There are 2 solutions to this equation

$x=-\frac{1}{4} +i\frac{\sqrt{19} }{4} ,x=-\frac{1}{4} -\frac{\sqrt{19} }{4}$

Step-by-step explanation:

for a quadratic equation of the form ax^2 + bx + c = 0 the solutions are

$x_{1,2}=\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

$x=\frac{-2+\sqrt{2^{2}-4.4.5 } }{2.4} :-\frac{1}{4}+ i\frac{\sqrt{19} }{4} \\x=\frac{-2-\sqrt{2^{2}-4.4.5 } }{2.4} :-\frac{1}{4} -i\frac{\sqrt{19} }{4}$

Find the amount of money in savings account if $3200 was deposited for 3 years at 40% interest compounded annually. Find the int

a_sh-v [17]

Step-by-step explanation:

Formula for compound interest is given by

$A = P(1 + R) ^{n}$

Where

A is the amount at the end of the period

P is the principal

R is the rate

n is the period

The interest = A - P

From the question

P = $ 3200

n = 3 years

R = 40%

So we have

$A = 3200 \times 2.744$

A = $ 8780.80

<h3>The amount is $ 8780.80</h3>

The interest is

$ 8780.80 - $3200

Hope this helps you
