Dale has $2,000 to invest. He has a goal to have $4,200 in this investment in 12 years. At what annual rate compounded continuou

max2010maxim [7]

Answer:

Dale would reach his goal with an annual interest rate of 6.18%.

Step-by-step explanation:

For compounding continuously, recall the following equation:

$A = P(e)^{rt}$

A = final amount ($4200)

P = principal amount ($2000)

r = rate (unknown)

t = time (12 years).

You'll have to use natural logs for these types of questions. Remember that ln (e) = 1.

8) Solve using the Quadratic Formula. x2 + 3x - 5 = 0

maks197457 [2]

Step-by-step explanation:

$x^{2} + 3x - 5$

For any quadratic equation $ax^{2} + bx + c = 0$ , the quadratic formula is as follows:

$\frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}$

From the given quadratic equation, we know that $a = 1$ , $b = 3$ and $c = -5$ . Plugging in these values into the quadratic formula gives us the following:

$\frac{-(-3) \pm \sqrt{(3)^{2} - 4(1)(-5)}}{2(1)}$

$\frac{3 \pm \sqrt{9 + 20}}{2}$

$\frac{3 \pm \sqrt{29}}{2}$
