Tema [17]

Answer:

Explanation:

Given that:

The abundance of three algal species in Lake A is now represented by the vectors:

[97, 84, 43] and [100, 80, 50]

Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:

a = [100 -97, 80 - 84. 50 - 43]

a = [3, -4, 7]

Thus, the magnitude of that change is:

|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}

|a| = \sqrt{9+16+49}

|a| = \sqrt{74}

|a| =8.6 \ mg/mL

The abundance of three algal species in Lake B is now represented by the vectors:

[25, 59, 22] and [20, 63, 15]

At Lake B, the change occurring in the vector of algae species can be determined as:

b = [20 -23, 63 - 59. 15 - 22]

b = [-3, -4, -7]

Thus, the magnitude of that change is:

|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}

|b| = \sqrt{9+16+49}

|b| = \sqrt{74}

|b| =8.6 \ mg/mL

Hence, for both Lake A and B, the magnitude of change is the same.
