Double
from initial amont of P to final amount of 2P
so
2P=P(1.071)^time
divide both sides by P
2=1.071^time
take the ln of both sides
ln2=timeln1.071
divide both sides by ln 1.071
(ln2)/(ln1.071)=time needed
using calculator
10.1052=time needed
about 10.1 hours
Answer:
k-d
Step-by-step explanation:
if y is one point and k is another but d is in the middle, to find y i would assume you would just subtract d from k so k-d=y
Answer:
500
Step-by-step explanation:
189 is 45% of 420 and 198 is 55% of 360
189 = .45x
/.45 /.45
420 = x
198 = .55x
/.55 /.55
360 = x
