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

El ciclista recorre 18 kilómetros cada hora

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.

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)

The amount that Kathy got back after 4 years and 6 months is  $3945   .

In the question ,

it is given that ,

the amount invested by Kathy(P) = $3000

the rate at which the amount is invested (r) = 7% per annum

time for which the amount is invested (t) = 4 years and 6 month = 4.5 years

the simple interest calculated by

Simple Interest = ( 3000 × 7 × 4.5)/100

= 94500/100

= 945

So , the interest is $945 .

So , the amount that Kathy get = Principle + Interest

= 3000 + 945

= 3945

Therefore , amount that Kathy got back after 4 years and 6 months is  $3945   .

What is Linear Inequality?

The mathematical expression with unequal sides is known as an inequality in mathematics. 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.

The symbols "" and ">" signify tight inequalities, while "" and "" signify slack inequalities. A linear inequality looks precisely like a linear equation, but the symbol connecting two expressions is different.

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

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

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.

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.

4500 miles = 9 hours

The distance asteroid travel in 9 hours is 4500 miles

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.

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

The explicit equation for the table is,

f(n) = n² + 4

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

The equation for the nth term of the arithmetic sequence is  [tex]a_{n}[/tex] = 25 - 4n  

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

=>  [tex]a_{n}[/tex] = 25 - 4n
