The water usage at a car wash is modeled by the equation W(x) = 5x3 + 9x2 − 14x + 9, where W is the amount of water in cubic feet and x is the number of hours the car wash is open. The owners of the car wash want to cut back their water usage during a drought and decide to close the car wash early two days a week. The amount of decrease in water used is modeled by D(x) = x3 + 2x2 + 15, where D is the amount of water in cubic feet and x is time in hours. Write a function, C(x), to model the water used by the car wash on a shorter day. C(x) = 5x3 + 7x2 − 14x − 6 C(x) = 4x3 + 7x2 − 14x + 6 C(x) = 4x3 + 7x2 − 14x − 6 C(x) = 5x3 + 7x2 − 14x + 6
Answers
W(x) - C(x) = 2(W(x) - C(x))
Solving this equation for C(x), we get:
C(x) = (W(x) - 2W(x))
= W(x)(1 - 2)
= (5x3 + 9x2 - 14x + 9)(1 - 2)
= (5x3 + 7x2 - 14x + 6)
Therefore, the function C(x) to model the water used by the car wash on a shorter day is:
C(x) = (5x3 + 7x2 - 14x + 6)

f(n) = 10(1.02)n
Part A: When the scientist concluded his study, the height of the plant was approximately 11.04 cm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(n) represent? (2 points)
Part C: What is the average rate of change of the function f(n) from n = 1 to n = 5, and what does it represent? (4 points)
Answers
Answer:
Step-by-step explanation:
11.04 = 10(1.02)^n
1.104 = 1.02^n
ln 1.104 = ln 1.02^n
ln 1.104 = n ln 1.02
n = ln 1.104/ ln 1.02
n = 4.99630409516
4.99 can be rounded to 5.
So a reasonable domain would be 0 ≤ x < 5
PART B)
f(0) = 10(1.02)^0
f(0) = 10(1)
f(0) = 10
The y-intercept represents the height of the plant when they began the experiment.
f(1) = 10(1.02)^1
f(1) = 10(1.02)
f(1) = 10.2
(1, 10.2)
f(5) = 10(1.02)^5
f(5) = 10(1.1040808)
f(5) = 11.040808
f(1)=10(1.02)^1
f(1)=10.2
Average rate= (fn2-fn1)/(n2-n1)
=11.04-10.2/(5-1)
=0.22
the average rate of change of the function f(n) from n = 1 to n = 5 is 0.22.
A paper company produces 4,950 notebooks in 5 days. How many notebooks can it produce in 13 days?

D.
12,815
Answers
Answer: B)
Hope this helps ;) don't forget to rate this answer !
Step-by-step explanation:
To find the number of notebooks the paper company can produce in 13 days, we need to first find the average number of notebooks it produces per day. We can do this by dividing the total number of notebooks produced in 5 days by the number of days: 4,950 notebooks / 5 days = 990 notebooks/day.
Now that we know the average number of notebooks produced per day, we can multiply this value by the number of days to find the total number of notebooks produced in 13 days: 990 notebooks/day * 13 days = 12,870 notebooks.
Therefore, the answer is B) 12,870 notebooks.

Find the diameter of the circle with a circumference of 80 feet. Use 3.14 for pi. Round your answer to the nearest tenth.
12.7 ft
25.5 ft
40.0 ft
50.9 ft
Answers
Answer:
Option B = 25.5 ft
Step-by-step explanation:
Circumference = 80 ft
C = 2πr
80 = 2 * (22/7) * r
80 = (44/ 7) * r
So, Radius (r) = 80 * (7/44)
= 12.72 Feet
--> Diameter = 2r = 2 * 12.72
= 25.45 Feet
Therefore, Answer = Option B = 25.5 Feet (Round off)
Identify the missing terms in the given arithmetic sequence.
5, ?, ?, ?, -9.
Answers
Answer:
the whole sequence is
5, 1 1/2, -2, -5 1/2, -9
the missing elements were
1 1/2, -2, -5 1/2
Step-by-step explanation:
an arithmetic sequence means that there is always constant added or subtracted from the previous term to create the next term.
we know, we need to go 4 steps or terms to get from 5 to -9.
5 + c = ?
5 + c + c = ??
5 + c + c + c = ???
5 + c + c + c + c = -9
5 + 4c = -9
4c = - 14
c = -14/4 = -7/2
so, we get
? = 5 + -7/2 = 10/2 - 7/2 = 3/2 = 1 1/2
?? = 3/2 - 7/2 = -4/2 = -2
??? = -4/2 - 7/2 = -11/2 = -5 1/2
and the next step is -11/2 - 7/2 = -18/2 = -9
correct.

find exact value in radians
arccos(- square root 3/2)
Answers
= (6π - πi)/6
Step-by-step explanation:
We know that the range of arccosine is [0, π]. Since -√3/2 is less than -1, there is no real number x such that cos(x) = -√3/2. Therefore, the equation arccos(-√3/2) has no solution in the real numbers.
However, if we extend the range of the arccosine function to include complex numbers, we can find a solution using the formula:
arccos(z) = π - i ln(z + i√(1-z²))
where ln denotes the natural logarithm.
Substituting z = -√3/2, we get:
arccos(-√3/2) = π - i ln(-√3/2 + i√(1-(-√3/2)²))
Simplifying the expression under the natural logarithm, we get:
arccos(-√3/2) = π - i ln(-√3/2 + i/2)
To evaluate the natural logarithm, we can write -√3/2 + i/2 in polar form:
-√3/2 + i/2 = e^(i(π/6))
Therefore, we have:
arccos(-√3/2) = π - i ln(e^(i(π/6)))
Using the property ln(e^z) = z of the natural logarithm, we can simplify further:
arccos(-√3/2) = π - i (π/6)
Simplifying the expression, we get:
arccos(-√3/2) = (6π - πi)/6
Therefore, the exact value of arccos(-√3/2) in radians is (6π - πi)/6.

You work in a research laboratory. Each week, you earn $15.75 per hour for the first 40 hours worked and $25.80 per hour for every additional hour worked. Last week, you worked a total of 43 hours, and your boss’s assistant calculated your mean hourly salary using the expression . 15.79 x 40 + 25.80 / 43
What mistake did your boss’s assistant make?
Your boss’s assistant should have divided by 2.
Your boss’s assistant should have divided by 41.
Your boss’s assistant should have multiplied 25.80 by 3.
Your boss’s assistant should have just added 15.75 and 25.80.
Your boss’s assistant should have divided by 40.

10/(x-2)=7/(x+2) what is the solution?
Answers
Answer:
-34/3
Step-by-step explanation:
I've provided the explanation from my e-board in a picture below
We can solve for x by cross-multiplying and simplifying the equation:
10/(x-2) = 7/(x+2)
10(x+2) = 7(x-2)
10x + 20 = 7x - 14
3x = -34
x = -34/3
Therefore, the solution is x = -34/3.
Out of 20 people how many would you expect to say that they like all seasons
Answers
Answer:
None
Step-by-step explanation:
Truly, I'm not sure what type of problem this is, but most people don't favor all the seasons. If there is more to the problem, I would be glad to help further.
Answer:
One possible way to estimate how many people out of 20 would say that they like all seasons is to use a simple random sample. A simple random sample is a subset of a population that is selected in such a way that every member of the population has an equal chance of being included. For example, one could use a random number generator to assign a number from 1 to 20 to each person in the population, and then select the first 20 numbers that appear. The sample would then consist of the people who have those numbers.
Using a simple random sample, one could ask each person in the sample whether they like all seasons or not, and then calculate the proportion of positive responses. This proportion is an estimate of the true proportion of people in the population who like all seasons. However, this estimate is not exact, and it may vary depending on the sample that is selected. To measure the uncertainty of the estimate, one could use a confidence interval. A confidence interval is a range of values that is likely to contain the true proportion with a certain level of confidence. For example, a 95% confidence interval means that if the sampling procedure was repeated many times, 95% of the intervals would contain the true proportion.
One way to construct a confidence interval for a proportion is to use the formula:
p ± z * sqrt(p * (1 - p) / n)
where p is the sample proportion, z is a critical value that depends on the level of confidence, and n is the sample size. For a 95% confidence interval, z is approximately 1.96. For example, if out of 20 people in the sample, 12 said that they like all seasons, then the sample proportion is 0.6, and the confidence interval is:
0.6 ± 1.96 * sqrt(0.6 * (1 - 0.6) / 20)
which simplifies to:
0.6 ± 0.22
or:
(0.38, 0.82)
This means that we are 95% confident that the true proportion of people who like all seasons in the population is between 0.38 and 0.82. Therefore, based on this sample and this confidence interval, we would expect between 8 and 16 people out of 20 to say that they like all seasons in the population.

An artist makes a hanging sculpture out of rhombus-shaped pieces. Each rhombus shape has diagonals of 3.5 centimeters and 5 centimeters. What is the area of each rhombus? 4.25 cm2 8.5 cm2 8.75 cm2 17.5 cm2
Answers
The area of each rhombus is 8.75 \(cm^2\). The correct option is 8.75 \(cm^2.\)
To find the area of each rhombus, we can use the formula for the area of a rhombus:
Area = (diagonal1 × diagonal2) / 2
Given that the diagonals of the rhombus-shaped pieces are 3.5 centimeters and 5 centimeters, we can substitute these values into the formula:
Area = (3.5 cm × 5 cm) / 2
Area = 17.5 \(cm^2\) / 2
Area = 8.75 \(cm^2\)
Therefore, the area of each rhombus is 8.75 \(cm^2\). The correct option is 8.75 \(cm^2.\)
