.8 x + .4(10) = .64 (10+x) solve for x
Angle U =40 (which is 1/2 of 80)
Angle V = 17.5 (1/2 of 35)
angle Y = 180-40-17.5 = 122.5o
3 m / 45 mph = 1/15 hr = 4 minutes
you must drive that last mile in one minute or 60 mph
x = sqrt 33 * cos 130o = .........
y = sqrt33 * sin 130o= .........
Domain of the equation is the possible values of 'x'
x = 7 8 9 10 is the domain
If tan is positive then sin and cos are positive (Quadrant I ) or both are negative (quadrant III)
if csc (which equals 1/sin) is negative then cos must be negative also
arctan (1/2) = 26.565 degrees or 206.565 degrees cos = -.8944
Water will begin flowing into 2 before 3 from 2 bottle 6 will fill before any other
2 hours for 3 tasks 2/3 hour/task
2:00 + 2/3 hr/task * 1 task = 2:40
You didn't include the 'figure below' !
Three diameters + 24 = 2 diameters + 60
3x + 24 = 2x + 60
x = 36
