Answer:
Step-by-step explanation:
This is definitely exponential growth. The ruling formula will have the form
y = c·(2)^(nx), where the "2" comes from "double," c is the initial value and n is the growth constant.
63 = 0.63×10² = 126/2 = 3×21 = √3969 = 77₈
The last is as a base-8 number.
Answer:
Step-by-step explanation:
Let H and P represent the number of history and physics textbooks.
We are told that:
1) H + P = 236/week, and
2) H = 3P [A disgrace, but that's a different problem]
We can substitute the definition of H in the second equation into the first:
H + P = 236/week
3P + P = 236/week
4P = 236
P = 59
H = 3P, so H = 3*(59) or 177
59 Physics and 177 History books for a total of 236 books sold that week.
All you have to do is add it could be so simple 8$ + $2 + $2400
