I don’t know but I’m learning negative numbers maybe -3
Answer:
Step-by-step explanation:
Y is every x + 1, so for the first thingy magnify, it would had been -2+1 which is -1
---<span>
y(t) = a*e^(kt)</span><span>
---
now:</span><span>
130 mg</span><span>
---
one hour from intake:</span><span>
130 * (1 - 0.11) = 115.7 mg</span><span>
---
y(1) = 115.7 = 130*e^(k(1))</span><span>
115.7 = 130*e^k</span><span>
115.7/130 = e^k</span><span>
ln( 115.7/130 ) = ln( e^k )</span><span>
ln( 115.7/130 ) = k</span><span>
k = -0.1165338
</span><span>---
three hours from intake:</span><span>
y(3) = 130*e^(3k)</span><span>
y(3) = 91.64597</span><span>
---
answer:</span><span>
three hours after drinking a cup of coffee, 91.6 mg of caffeine will remain in the body
</span>
18.641 Miles is your answer
