Dada la siguiente información:

Tasa de interes anual (i)= 4,8%

Inversión inicial (VP)= $1.000.000

<u>Para calcular el valor final (VF), debemos usar la siguiente formula:</u>

VF= VP*(1 + i)^n

VF= 1.000.000*(1,048^5)

VF= $1.264.172,72

VF= 1.000.000*(1,048^18)

VF= $2.325.429,02

MATH HELP???

<h2>Answer:</h2>

The quadratic function are:

option: A A) y(y + 4) - y = 6

Option: C C.) 4b(b) = 0

<h2>Step-by-step explanation:</h2>

We know that the general equation of a quadratic equation in terms of a variable x is given by:

$ax^2+bx+c=0$

y(y + 4) - y = 6

On simplifying the terms we have:

$y^2+4y-y=6\\\\y^2+3y-6=0$

Hence, option: A is correct.

(3x + 2) + (6x - 1) = 0

$(3x + 2) + (6x - 1) = 0\\\\i.e.\\\\3x+2+6x-1=0\\\\i.e.\\\\3x+6x+2-1=0\\\\i.e.\\\\9x+1=0$

Hence, it is a linear equation.

Hence, option: B is incorrect.

4b(b) = 0

it could also be written as:

$4b^2=0$

Hence, it is a quadratic equation.

Hence, option: C is correct.

3a - 7 = 2(7a - 3)

$3a-7 = 2(7a-3)\\\\i.e.\\\\3a-7=14a-6\\\\\\i.e.\\\\14a-6-3a+7=0\\\\i.e.\\\\14a-3a-6+7=0\\\\i.e.\\\\11a+1=0$

which is again a linear equation.

Hence, option: D is incorrect.
