g(5) means we substitute every x in the equation with a 5.

g(5) = (5)^2 - 4.

g(5) = 21.

Count the left handed and right handed spirals on the cacti in the photograph you should get two consecutive terms of the Fibona

lana [24]

You can count the spirals because they are coloured.

The left handed spirals are in red and you can count 13.

The rifht hanged spirals are in yellow and you can count 21.

Fibonacci sequence is: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... From 2 the next number is the sum of the two previous numbers:

2 = 1 + 1

3 = 2 + 1

5 = 3 + 2

8 = 5 + 3

13 = 8 + 5

21 = 13 + 8.

Fibonacci numbers are found in many structures in nature.

We have just found that these cacti enclose Fibonacci numbers 13 and 21.

Answer: 13 and 21

AABC has vertices at A(12, 8), B(4,8), and C(4, 14).

borishaifa [10]

Answer:

Triangle ABC and triangle MNO are congruent. A Rotation is a single rigid transformation that maps the two congruent triangles.

Step-by-step explanation:

ΔABC has vertices at A(12, 8), B(4,8), and C(4, 14).

length of AB = √[(12-4)² + (8-8)²] = 8

length of AC = √[(12-4)² + (8-14)²] = 10

length of CB = √[(4-4)² + (8-14)²] = 6

ΔMNO has vertices at M(4, 16), N(4,8), and O(-2,8).

length of MN = √[(4-4)² + (16-8)²] = 8

length of MO = √[(4+2)² + (16-8)²] = 10

length of NO = √[(4+2)² + (8-8)²] = 6

Therefore:

AB ≅ MN

AC ≅ MO

CB ≅ NO

and ΔABC ≅ ΔMNO by SSS postulate.

In the picture attached, both triangles are shown. It can be seen that counterclockwise rotation of ΔABC around vertex B would map ΔABC into the ΔMNO.
