Answer:
all follow the sequence
Step-by-step explanation:
Pinecone and Pineapple - Scales and bracts are modified leaves, and the spiral arrangements in pine cones and pineapples reflect the spiral growth habit of stems. To confirm this, bring in a leafless stem from some tree or shrub and look at its buds, where leaves were attached.
Artichoke - The spiral of an artichokes leaves can be described by the Fibonacci Sequence. This sequence is a simple mathematical pattern where each successive number in the sequence is equal to the sum of the two preceding numbers, beginning with 0 and 1.
Nautilus shell - Each number is the sum of the two previous numbers. An approximation of a logarithmic spiral, created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling; this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34.
Answer:
What are the options?
Step-by-step explanation:
Answer:
Length = 50 units
width = 35 units
Step-by-step explanation:
Let A, B, C and D be the corner of the pools.
Given:
The points of the corners are.




We need to find the dimension of the pools.
Solution:
Using distance formula of the two points.
----------(1)
For point AB
Substitute points A(30, 25) and B(30, 25) in above equation.



AB = 50 units
Similarly for point BC
Substitute points B(-20, 25) and C(30, -10) in equation 1.



BC = 35 units
Similarly for point DC
Substitute points D(-20, -10) and C(30, -10) in equation 1.




DC = 50 units
Similarly for segment AD
Substitute points A(-20, 25) and D(-20, -10) in equation 1.




AD = 35 units
Therefore, the dimension of the rectangular swimming pool are.
Length = 50 units
width = 35 units
