Lynn, Jude, and Anne were given the function f(x)=-2x^2+32, and they were asked to find f(3). Lynn's answer was 14, Jude's answer was 4, and Anne's answer was +4. Who is correct

Lynn is correct.  f(3) = 14

Step-by-step explanation:

f(x)=-2x^2+32

f(3)=-2(3)^2+32

f(3)=-2(9)+32

f(3)=-(18)+32

f(3) = 14

Lynn's answer is correct

Step-by-step explanation:

f(3) = -2 x 3^2 + 32

     = -2 x 9 + 32

     = -18 + 32

     = 14

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
