Two traffic signals are attached to the 36-ft support cable so that segment BC of it is 9.3 ft in length and is horizontal. Specify the necessary lengths AB and CD and the tensions in all three cable segments.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

false

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
