Help please- Annuities - Find Time of Investment Algebra Two

suter [353]

Based on the calculation below, the number of years it would be for Mia to have $34,000 is 29.1 years.

<h3>How do we find the period or time of investment?</h3>

The formula in the question is the formula for calculating the future value of an ordinary annuity and it can be rewritten as follows:

A = d((((1 + i)^n) – 1) / i) …………………………… (1)

Where:

A = $34,000

d = $850

i = 0.4% * number of months in a year = 0.4% * 12 = 4.8% = 0.048

n = number of years?

Substitute all the values into equation (1) and solve for n, we have:

$34,000 = $850((((1 + 0.048)^n) - 1) / 0.048)

$34,000 / $850 = (((1 + 0.048)^n) - 1) / 0.048

40 = (((1 + 0.048)^n) - 1) / 0.048

40 * 0.048 = ((1 + 0.048)^n) – 1

1.92 + 2 = (1 + 0.048)^n

3.92 = 1.048^n

Taking the log of both sides, we have:

Log3.92 = nlog1.048

0.593286067020457 = n 0.0203612826477079

n = 0.593286067020457 / 0.0203612826477079

n = 29.1379515370189

Rounding to the nearest of a year, we have:

n = 29.1

What are the zeros of the polynomial function

solniwko [45]

Option B

The zeros of the polynomial function are x = 0 , x = 6, x = -1

Solution:

Given function is:

$f(x) = x^3 -5x^2 - 6x$

To find: zeros of the polynomial function

To find the zeros of polynomial function, set the function equal to zero and then solve for x.

$x^3 -5x^2 - 6x = 0$

Taking "x" as common term, we get

$x(x^2 - 5x - 6) = 0$

Equating to zero,

$x = 0 \text{ and } x^2 - 5x - 6 = 0$

So one of the zeros of polynomial is x = 0

Let us solve $x^2 - 5x - 6 = 0$ to find other zeros

Let us solve using quadratic formula,

$\text {For a quadratic equation } a x^{2}+b x+c=0, \text { where } a \neq 0\\\\x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Using the above formula,

$\text{ for } x^2 - 5x - 6 = 0 \text{ we have } a = 1 ; b = -5 ; c = -6$

$\text{ The discriminant } b^2 - 4ac > 0 , \text{ so, there are two real roots }$

Substituting the values of a, b, c in above formula,

$x=\frac{-(-5) \pm \sqrt{(-5)^{2}-4(1)(-6)}}{2(1)}\\\\x=\frac{5 \pm \sqrt{25+24}}{2}=\frac{5 \pm \sqrt{49}}{2}\\\\x=\frac{5 \pm 7}{2}\\\\x=\frac{5+7}{2} \text{ or } x=\frac{5-7}{2}\\\\x=\frac{12}{2} \text{ or } x=\frac{-2}{2}\\\\x=6 \text{ or } x=-1$

Thus the zeros of the polynomial function are x = 0 , x = 6, x = -1
