Sep 23, 2017 · Explanation: We write the matrix and the identity matrix side by side and perform the row operations

See explanation. a. Calculate the inverse function. y=x^3-18 y+18=x^3 x=root (3) (y+18) So the inverse function is: g (x)=root (3) (x+18) b. Calculate the derrivative ...

Jun 18, 2018 · Both equations are partial variations Neither is a direct nor an inverse variation. For a partial variation the value of one variable is: color (white) ("XXX")a constant times the value of the …

After using #x-2=2sinu#, #sinu= (x-2)/2#, #cosu=sqrt (4x-x^2)/2# and #tanu= (x-2)/sqrt (4x-x^2)# inverse transforms, I found #int (x-2)^2/ (sqrt (4x-x^2))^5*dx#

How do you determine whether the situation is an example of an inverse or direct variation: the drama club can afford to purchase 10 wigs at $2 each or 5 wigs at $4 each?

Dec 16, 2017 · Explanation: #x = (y / (1-2y^2))^ (1/2)# Making ^2 both sides of eq: #x^2 = y / (1-2y^2)# Making inverse both sides of eq: #1/x^2 = (1+2y) /y# #1/x^2 = 1/y+2# Re-arranging for y: #1/y = …

Since f(x) = x-tan^-1(3x) is a continuous function, all we need to show is that the signs of f(1) and f(2) are opposite. The intermediate value theorem of real analysis states that if a continuous function, f, …
