Answer:
521.183133274
Step-by-step explanation:
−3y−(8y+1)
Distribute the Negative Sign:
=−3y+−1(8y+1)
=−3y+−1(8y)+(−1)(1)
=−3y+−8y+−1
Combine Like Terms:
=−3y+−8y+−1
=(−3y+−8y)+(−1)
=−11y+−1
Answer:
117
Step-by-step explanation:
If you were looking for the greatest common factor, you'd want to see the list of their factors.
A prime factorization breaks it down as far as possible and as a result has as few high numbers as possible. If you want the number to be as great as possible, you would want to see the list of all the factors.
P = ce^(kt)
make p = 2c because doubling will be
like c-->2c, so if p = 2c, then
p = ce^(kt)
2c = ce^(kt)
2c/c = (ce^(kt))/c
2 = e^(kt)
Now take natural logarithm (ln) of both sides of the equation:
ln (2) = ln (e^(kt))
0.693 = kt×ln e
**this is because ln of an exponent makes the exponent become multiplied by the ln,
and ln e = 1
0.693 = kt×ln e
0.693 = kt×1, and t = 11 years
0.693 = k(11)
0.693/11 = 11k/11
k = 0.063, multiply by 100 to get %
k = 6.3%
answer is C
