Answer:
Step-by-step explanation:
given that a bacteria culture initially contains cells and grows at a rate proportional to its size.
If P be the size then growth rate
where k is constant of proportionality
separate the variables as
If after 1 hour population is B (say)
then k = ln B - ln A
Using this
P(t) =
b) P(e) =
c) Rate of growth =
Unless you give B value, d cannot be solved
Answer:
<em>The actual distance between Rose Lake and the hiking trail is 7 miles.</em>
Step-by-step explanation:
The actual distance between Rose Lake and the main road is 3.5 miles and the scaled distance on the map is 2 inch.
Suppose, the actual distance between Rose Lake and the hiking trail is miles.
Given that, the scaled distance from Rose Lake to the hiking trail on the map is 4 inch.
So, <u>according to the ratio of "scaled distance" to the "actual distance"</u>, the equation will be......
Thus, the actual distance between Rose Lake and the hiking trail is 7 miles.
