Michael invests USD 20 000 at 9.6% p.a. compounded monthly.
How long will it take for his investment to reach USD 25 000?
Given :
A = 25000
P = 20000
r % = 9.6 % = 0.096
n = 12
To Find :
The time taken say t.
Solution :
We know, compound interest is given by :
[tex]A=P(1+\dfrac{r}{n})^{n.t}[/tex]
Taking log both sides :
[tex]A=P(1+\dfrac{r}{n})^{n.t}\\\\log\ \dfrac{A}{P}= n.t\times log( 1+\dfrac{r}{n})\\\\t =\dfrac{1}{n}\times \dfrac{log\ \dfrac{A}{P}}{log(1+\dfrac{r}{n})}\\\\\\t=\dfrac{1}{12}\times \dfrac{log\ \dfrac{25000}{20000}}{log(1+\dfrac{0.096}{12})}\\\\\\t=2.33\ years[/tex]
Hence, this is the required solution.

Supongamos que tras una encuesta se ha concluido que si se elige al azar a una persona, la probabilidad de que esté a favor de la retransmisión de partidos de fútbol es de 0,8; de que esté a favor de la existencia de canales de televisión de pago, de 0,4;y de que esté a fa vor de la retransmisión de partidos de fútbol y tam bién de la existencia de canales de pago, de 0,3 a) Calcula la probabilidad de que una persona esté a favor de la retransmisión de partidos de fútbol o de la existencia de canales de televisión de pago.
Responder:
0,9
Explicación paso a paso:
Sea P (MuT) la probabilidad de que una persona esté a favor de retransmitir partidos de fútbol o la existencia de canales de televisión de pago
probabilidad de que esté a favor de retransmitir partidos de fútbol sea P (M) = 0,8
Probabilidad de que esté a favor de la existencia de canales de televisión de pago P (T) = 0,4
La probabilidad de que esté a favor de la retransmisión de partidos de fútbol y también de la existencia de canales de pago sea P (MnT) = 0,3
Usando la fórmula de notación de conjuntos
P (MuT) = P (T) + P (M) - P (MnT)
Sustituir los parámetros dados
P (MuT) = 0,4 + 0,8-0,3
P (MuT) = 1,2-0,3
P (MuT) = 0,9
De ahí que la probabilidad de que una persona esté a favor de retransmitir partidos de fútbol o la existencia de canales de televisión de pago es de 0,9.

1 mile divided by 2 laps =
There are 4 laps in one mile, therefore, "1 mile divided by 2 laps" = 2.
What is division?Division is the process of dividing a number by a given number.
Given, the statement "1 mile divided by 2 laps".
The statement written in mathematical form is:
(1 mile)/2 laps
There are 4 laps in one mile, therefore, substitute 1 mile = 4 laps into the above equation:
(4 laps)/2 laps

If has a decimal approximation of 3.4, then is between which two integers? In your final answer, include all calculations.
Answer: It is between 3 and 4.
Step-by-step explanation:
Integers are whole numbers and its opposite, for example, -5,-4,-3,-2,-1, 0, 1,2,3,4, 5 ,....
Meaning that 3.4 is not an integer so it fall between two integers and those integers has to be positive because 3.4 is a positive number.
3.4 is slightly greater than 3 but is less than 4.
Meaning that 3.4 is between the integers 3 and 4.

What is the slope and equation of a line parallel to the x-axis passing through (3,7)?
Answer:
We know that the equation is y=7 because it passes through point (3,7), and 7 is the y-coordinate of that point (remember we don't really care about the 3 because since the line is parallel to the x-axis, it will pass through all values of x, so the 3 is irrevalent).
Step-by-step explanation:
The equation of the line passing through the point (3,7) and parallel to the x-axis is y =7.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
We know that the equation is y=7 because it passes through the point (3,7), and 7 is the y-coordinate of that point (remember we don't really care about the 3 because since the line is parallel to the x-axis, it will pass through all values of x, so the 3 is prevalent.

how can you solve quadratic equation in one variable using factoring method?
The steps are;
look for two numbers such that if added will give the coefficient of x and if multiplied will give the product of the constant and the coefficient of x²Factor the common value from both brackets and get the required variableLet us assume the quadratic equation x² - 2x + 1 = 0
To solve this by factoring;
Step 1: We will first look for two numbers such that if added will give the coefficient of x and if multiplied will give the product of the constant andthe coefficient of x²
For the given equation, the two values are -1 and -1
The quadratic equation becomes;
x² - 1x - 1x + 1 = 0
x² - x - x + 1 = 0
(x²-x)-1(x-1) = 0
Step 2: Factorize the common value from both brackets
x(x-1)-1(x-1) = 0
x-1 = 0 and x - 1 = 0
x = 1twice
The given steps are the ways you can solve quadratic equations in one variable using factoring method
