Wittaler [7]

Answer:

RD = 162 cm

Step-by-step explanation:

LD = 2 RL = 2* 54 = 108

RD = RL + LD

RD = 54 + 108

Find f^3(x) for f(x)=4/x^2
vaieri [72.5K]

Answer:

  f³(x) = 64/x⁶

Step-by-step explanation:

  f³(x) = (f(x))³ = (4/x²)³ = 4³/(x²)³

  f³(x) = 64/x⁶

_____

The applicable rules of exponents are ...

  (a/b)^c = (a^c)/(b^c)

  (a^b)^c = a^(bc)

f(6)= 7        f(11)= 22

f(7)= 10  

Step-by-step equation:

f(6)= 3(6)-11  = 7\\f(7)= 3(7)-11  = 10\\f(11)= 3(11)-11  = 22

Answer:

remaining cardboard area =  122.5πr²

Step-by-step explanation:

area of original rectangle = length * width                                                                      

                                          =  18r * 8r

                                           =     144r²

  • area of semi circle: \frac{1}{2}πr²

Here we have 3 semi circles with radius 3r:

  • area of 3 semi circles:  3( \frac{1}{2} * π * (3r)²)

                                   : 3( \frac{1}{2} * π * 9r²)

                                    : 13.5πr²

  • area of one semi circle with radius 4r:

                       ( \frac{1}{2} * π * (4r)²)

                       ( \frac{1}{2} * π * 16r²)

                             8πr²

  • So the area of remaining cardboard:

            area of rectangle - area of 4 semi circles

                        144r² - 13.5πr² - 8πr²

                                122.5πr²
