First start by considering the x⁰ coefficient which is -3. These include ±3 and ±1. Substituting x=1 into the polynomial produces an answer of 0 which shows that x=1 is a factor of the polynomi...

To understand the question, we have to know what a third is. 1 is made up of three thirds (3/3 presented in a fraction), so in order to obtain 9 we must multiply it by 3. The answer is 27.

Motion is a topic in physics that is sometimes hard to understand. When we talk about motion we think about acceleration, velocity, time and displacement. In the case of projectile motion, we usually disc...

An action potential depolarises the sarcoma and depolarisation travels down the T-tubules to the sarcoplasmic reticulum, which releases Ca²⁺ (calcium ions) to the sarcoplasm. Ca²⁺ ca...

To do the product rule you must have two functions multiplied together. Here you must make one function be u and the other be v. The formula from this is uv’+vu’ where v’ and u’ are the differentials of t...
