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.
Answer:

Step-by-step explanation:
The arcs LY, KM, KL and MJ together form the full revolution angle, thus

Note that

then

So,

Also

so

In triangle EML,

Thus, 
9.58 = 9 58/100 = 9 29/50
