Shakaro Richardson English 120 Professor Coombes How to perform the ancient art of origami Origami is the ancient art of paper-folding that is believed to originate from Japan. It has made its way across to the western territories‚ and has commercial uses. What makes origami so special though? Does it even help with anything? Performing origami improves hand-eye-coordination‚ creates toys for kids‚ and provides cultural awareness. That a triple threat and it can do so much more than that

Absolute values In an absolute value‚ everything with it is counted as a positive. ∣-a∣ = --a= a ∣a∣ =a In an equation‚ absolute values have two possibilities when talking about equations ∣a+b∣ =x = a+b=x = a+b= -x e.g. Solve ∣x-4∣=8 x-4=8 OR x-4= -8 x=12 x=-4 Sub both answer into the equation ∣12-4∣ =8 OR ∣-4-4∣ =8 8=8 8=8 Both solution re true so x=12 or x=-4 Absolute inequalities (method 1) If ∣a+b∣ ≤x∣a+b∣

The Five Platonic Solids The five platonic solids are the tetrahedron‚ cube‚ octahedron‚ dodecahedron‚ and a icosahedron. They are named for the greek philosopher Plato. Plato wrote about them in the Timaeus (c.360 B.C.) in which he paired each of the four classical elements earth‚ air‚ water‚ and fire with a regular solid. Earth was paired with the cube‚ air with the octahedron‚ water with the icosahedron‚ and fire with the tetrahedron. The fifth Platonic solid‚ the dodecahedron‚ Plato says that

Maxima and Minima First Derivative Test 1) We are given the function First‚ we find the derivative: We set the derivative equal to 0 and solve: Since the domain of f is the same as the domain of f’‚ 4 is the only critical number of f. Testing: x < 4 | f’(0) = -8 | f is decreasing | x > 4 | f’(5) = 2 | f is increasing | By the First Derivative Test‚ x = 4 is a local minimum. 2) We are given the function First‚ we find the derivative: We set the derivative

Lab: Momentum Conservation Abstract This experiment aims to test the law of conservation of momentum by using cart and track system. Procedure 1. Put two carts onto the track. 2. Hit the button on the cart so that they start to move at opposite directions. 3. Find the position where the carts hit the end at the same time. 4. Find the distance that each cart traveled. 5. Repeat step 1-4 with 500g and 1000g weights on one of the carts. Data and Calculation m1m2=x2x1

Diophantus was a Greek mathematician that lived in Alexandria in the 3rd Century. His estimated birth and passing years are said to be from 150 B.C. to 350 A.D. Although there is not enough information about his life‚ there is a riddle that estimates how long he lived. The mathematic puzzle is known as ‘Diophantus Riddle’. The riddle states he married while he was 33‚ then he had a son who lived for 42 years and the total years Diophantus lived according to the riddle was a total of 84 years. Through
