<em>Your answer would be: </em><u>A) 0</u>
Letters' B, C, and D are all greater than or equal -3 when they substitute "X".
Hope this helps you :)
<span>use the simple interest formula</span>
A. The scientific notation for 50,000,000 is 5 x 10^7 (to the 7th power)
B. After squaring 50,000,000 you'll get <span>2500000000000000. In </span>scientific notation, this is 2.5 x 10^15 (to the 15th power).
C. I think what it's asking is how I solved part B... this could be wrong, double check it. I solved it by multiplying 50,000,000 x 50,000,000 and then converting the product into scientific notation.
Hope this helps, if you have more questions, message me or comment under this post!
Answer:
5^11
Step-by-step explanation:
5^7/5^-7 is basically 5^7x5^7 which is 5^14. 5^14x5^-3 is 5^11.
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)
