Molly scupper wants to attend clarke university. she will need $90,000 6 years from today. assume molly's bank pays 6% interest compounded quarterly. what must molly deposit today to have $90,000 in six years? verify your answer.

This is similar to exponential growth problems...

F=Ir^t  F=final, I=initial, r=rate, t=time, 

The main difference here is that the annual rate is compounded quarterly so

90000=I(1+.06/4)^(4t)

90000=I(1.015)^(4t)  and since t=6 we have:

90000=I(1.015^24)

I=$62,958.95

verify...

F=62958.95(1.015^24)

F=$89999.996

F=$90000.00  rounded to nearest cent

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
