riadik2000 [5.3K]

Answer:

y' = 9x^2 + 8x^-5

Step-by-step explanation:

General Principle

y' = ax^b

y' = a*b * x^(b-1)

Solution

3x^3 = 3*3x^(3-1)

3x^3 = 9x^2

-2x^-4  = -2*-4 x ^(-4 - 1)

-2x^-4 = 8 x ^-5

Answer

y' = 9x^2 + 8x^-5

In the right triangle, angle B equals 60° and AB equals 18<br><br>How long is AC? <br>I'm stuck!
svlad2 [7]

Answer:

AC = 15.588

Step-by-step explanation:

(all rounded to nearest thousandth)

sin(60) = x/18

first solve: sin(60) = 0.866

0.866 = x/18

multiply 18 on both sides

x = 15.588
