The new price for the car when there's an increase of 6% is $35616.
How to calculate the new price?Given that the dealership increased the price of a certain car by 6% and the original price was $33,600.
The new price will be:
= Original price + Increase in price
= $33600 + (6% × $33600)
= $33600 + $2016
= $35616
The new price is $35616.

Which inequality is equivalent to the given inequality? -4(x+7)< 3(x-2)
Answers
An equivalent inequality to the given \(-4(x + 7) < 3(x - 2)\) is \(7x > -22.\)
To find an equivalent inequality, we can start by simplifying the given inequality and then make adjustments to preserve its truth.
Let's simplify the given inequality step by step:
\(-4(x + 7) < 3(x - 2)\)
Expanding both sides:
\(-4x - 28 < 3x - 6\)
Grouping like terms:
\(-4x - 3x < -6 + 28\)
Simplifying:
\(-7x < 22\)
To maintain the direction of the inequality, we need to multiply both sides by -1.
However, when we multiply or divide both sides of an inequality by a negative number, the direction of the inequality is reversed.
Therefore, we need to flip the inequality sign:
\(7x > -22\)
Hence, an equivalent inequality to the given \(-4(x + 7) < 3(x - 2)\) is
\(7x > -22.\)

6. A hospital needs a supply of an expensive medicine. Company A has the most
supply available, 1.3 milligrams, which is twice the difference between the weight of
Company B's supply and Company C's, and 0.9 milligram more than Company C's
supply. How many milligrams can the hospital get from these three companies?
Answers
Answer:
The hospital gets \(2.75\:\rm{mg}\) of medicines from these three companies.
Step-by-step explanation:
Company A has \(1.3\) milligrams, which is \(0.9\) milligram more than Company C's.
If \(A,B,C\), are the medicines produced by Companies A,B,C, respectively,
then, \(A=1.3\:\rm{mg}\), and its expression is given as,
\(\begin{aligned}A&=0.9+C\\1.3&=0.9+C\\C&=1.3-0.9\\C&=0.4\:\rm{mg}\end{aligned}\)
Company A has \(1.3\) milligrams, which is twice the difference between the weight of Company B's supply and Company C's.
So, its expression is given as,
\(A=2(B-C)\\\)
Substituting values of \(A,C\), the expression becomes,
\(\begin{aligned}1.3&=2(B-0.4)\\0.65&=B-0.4\\B&=0.65+0.4\\B&=1.05\:\rm{mg}\end{aligned}\)
So, the hospital gets,
\(\begin{aligned}A+B+C&=1.3+0.4+1.05\\&=2.75\:\rm{mg}\end{aligned}\)
of medicines.
We are required to find the total milligrams if medicine the hospital can get from the three companies.
The total quantity of medicine the hospital can get from the three companies is 2.75 milligrams
There are there companies:
Company A
Company B
Company C
Company A = 1.3 milligrams
Company A is 0.9 milligrams more than Company C's
A = 0.9 + C
1.3 = 0.9 + C
1.3 - 0.9 = C
0.4 = C
C = 0.4 milligrams
Company A is also twice the difference between the weight of
Company B's supply and Company C's
A = 2(B - C)
1.3 = 2(B - 0.4)
1.3 = 2B - 0.8
1.3 + 0.8 = 2B
2.1 = 2B
Divide both sides by 2
B = 2.1/2
B = 1.05 milligrams
Therefore,
A + B + C
= 1.3 + 1.05 + 0.4
= 2.75 milligrams

A school supervisor wants to determine the percentage of students that bring their lunch to school. What method would assure random selection of a sample population?
Answers
To assure the random selection of a sample population for determining the percentage of students who bring their lunch to school, a method known as simple random sampling can be employed.
Simple random sampling is a technique that provides each member of the population an equal chance of being selected for the sample. Here's an explanation of how simple random sampling can be implemented in this scenario:
Define the population: The school supervisor needs to clearly define the population of interest, which would be all the students in the school.Assign a unique identifier: Each student should have a unique identifier, such as a student ID number, to differentiate them from one another.Generate a sampling frame: A sampling frame is a list of all the unique identifiers of the students. This could be obtained from the school's records or databases.Determine the sample size: The school supervisor needs to decide on the desired sample size, ensuring it is representative of the population while being practical to manage.Use a random selection method: Employ a random selection method, such as using a random number generator or a random number table, to select the required number of unique identifiers from the sampling frame.Contact selected students: Once the sample has been selected, the chosen students can be contacted to participate in the survey or data collection regarding whether they bring their lunch to school.know more about percentage here:

Which of the following is true for the function f(x)=2cos(x2)
a. The period is π
b. The period is π2
c. The period is 2π
d. The period is 4π
e. The period is 2
Answers
Answer:
c. The period is 2π
Step-by-step explanation:
The period of a function is the smallest value of $p$ for which\( f(x+p) = f(x)\) for all x.
For the function f(x) = 2cos(x^2), we can see that f(x+2π) = f(x) for all x.
This is because the cosine function has a period of 2π. Therefore, the period of f(x) = 2cos(x^2) is \(\boxed{2\pi}\)

Answer:
H
Step-by-step explanation:
Firstly, G and J cannot be the answers because the beginning numbers are too big. If you look at the fractions, you can see 2 and 7/8 because 2 is the smallest of all of them. Now the answer is between F and H.
In F, the second number is 3 and 1/2.
In H, the second number is 3 and 1/4.
If you want to make it an improper fraction to visualize better, it would be 7/2 and 12/4=6/2. Or you can just compare to see which is smaller, 1/2 or 1/4. In this case, 3 and 1/4 is smaller. Therefore the answer is H.

Graph each function for the given domain
Answers
Evaluating the function in the values of the domain we will get some coordinate pairs. The graph of these is in the image at the end.
How to graph the function in the given domain?Here we have the function:
3x - y = 1
And we want to graph this in the domain (-3, -1, 0, 4)
To do so, we need to evaluate the function (the values of x) in the values of the domain.
Solving the equation for y we get:
y = 3x - 1
Now, when x = -3
y = 3*-3 - 1 = -10
when x = -1
y = 3*-1 - 1 = -4
when x = 0
y = 3*0 - 1 = -1
When x = 4
y = 3*4 - 1 = 11
So we have the points (-3, -10), (-1, -4), (0, -1), (4, 11)

= 11/20 + 2/20 = 13/20
