An 80-foot rope is attached to a boat 7 feet above the water level and a boy jumps over the wake while wakeboarding. What is the distance between his hands and the water level ?

2.81 feet.

Step-by-step explanation:

Please find the attachment.

We have been given that an 80-foot rope is attached to a boat 7 feet above the water level and a boy jumps over the wake while wake-boarding. We are asked to find the distance between boy's hands and the water level.

Let h represent opposite side of right triangle.

We can see that rope forms a right triangle with boat and water level, where 80 feet is hypotenuse of triangle to 87 degree angle.

The distance between boy's hands and the water level would be 7 feet minus the opposite side of right triangle.

We know that cosine relates the adjacent side of right triangle with hypotenuse.

Therefore, the distance between boy's hands and the water level is approximately 2.81 feet.

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 !
