Answer:
Step-by-step explanation:
A bacteria culture initially contains 100 cells and grows at a rate proportional to its size.
Formula for the exponential growth is
where A0 is the initial cells (100) and t is the number of hours
After an hour the population has increased to 380
when t=1 the value of A is 380
Take ln on both sides
r=1.33500
Answer:
x=5
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
4x−3−2x=2x+7−2x
2x−3=7
Step 2: Add 3 to both sides.
2x−3+3=7+3
2x=10
Step 3: Divide both sides by 2.
x=5
And theres our answer.
