Question
Alkali metals have ______. I. low melting
points II. low densitiesSolution
The alkali metals have relatively low melting point. They have a low density because alkali metals have a vast atomic radius and low weight.
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between 'p' and 'q' and choose...
I.70x² - 143x + 72 = 0
II. 80 y² - 142y + 63 = 0
Equation 1: x² - 180x + 8100 = 0
Equation 2: y² - 170y + 7225 = 0
I. 15b2 + 26b + 8 = 0
II. 20a2 + 7a - 6 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 36x + 288 = 0
Equation 2: y² - 36y + 320 = 0
I. x2Â - 9x - 52 = 0
II. y2Â - 16y + 63 = 0
I. 2x² - 12x + 16 = 0  Â
II. 4y² - 8y - 12 = 0  Â
I. x2 – 9x + 18 = 0
II. y2 – 5y + 6 = 0
I. 5x² - 24 x + 28 = 0  Â
II. 4y² - 8 y - 12= 0  Â
Between what values of x is the expression 19x - 2x2Â - 35 positive?
