Ascientist begins with 250 grams of a radioactive substance. after 250 minutes, the sample has decayed to 32 grams. rounding to five significant digits, write an exponential equation representing this situation. to the nearest minute, what is the half-life of this substance?

Part 1 :

Part 2 : Half life is 84 minutes ( approx )

Step-by-step explanation:

Part 1 : Suppose the function that shows the amount( in grams ) of the substance after t minutes,

If t = 0 min, A = 250 grams,

If t = 250, A = 32 grams,

Taking ln both sides,

Hence, the equation that shows this situation,

Part 2 : If A = 250/2 = 125,

Taking ln both sides,

Therefore, the half life of the substance would be 84 minutes.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
