The number y, decreased by 12
Answer:
tan C = 1/2
Step-by-step explanation:
The tan function in a right triangle is the opposite side over the adjacent side
tan C = 11/22
We can divide the top and bottom by 11
tan C = 1/2
Answer:
197.2 million
Step-by-step explanation:
The appropriate exponential equation for the population is ...
p(t) = 172.0e^(0.019t)
Then we can compute for t=7.2:
p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2
7.2 minutes from now, the population will be about 197.2 million.
___
For continuous growth (or continuous compounding), the exponential formula is ...
f(t) = (value at t=0)×e^(rt)
where r is the growth rate in one unit of time, and t is the number of time periods.
So you need to add 6n with +2 then 5-7
