Answer:
The total profit the company would make over the course of its first 14 years of operation is approximately $2,562,841.
Step-by-step explanation:
The profit of the company increased at a constant 20% per year. We can use the formula for the future value of an investment to calculate the profit for each year, where:
FV = PV x (1 + r)^n
FV is the future value of the investment
PV is the present value of the investment
r is the annual interest rate
n is the number of years
Using this formula, we can find the profit for each year:
Year 1: $140,000
Year 2: $168,000
Year 3: $201,600
Year 4: $241,920
Year 5: $290,304
Year 6: $348,364
Year 7: $418,037
Year 8: $501,644
Year 9: $601,972
Year 10: $722,367
Year 11: $866,840
Year 12: $1,040,208
Year 13: $1,248,250
Year 14: $1,497,900
To find the total profit over the course of the first 14 years, we can simply add up the profits for each year:
Total profit = $140,000 + $168,000 + $201,600 + $241,920 + $290,304 + $348,364 + $418,037 + $501,644 + $601,972 + $722,367 + $866,840 + $1,040,208 + $1,248,250 + $1,497,900
Total profit = $2,562,841 (rounded to the nearest whole number)

recursive rule for 1, .5, 0, -5,....
The sequence generated recursively by the rule is 1, 0.5, 0, -5, -2.5, 2, 7.25, ...
Describe Recursive Rule?A recursive rule is a mathematical rule that describes how to calculate the value of a term in a sequence or function based on the values of previous terms. In other words, a recursive rule defines a sequence or function in terms of itself.
To apply a recursive rule, we start with one or more initial terms and then use the rule to generate the subsequent terms. The rule involves a formula that expresses each term in the sequence or function as a function of the previous terms. This process continues indefinitely, generating an infinite sequence or function.
Recursive rules are often used in mathematics to define sequences and functions that have a recursive structure, such as the Fibonacci sequence or the factorial function. They can also be used to define algorithms for solving problems in computer science and other areas.
One advantage of recursive rules is that they can provide a concise and elegant way of defining complex sequences or functions. However, they can sometimes be difficult to work with, as they can lead to complicated and recursive formulas that are hard to evaluate or simplify.
To generate the sequence 1, 0.5, 0, -5, ... recursively, we can use the following rule:
a_n = (a_{n-1} - 3a_{n-2})/2
where a_n represents the nth term in the sequence.
Using this rule, we can generate the sequence as follows:
a_1 = 1 (given)
a_2 = 0.5 (given)
To find the next term, we use the recursive rule:
a_3 = (a_2 - 3a_1)/2 = (0.5 - 3(1))/2 = -1
Continuing in the same way, we can find the next terms:
a_4 = (a_3 - 3a_2)/2 = (-1 - 3(0.5))/2 = -2.5
a_5 = (a_4 - 3a_3)/2 = (-2.5 - 3(-1))/2 = 2
and so on. Thus, the sequence generated recursively by the rule is 1, 0.5, 0, -5, -2.5, 2, 7.25, ...

The amount of tip that Ethan receives on every order, we can use the formula Tip amount = (Tip percentage) x (Cost of order) and plug in the values accordingly.
To calculate the amount of tip that Ethan receives on every order, we can use the formula:
Tip amount = (Tip percentage) x (Cost of order)
In this case, the tip percentage is `15\%` and the cost of order is the variable we need to find.
Let's assume that the cost of an order is $100. Using the formula above, we can calculate the amount of tip that Ethan receives:
Tip amount = (`15\%`) x ($100)
Tip amount = $15
Therefore, Ethan receives a $15 tip on an order that costs $100.
If the cost of an order is different, we can simply plug in the new value into the formula and calculate the tip amount accordingly. For example, if the cost of an order is $50, the tip amount would be:
Tip amount = (`15\%`) x ($50)
Tip amount = $7.50
In conclusion, to calculate the amount of tip that Ethan receives on every order, we can use the formula Tip amount = (Tip percentage) x (Cost of order) and plug in the values accordingly.

Find the solution of the given differential equation satisfying the indicated initial condition.y′=−2,y(0)=−8
The function that satisfies the differential equation y′ = -2 with initial condition y(0) = -8 is y = -2x - 8.
To solve the differential equation y′ = -2 with initial condition y(0) = -8, we need to find the function y(x) that satisfies both the differential equation and the initial condition.
We can start by integrating both sides of the differential equation with respect to x:
∫y′ dx = ∫(-2) dx
y = -2x + C
where C is a constant of integration.
To find the value of C, we can use the initial condition y(0) = -8:
y(0) = -2(0) + C = C = -8
So the solution to the differential equation with initial condition is:
y = -2x - 8
Therefore, the function that satisfies the differential equation y′ = -2 with initial condition y(0) = -8 is y = -2x - 8.

The first, second and third terms of a geometric progression are the first, fourth and tenth terms, respectively,
of an arithmetic progression. Given that the first term in each progression is 12 and the common ratio of the geometric progression is r, where r # 1, find:
a) the value of r
b) the sixth term of each progression
Answer:
a) r = 2
b)
GP a₆ = 384
AP a₆ = 32
Step-by-step explanation:
First term a₁ = 12 for both progressions
r = common ratio, d = common difference
nth term of geometric progression = a₁ x rⁿ⁻¹
nth term of arithmetic progression = a₁ + (n - 1)d
Second term of GP = Fourth term of AP
=> 12r¹ = 12 + 3d
==> 12r = 12+ 3d (1)
Third term of GP = 10th term of AP
=> 12r² = 12 + 9d (2)
3 x (1) => 3(12r = 12 + 3d) => 36r = 36 + 9d (3)
(2) - (3) gives12r² -36r = 12 - 36
12r² - 36r = 12 + 9d - (36 + 9d)
12r² -36r = -24
12r² -36r + 24 = 0
Dividing by 12 gives
r² - 3r + 2= 0
We can factor r² - 3r + 2 as (r - 1)(r-2)
r² - 3r + 2= 0
=> (r - 1)(r-2) = 0
=> r = 1 or r = 2
r cannot be 1 since all terms of the GP will be equal with a common ratio of 1
Therefore r = 2 (Part a)
Using equation (1) we get:
12r = 12+ 3d
12 x 2 = 12 + 3d
24 = 12 + 3d
3d = 24 - 12 = 12
d = 12/3 = 4
So the common ratio, r, is 2. Common difference d = 4
6th term of GP =12 x r⁵ = 12 x 2⁵ = 12 x 32 = 384
6th term of Ap = 12 + 5d = 12 + 5(4) = 12 + 20 = 32

The compound probability is P(R and then R) = P(R) x P(R|R) = (3/10) x (2/9) = 0.0667 or 6.67% (rounded to two decimal places)
Describe Probability?Probability is a measure of the likelihood or chance that an event will occur. It is a mathematical concept used to quantify the degree of uncertainty of a particular outcome in a random process.
The probability of an event occurring is expressed as a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain to occur. The probability of an event occurring can also be expressed as a percentage, with 0% indicating that the event is impossible and 100% indicating that the event is certain to occur.
The calculation of probability involves determining the number of possible outcomes that satisfy the condition of interest and dividing that number by the total number of possible outcomes in the sample space.
For example, if you toss a fair coin, the probability of getting heads is 0.5 or 50%, since there are two possible outcomes (heads or tails), and each outcome is equally likely. Similarly, if you roll a fair six-sided die, the probability of getting a 4 is 1/6 or approximately 0.167, since there is only one possible outcome of rolling a 4, out of six possible outcomes.
Probability is used in various fields, such as statistics, economics, engineering, and science, to analyze data, make predictions, and make decisions based on uncertain outcomes. It is an essential concept in many areas of study, and its applications are widespread.
Let's denote the events as follows:
R = selecting a red marble
B = selecting a blue marble
W = selecting a white marble
a) The probability of selecting a blue marble on the first draw, followed by a red marble on the second draw:
The probability of selecting a blue marble on the first draw is 6/10 (since there are 6 blue marbles out of a total of 10 marbles). If a blue marble is selected on the first draw, then there are 9 marbles left in the box, including 3 red marbles. The probability of selecting a red marble on the second draw, given that a blue marble was selected on the first draw, is 3/9. Therefore, the compound probability is:
P(B and then R) = P(B) x P(R|B) = (6/10) x (3/9) = 0.2 or 20%
b) The probability of selecting a white marble on the first draw, followed by a blue marble on the second draw, followed by a red marble on the third draw:
The probability of selecting a white marble on the first draw is 1/10. If a white marble is selected on the first draw, then there are 9 marbles left in the box, including 6 blue marbles. The probability of selecting a blue marble on the second draw, given that a white marble was selected on the first draw, is 6/9. If a blue marble is selected on the second draw, then there are 8 marbles left in the box, including 3 red marbles. The probability of selecting a red marble on the third draw, given that a white marble was selected on the first draw and a blue marble was selected on the second draw, is 3/8. Therefore, the compound probability is:
P(W and then B and then R) = P(W) x P(B|W) x P(R|W and B) = (1/10) x (6/9) x (3/8) = 0.025 or 2.5%
c) The probability of selecting a red marble on the first draw, followed by another red marble on the second draw:
The probability of selecting a red marble on the first draw is 3/10. If a red marble is selected on the first draw, then there are 9 marbles left in the box, including 2 red marbles. The probability of selecting another red marble on the second draw, given that a red marble was selected on the first draw, is 2/9. Therefore, the compound probability is:

The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
Let the number of miles = m.
Given that, Lola’s car can travel no more than 445 miles on one full tank of gasoline.
m ≤ 445
After filling up the tank, she traveled 163 miles in the car.
Remaining distance is:
m ≤ 445 - 163
m ≤ 282
Hence, the inequality that represents all possible values of m, the number of miles Lola can travel in the car with the remaining gasoline in the tank is m ≤ 282.

what are the angle measures of the triangle?
The angle measures of the triangle are 45°,45°, and 90°.
What is the angle measure?
When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Here, we have
Given, the triangle is a right-angle triangle.
And the sides are 7√3, 14√3, 21.
Sides are a multiple of 7.
So, divide each side by 7.
We get the sides √3, 2√3, 3.
In a 45°−45°−90° triangle, the length of the hypotenuse is twice the length of the shorter leg, and the length of the longer leg is √3 times the length of the shorter leg.
Hence, the angle measures of the triangle are 45°, 45° and 90°

Add.
8/9 + 2/3 + 1/6
Answer: 31/18.
Step-by-step explanation:
To add these fractions, we need to find a common denominator. In this case, the least common multiple of 3, 6, and 9 is 18. We can convert each fraction to an equivalent fraction with a denominator of 18, and then add the numerators:
8/9 + 2/3 + 1/6
= (8/9) * (2/2) + (2/3) * (6/6) + (1/6) * (3/3) (Multiplying each fraction by a form of 1 to obtain a common denominator of 18)
= 16/18 + 12/18 + 3/18 (Simplifying each fraction by multiplying the numerators)
= 31/18 (Adding the simplified numerators)
Therefore, the sum of 8/9, 2/3, and 1/6 is 31/18.
