Find the slope of the curve x=6t+3, y=2t2−7t at t=5. A) 13. B) 0. C) 6. D) 136.Slope:We have parametric equations that are quadratic and linear in nature. The slope of the curve at any point is the tangent of the angle that th...
This is supported by the fact that as the team size increases linearly, the links between people increases quadratically; thus the cost of coordinating and communicating also grows quadratically. If this cost of coordination is essentially overhead, then smaller teams should be preferred. The ...
square root of 9 is a whole number that is multiplied by itself to get the original number. the actual value of square root of 9 is 3. √9 = ±3 if we square +3 or -3, the resulting value will be equal to 9. (+3) 2 = 9 (-3) 2 = 9 note: since, the square root of...
