Question

can someone please check my work

Answer 1

find the dericative vales of \[\sqrt{x+5}\] \[1/x^2 +49 \] and x^2 - 16


I got 1/2sqrt x 2x and 2x

Answer 2

i mean (1/x^2 + 49)

Answer 3

Are these 3 separate questions?

Answer 4

yes

Answer 5

Derivative of y = (x+5)^(1/2) is (1/2)(x+5)^(-1/2) or can be written as 1/(2sqrt(x+5))

Answer 6

The derivative of 1/(x^2+49) is

(-2x/(x^2+49)^2)

Answer 7

Derivative of x^2 + 16 is just 2x.

Answer 8

Your second problem is (1/x^2) + 49?

Answer 9

I took the derivative of 1/(x^2+49)

Answer 10

thank you

Answer 11

ok.
