nature of the roots of quadratics and cubic functions. Part One Case One For Case One‚ the discriminant of the quadratic will always be equal to zero. This will result in the parabola cutting the axis once‚ or twice in the same place‚ creating a distinct root or two of the same root. For PROOF 1‚ the equation y=a(x-b)2 is used. PROOF 1 y = 3 (x – 2)2 = y = 3 (x2 – 4x + 4) = y = 3x2 – 12x + 12 ^ = b2 – 4ac = (-12)2 – 4 x 3 x 12 = 144 – 144 = 0 The discriminant is equal to zero. The parabola

This process involves a solution of known concentration delivered from a buret into the unknown solution until the substance being analyzed is just consumed.

Around the age of 2 years they are generally walking and running. Intellectually they begin to recognise their carers and develop a memory for actions and sounds. They develop co-ordination and begin to enjoy role play and music. A baby’s language begins to develop from the moment they are born in the form of crying. They begin

Unit 1: Introduction to Biochemistry Lesson 1-4: Key Question How many electrons does Mg2+ have? (1 mark) Mg2+ has 10 electrons. A magnesium atom has 12 electrons with 2 of the 12 being valence electrons. Therefore the atom will lose the valence electrons which are located on the outermost shell to stabilize itself (outermost shell) as atoms tend to do what it easiest. Since magnesium lost 2 electrons it becomes positive as it is giving away electrons to stabilize other atoms. Hence magnesium
