\left(1+\frac{0.035}{365}\right)^{365}-1

you'll get a decimal format, just multiply it times 100, to get the % format

A = P.e^(r.t)
P=1000
e = 2.71828
t=1 (one year)

A = 1000(e)³⁵/¹⁰⁰⁰

A = 1000(2.71828)³⁵/¹⁰⁰⁰ = 1035.62

Monday<br> What time is 5 3/4 hours after<br> 11:32 pm?
Marina86 [1]

bearing in mind that the an hour has 15 + 15 + 15 + 15 = 60 minutes, so 15 minutes in 1/4 of an hour, thus 45 minutes is 3/4 of an hour.

now, from 11PM, if we add the 5 hours first, we'll be at 4AM, pass midnight of course.

now let's add the minutes, 32 and then 45, that gives us 77 minutes.

so the time will be 4AM plus 77 minutes, since 60 minutes is 1 hr, so 4AM plus 1 hr and 17 minutes, that'd be 5:17AM.
