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.

(a) Isla's trading cards are 125% of Lily's trading cards.

(b) Lily's trading cards are 80% of Isla's trading cards.

Given that,

There are 225 trading cards and Lily has 180 trading cards.

To calculate the percentage of Isla's trading cards compared to Lily's,

We can use this formula:

⇒ Isla's trading cards / Lily's trading cards x 100%

Plugging in the values we get:

⇒ (225 / 180) x 100% = 125%

Therefore,

Isla's trading cards are 125% of Lily's trading cards.

b) To calculate the percentage of Lily's trading cards compared to Isla's, we can use the formula:

⇒ Lily's trading cards / Isla's trading cards x 100%

The value of x, considering the angle addition postulate, is given as follows:

x = -5.

The angle addition postulate states that if two angles share a common vertex and a common angle, forming a combination, the larger angle will be given by the sum of the smaller angles.

The larger angle in this problem is QRS, hence the equation to obtain the value of x is given as follows:

3x + 93 + 66 + x = -x + 134

The doubling time for the bacteria population is approximately 2.08 hours.

The formula for exponential growth

n = \(n_0\) × 2^(t/d)

where \(n_0\) is the initial number of bacteria (at t=0)

d is the doubling time

2^(t/d) is the factor by which the population has grown since t=0.

After 12 hours, there are 2 million bacteria

Substitute the values

24,691.4 =  \(n_0\) × 2^(12/d)

24,691.4/  \(n_0\) = 2^(12/d)

ln(24,691.4/ \(n_0\)) = ln(2^(12/d))

ln(24,691.4/  \(n_0\)) = (12/d) × ln(2)

d = 12 / (ln(24,691.4/  \(n_0\))/ln(2))

Estimate that the initial number of bacteria

\(n_0\) = 2000000 / 81

= 24691.4

Substitute this into our equation for d,

d = 12 / (ln(3)/ln(2))

d ≈ 2.08 hours

Therefore, the doubling time is approximately 2.08 hours.

The product of two irrational numbers can be either rational or irrational, depending on the specific irrational numbers being multiplied.

The product of two irrational numbers can be rational or irrational.

For example, consider √2 and √2/2. Both are irrational numbers, as they cannot be expressed as a ratio of two integers.

Their product is:

The statement "secondary data should be gathered first because this type of information is less expensive to obtain" is actually false because it has already been collected, there are some important factors to consider.

Primary data is data that is collected specifically for the purpose of the research project at hand. This type of data can include surveys, interviews, experiments, and observations. On the other hand, secondary data is data that has already been collected by someone else for a different purpose.

Firstly, it's important to consider the quality of the data. Secondary data may not always be reliable or up-to-date, which could impact the accuracy of your research findings. In some cases, you may need to spend time and resources verifying the accuracy of the secondary data, which could end up being more expensive in the long run.

Additionally, it's important to consider the specific needs of your research project. Depending on your research question, primary data may be necessary to obtain the specific information you need. In other cases, secondary data may be sufficient.

Step-by-step explanation:

There are 96 ways for four people to sit in six chairs so that the leftmost chair is occupied and the rightmost is empty.

There are 4 guests and the leftmost seat is to be occupied, so there are 4  such ways to choose the occupant of that seat.

Then, for each of those 4 ways, there are 4 ways to decide the occupant for the second seat -- the remaining three people plus the possibility of that seat being empty, that makes a total of 16 ways to decide the configuration of the first two seats.

Then, for each of those 16 ways, there are 3 ways to choose the occupant for the third seat (either 3 remaining guests if the second seat was left empty, or the two remaining guests plus the possibility of leaving the 3rd seat empty). Hence, 16 times 3 is 48. For each of those ways, there are two choices for the next seat, i.e. 48 times 2 = 96, and finally one choice for the fifth seat. So in all, there are 96 ways.

As per the GDP, the percentage did the price level rise between 2016 and ​2019 is 27.5%

To calculate the percentage increase in production, we first need to find the nominal GDP for each year. Nominal GDP is the current dollar value of all goods and services produced within a country's borders during a specified period of time. We can use the GDP deflator and real GDP to calculate nominal GDP as follows:

Nominal GDP = Real GDP x GDP deflator

Using the information provided in the question, we can calculate the nominal GDP for each year as follows:

Nominal GDP in 2016 = Real GDP in 2016 x GDP deflator in 2016

Nominal GDP in 2019 = Real GDP in 2019 x GDP deflator in 2019

Once we have the nominal GDP for each year, we can calculate the percentage increase in production as follows:

Percentage increase in production = (Nominal GDP in 2019 - Nominal GDP in 2016) / Nominal GDP in 2016 x 100% = 27.5%

Let \(\(a\)\) and \(\(b\)\) be integers such that \(\(ab = 4\)\). We want to prove that \(\((a - b)^3 - 9(a - b) = 0\).\)

Starting with the left side of the equation, we have:

\(\((a - b)^3 - 9(a - b)\)\)

Using the identity \(\((x - y)^3 = x^3 - 3x^2y + 3xy^2 - y^3\)\), we can expand the cube of the binomial \((a - b)\):

\(\(a^3 - 3a^2b + 3ab^2 - b^3 - 9(a - b)\)\)

Rearranging the terms, we have:

\(\(a^3 - b^3 - 3a^2b + 3ab^2 - 9a + 9b\)\)

Since \(\(ab = 4\)\), we can substitute \(\(4\)\) for \(\(ab\)\) in the equation:

\(\(a^3 - b^3 - 3a^2(4) + 3a(4^2) - 9a + 9b\)\)

Simplifying further, we get:

\(\(a^3 - b^3 - 12a^2 + 48a - 9a + 9b\)\)

Now, notice that \(\(a^3 - b^3\)\) can be factored as \(\((a - b)(a^2 + ab + b^2)\):\)

\(\((a - b)(a^2 + ab + b^2) - 12a^2 + 48a - 9a + 9b\)\)

Since \(\(ab = 4\)\), we can substitute \(\(4\)\) for \(\(ab\)\) in the equation:

\(\((a - b)(a^2 + 4 + b^2) - 12a^2 + 48a - 9a + 9b\)\)

Simplifying further, we get:

\(\((a - b)(a^2 + 4 + b^2) - 12a^2 + 39a + 9b\)\)

Now, we can observe that \(\(a^2 + 4 + b^2\)\) is always greater than or equal to \(\(0\)\) since it involves the sum of squares, which is non-negative.

Therefore, \(\((a - b)(a^2 + 4 + b^2) - 12a^2 + 39a + 9b\)\) will be equal to \(\(0\)\) if and only if \(\(a - b = 0\)\) since the expression \(\((a - b)(a^2 + 4 + b^2)\)\) will be equal to \(\(0\)\) only when \(\(a - b = 0\).\)

Hence, we have proved that if \(\(ab = 4\)\), then \(\((a - b)^3 - 9(a - b) = 0\).\)

The equation of the function is given as:

The initial height is

Initial height = 1296 feet

So, we have:

h(t) = -16t^2 + 1296

When the ball hits the ground, the value of h(t) is 0

So, we have:

-16t^2 + 1296 = 0

This gives

-16t^2 = -1296
