Answer:
.6
Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
Note that when you multiply two negative numbers, the answer will result as a positive number. Also note that when you multiply a negative number with a positive number, then your answer will result in a negative number.
(-1)(-1) = 1
(1)(-3) = -3
-3 is your answer.

Answer:
88%
Step-by-step explanation:
Move the decimal two times to the right and add a percent sign.
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
