First substitute in the numbers and make sure to use ( ) when plugging in negative values. For example, the first one says n=4, you can substitute n from the expression to 4. So n^2 + 3n + 8 will turn into 4^2 + 3(4) + 8 which is 16 + 12 + 8 = 36. You can do this with the other questions.

What are the solution(s) of 2(x+3)²/₃=8 ?
Answers
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
Answers
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 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?
Answers
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

Answers
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).

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,

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
k = 60/3
k = 20
now,
z = k x/y
z = 20 x/y

Answers
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.

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

A. 426 ft per second
B.917 ft per second
C.55,000 ft per second
D.1,188,000 ft per second
Answers
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]
= 916.66 feet per second
~917 feet per second
Hence, the speed with which the airplane is flying in feet per second is 917 ft per second.
