Can someone explain to me this derivative : y=3x√x
dimaraw [331]

Answer:

(9/2)√x.

Step-by-step explanation:

Convert the radical to an exponent.

x√x = x^1 * x^1/2

= x^(1 + 1/2)

= x^3/2

So the derivative of 3x^3/2 is found as follows:

y' = 3 * 3/2x^(3/2 - 1)

= (9/2)x^1/2

= (9/2)√x.

What Is the line of reflection between pentagons PQRST and P'Q'R'S'T' ?
Sergeu [11.5K]

Answer:

A

Step-by-step explanation:

From the diagram:

  • P(-4,6)→P'(4,6);
  • Q(-7,4)→Q'(7,4);
  • R(-6,1)→R'(6,1);
  • S(-2,1)→S'(2,1);
  • T(-1,4)→T'(1,4).

The general rule of this reflection is

(x,y)→(-x,y)

and this is reflection across the y-axis. The y-axis has the equation x=0.
