No solution for the quadratic equation because of the √-20
L am sure this is a answer of this question
Answer:
4 Minutes = 240 seconds = 6*40 seconds
30*(1/2)^6 = 30*1/64 = 30/64 = 15/32 = 0.5
4 minutes later there is approx. 0 to 1 bacteria alive.
Evaluate<span> the series by expanding the summation, then adding all of the values. 154 would be the answer.</span>
2x=84 is a one step equation so all u need to do is divided both sides by 2 so the variable can be by itself, so x=42
