Use the formula A=P (1+ r/n)ⁿ⁺ to solve the compound interest problem.
Find how long it takes a $ 1700 investment to earn $ 500 interest if it is invested at 2 % interest compounded quarterly.
$ 500 interest will be earned in approximately ___ years. (Round to the nearest tenth.)
The answer to the given problem can be stated as, "$ 500 interest will be earned in approximately 0.14 years."
What is compound interest?The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.
The formula to calculate the amount is as follows,
A = P(1 + r)^(nt)
The, the interest is given as P[(1 + r)^(nt) - 1]
Substitute all the corresponding values in the above expression to obtain,
500 = 1700[(1 + 2/100)^(nt) - 1]
=> 500 + 1700 = 1700(1 + 2/100)^(nt)
=> (1 + 2/100)^(nt) = 2200/1700
=> 1.02^(nt) = 22/17
Since, there are 4 quarters in one year, n = 4.
1.02^(4t) = 1.294
=> 4t = log(1.294) ÷ log(1.02)
=> 4t = 0.562
=> t = 0.14
Hence, it will take 0.14 years to earn the interest of $500.

The number of acres owned for which the average intake is 2200 calories per day is 2 acres obtained by the algebraic expression that relates the acres of land and the calories per day.
What is an algebraic expression?An algebraic expression is formed by variables, constants, and arithmetic operations. An algebraic expression provides the relation between the input and output variables i.e., x and f(x) respectively.Calculation:It is given that, the number of calories consumed daily by a person owing x acres of land is given by the algebraic expression,
C(x) = 270 ln(x+1) + 1900
The average intake of calories consumed per day is given by C(x) = 2200
Here x is the number of acres of land. Then, the required number of acres of land is
C(x) = 270 ln(x+1) + 1900
⇒ 2200 = 270 ln(x+1) + 1900
⇒ 270 ln(x+1) = 2200 - 1900
⇒ 270 ln(x+1) = 300
⇒ ln(x+1) = 300/270 = 10/9
Applying base 'e' on both sides, we get
⇒ (x+1) = [tex]e^\frac{10}{9}[/tex]
⇒ x+1 = 3.0377
⇒ x = 3.0377 - 1 = 2.0377
When rounding the final answer to the nearest tenths, we get x = 2 acres.
When rounding the final answer to the nearest thousand, we get x = 2.038 acres.
Thus, for an average intake of 2200 calories per day, the number of acres of land owned is approximately 2 acres.

What is meant by ratio?A ratio in mathematics demonstrates how many times one number is contained in another. For instance, the ratio of oranges to lemons in a dish of fruit is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3). Similarly, the ratio of oranges to the total amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7).
The quantities in a ratio can be of any kind, such as counts of people or things, measures of lengths, weights, or times, etc. Both numbers must be positive in the majority of situations.
Let e = the quantity of eggs Takeuru purchased.
Takeuru purchased s souffles total.
Then, as Takeuru purchased 4 times as many eggs as he used to make soufflés, e=4s.
Since Takeuru uses 3 eggs for each souffle he bakes and has 18 eggs remaining after backing, the equation is: e-3s=18.
This states that after Takeuru utilized three eggs for each souffle, there are still 18 eggs available.
There are now two equations:
e=4s
e-3s=18
When we solve for s using equation (2) and the value of e from equation (1), we get the following results: s=18
e=4s
e=4×18
e=72
Therefore, Takeuru purchased 72 eggs.

Applications of Compound interest:Compound interest may be used in a variety of situations, including increasing or decreasing population, Increasing the count of bacteria increasing an item's value, and a decrease in an item's worth.
The formula for Compound interest is given by
A = Pe^rtWhere P = Principal amount or Initial value
r = rate of interest or increase
t = time period
Here we have
The formula [tex]A = 23.1 e^{(0.0152t)}[/tex] represents the population of a US state, A, in millions, 't' years after 2000.
Here we need to solve the following questions
a. What was the population of the state in 2000
Compare the given formula with A = Pe^rt
=> [tex]23.1 e^{0.0152t} = Pe^{rt}[/tex]
=> Initial value or initial population, P = 23.1 and
rate of increase r = 0.0152
Therefore,
The population of the city in 2000 = 23.1 million
b. When will the population of the state reach 28.3 million?
As we know in 2002 the population = 23.1 million
Let's assume that after 'n' year the population will become 28.3 million
As we know Rate of increase = 0.0152
From the given formula
Population of the city after n, A = 23.1 e^(0.0152n)
As we assumed the population after n years = 28.3
=> 23.1 e^(0.0152n) = 28.3
=> e^(0.0152n) = 28.3/23.1
=> e^(0.0152n) = 1.225
Apply log on both sides
=> log e^(0.0152n) = log 1.225
=> 0.0152n log e = log 1.225
=> 0.0152n (1) = 0.0881
=> n = 0.0881/0.0152
=> n = 5.8 ≅ 6
After 6 years the population will be 28.3 million
After 6 years i.e 2000 + 6 = 2006
Therefore,
In 2006 the population will be equal to 28.3 million

Using the Standard Form, identify the y-intercept of the graph and explain how the y-intercept relates to the price of the pants and shirts
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> the price of the shirt
y ---> he price of the pants
we have that
The price of three shirts plus the price of two paints must be equal to $300
so
This is the equation of the line in standard form
Convert to slope intercept form
Isolate the variable y
subtract 3x both sides
Divide by 2 both sides
----> equation of the line in slope intercept form
Find out the x-intercept
Remember that the x-intercept is the value of x when the value of y is equal to zero
In this problem, the x-intercept is the price of the shirt when the price of the paints is equal to zero
Using the Standard Form, identify the x-intercept of the graph
The standard form is
The x-intercept is C/A
we have
so
The x-intercept is the point (100,0)
That means---> The price of the shirt is $100 when the price of the paints is equal to $0

The probability that there will be no drowning this year is 0%
and the probability that there will be at least 6 accidents this year is 0.003%
What is the probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
We have,
3 per year for every 100000 of tourists
if in a year 200000 tourists visited this resort,
Probability formula:
P(A) = f / N
P(A) = Probability of an event (event A) occurring.
f = Number of ways an event can occur (frequency)
N = Total number of outcomes possible.
so f = 3,
N = 100000
P(A) = f / N = 3/100000 = 0.00003 = 0.003%
so, the probability of the previous year is 0.003%.
0.003% = f / 200000
f = 200000 * 0.003% = 6
a) The probability that there will be no drowning this year:
P(A) = 0 / 200000 = 0
b) The probability that there will be at least 6 accidents this year:
P(A) = 6 / 200000
P(A) = 0.003%

Thus Volume v = ₋[tex]\int\limits^r_r {A(x)} \, dx[/tex]
Substitute A(x) from (1)
V = ₋[tex]\int\limits^r_r {4(r^{2}-x^{2} ) } \, dx[/tex]
⇒V = 4[r²x - x³/3 ]
⇒V = 4(r³ - r³/3) - 4(-r³ + r³/3) = 4[2 (r³ - r³/3)] = 16r³/3
The volume of the described solid S where the base is a circular disk or radius r and parallel cross sections perpendicular to the base are squares is V = 16r³/3

To help open up a jewelry store, Ann borrowed money from a bank.
She took out a personal, amortized loan for , at an interest rate of , with monthly payments for a term of years.
For each part, do not round any intermediate computations and round your final answers to the nearest cent.
If necessary, refer to the list of financial formulas.
(a) Find Ann's monthly payment.
(b) If Ann pays the monthly payment each month for the full term, find her total amount to repay the loan.
(c) If Ann pays the monthly payment each month for the full term, find the total amount of interest she will pay.
(a) Ann's monthly payment: $133.33
(b) Ann's total amount to repay the loan:$8000
(c) The total amount of interest Ann will pay:-$12000
What is amortized loan?
A loan that has planned, monthly payments that are applied to both the principle and interest accrued is known as an amortized loan.
To solve this problem, we need to use the following formula for an amortized loan:
[tex]Monthly\ payment = (Interest rate / 12) * Loan\ amount / (1 - (1 + (Interest \ rate / 12))^(-Term * 12))[/tex]
(a) Find Ann's monthly payment:
Substituting the given values into the formula, we get:
[tex]Monthly\ payment = (0.08 / 12) * 20000 / (1 - (1 + (0.08 / 12))^(-5 * 12))\\\\Monthly\ payment = 133.33[/tex]
Therefore, Ann's monthly payment is $133.33.
(b) Find Ann's total amount to repay the loan:
The total amount to repay the loan is equal to the sum of the monthly payments over the term of the loan. Since Ann's monthly payment is $133.33 and the term of the loan is 5 years, the total amount to repay the loan is equal to $133.33 * 5 * 12 = $8000.
(c) Find the total amount of interest Ann will pay:
The total amount of interest Ann will pay is equal to the total amount to repay the loan minus the loan amount. Since Ann's total amount to repay the loan is $8000 and the loan amount is $20000, the total amount of interest Ann will pay is equal to $8000 - $20000 = -$12000.
Note that the total amount of interest Ann will pay is a negative number because the loan amount is greater than the total amount to repay the loan. This means that Ann will end up paying less than the loan amount due to the amortization of the loan.
