La desintegración de una sustancia radiactiva, XJ44, se ajusta al modelo matemático de la imagen. Donde po es la cantidad inicial de sustancia; p es la cantidad final de sustancia; y t, el tiempo transcurrido en años. Se define el tiempo medio de un productor como el tiempo necesario para que se desintegre la mitad de la sustancia de la que se dispone. Calcula el tiempo de vida medio de la sustancia XJ44.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

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 !

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
