bezimeni [28]

You would do:


t = time in years


14,800 = 10,000(1+0.08/4)^4t


1.48 = 1.02^4t


log_1.02(1.48) / 4 = t


((log 1.48)/ (log 1.02))/4 = t


t ~ 4,949 years

How do you round 7,298,341 to the nearest 10,000.
Cloud [144]
You would have to underline 9 since that is the 10,000 place and draw an arrow from the 9 to the 8 next to it and if it is 5 or more you would have to add 1 to the 9 if it is 4 or less you would change the whole number into 7,290,000. If it is 5 or more the 9 would become a 10 which would make the number 7,300,000
