Karina and Perry are cleaning up litter in the park for community service hours. Karina and Perry both claim they have covered the greatest area. Who is correct? Justify your answer using mathematical reasoning.
Answers
Answer:
Perry's claim is correct while Karina is incorrect
Step-by-step explanation:
Question is incomplete (See Attachment)
First, we need to determine the area covered by Karina and Perry
For Karina, there are 9 square boxes each of which has an area of 1 unit sq
So:
[tex]Karina = 9 * 1\ unit^2[/tex]
[tex]Karina = 9\ unit^2[/tex]
For Perry:
There are 18 square boxes, each of which has an area of 1 unit sq.
So:
[tex]Perry = 18 * 1\ unit^2[/tex]
[tex]Perry = 18\ unit^2[/tex]
Comparing both areas, we can conclude that Perry's claim is correct while Karina is incorrect

If f(x) = sin(ln(2x)), then f’(x)=
Answers
Answer:
B. cos(ln(2x))/x
Step-by-step explanation:
We know that the inverse of sin is cosine. Note, arcsin means the same thing as inverse sin:
sin(ln(2x))Because sin (a) = sin (b) --> a = arcsin (b)
Therefore: ln(2x) = arcsin(y)Solve ln(2x)=arcsin(y) for x(e^arcsin(y))/2Subsitute y = x
(e^arcsin(x))/2Therefore, we get the answer as cos(ln(2x))/xFor questions 4-5, decide whether each table of values describes a function or not.

b. 2,500 + (5.5)(6,300)
C. (2,500) (5.5) + 6,300
d. (2,500) (0.055) + 6,300
Answers
Answer:
the answer is A.
Step-by-step explanation:
took the test just now
The right expression for the salary will be 2500 + (0.055)(6300). The correct option is A.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Hank is a salaried plus commission employee. Hank has a monthly salary of $2,500 and earns a 5.5% commission on all sales.
The expression for the salary can be written as below:-
Salary = 2,500 + (0.055)(6,300)
Here part 2500 will be the fixed salary and (0.055)(6300) will be commission part.
Therefore, the right expression for the salary will be 2500 + (0.055)(6300). The correct option is A.

The manager of a movie theater randomly surveyed 50 people who entered the movie theater on Friday. The manager asked about the
type of movie each person preferred. The results of the survey are shown in the table.
Survey Results
Type of Movie Number of People
Horror
12
Comedy
15
Action
17
Drama
6
Based on the results in the table, which statement about a person who will go to this theater next Friday is true?
O A. The person is three times as likely to prefer comedy as horror.
OB. The person is twice as likely to prefer drama as horror.
o C. The person is less likely to prefer horror or drama than action.
D. The person is more likely to prefer horror or comedy than action or drama.
Answers
Answer:
D.
Step-by-step explanation:
Horror (12) + Comedy (15) = 27
Action(17) + Drama(6) = 23
27 > 23
The statement that is true is a person who will go to this theatre next Friday is more likely to prefer horror or comedy than action or drama.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
As is given that the total number of people surveyed is 50, while the table suggests the preferences of the people about the movie.
Therefore, if take the probability of a person watching a horror or comedy movie it will be,
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
[tex]\rm Probability=\dfrac{\text{Number of people preferring Horror or comedy}}{\text{Total Number of people surveyed}}\\\\Probability = \dfrac{12+15}{50} = 0.54[/tex]
The probability of a person watching an action or drama movie it will be,
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
[tex]\rm Probability=\dfrac{\text{Number of people preferring Action or drama}}{\text{Total Number of people surveyed}}\\\\Probability = \dfrac{17+6}{50} = 0.46[/tex]
Since the probability of a person watching a horror or comedy movie is more, therefore, a person who will go to this theatre next Friday is more likely to prefer horror or comedy than action or drama.
Thus, the statement that is true is a person who will go to this theatre next Friday is more likely to prefer horror or comedy than action or drama.
