Answer:

x =  − 6 ± √ 51

Step-by-step explanation:

The quadratic formula is x= -b ± √b^2-4ac / 2a. A is 1, b is 12, and c would be -15 if we subtract the 15 to the other side. Plugging the numbers in would be x= -12 ± √12^2-4(1)(-15) / 2(1) . x= -12± √144+60/ 2 --> x=-12± √204/2 --->               x= -6± √51

What principal invested at 8% compounded continuously for 4 years will yield $1190?
zhuklara [117]
For continuously compounded interest:

Amount = Principle * e^(rate * time)

A rate of 8% converted to a decimal value: r=0.08
With time t=4
and amount 1190

Plug all these values in,

1190 = Principle * e^(0.08 * 4)

And use your calculator to solve for the principle.
Maybe we'll call it P to make things easier.

1190 = P * e^(0.08 * 4)
1190 = P * 1.377

The principle is being multiplied by this 1.377,
divide by 1.377 to undo the multiplication.

864.11735 = P
