Birth amd death rates of animal populations are typically not constant, they vary periodically with the passage of the season. Find P(t) if P satisfies the differential equation

dP/dt=(2+9cos(2pit))P

where t is in years and there is an intial population C

P(t)=?

Ive seen this before! the answer is b

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to

8-2x+3x2=6 and six is your answer
