What is simple interest?
Calculating the interest on a loan using simple interest is quick and simple. Simple interest is calculated by dividing the principle by the daily interest rate and the number of days between installments.
A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest.
P=2700, r=0.3%=0.003, t= 0.5 year
A= P(1+rt)
= 2700(1+ 0.003*0.5)
= 2700(1+ 0.0015)
= 2700(1.0015)
= 2704.05

Given, the values of an explicit function,
Let the function be,
f(n) = an² + bn + c
f(1) = a(1)² + b(1) + c
5 = a + b + c
f(2) = a(2)² + b(2) + c
8 = 4a + 2b + c
f(3) = a(3)² + b(3) + c
13 = 9a + 3b + c
On subtracting the equations, we get
5 = 5a + b
3 = 3a + b
Again, on subtracting we get
2 = 2a
a = 1
On putting the values we get,
b = 0.
a + b + c = 5

Rewrite the function by completing the square. h ( x ) = x 2 + 3 x − 18 h(x)=x 2 +3x−18
The quadratic function h (x) = x^2 + 3x − 18 by completing the square is witten as h(x) = (x + 1.5)^2 - 20.25.
We are given a quadratic function:
h (x) = x^2 + 3x − 18
We need to rewrite the function by completing the square.
We can see the coefficient of x is 3.
So, we will add and subtract the square of half that.
So, find the square of half of 3, we will get;
(3 / 2)^2 = 9 / 4 = 2.25
add and subtract the square of half of 3 from the given function, we will get;
h(x) = x^2 +3x + -18 2.25 -2.25
arrange the expression, we will get;
h(x) = (x^2 +3x +2.25) -18 -2.25
write the expression in parentheses as a square, and simplify the constant, we will get;
h(x) = (x + 1.5)^2 - 20.25
So, the square function is written as h(x) = (x + 1.5)^2 - 20.25.
Thus, the quadratic function h (x) = x^2 + 3x − 18 by completing the square is witten as h(x) = (x + 1.5)^2 - 20.25.

How to order the numbers?The 3 numbers given are:
-5
23/40

The numbers should be ordered as they appear on a number line (from left to right)
The smaller number is, obviously, the negative one, so the thing that we need to check now is what of the two fractions is smaller.
To do so, we can write them as decimals:
23/40 = 0.575
2/16 = 0.125
So the smaller one is 2/16 and then comes 23/40

population of 8 billion to increase to 9 billion.
_ years, round to the nearest whole number
It will take 37.5 years.
From the question, we have
A_0 = 8 billion
A = 9 billion.
r= 3% per year
A = A_0*e^rt
9 = 8*e^3t/100
9/8 = e^3t/100
Taking log_e both sides,
log_e 9/8 = log_e e^3t/100
9/8 = 3t/100
t = (9*100)/(8*3)
t = 37.5 years

Membership costs for belonging to a gym for a certain number of months are shown in the table below.
Answer:
y = 35.5x - 10
Step-by-step explanation:
If we graph the function with the help of the given table,
Since, there is a common difference in each term of 'cost of gym membership'
d = 61 - 25.5 = 35.5
d = 96.5 - 61 = 35.5
Graph will represent a linear function.
Let the equation of the line is,
y - y' = m(x - x')
where (x', y') is a point lying on the graph and 'm' is the slope.
Two points lying on the graph are (1, 25.5) and (2, 61).
Slope of the line =
=
= 35.5
Equation of the line passing through (1, 25.5) having slope 'm' = 35.5
y - 25.5 = 35.5(x - 1)
y = 35.5x - 35.5 + 25.5
y = 35.5x - 10
Here x = duration of membership
y = membership price
Therefore, equation representing Fit Zoom's membership price equation will be,
y = 35.5x - 10
The half-life of carbon-14 is 5600 years. If a piece of charcoal made from the wood of a tree shows only 73% of
in the carbon-14 expected in living matter, when did the tree die?
The tree died about ] years ago.
Do not round until the final answer. Then round to the nearest whole number.)
Answer:
Time 2 540 years
Step-by-step explanation:
T = 5 600 yares - Half-life
73% - Carbon content
N = 0.73·N₀
Decay constant:
λ = ln 2 / T = 0.693 / 5600 ≈ 0.000124 (years)⁻¹
Law of radioactive decay:
N = N₀·e^(-λ·t)
0.73·N₀ = N₀·e^(-λ·t)
0.73 = e^(-λ·t)
ln (0.73) = -λ·t
t = ln (0.73) / (-λ) = ln (0.73) / (- 0.000124) ≈ 2 540 years
un ciclista recorre 300 metros por minuto. ¿cuantos kilómetros recorre en una hora?
Answer:
El ciclista recorre en una hora:
18 kilómetros.
Step-by-step explanation:
1 hora = 60 minutos
1 minuto = 1/60 = 0.01667 horas
1 kilómetro = 1000 metros
300 metros = 300/1000 = 0.3 kilómetros
Entonces:
300 metros por minuto = 300metros/minuto
300 metros / minuto = 0.3kilómetros / 0.01667 horas
= 0.3/0.01667
= 18 kilómetros/hora

In outer space, the distant an object travels varies directly with the amount of time it travels. If an asteroid travels 3000 miles in 6 hours, how far could the asteroid travel in 9 hours?
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
3000 miles = 6 hours
4500 miles = 9 hours
The distance asteroid travel in 9 hours is 4500 miles
What is a unit rate?Unit rate is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
3000 miles = 6 hours
Divide both sides by 6.
500 miles = 1 hour
Multiply 9 on both sides.
9 x 500 miles = 9 hours

Write an equation for the nth term of the arithmetic sequence
The equation for the nth term of the arithmetic sequence is [tex]a_{n}[/tex] = 25 - 4n
The nth term of the arithmetic sequence:An arithmetic sequence or arithmetic progression is a series of numbers with a common difference. For example 1, 2, 3, 4... is an Arithmetic sequence with a common difference 1. In an Arithmetic sequence, the difference between every two consecutive terms will be equal.
The formula for the nth term of a sequence is given below
=> [tex]a_{n}[/tex] = a + (n-1)d
where a is the first term and d is a common difference.
Here we have
21, 17, 13 ... is the arithmetic sequence
Where first term a = 21
and common difference d = term2 - term1 = 17 - 21 = - 4
As we know the nth term of AP, [tex]a_{n}[/tex] = a + (n-1)d
=> [tex]a_{n}[/tex] = 21 + (n-1)(-4)
=> [tex]a_{n}[/tex] = 21 - 4n + 4

Suppose Tom borrows $4000 at an interest rate of 3% compounded each year.
Assume that no payments are made on the loan.
Follow the instructions below. Do not do any rounding.
(a) Find the amount owed at the end of 1 year.
(b) Find the amount owed at the end of 2 years.
The amount owed at the end of 1 year is $4120 and by the end of 2 years, $4243.60 when Tom borrows $4000 at an interest rate of 3% compounded each year.
What is compound interest?The interest you earn on interest is known as compound interest. Simple math can be used to demonstrate this: if you have $100 and it earns 5% interest annually, you will have $105 at the end of the first year. You will end up with $110.25 at the end of the second year. In order to calculate compound interest, multiply the principal of the original loan by the annual interest rate multiplied by the number of compound periods minus one.
Here,
principle amount=$4000
rate of interest=3%
For first year,
A=P(1+r/n)^(nt)
A=4000(1+3/12)^12*1
A=$4,120.00
For first year,
A=P(1+r/n)^(nt)
A=4120(1+3/12)^12*1
A=$4,243.60
When Tom borrows $4000 at an interest rate of 3% compounded annually, the total amount due at the end of one year is $4120, and at the end of two years, it is $4243.60.

7. In 2009, the national average price for milk was $3.11
and in 2011 it rose again to $3.57 per gallon.
Was the percent increase in cost greater from 2009
your answer.
The percentage increase in cost greater from 2009 is 14.79%
The average price of milk in 2009 = $3.11
The average of price of milk in 2011 = $3.57
The increase in price = The average of price of milk in 2011 - The average price of milk in 2009
Substitute the values in the equation
The increase in price = 3.57 - 3.11
= $0.46
The percentage increase = The increase in price / The average price of milk in 2009 × 100
Substitute the values in the equation
The percentage increase = ( 0.46 / 3.11 )×100
= 14.79%
Hence, the percentage increase in cost greater from 2009 is 14.79%

Inequality is referred to in mathematics when a relationship results in a non-equal comparison between two expressions or two numbers. In this instance, any of the inequality symbols, such as greater than symbol (>), less than symbol (), greater than or equal to symbol (), less than or equal to symbol (), or not equal to symbol (), is used in place of the equal sign "=" in the expression. Polynomial inequality, rational inequality, and absolute value inequality are the various types of inequalities that can exist in mathematics.
