When we have a 75% of the wound healed, we have the following area:
area of the wound=(100%-75%) (initial area) =25% (initial area)
In this case:
area of the wound=25%(80 cm²)=20 cm²
A(t)=80(10^-0.023t)
If A(t)=20
Then:
20=80(10^-0.023t)
10^-0.023t=20/80
10^-0.023t=0.25
log (10^-0.023t)=log 0.25
-0.023t log 10=log0.25 log 10=1
-0.023t=log0.25
t=log 0.25 /-0.023
t=26.176≈26
The wound be healed (75%) in 26 days
I suppose it made the free states and slave states in some way even. When Missouri became a slave state they kept the north end of the Louisiana purchase free stated and banned slavery there.
Not sure but hope what I know help a little...Slavery was “an unqualified evil to the negro, the white man, and the State,” said Abraham Lincoln in the 1850s. Yet in his first inaugural address, Lincoln declared that he had “no purpose, directly or indirectly, to interfere with slavery in the States where it exists.” He reiterated this pledge in his first message to Congress on July 4, 1861, when the Civil War was three months old.<span>Did You Know?When it took effect in January 1863, the Emancipation Proclamation freed 3.1 million of the nation's 4 million slaves.</span>
What explains this apparent inconsistency in Lincoln’s statements? And how did he get from his pledge not to interfere with slavery to a decision a year later to issue an emancipation proclamation? The answers lie in the Constitution and in the course of the Civil War. As an individual, Lincoln hated slavery. As a Republican, he wished to exclude it from the territories as the first step to putting the institution “in the course of ultimate extinction.”
