if $4000 is invested in an account that pays interest compounded continuously, how long will it take to grow to $8000 at 7%?
Archy [21]

So, since it is continuously, we need to think of PERT


A=P\times e^{rt}

So, we just plug our numbers in to solve for T

8000=4000e^{.07t}\\\ln(8000)=\ln(4000e^{.07t})\\\ln(8000) = \ln(4000) + \ln(e^{.07t})\\\ln(8000)=\ln(4000)+.07t\ln(e)\\\ln(8000)=\ln(4000)+.07t\\\frac{\ln(8000)}{\ln(4000)}=.07t\\\frac{\ln(8000)}{.07\ln(4000)}=t\\ 15.479=t

It will take 15.479 years

For the following right triangle, find the side length X. round to nearest hundredth
Wewaii [24]
For this problem, you will need to use the pythagorean theorem which is a^{2} +  b^{2} =  c^{2} 
So a and b are usually the sides that are NOT the hypotenuse, or in this case the long side that is not at a 90 degree angle.
You will start by plugging 12 into with (a) or (b) but not both. And then you will plug 17 in for (c). Make sure you square these values to solve the equation. Once you do that, it is basic algebra from there to solve for the missing variable. If you want to check to see if your answer is correct, then plug all the side numbers back into the equation. Also your answer should be between 12 and 17, or possibly one of those numbers.
