<span>2 significant digits.
       
Let's see what the range of possible values you can have for 1.3540980 if your uncertainty is +/- 2% 2% of 1.3540980 = 0.02 * 1.3540980 = 0.027082 So the lowest possible value for your result is 1.3540980 - 0.027082 = 1.327016 The largest possible result is 1.3540980 + 0.027082 = 1.38117996 Notice that only the 1st 2 digits of the result match which is reasonable since a 2% error means that your result is only accurate to within 1 part in 50.</span>

Answer:

The slope of the perpendicular line to the line is

m   = \frac{-1}{2}

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the line y =f(x) = 2x +6

                           ⇒  y = 2x +6

 comparing             y =mx +c

The slope of the given line   m =2

<u><em>Step(ii):- </em></u>

The slope of the perpendicular line   = \frac{-1}{m}

The slope of the perpendicular line   = \frac{-1}{2}
