The one with the word bank is in this order, right angle, acute angle, straight angle and then obtuse then you try to guess an estimate a right angle is always a 90 degree angle and a straight angle is always 180 degrees the given part of the angle would be subtracted by 180 for example 180-130 which means X= 50 degrees

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}

The equation y = 8.1x models the relationship between the number of hours Alexander works, x, and the dollar amount he earns, y.
Katarina [22]
Start the graph at the <em>y</em>-intercept.  At 0 hours, he will make $0, so (0, 0) is the <em>y</em>-intercept.  From this point, he makes $8.10 an hour; go up 8.1 for every 1 hour you go over on the graph.  The graph is attached.
