Please can you clarify the following points
(i) should there be a + or - sign between x and 1?
(ii) do you mean everything in the bracket to the power of -3?
I would rewrite this as 20(x+1)^-3 or 20(x-1)^-3 where the ^ means 'to the power of'
If it is one of these last two, then differentiating you would get
-3*20*(x+1)^-4 or -3*20*(x-1)^-4 (8 means multiplied by )
or simplifying
-60(x+1)^-4 or -60(x-1)^-4

If the product of two numbers is 20 and if one of the numbers is 12 over 13 what is the other number?
(12/13)x = 20x = 20 / (12/13) = (20 x 13) / 12 = 21 and 2/3
What is the vertex to -5x2 plus 20x-13?
-5x2 + 20x - 13 describes a parabola, and you can find it's vertex in various ways. To find it using calculus, you can simply take it's derivative and solve for 0: f(x) = -5x2 + 20x - 13 f'(x) = -10x + 20 Let f'(x) = 0, then: 0 = -10x + 20 x = 2 Then simply plug the x value into the original equation: f(x) = -5 * 22 + 20 * 2 - 13 = -20 + 40 - 13 = 7 So the vertex of this parabola is at the point (2, 7). To solve it using strictly algebra, you can do it by expressing it as a value of y, and then rearranging accordingly: y = -5x2 + 20x - 13 y = -5(x2 - 4x) - 13 y = -5(x2 - 4x + 4 - 4) - 13 y = -5(x2 - 4x + 4) + 20 - 13 y = -5(x - 2)2 + 7 From which we can see that the vertex happens at the point (2, 7)
