plum island lighthouse, shines a light from a height of 34 feet with a 2 degree angle of depression. how far out can this light reach into the harbor?
Answers
Plum Island Lighthouse can light up the harbor 974.44 feet away from its base.
The angle of depression refers to the angle at which an observer is looking down from an object to a point of reference below. If the angle of depression is increased, the distance from the object to the point of reference decreases. When there is a 2-degree angle of depression, the following formula is used to determine the distance between the observer and the point of reference (in this case, the harbor):tan θ = opposite/adjacent
where θ is the angle of depression, opposite is the height of the object, and adjacent is the distance between the object and the point of reference. Tan 2 = 34/x where x is the distance between the lighthouse and the harbor.tan 2 = 0.03492The angle of depression must be converted to radians to use a calculator.θ = 2π/360 = 0.03491 radians
Therefore,34/x = 0.03492x = 34/0.03492 = 974.44 feet.

Shaila is riding on a rollercoaster when her phone falls out of her pocket. The phone followed the equation y=−16t2+400
where y
gives the height of the phone after t
seconds. How long did it take her phone to hit the ground?
The phone hit the ground after seconds.
Answers
Answer:
5 seconds
Step-by-step explanation:
when the phone hits the ground then y = 0 , that is
- 16t² + 400 = 0 ( subtract 400 from both sides )
- 16t² = - 400 ( divide both sides by - 16 )
t² = 25 ( take square root of both sides )
t = [tex]\sqrt{25}[/tex] = 5
the phone hits the ground after 5 seconds
Answer:
5 seconds
Step-by-step explanation:
y = [tex]-16t^{2} + 400 \\[/tex]
Make t the subject:
[tex]16t^{2} = -400\\t^{2} = \frac{400}{16} = 25\\ t = \sqrt{25} = 5[/tex]

If you are solving the area of a trapezoid or a triangle, you multiply the base and the height. BUTTTT, I don't know if you divide the "area" by 2 to find the answer because the area solves two next to each other ALWAYS, or you do it depending on how many trapezoids are in the problem.
Answers
Answer:
When calculating the area of a triangle, you multiply the base by the height and then divide the result by 2. This is because a triangle is half of a parallelogram or a rectangle, and these shapes have an area equal to base times height. By dividing by 2, you are finding half of the area of the parallelogram or rectangle.
For a trapezoid, you can find the area by taking the average of the bases and multiplying it by the height. So the formula for the area of a trapezoid is A = (b1 + b2)h/2, where b1 and b2 are the lengths of the two parallel bases and h is the height. There is no need to divide the result by 2 because the formula already takes the average of the bases into account.

At a school of 550 children 80% walk to school
Answers
If at a school of 550 children 80% walk to school, the 110 children come to school by other means.
If 80% of the children walk to school, then the remaining 20% of children must arrive at school by other means (such as being driven by a parent, taking public transportation, etc.).
To find out how many children come to school by other means, we can use the following formula:
Number of children who come to school by other means = Total number of children x Percentage who don't walk to school
In this case, we have:
Number of children who come to school by other means = 550 x 20% = 110
Therefore, 110 children come to school by other means.

Gene expression occurs through transcription and then translation. From the given list, select all that pertain to transcription. Transcription is the process of converting DNA into RNA. The following are the items that are included in transcription: Using DNA as a template Using RNA polymerase Creation of mRNA Reading codons The RNA polymerase enzyme is responsible for catalyzing the formation of phosphodiester bonds between nucleotides that have been added to the growing RNA chain.
The RNA polymerase enzyme binds to the promoter region of a gene before unwinding the DNA helix and beginning transcription. In transcription, the DNA template strand is read by RNA polymerase in the 3′-to-5′ direction, but RNA is synthesized in the 5′-to-3′ direction. RNA polymerase reads the DNA template strand in the 3′-to-5′ direction, synthesizes the mRNA transcript in the 5′-to-3′ direction, and produces a new RNA molecule that is complementary to the DNA template strand. Thus, transcription is responsible for creating a single-stranded RNA molecule called messenger RNA (mRNA).Therefore, the correct answer is:

The first 36 cupcakes cost $1 each, and all cupcakes after that cost $1.50 each.
Answers
Answer: The first 24 cupcakes cost $1.50 each, and all cupcakes after that cost $1 each.
Step-by-step explanation:
The graph shows two pieces of the function, with one increasing from the point (0, 0) through the point (12, 18) to the endpoint (24, 36) and the other increasing from the point (24, 36) through the point (48, 60) to the right.
This means that the first 24 cupcakes cost $1.50 each and all cupcakes after that cost $1 each, as shown by the first piece of the function. The second piece of the function shows that the price per cupcake does not increase after 36 cupcakes, so option 3 and option 4 can be eliminated.
Therefore, the correct answer is: The first 24 cupcakes cost $1.50 each, and all cupcakes after that cost $1 each.

How do you decide what numbers to use as the numerator and the denominator in each equivalent fraction to the given decimal?
Answers
Answer:
To convert a decimal to an equivalent fraction, we need to first determine the place value of the decimal. For example, a decimal that ends in the tenths place (such as 0.4) has a denominator of 10. A decimal that ends in the hundredths place (such as 0.25) has a denominator of 100.
Once we have determined the denominator, we can convert the decimal to a fraction by placing the digits of the decimal in the numerator and the denominator. For example, 0.4 can be converted to the fraction 4/10. We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which in this case is 2. So 4/10 simplifies to 2/5.
In general, to convert a decimal to a fraction, we can follow these steps:
1. Determine the denominator based on the place value of the decimal.
2. Place the digits of the decimal in the numerator and the denominator.
3. Simplify the fraction by dividing both the numerator and denominator by their greatest common factor.
It's important to note that sometimes decimals can be rounded, so the resulting fraction may not be exact. In such cases, we can use approximations or continue to simplify the fraction until we reach a desired level of accuracy.

Odero sold a suit for 960 making a loss of 20% for how much would he have sold it to make a profit of 20%
Answers
From the given information provided, Odero would have had to sell the suit for 1224 to make a profit of 20%.
If Odero sold a suit for 960 and made a loss of 20%, it means his selling price was only 80% of the cost price. We can use this information to find his cost price:
Cost price = Selling price / (1 - Loss%)
Cost price = 960 / (1 - 0.20)
Cost price = 960 / 0.80
Cost price = 1200
Therefore, Odero's cost price for the suit was 1200.
Now, we need to find the selling price that would give him a profit of 20%. Let's call this selling price S:
Profit% = (Selling price - Cost price) / Cost price × 100
20% = (S - 1200) / 1200 × 100
2 = (S - 1200) / 12
S - 1200 = 24
S = 1224

The solutions to the equation [tex]15z^2 +6z -8 =4z[/tex] are z = 2/3 or z = -4/5.
To solve the quadratic equation [tex]15z^2 +6z -8 =4z[/tex], we first need to rearrange it into standard form:
[tex]15z^2 + 2z - 8 = 0[/tex]
Now we can apply the quadratic formula:
z = (-b ± √(b² - 4ac)) / 2a
where a = 15, b = 2, and c = -8.
Plugging in these values, we get:
z = (-2 ± √(2² - 4(15)(-8))) / (2(15))
z = (-2 ± √(4 + 480)) / 30
z = (-2 ± √484) / 30
z = (-2 ± 22) / 30
So z equals either (-2 + 22)/30 = 2/3 or (-2 - 22)/30 = -4/5.

what is the probability of getting all tails? express your answer as a simplified fraction or a decimal rounded to four decimal places.
Answers
The probability of getting all tails when flipping a coin three times can be calculated using the multiplication rule of probability. For each flip of the coin, there are two possible outcomes: heads or tails.
Assuming the coin is fair, both outcomes are equally likely, so the probability of getting tails on any one flip is 1/2.
To calculate the probability of getting all tails in three flips, we need to multiply the probabilities of getting tails on each individual flip. Since the flips are independent events (i.e. the outcome of one flip does not affect the outcome of another flip), we can simply multiply the probabilities together:P(all tails) = P(tails on first flip) x P(tails on second flip) x P(tails on third flip)
= (1/2) x (1/2) x (1/2)
= 1/8
Therefore, the probability of getting all tails when flipping a coin three times is 1/8 or 0.125 when expressed as a decimal rounded to four decimal places.

jordan wants to create an equiangular octagon whose side lengths are exactly the first 8 positive integers, so that each side has a differetn length. how many such octagons can jordan create
Answers
There is only one equiangular octagon that Jordan can create with side lengths as the first 8 positive integers.
To create an equiangular octagon with side lengths as the first 8 positive integers, each side must have a different length. The sum of the interior angles of an octagon is 1080 degrees, so each angle in the octagon must measure 135 degrees.
If we arrange the 8 integers in decreasing order, we can label the longest side as a and the remaining sides as b1, b2, b3, b4, b5, b6, in descending order. Then, we must have:
a + b1 + b2 = a + b2 + b3 = a + b3 + b4 = a + b4 + b5 = a + b5 + b6 = a + b6 + b1 = 135 degrees
Simplify each equation, we get:
b1 - b3 = b2 - b4 = b3 - b5 = b4 - b6 = b5 - b1 = b6 - a
Since all the side lengths are different, we can use these equations to find all possible combinations of side lengths. By inspection, we can see that there is only one set of side lengths that satisfies these conditions, namely:
a = 8
b1 = 7
b2 = 6
b3 = 5
b4 = 4
b5 = 3
b6 = 2

What is a function?
A function is a relationship or expression involving one or more variables. It has a set of input and outputs.
The graph of the function f(x) = 0.8x is a straight line with slope 0.8 passing through the origin (0, 0). The graph of the function g(x) = ⌊x⌋ is the collection of all points (x, y) where y is the greatest integer less than or equal to x. This function is not continuous and has a discontinuity at each integer.
To find the intersections between the two graphs, we need to determine where the values of f(x) and g(x) are equal.
we need to find the integer values of x where 0.8x and x are equal.
0.8x = x
0.2x = 0
x = 0
Thus, the two graphs intersect at the point (0, 0). There are no other intersections between the two graphs, since they have different slopes and one is continuous while the other is not. Therefore, the answer is one intersection.

2. Use a proof by mathematical induction to show that your equation from question 1 applies to the minimum number of moves required to defeat the Tower of Hanoi game, based on the number of disks you must move. Think about the process of the game; and describe how your equation applies to it.
Answers
The minimum number of moves required to complete the Tower of Hanoi game is related to the number of disks, and can be described by the equation m = [tex]2^n - 1[/tex].
Let n be the number of disks and m be the minimum number of moves required to complete the Tower of Hanoi game. Renae's observations suggest that the equation m = [tex]2^n - 1[/tex] describes this pattern.
When n=1, the minimum number of moves required to complete the game is m=1. Plugging this value into the equation m=[tex]2^n-1[/tex]gives m=[tex]2^1-1[/tex]=1. Therefore, the equation holds true for n=1.
Assume that the equation holds true for n=k. That is, m=[tex]2^k-1[/tex] is the minimum number of moves required to complete the game with k disks.
Now, consider the case where n=k+1. This requires a minimum of m=[tex]2^k-1[/tex] moves, according to the equation. Then, the largest disk can be moved to the ending peg in one move. Finally, the k disks that were moved to the spare peg must be moved to the ending peg, which requires another minimum of m=[tex]2^k-1[/tex] moves.
Thus, the total minimum number of moves required to complete the game with k+1 disks is:
m = [tex]2(2^k-1) + 1[/tex]
m = [tex]2^(k+1) - 2 + 1[/tex]
m = [tex]2^(k+1) - 1[/tex]
This is the same as the equation we started with, but with k+1 in place of n. Therefore, the equation holds true for all positive integers n by mathematical induction.
