B = 3.
Plug it in to get -7 + 1 = -6
Answer:
Step-by-step explanation:
it is exponential decay
f(x)=a(1/2)^x
where a is the original volume and x is the time in minutes.
The answer is a. 5 x 10³.
3.75 x 10^5 = 375,00.( population of Greenville)
375,000 ÷ 75 = 5,000 ( population of Fairview)
5 x 10³(1,000)= 5,000.
Area(S) = y×h
h = 10, area(S) = 160 mi²
160 = y×10
y = 16 mi
Answer: y = 16 mi
