Compound interest of $1000 is invested at 10% compounded continuously, the future value s at any time t in years is given by s=1
crimeas [40]

Answer: 6.93 years

Step-by-step explanation:

Given

Rate of interest is r=10\%

Future value is given by s=1000e^{0.1t}

For the investment to double itself, i.e. s=2000

\Rightarrow 2000=1000e^{0.1t}\\\Rightarrow 2=e^{0.1t}\\\\\text{Taking log both sides}\\\\\Rightarrow \ln 2=0.1t\\\\\Rightarrow t=\dfrac{\ln 2}{0.1}\\\\\Rightarrow t=6.93\ \text{years}

It takes around 6.93 years to double the investment.

If CD=18, find the value of EB.
aliina [53]

Step-by-step explanation:

Chord AB and Chord CD are equidistant from the center of the circle.

\therefore \: chord \: AB \cong chord \:  CD \\  \\  \therefore \:  \frac{1}{2} \:  \: AB \cong \frac{1}{2} \: \:  CD  \\  \\ \therefore \: EB = \frac{1}{2} \:  \times 18\\  \\  \huge \purple{ \boxed{\therefore \: EB =9}}
