Question
A statement (A) and an argument (R) are given.
Statement (A): If carbon-dioxide increases, the glaciers will melt. Rationale (R): Earth's temperature will increase. Choose the correct option.Solution
The carbon dioxide envelope in earth's atmosphere traps the heat. With increase in the proportion of carbon dioxide, therefore, the global temperature would rise, thus causing the polar ice to melt.
I. 144x² - 163x - 65 = 0
II. 91y² - 128y -48 = 0
if x satisfies 3x² – 5x – 12 = 0, find the sum of reciprocals of roots.
I. p² - 10p +21 = 0
II. q² + q -12 = 0
l). 3p + 2q = 27
ll). 4p - 3q = 2
I. x2 - 11x + 24 = 0
II. y² - 5y + 6 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 4x² - 12x + 9 = 0
Equation 2: 2y² + 8y + 6 = 0
Roots of the quadratic equation 2x2 + x – 528 = 0 is
