Answer:
db / dt = kb
this becomes b(t) = Ce^(kt)
C = 100, the initial population
P(1) = 420 = 100 e^(1k)
4.2 = e^k
ln 4.2 = k
a) thus, b(t) = 100 e^(t ln 4.2)
b) b(3) = 100 e^(3 ln 4.2)
c) growth constant will still be ln 4.2 (constant percentage of populatioin)
d) 10000 = 100 e^(t ln 4.2)
100 = e^(t ln 4.2)
ln 100 = t ln 4.2
t = ln 100 / ln 4.2

Rotation
It’s rotating 90 degrees counterclockwise
Answer:
3 pounds
Step-by-step explanation:
12/4=3 (because we need to see how much bryant ate first)
12-3=9 (original - what bryant ate)
9/3=3 (what was left after bryant finish and what 1/3 of 9 is)
