A=20(1.25^t)

C=25+10t

A(4)=20(1.25^4)≈48.82≈49 alligators to nearest whole alligator

C(4)=25+10(4)=65 crocodiles.

Apply the Pythagorean Theorem to find the distance between points A and B.
irinina [24]

Answer:          

  Properties of a right tangle can be created in  a Coordinate Plane

  Distance between two points A and B are shown as below

Step-by-step explanation:

Find distance between two point using Pythagorean Theorem.

Properties of right triangles and creating right triangle as a coordinate Plane.

Suppose two point are drawn in triangle containing value of  (-2 , 4 ) and (-2, -2)

then

In (-2 , 4 ) and (-2,-2)

taking y-values that is  4 and -2

find difference between them such as

    4-(-2) = 6

Distance is (-2,4) is 6 unit from (-2,-2)

We can also find unit length of A and B

Side A:   (-1, 2) and (3,2)

      3-(-2)  = 5

side A is 5 unit in length

Side B : (-2,2) and (-2,-1)

      2 - (-1) = 3

Side B is 3 unit in length
