Answer:
x=((log(81))/(log(3))+2)/3
Step-by-step explanation:
so what you want to do is get 3x-2 out of the exponent
you can do that by using log
so apply log to both sides and you get
log(81)=(3x-2)log(3)
the 3x-2 is moved in front of the log due to a log rule
then (log(81))/(log(3))=3x-2
(log(81))/(log(3))+2=3x
((log(81))/(log(3))+2)/3=x
then use a calculator to find the exact value
hope this helps im sorry my explanation is a bit confusing, ask any questions you have
Answer:
See below for answers
Step-by-step explanation:
(a) Substitute t=2015 into the function:
p(t) = 1.32t - 2589.6
p(2015) = 1.32(2015) - 2589.6
p(2015) = 2659.8 - 2589.6
p(2015) = 70.2
So, there will be 70,200 people in 2015 who will be 100 years or older.
Substitute t=2025 into the function:
p(t) = 1.32t - 2589.6
p(2025) = 1.32(2025) - 2589.6
p(2025) = 2673 - 2589.6
p(2025) = 83.4
So, there will be 83,400 people in 2025 who will be 100 years or older.
(b) Substitute p(t)=100 into the function and solve for t:
p(t) = 1.32t - 2589.6
100 = 1.32t - 2589.6
2689.6 = 1.32t
2037.57 = t
2038 = t
Therefore, the number of people 100 years or older will reach 100,000 by 2038.
