Linear Algebra - Question
I have this number that I just wanted to be sure how to do. They give me a Parallelepiped with corners lettered from A to H. Then the question is: In a certain orthonormal reference, the coordinates of points A, B, D and E are respectively A(0,0,2) B(3,0,2) D(0,4,2) E(0,0,1) C...

y = 1 + (x-1)^(1/2) Considering the interval (2,4), calculate delta(y) and dy. would delta(y) be: delta(y) = f(4) - f(2) = (1 + squr(3) ) - 2 = squr(3) - 1 and dy is 1/(2 squr(x-1)) dx Thank you

a. Suppose a market research company finds that at a price of p = \$6., they would sell x = 44 tiles each month. If they lower the price to p = \$2, then more people would purchase the tile, and they can expect to sell x = 48 tiles in a month’s time. Find the equation of th...
