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.

Which point on the graph is a direct variation equation in which k=12.4

frez [133]

Answer:

The correct answer would be A) (4, 49.6)

Step-by-step explanation:

In order to find the equation, we first have to start with the base form of direct variation.

y = kx

Now we input the k value.

y = 12.4x

Now that we have this, we can try the ordered pairs and look for which satisfies the equation.

y = 12.4x

49.4 = 12.4(4)

49.4 = 49.4

Since this is the true statement, this is the ordered pair that works.

5. Factor x²-x-72 (x-8)(x+9) (x-6)(x+12) (x+6)(x-12) (x+8)(x-9)

Artyom0805 [142]

Answer:

(x + 8)(x - 9)

Step-by-step explanation:

(x+8)(x-9)

= x² - 9x + 8x - 72

= x² - x - 72

Then

The factorization of x² - x - 72 is (x+8)(x-9)

The rectangle below has an area of 144x^4144x 4 144, x, start superscript, 4, end superscript square meters and a width of 12x12

loris [4]

By definition, the area of a rectangle is given by:
A = (w) * (l)
Where,
w: width
l: length
Substituting values we have:
144x ^ 4 = (12x) * (l)
Clearing the length we have:
l = (144x ^ 4) / (12x)
l = 12x ^ 3
Answer:
the length of the rectangle is:
l = 12x ^ 3
