Express log6(19) in terms of common logarithms. Then approximate its value to four decimal places.
Answer:
log19/log6=1.6433
In a certain area, the sale price of new singlefamily homes has increased 4.1% per year since 1992. If a house was purchased in this area in 1992 for $75,000 and the growth continues, what will be the sale price in 2006? Use y=a(1+r)^t and round to the nearest cent.
Answer:
y=75,000(1+0.041)^14
y=75,000(1.041)^14
y=75,000(1.755)
y=$131625.00
Thanks

I suppose, but given all the rest of the problems I bet you were supposed to do
14 log (1.041)
and then take the anti log instead of using the y^x key
