Find the vertex (x,y) for a parabola with equation y=3x2−6x+1
For any parabola of the form ax2+bx+c, the x-coordinate of its vertex is x=−b2a So we have x=−(−6))2(3) = 1 We can plug this back into the original equation to find y: y=3(1)2−6(1)+1 = −2
Subject: Basic Math
Combine terms: 8a + 26b -4b – 12a
8a + 26b -4b – 12a. = 8a – 12a + 26b – 4b. = -4a + 22b
What economic value does water have?
Economic value, also termed as economic benefit, is the benefits and gain derived by individuals of a nation from the consumption of a commodity. Water has an economic value when its demand exceeds its supply. When this happens, the restricted supply makes water scarce, and individuals are willing to pay for it. The amount paid is the economic benefit individuals derive. When this is not the case, and supply exceeds the demand for water, water is used as a free good. Apart from this, water also provides economic benefits to people who are engaged in fishing, tourism, and habitat-related workplaces.
