You want to have $15,000 in 11 years. You will invest how much into an account that has an annual rate of 4.4% compounded daily?

igor_vitrenko [27]

Given:

Future Value = $15,000

time (t) = 11 years

rate (r) = 4.4% or 0.044

number of conversions per year (m) = 365

Find: Initial amount or the Principal

Solution:

Formula for Compound Interest is:

$F=P(1+\frac{r}{m})^{mt}$

From that, we can derive the formula for the Principal or the initial amount.

$P=\frac{F}{(1+\frac{r}{m})^{mt}}$

Let's plug in the given data above to the formula of the principal value.

$P=\frac{15,000}{(1+\frac{0.044}{365})^{365\times11}}$

Then, solve for P.

$P=\frac{15,000}{(1.000120548)^{4015}}=\frac{15,000}{1.622504316}\approx9,244.97$

Answer: You must invest $9, 244.97 to the account in order to get $15,000 after 11 years.

#19 how do you do the work???!

Semenov [28]

Answer:

$x=\frac{1}{3}$

Step-by-step explanation:

move the terms with $x$ to the left side of the equation:

add 3x to both sides

$3x-1+3x=1$

add 3x and 3x

$6x-1=1$

move all term not containing $x$ to the right side:

add 1 to both sides of the equation

$6x=1+1$

$6x=2$

divide each term by 6

$\frac{6x}{6}=\frac{2}{6}$

$x=\frac{2}{6}$

simplify the fraction

$x=\frac{1}{3}$

Factorise x cubed - x

kirill [66]

Answer:

= x(x+1)(x-1)

Step-by-step explanation:

Given the expression x³ - x

On factorizing

x³ - x

= x(x²-1)

Using difference of two square

a² - b² = (a+b) (a-b)

x² - 1

= x² - 1²

= (x+1)(x-1)

The complete factor

x³ - x

= x(x²-1)

= x(x+1)(x-1)
