Discriminant

For all 'x', x^(2)+2ax+10-3a gt 0 , Statement 1 : the interval in which 'a' lies is -5 lt a lt 2 because Statement 2 : the sign of coefficient of x^(2) and the quadratic expression are same for all R iff the discriminant is negative.

Statement-1: If p is chosen at random in the closed interval [0,5], then the probability that the equation x^(2)+px+(1)/(4)(+2)=0 has real is (3)/(5) . Statement-2: If discriminant ge0 , then roots of the quadratic equation are always real.

Dr . Rajiv Mishra is working against the post of a senior doctor in a government hospital . He does not discriminate between the rich and poor while treating his patients medically . When he returns home from the hospital , he attends to the poor patients at home free of cost between 6 pm to 8 pm. Besides , he gives them the information about the employment opportunities . He advises many young people to go into the fields of advertising and transportation . They went into these fields and remarkably succeeded there. (i) What type of activites does Dr. Rajiv Mishra perform in the hospital and home ? (ii) Explain the auxiliaries to trade mentioned in the above para.

Assertion: Standard optical diffraction cannot be used for discrimination between different X-ray wavelengths. Reason: The grating spacing is not of the order of X-ray wavelengths.
