Question
The Beaufort scale is for
describingÂSolution
The Beaufort scale is used for describing wind forces, both at sea and on land, and is based on observed sea conditions and effects on land features like trees and structures.
I. 63x2 + 148x + 77 = 0
II. 21y2 + 89y + 88 = 0
What is the nature of the roots of the quadratic equation x² – 5x + 7 = 0 ?Â
I. 56x² - 99x + 40 = 0
II. 8y² - 30y + 25 = 0
I. 2x2 – 10x – 48 = 0
II. y2 – 16y – 297 = 0
I. y/16 = 4/yÂ
II. x3 = (2 ÷ 50) × (2500 ÷ 50) × 42 × (192 ÷ 12)
I. 8a2 – 22a+ 15 = 0
II. 12b2 - 47b + 40=0
I. (x13/5 ÷7) = 5488 ÷ x7/5
II. (y2/3 × y2/3 ) ÷ √4 = (343y)1/3...
I. 2x² - 9x + 10 = 0
II. 3y² + 11y + 6 = 0
I. x² + 11x + 24 = 0
II. y² + 17y + 72 = 0
Solve: x² − 7x + 12 = 0
