Tanya runs a catering business. based on her records, her weekly profit can be approximated by the function latex: f\left(x\right)=2x^2-44x-150 f ( x ) = 2 x 2 − 44 x − 150 , where latex: x x is the number of meals she caters. if latex: f(x) f ( x ) is negative, it means that the business has lost money. what is the number of meals that tanya needs to cater in order to break-even?

The function

is a parabola concave up, whose solutions are

from here, you can use the quadratic formula

to find that the solutions of the parabola are

So, the parabola is positive if (which wouldn't make sense in our case) or

So, if Tanya caters 25 meals she breaks even, and starting with the 26th meal she will begin to profit.

step-by-step explanation:

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 !
