if the zeros of a quadratic function (parabola) are x=4 and x=8 , what is the equation of the Axis of Symmetry

3you can not round up to four, as there was not a full payment for the fourth night, so uou would round down to 3

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.

Element a has no reactivity because it has eight valence electrons and cannot gain anymore electron and it wouldn't lose any either
