A submarine travels 7 km due East from its base and then turns and travels due North for 12.5 How far away is the submarine from its base?
Give your answer rounded to 1 DP.

The submarine is 10.4 km far from its base.

Step-by-step explanation:

Given that:

Distance traveled east = 7km

Distance traveled north = 12.5 km

This is will form a right triangle, where the distance from east to north is hypotenuse.

Here,

a = 7 , b = x and c = 12.5

Using Pythagorean theorem,

Taking square root on both sides

Hence,

The submarine is 10.4 km far from its base.

the y will be in still but your answer will be y x 3

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
