Answer:
2,810 feet
Step-by-step explanation:
Take a look at the diagram
There are two triangles formed with a common side AB
AB represents the vertical height of the plane = 5150 feet
AC represents the distance of car 1 from O
In ΔABC, m∠A = 90°, m∠ABC = 38°
Since the three angles of triangle must add up to 180°
90 + 38 +m∠C = 180
128 + m∠C = 180°
m∠C = 180 - 128 = 52°
In a right angle triangle where one side is the angle ∅, the ratio of the side opposite this angle to the side adjacent to the angle is tan∅
Using the values provided we get
tan(52°) = 5150/AC
AC= 5150/tan(52) = 4,023.62 feet ≈ 4024 feet
This is the horizontal distance of the first car from the plane
Similarly for ΔABD
m∠D = 180 - (90 + 53) = 37°
tan(37) = 5150/AD
AD= 5150/tan(53) = 6,834.28 feet ≈ 6834 feet
This is the horizontal distance of the second car from the plane
The distance between the two cars = 6,834 - 4,024
= 2,810 feet

The number of salespeople assigned to work during a shift is apportioned based on the average number of customers during that shift. Apportion 21 salespeople using Hamiltons method given the information below
Hamilton's method of allocating can be used to assign the 21 salespeople in the table in the following order:
2, 5, 6, 8.
What do you mean by Hamilton's method of apportioning?Alexander Hamilton was the one who first suggested the strategy that now carries his name. In 1791, Congress approved of his strategy, but President Washington disapproved of it. It was commonly used from 1852 through 1911. He begins by figuring out exactly how many objects each group requires.
We'll use the terminology of shift and hours since the relevant question is about the allocated salesperson in order to calculate the appropriate number of salespeople for each shift.
Now total no. of customers given = 125 + 305 + 439 + 515 = 1375
Now total no of salesperson available = 21.
So, the divisor = 1375/21 = 65.47
Hamilton's approach is now used to determine the number of salespeople assigned by dividing the average number of customers per shift by the divisor.
So, the salesperson assigned are:
Morning = 125/65.47 = 2
Midday = 305/65.47 = 5
Afternoon = 430/65.47 = 6
Evening = 515/65.47 = 8 (Decimals rounded according to Hamilton's principle).

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the distance Luciano walked more on Sunday be A
Now , the equation will be
The distance walked by Luciano on Sunday = ( 5/9 ) mile
The distance walked by Luciano on Saturday = ( 7/18 ) mile
So , the distance Luciano walked more on Sunday A = distance walked by Luciano on Sunday - distance walked by Luciano on Saturday
Substituting the values in the equation , we get
The distance Luciano walked more on Sunday A = ( 5/9 ) - ( 7/18 )

In 1994, the city of Amuel had a population of 1,256 people. That same year a factory opened near the town, and many people moved into the city limits. The population grew to 1,381 people in 1995, and in 1996 the population of Amuel reached 1,519 people. Assume this rate of growth continued until the factory closed in 2007. How many people were living in Amuel when the factory closed? Explain. Round to the nearest whole number, if needed.
Answer:
4604 (when rounded to the nearest whole number)
Step by step explanations:
Using the exponential growth formula, we can determine Amuel's population at the time the factory shut down: N = N0 * e^(rt) (rt) Where r is the growth rate, t is the number of years the growth takes place, N is the ultimate population, N0 is the starting population, and r represents growth.
We may use the population data from 1995 and 1996 to get the growth rate: r = ln(1,381 / 1,256) / (1996 - 1995) (1996 - 1995)
Putting the numbers in: r = 0.117
Next, we determine how many years the growth took place: t = 13 years (2007 - 1994) Lastly, we enter the values into the formula as follows: N = 1,256 * e^(0.117 * 13)
Calculating the answer, we discover: 4,604 persons (N = 1,256 * 3.63) Consequently, there were about 4,604 residents there when the facility shut down in 2007.

What is the side length of the field at the end of two years? Explain and show your work
The side length of the field after two years (24 months) would be 46368.
How to determine the side length of the fieldThe Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, starting from 0 and 1: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...
To determine the side length of the field after two years, we can calculate the number of rabbit pairs after two years.
At the end of the first month, there is 1 pair of rabbits.
At the end of the second month, there are 1 + 1 = 2 pairs of rabbits.
At the end of the third month, there are 1 + 1 = 2 pairs of rabbits.
At the end of the fourth month, there are 2 + 1 = 3 pairs of rabbits.
At the end of the fifth month, there are 3 + 2 = 5 pairs of rabbits.
At the end of the sixth month, there are 5 + 3 = 8 pairs of rabbits.
At the end of the seventh month, there are 8 + 5 = 13 pairs of rabbits.

The determinant is a scalar value which is associated with the square matrix. If X is a matrix, then the determinant of a matrix is denoted by |X|. Inverse of matrix A is calculated by using formula as below,
A = adj(A)/|A|. As we see a matrix A is invertible if and only if it has non-zero determinant. Also for a diagonal matrix its determinant is product of diagonal entries here diagonal entries are again matrices so |A|=|B|×|C|.

In formally proving that lim…….
The value of m in the limit is (-13 + sqrt(169 + 4ε)) / 2, where -84.875 < ε < 1.
What is the value of mTo prove that lim as x approaches 6 of (x^2+x) = 42, we need to find a δ > 0 such that if 0 < |x - 6| < δ, then |(x^2+x) - 42| < ε, where ε > 0 is arbitrary.
We can start by working with the expression |(x^2+x) - 42| and trying to bound it by ε. We have:
|(x^2+x) - 42| = |x^2 + x - 6^2 - 6 + 36| = |(x-6)(x+7)|.
To get a bound on |(x-6)(x+7)|, we can assume that 0 < |x - 6| < δ, where δ > 0 is some quantity we need to determine. This means that:
|x-6| < δ.
We can then use the triangle inequality to bound |x+7| as follows:
|x+7| <= |x-6| + |13| < δ + 13.
Thus, we have:
|(x-6)(x+7)| <= |x-6|*|x+7| < δ(δ+13).
Now, we want to choose δ such that δ(δ+13) < ε. Let's choose:
δ = min(ε/m, 1),
where m is some constant we need to determine. We want to make sure that this choice of δ satisfies δ(δ+13) < ε.
Substituting δ = min(ε/m, 1) into the inequality δ(δ+13) < ε, we get:
min(ε/m, 1)(min(ε/m, 1) + 13) < ε.
Simplifying this inequality gives:
min(ε/m, 1)^2 + 13min(ε/m, 1) - ε < 0.
Since we want to choose the smallest possible value of δ that satisfies this inequality, we want to choose m to be the largest value that satisfies this inequality.
The discriminant of the quadratic equation is:
b^2 - 4ac = 13^2 + 4ε.
Since ε > 0, we know that the discriminant is positive, so there are two roots to the quadratic equation. The largest root is:
(-13 + sqrt(169 + 4ε)) / 2.
So, we can choose:
m = (-13 + sqrt(169 + 4ε)) / 2.
Then, we have:
min(ε/m, 1) = ε/((-13 + sqrt(169 + 4ε)) / 2).
Substituting this value of δ into the inequality δ(δ+13) < ε, we get:
ε^2 / (13 - sqrt(169 + 4ε)) < ε.
This simplifies to:
ε < 13 - sqrt(169 + 4ε).
Squaring both sides and rearranging, we get:
4ε^2 + 338ε - 1444 < 0.
This quadratic inequality holds if and only if:
(-338 - sqrt(338^2 + 441444)) / (24) < ε < (-338 + sqrt(338^2 + 441444)) / (24).
Simplifying this gives:
-84.875 < ε < 1.375.
Thus, we have found that if we choose:
m = (-13 + sqrt(169 + 4ε)) / 2,
where:
-84.875 < ε < 1.

Nancy wants to share some money between three different charities. She
splits £370 into three amounts that she calls A, B and C.
The ratio A: Bis 2: 5.
The ratio A: C is 3:8.
Work out how much money C represents.
Step-by-step explanation:
To find the amount of money represented by C, we need to find the value of A and B first.
Since the ratio A:B is 2:5, we can assume that B is 5 times the amount of A.
Let's assume the amount of money represented by A is x.
Then B = 5x and C = 8x.
We know that the total amount of money split is £370, so we can write an equation:
x + 5x + 8x = £370
14x = £370
x = £26.43
So, the amount of money represented by C is 8x = 8 * £26.43 = £211.44
