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

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
In 2 decimal place
Mean = 31. 57
Thus, the mean lifetime of a bulb is 31. 57

c rounded to the nearest 10 is 640.
d rounded to the nearest 10 is 420.
what are the lower and upper bounds of c + d?
The bounds of C is 635 - 644
The bounds of D is 415 - 424
The lower bounds of C + D can be found by adding 635 + 415, which is 1050
The upper bounds of C + D can be found by adding 644 + 424, which is 1068
So, the lower bounds of C + D is 1050 and the upper bounds is 1068
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
The upper bound is 1068 and the lower bound is 1050
What is the upper bound and lower bound of a number?The lower bound is the smallest value that would round up to the estimated value. The upper bound is the smallest value that would round up to the next estimated value.
Given here, c rounded to the nearest 10 is 640 and d rounded to the nearest 10 is 420. Then we have the minimum and maximum value as
Min C = 635 and Max C = 644 & Min D=415 and Max D = 424
Therefore the upper bound for c+d = 644+424
= 1068
And the lower bound for c+d = 635+415
=1050
Hence The upper bound is 1068 and the lower bound is 1050

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 .

Use the Change of Base Formula. What is the value of each expression?
b. log₄18
The value of the given expression that is log₄ 18 = 2.084
A logarithm operation can be rewritten as a fraction of logarithms with a new base using the change of base formula.
Example: logₐ b = (logₓ b) / logₓ a)
Therefore, log₄ 18 = (log₁₀ 18) / (log₁₀ 4).....eq(i)
We know, log₁₀ 4 = 0.602
We can write log₁₀ 18 as log₁₀(2x9).
Using the product rule of logarithms, log₁₀ 18 = log₁₀2 + log₁₀9log₁₀ 18 = 0.301 + 0.954log₁₀ 18 = 1.255
Substituting the value of log₁₀ 18 = 1.255 in eq(i) we get,
log₄ 18 = 1.255/0.602log₄ 18 = 2.084
The final answer to the question is log₄18 = 2.084 using the change of base formula.

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
