The iterated integral in cylindrical coordinates is given by:
∫∫∫f(ρ, θ, z)dV = ∫∫∫xρcos(θ)ρsin(θ)zdρdθdz
Evaluating the integral yields:

Create a graph of this situation.
Show that the equation (y = mx + b) of this graph equals an= -30 + (n - 1)5
The equation (y = mx + b) of this graph is equal to the equation for this arithmetic sequence aₙ = a₁ + (n - 1)d
How to calculate an arithmetic sequence?Mathematically, the nth term of an arithmetic sequence can be calculated by using this mathematical expression:
aₙ = a₁ + (n - 1)d
Where:
d represents the common difference.a₁ represents the first term of an arithmetic sequence.n represents the total number of terms.For the 10th term, the equation for the arithmetic sequence is given by;
a₁₀ = a₁ + (n - 1)d
15 = a₁ + (10 - 1)d
15 = a₁ + 9d
For the 14th term, the equation for the arithmetic sequence is given by;
a₁₄ = a₁ + (n - 1)d
35 = a₁ + (14 - 1)d
35 = a₁ + 13d
Next, we would determine the common difference as follows;
a + 9d = 15
a + 13d = 35
-4d = -20
Common difference, d = -20/-4
Common difference, d = 5.
For the first term of this arithmetic sequence, we have;
a + 9d = 15
a + 9(5) = 15
a = 15 - 45
First term, a = -30
Finally, we would write an equation for the nth term of an arithmetic sequence as follows;
aₙ = a₁ + (n - 1)d
aₙ = -30 + (n - 1)5

question professor liu gave the same quiz to the students in her morning class and in her afternoon class. the average (arithmetic mean) score for the two classes combined was 84. which class had more students?
From the given average the number of students are more in the afternoon quiz as compare to the morning quiz .
As given in the question,
Combined average score of the two classes = 84.
Average score of students in the morning quiz = 80
Let 'x' be the number of students in the morning quiz
80 = ( Sum of all number of students in the morning quiz) / x
⇒ Sum of all number of students in the morning quiz = 80x __(1)
Average score of students in the afternoon quiz = 86
Let 'y' be the number of students in the afternoon quiz
86 = ( Sum of all number of students in the afternoon quiz) / y
⇒ Sum of all number of students in the afternoon quiz = 86y __(2)
Average score of combined classes = ( 80x + 86y ) / (x + y)
⇒ 84 = ( 80x + 86y ) / (x + y)
⇒ 84x + 84y = 80x + 86y
⇒4x = 2y
⇒ y = 2x
Number of students in the afternoon are double the number of students in the morning.
Therefore, from the given averages afternoon class has more number of students than morning class

4w + 10 + 2w = 130
6w + 10 = 130
6w = 120
w = 20
l = 2(20) + 5
l = 40 + 5
l = 45
130 = 2(45) + 2(20)

A new car is purchased for 22600 dollars. The value of the car depreciates at 11. 5% per year. To the nearest tenth of a year, how long will it be until the value of the car is 5200 dollars?.
When the car is acquired for $22600 and depreciates at an 11.5% rate, it will take 6.7 years for its worth to reach $5200.
What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).
Here,
Cost of car=$22600
Rate of depreciation=11.5%
After n years, value of car=$5200
Annual depreciation expense=22600*11.5%
=$2599
Value of the Car = Purchase cost - (Annual depreciation expenses * n)
5200=22600-(2599*n)
2599n=22600-5200
2599n=17400
n=6.695
n=6.7 years
The number of years until the value of the car is 5200 dollars at depreciation rate of 11.5% when purchased at 22600 dollars will be 6.7 years.

You begin the week with 30 units of orange juice. You purchase 50 units. Your ending inventory for the week is 30 units. How many units did you sell?.
Using simple mathematical operations, we know that we sold a total (D) of 50 units of orange juice.
What are mathematical operations?A mathematical function known as an operation converts zero or more input values into a precisely defined output value.
The quantity of operands affects the operation's arity.
The order of operations refers to the rules that define the sequence in which we should perform the operations necessary to solve an equation.
Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction are collectively referred to as PEMDAS.
So, we begin the week with 30 units of orange juice.
We purchase more than 50 units of orange juice.
Total: 30 + 50 = 80 units
Our ending inventory was 30 units.
Units of orange juice sold: 80 - 30 = 50 units

The standard deviation of the number of days absent is found as 1.1616.
Define the term standard deviation?The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.For the stated question-
Number of Days Absent/Probability
0 - 0.601 - 0.202 - 0.123 - 0.044 - 0.045- 0.00Thus, the mean is found as;
Mean = (0x0.60) + (1x0.20) + (2x0.12) + (3x0.04) + (4x0.04)
Mean = 0.72
Standard deviation σ = (0-0.72)² x 0.60 + (1-0.72)² × 0.20 + (2-0.72)² × 0.12 + (3-0.72)² × 0.04 + (4-0.72)² × 0.04
