I would round it to 81.1. If the .039 was 5 or over, I probably would have gone to 81.2.
Hope I helped! Have a nice day!
-1/3(px-2) = 9
ok! so first we want to isolate x.
multiply both sides by -3/1 (this is the reciprocal of -1/3)
(px-2) = -27
px = -27 + 2
px = -25
x = -25/p
hope this helped!
Look in the images it is solved.
22.05 as a decimal and 22 1/20 as a fraction
D(√x + (1/4) sin (2x)^2)/dx = 1/(2√x) + (1/4) cos (2x)^2 * 8x = 1/(2√x) + 2x cos (2x)^2
