Step-by-step explanation:

1/6 of 12 is 2

1/6 of 18 is 3

Plug them in

2z-3=2z-3

meaning you can put literally any number in place of z and it'd work.

Implicit differentiation in terms of x and y

Volgvan

For implicit differentiation, you are using the chain rule
$f'(x) = g'(u(x))* \frac{du}{dx}$
Except u(x) = y, So after every "y" term is differentiated it will be multiplied by dy/dx.

17) $y^3 +4 = 3x \\ 3y^2 \frac{dy}{dx} +0 = 3$
Then you solve for dy/dx as if its a variable.
$\frac{dy}{dx} = \frac{3}{3y^2} = \frac{1}{y^2}$

18) Here lets review product rule:
$(fg)' = f'g + fg'$
Take derivative of each term
$2x^2 = -3y^3 +3x^2y^3 \\ 4x = -9y^2 \frac{dy}{dx} + (6x)(y^3) + (3x^2)(3y^2 \frac{dy}{dx}) \\ 4x = -9y^2 \frac{dy}{dx} +6xy^3 +9x^2y^2 \frac{dy}{dx}$
Solve for dy/dx using factoring:
$4x - 6xy^3 = -9y^2 \frac{dy}{dx}+9x^2 y^2 \frac{dy}{dx} \\ 4x - 6xy^3 = \frac{dy}{dx}(-9y^2 +9x^2 y^2) \\ \frac{dy}{dx} = \frac{4x - 6xy^3}{-9y^2 +9x^2 y^2}$

What is 1/4 times 2/4

boyakko [2]

1/4= 0.25
2/4= 1/2 = 0.5
0.25 x 0.5 = 0.125
0.125 = 1/8

In how many distinct ways can the letters of the word mathematics be arranged? (first, does the order matter?)

TEA [102]

Our current list has 11!/2!11!/2! arrangements which we must divide into equivalence classes just as before, only this time the classes contain arrangements where only the two As are arranged, following this logic requires us to divide by arrangement of the 2 As giving (11!/2!)/2!=11!/(2!2)(11!/2!)/2!=11!/(2!2).

Repeating the process one last time for equivalence classes for arrangements of only T's leads us to divide the list once again by 2
