Answer:
f(86)-f(82)
Step-by-step explanation:
well f of 82 = 2 plus _ plus _ plus _ and f of 86 is 2+_+_+_ subtract them
(A) 3 (B) 4 (C) 47 (D) 59 (E) 83
these are some possible answers so the answer is b, 4
btw, 86-82 = 4 duh
Answer:
it’s b :)
Step-by-step explanation:
Answer:
x = 4y/3
Step-by-step explanation:
y = 3x/4
Multiply both sides by 4.
4y = 3x
Divide both sides by 3.
x = 4y/3
This is the concept of differential equations, given that
dp/dt=rp
then:
dp/p=rdt
thus:
ln p=rt+C
p=e^(rt+C)
P=Ke^(rt)
when t=210 days=7 months, p=2k
2k=k×e^(7r)
2=e^(7r)
ln2=7r
r=ln(2)/7
r=0.0990
