Decrease in consumption = [25/(100+25)] × 100 = [25/125]×100 = 20 Hence , consumption of onion should be decreased by 20 % so that there is no change in the expenditure.

We have to find the equation of circle whose diameter is join of the point (x₁,y₁) and (x₂, y₂) . Let A ≡ (x₁,y₁) and B ≡ (x₂,y₂) Then, equation of circle is given by (x - x₁)(x - x₂) +(y - y₁)(y - y₂) = 0 [ by formula ] x² - (x₁ + x₂)x + x₁x₂ + y² - (y₁ + y₂)y + y₁y₂ = 0 x² + y² -(x₁ + x₂)x - (y₁ + y₂)y + x₁x₂ + y₁y₂ = 0 Hence, the equation of circle is x² + y² -(x₁ + x₂)x - (y₁ + y₂)y + x₁x₂ + y₁y₂ = 0 Hope this answer will help u....

Posted by Preet Dhillion 7 years ago

Ayushi Ayushi 7 years ago

Mathematical reasoning is the critical skill that enables a student to make use of all other mathematical skills. With the development of mathematical reasoning, students recognize that mathematics makes sense and can be understood. They learn how to evaluate situations, select problem-solving strategies, draw logical conclusions, develop and describe solutions, and recognize how those solutions can be applied. Mathematical reasoners are able to reflect on solutions to problems and determine whether or not they make sense. They appreciate the pervasive use and power of reasoning as a part of mathematics.
