$8000 principal earning 5% compounded annually, after 6 years

Verdich [7]

Future amount after 6 years will be: $10720.76

Step-by-step explanation:

Principal = $8000

Interest= 5% compounded annually

Time = 6 years

We need to find A (future amount)

The formula used is:

$A=P(1+\frac{r}{n})^{nt}$

A= Future amount

P= Principal amount

r= interest rate

n= no of times interest is applied

t= time

Putting values and finding A

P=8000. r=0.05, n=1, t=6

$A=P(1+\frac{r}{n})^{nt}\\A=8000(1+\frac{0.05}{1})^{1*6}\\ A=8000(1+0.05)^{6}\\ A=8000(1.05)^{6}\\A=10720.76$

So, Future amount after 6 years will be: $10720.76

Use the quadratic formula to solve the equation 2x^2+2x-4=0

const2013 [10]

Answer:

Step-by-step explanation:

The quadratic formula for the quadratic equation ax² + bx + c = 0:

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$2x^2+2x-4=0\qquad\text{divide both sides by 2}\\\\x^2+x-2=0$

$a=1,\ b=1,\ c=-2$

Substitute:

$x=\dfrac{-1\pm\sqrt{1^2-4(1)(-2)}}{2(1)}=\dfrac{-1\pm\sqrt{9}}{2}=\dfrac{-1\pm3}{2}\\\\x_1=\dfrac{-1-3}{2}=\dfrac{-4}{2}=-2\\\\x_2=\dfrac{-1+3}{2}=\dfrac{2}{2}=1$
