It’s 42 but Carrier the 2
Answer: The answer is 81.
Answer:
dA/dt = k1(M-A) - k2(A)
Step-by-step explanation:
If M denote the total amount of the subject and A is the amount memorized, the amount that is left to be memorized is (M-A)
Then, we can write the sentence "the rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized" as:
Rate Memorized = k1(M-A)
Where k1 is the constant of proportionality for the rate at which material is memorized.
At the same way, we can write the sentence: "the rate at which material is forgotten is proportional to the amount memorized" as:
Rate forgotten = k2(A)
Where k2 is the constant of proportionality for the rate at which material is forgotten.
Finally, the differential equation for the amount A(t) is equal to:
dA/dt = Rate Memorized - Rate Forgotten
dA/dt = k1(M-A) - k2(A)
Answer:
it's 24.5 Sq feet
Step-by-step explanation:
if you multiply 7 × 3.5 you get the awnser
Jon=x-2 jor=x
2(x-2)=x+6
2x-4=x+6
combine like terms
x=10 Jordan's age
x-2 or 10-2 =8 Jonathan's age
13-10= 3 years apart
when aylon was 3 Karina was 6
2×3 =6
this was 7 years ago(answer)
10-3=7
13-6=7
48-36=12 years apart
when kd was 6 and md 18
3×6=18
30 years ago
36-6=30
48-18=30
