If $360 is invested at an interest rate of 13% per year and is compounded continuously, how much will the investment be worth in 3 years? use the continuous compound interest formula: a= pe^rt
a) $584.88
b) $583.66
c) $581.27
d) $268.11

  none of the above; $531.71

Step-by-step explanation:

Fill in the given numbers and do the arithmetic.

  A = $360·e^(0.13·3) = $360·e^0.39 ≈ $360·1.1.47698

  A ≈ $531.71

___

None of the offered choices is correct. Have your teacher show you how this problem is worked.

_____

Answer choice c) is approximately correct for an interest rate of 16%. The correct value would be $581.79.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
