Question
Which one of the following statements for a
tropographical map is not correct?Solution
Closely spaced contours represent steep slopes while widely spaced contours represent gentle slopes.Â
Equation 1: x² - 144x + 5184 = 0
Equation 2: y² - 130y + 4225 = 0
if x satisfies 3x² – 5x – 12 = 0, find the sum of reciprocals of roots.
I. 7x² + 52x + 21 = 0
II. 6y² + 7y - 24 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 21x² - 82x + 80 = 0
Equation 2: 23y² - 132y + 85 = 0
I. 5x + 2y = 31
II. 3x + 7y = 36
I. x2 – 13x + 36 = 0
II. 3y2 – 29y + 18 = 0
I. 40 x² - 93 x + 54 = 0
II. 30 y² - 61 y + 30 = 0
I. x2Â - 9x - 52 = 0
II. y2Â - 16y + 63 = 0
I. 117x² + 250x + 117 = 0
II. 54y² -123y + 65 = 0
Equation 1: x² + 16x + 63 = 0
Equation 2: y² + 10y + 21 = 0
