If f is a differentiable function, find an expression for the derivative of each of the following functions
almond37 [142]

12a. Answer:  d) x⁶ f'(x) + 6x⁵ f(x)

<u>Step-by-step explanation:</u>

Use the multiplication formula for derivatives:

y = a · b       →     y' = a'b + ab'

<u>y = x⁶ · f(x)     </u>  

a = x⁶          b = f(x)

a' = 6x⁵       b' = f'(x)

<u>y' = a'b + ab'</u>

y' = 6x⁵ f(x) + x⁶ f'(x)

***************************************************************

12b. Answer:  \bold{b)\ y=\dfrac{xf'(x)-9f(x)}{x^{10}}'}

<u>Step-by-step explanation:</u>

Use the division formula for derivatives:

y=\dfrac{a}{b}       →     y' = \dfrac{a'b - ab'}{b^2}

y=\dfrac{f(x)}{x^9}\\\\a=f(x)\qquad b=x^9\\\\a'=f(x)\qquad b'=9x^8\\\\y'=\dfrac{a'b-ab'}{b^2}\\\\y'=\dfrac{x^9f'(x)-9x^8f(x)}{(x^9)^2}\\\\.\ =\dfrac{x^9f'(x)-9x^8f(x)}{x^{18}}\\\\\text{factor out }x^{8}: y'=\dfrac{xf'(x)-9f(x)}{x^{10}}

Note: You can also move the denominator to the top (it will have a negative exponent) and use the multiplication formula for derivatives.

the sides of a triangle are 3 whole 1 by 6 cm 4 whole 2 by 3 cm and 5 whole 2 by 3 cm. Find the total length of the three sides
Lyrx [107]

Answer:

16\frac{2}{3}cm

Step-by-step explanation:

Given dimensions:

           3\frac{1}{6} cm by 4\frac{2}{3}cm  by 5\frac{2}{3} cm

The total length:

 it is the sum of all the sides;

         \frac{19}{6}  + \frac{14}{3}   + \frac{17}{3}  

LCM of the denominators = 6 ;

   \frac{38 + 28 + 34}{6}  = \frac{100}{6}

                 = \frac{50}{3}

                 = 16\frac{2}{3}cm
