Leto [7]

Answer:

There will be 9897.47€ in the account.

La cantidad será de 9897.47€.

Step-by-step explanation:

Future value with annuity:

The future value formula, for an annuity, is:

FV = \frac{P((1+r)^{n} - 1)}{r}

An annuity means that a number of payments happen during the period(an year, for example.

P is the value of the deposit, r is the interest rate, as a decimal, and n is the number of deposits.

In this question:

1000 € each year, so P = 1000

Interest rate of 6%, so r = 0.06

One application per year for 8 years, so n = 8

Total amount:

FV = \frac{1000((1+0.06)^{8} - 1)}{0.06} = 9897.47

There will be 9897.47€ in the account.

La cantidad será de 9897.47€.

Solve by factoring and list only the positive solution: 2x2 - 5x = 88
Semmy [17]
It has to be noted that there are several ways to factor the item. One of these is shown below. 

The general form of a quadratic equation is,
            Ax² + Bx + C = 0

where A and B are numerical coefficients and C is the constant. If we are to express the given equation in this form, 
        2x² - 5x - 88 = 0

The sum of the roots, x₁ and x₂ is -B/A and the product is equal to C/A.

Sum: x₁ + x₂ = -(-5/2) = 5/2
 Product: x₁x₂ = -88/2 = -44

The values of x₁ and x₂ are 8 and -11/2.

The factors are (x - 8) and (x + 11/2)

<em>ANSWERS: 8 and -11/2. </em>
