The depth of water in the port at hinchinbrook is given by: d(t)= 2.6 sin (Pi over 6 t) + 13.1, where d is in meters and t is the number of hours since high tide.
Use the model to determine how many hours are there between high tides.
If high tide was at midnight, draw a graph to determine during which hours should it be safe for the boats to be in the port and between which hours they would have to stay away from the port. Justify answers mathematically
Answers
Looking at the graph, it would be safe for the boats to be in the port when the graph levels off at around 10 to 24. That's from 10 am to before 12 midnight. Then, they would have to stay away between 12 midnight to before 10 am.

Solve your formula from problem 12 for m. Then find the taxi driver’s hourly rate of his pickup rate is $2 and he charges $19.50 for a 7 - mile trip
Answers
Answer: Cost per mile m = $4.78.
Step-by-step explanation:
Since we have given that
Pick up rate = $2
Charges for a 7 mile trip = $19.50
Charges for a mile trip would be
[tex]\dfrac{19.50}{7}\\\\=2.78[/tex]
So, amount of taxi's drivers is given by
[tex]\$2.78+\$2\\\\=\$4.78[/tex]
Hence, cost per mile m = $4.78.

Simplify the expression (3x - 4) + (2x + 5).Solution: Combine like terms: 3x + 2x - 4 + 5 = 5x + 1.Solve the equation 2x + 3 = 9.Solution: Subtract 3 from both sides: 2x = 6. Divide both sides by 2: x = 3.Determine if the expressions 2x + 5 and 5 + 2x are equivalent.Solution: Since addition is commutative, the expressions are equivalent.Determine if the equations 2x + 3 = 9 and 2x + 6 = 12 are equivalent.Solution: Subtracting 3 from both sides of the first equation gives 2x = 6, which is equivalent to the second equation.Simplify the expression 2(3x + 4) - (5x - 2).Solution: Distribute the 2: 6x + 8 - (5x - 2). Use the distributive property: 6x + 8 - 5x + 2. Combine like terms: x + 10.Solve the equation 3(x - 2) = 9.Solution: Distribute the 3: 3x - 6 = 9. Add 6 to both sides: 3x = 15.

Answers
The fourth term in the arithmetic sequence 13, 10, 7 is 4.
Explanation:The arithmetic sequence 13, 10, 7 has a common difference of -3. To find the fourth term, we can start with the first term and keep subtracting the common difference. So, 13 - 3 = 10, 10 - 3 = 7, and 7 - 3 = 4. Therefore, the fourth term in the arithmetic sequence 13, 10, 7 is 4.
What is the retail price of a couch at a furniture store that has a wholesale price of $115 and is marked up by 75 percent? $86.25 $190.00 $201.25 $316.25
Answers
A percentage is a way to describe a part of a whole. The retail price of a couch at a furniture store that has a wholesale price of $115 and is marked up by 75% is $201.25.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the wholesale price of the couch at a furniture store is $115. Now, as the retail price is marked up by 75%, therefore, the new price of the couch can be written as,
The new price of the couch = 175% of the wholesale price
= 1.75 × $115
= $201.25
Hence, the retail price of a couch at a furniture store that has a wholesale price of $115 and is marked up by 75% is $201.25.

What is a number greater than 1,000 whose prime factorization contains 1 prime number that does not repeat, 1 prime number that repeats three times, and 1 prime number that repeats twice
Answers
So for the prime number that doesn't repeat, you can just say a random prime number, say like 7.
For the prime number that repeats 3 times, say like 11.
And the prime number that repeats twice, you can just say something like 13.
Then it would be 7 * 11 * 11 * 11 * 13 * 13, which the solution would be 1,574,573, above 1000.

Andrew is planning a tailgate party before the big football game. He has budgeted a maximum of $60 for hamburgers and hot dogs. Hamburgers cost $3 per pound, and hot dogs cost $2 per pound. Write an inequality to describe the possible number of pounds of hamburgers and of hot dogs he can purchase.
Answers
The inequality that describes the the possible number of pounds of hamburgers and of hot dogs he can purchase is 3x + 2y ≤ 60.
We have,
Let x be the number of pounds of hamburgers that Andrew purchases, and let y be the number of pounds of hot dogs that he purchases.
The cost of x pounds of hamburgers is 3x dollars, and the cost of y pounds of hot dogs is 2y dollars.
According to the problem, Andrew has budgeted a maximum of $60 for hamburgers and hot dogs.
Therefore, we can write the following inequality:
3x + 2y ≤ 60
This inequality describes the possible combinations of x and y that Andrew can purchase, such that the total cost of hamburgers and hot dogs does not exceed his budget of $60.
Thus,
The inequality that describes the the possible number of pounds of hamburgers and of hot dogs he can purchase is 3x + 2y ≤ 60.

Maria wrote the equation of a line that has a slope of 4/3and passes through point (3, 5). Which statement is true?
Answers
Answer:
B
Step-by-step explanation:
The slope intercept equation is [tex]y=\frac{4}{3}x+1[/tex] is true statement. Option C is correct.
From the given information the slope of the line is 4/3 and it is passing through point (3, 5).
Now, determine the equation of line in slope intercept form.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
To find the equation, first find the y intercept by considering the point values (3, 5).
[tex]5 = \frac{4}{3}+b[/tex]
[tex]5=4+b[/tex]
[tex]b=1[/tex]
Now plug in the values of slope and y intercept in slope intercept form:
[tex]y=\frac{4}{3}x+1[/tex]
Hence, Option C is correct, he equation of the line is [tex]y=\frac{4}{3}x+1.[/tex]
