He ran down the street of the suburbs. His eyes reflected the colour of the far away ocean. At that moment, the rusty door closed over the Erdrich chapel of my heart. As I watched him approach, my dreams and aspirations were nailed out a cross. Never to be resurrected. Rome wasn’t built in a […]

DNA & Protein Synthesis Model
*pictures at end* explain the structure of DNA – use the terms nucleotides, antiparallel strands and a complementary base pairing. DNA (Deoxyribonucleic acid) is shaped in a structure called a double helix, which looks like a twisted ladder. The ladder structure is made up of nucleotides that form the ladder shape. The DNA backbone is […]
3D Print Project
For this project I desinged a pulley and based my problem off one from the Systems of Masses worksheet we were given in class. I am looking for the tensions of the ropes. (images: left, orgiginal problem; right, the same problem but with my masses) I ignored possible friction and other forces that may be playing on […]
Dividing Rational Expressions
Dividing is very similar to multiplying other than the first 2 steps. 1. Flip the fraction on the right of the division sign (÷) 2. Change the division sign (÷) to a multiplication sign and multiply normally Click Multiplying Rational Expressions to see the rest of the steps Ex.
Multiplying Rational Expressions
When multiplying rational expressions it is very straight forward. You simply multiply across. Follow these simple steps: 1. Factor your fractions 2. Cancel out common factors in the pattern 3/1 +|- 1/2 +|- 2/ 3… 3. Multiply the numerators then multiply the denominators 4. You will now have your answer, add the non-permissible values (non-permissible […]
Adding & Subtracting Rational Expressions
When adding or subtracting (maybe even both in one expression) rational expressions the key aspect is that they share a common denominator. A common denominator means that the denominator of the fraction is all the same. To get to the point where you have a common denominator for all the fractions in the expression (if you don’t […]

– Radical/Root: √ ; ∛; etc.. – Radicand: √x – Index: ∛ (3 is the index of that radical) – Coefficient: x√y ; x(y) ; x(n/y) – Reciprocal: the flip of a fraction; 3/4 is the reciprocal of 4/3 – Exponent: the exponent is the opposite of a radical. bn – Square Root: √ – Cube Root: ∛ – Denominator: the […]
Fractions as Bases
As you may have seen in the previous two links when a fraction is the base you treat it like any other equation (make sure there are brackets). Even if the exponents are a fraction too, or if the exponent is a negative. Just remember to keep brackets around the fraction because exponents are lazy. Example […]
