right, 1 unit down (C) 3 units left, 1 unit down
(B) 3 units right, 1 unit up (D) 3 units left, 1 unit up
The translation is given by option (C)3 units left ,1 unit down.
A translation occurs when you a graph is moved either horizontally or vertically. That is to say, each point on the parent graph gets translated in one of four directions: left, right, up, or down. There is usually addition or subtraction involved in translation.
Let us consider the function y=|x+3|-1 which is translated from the parent function of y=|x|.
The following steps are followed for the translation of the function:
There is an horizontal shift to the left of the parent function about 3 units .There is a vertical shift downwards of 1 unit.The translation can be seen in the attached graphical representation of the two functions.
The blue line represents the translated function while the red line represents the parent function.
Therefore the translation required for the function y=|x+3|-1 from y=|x| is 3 units left and one unit down .

C.55,000 ft per second
D.1,188,000 ft per second
The speed with which the airplane is flying in feet per second is 917 ft per second.
The speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Given that it just has a direction and no magnitude, speed is a scalar number.
It is given that,
The speed with which the airplane is flying is = 625 mile per hour
We need to find the speed of the airplane in feet per second
Number of seconds in 1 hour = 60 x 60 = 3600s
Number of feet in 1 mile = 5280 feet
Number of feet in 625 mile = 5280 x 625 = 33,00,000 feet
Speed of airplane in feet per second = [tex]\frac{33,00,000}{3,600}[/tex]

Estimate the mean lifetime of a bulb.
Give your answer rounded to 2 DP
?hours
The mean lifetime of a bulb is 31. 57
What is mean?Mean can be defined as the average of a given set of values or elements.
The formula for the mean of a given set of values is expressed as;
Mean = sum of the occurrence of the values/ number of values
Or
Mean = sum of terms/number of terms
From the information given, the frequency of the lifetime of the bulbs were given as;
34, 31, 94, 40 , 0 , 17, 5
The sum of the terms is given as:
= 34 + 31 + 94 + 40 + 0 + 17 + 5
= 221
The number of terms = 7
Substitute into the formula
Mean = 221/ 7
Mean = 31. 571

(Use a thousands comma where applicable.)
The annual insurance premium that Will C. Lowe will be paying is $ 766.5
What is insurance premium?Insurance premium is annual, quarterly, semi annual or monthly payments that has to be paid accordingly to keep our insurance policy active.
Annual insurance premium can be calculated by multiplying the face value per $1000 of the policy by the rate of the insurance of policy.
Given is that Will C. Lowe is 31 year old male who wants to buy a ordinary whole life insurance policy with a face value of $50,000.
From the table we can see that rate of insurance for a 31 year old male for a ordinary whole life insurance policy is 15.33
Then annual premium = (face value per $1000)*(rate of insurance)
= $ (50,000/1000)*(15.33) = $766.5
Therefore, the annual insurance premium that Will C. Lowe will be paying is $766.5

How to write the function that models the relationship?A relationship between a set of values for one variable and a set of values for other variables is known as a variation.
One of the most fundamental concepts in mathematics is the idea of a function, in part because functions are a useful tool for describing and illuminating patterns.
given that
z=30 when x=3 and y=2
z varies directly with x that means z is directly proportional to x.
z = kx .................(1)
z varies inversely with y means z is inversely proportional to y.
z = k 1/y ................(2)
both equation 1 and 2
z = k x/y
k = zy/x
now, find the value of k using given information.
k = 30(2)/3

The bird settles on the branch at the rate of 2.33 meters per second.
What is the rate of change?The rate of change refers to the traveling speed of the bird when perching on the branch.
The rate of change (which is speed) is the distance (altitude) divided by time.
Data and Calculations:The bird's flying altitude above ground = 10 meters
Time in seconds to settle on a branch = 3 seconds
The altitude above ground after settling on the branch = 3 meters
The change in altitude = 7 meters (10 - 3)
Rate of change = 2.33 meters per second (7/3)
