Answer:
4+1m?? I’m pretty sure
Step-by-step explanation:
If this is in science terms its a plain if this is in mathematical terms, the answer is the number 0 anything below is negative, anything abouve is pos
A point (-0.8, 0.6) will be a point on the unit circle in the second quadrant. Since it is a unit circle, its radius is 1, and we have
sin(α) = y = 0.6
cos(α) = x = -0.8
tan(α) = y/x = 0.6/-0.8 = -0.75
The angle is α = arccos(-0.8) ≈ 143.13°
______
For the unit circle, the trig values are always the coordinates or their ratio as shown above, regardless of quadrant.
First you Change the mixed number to an improper fraction (14/3) then you simplify (1/4 X 7/3) and then you multiply 1/4 X 7/3 = 7/12 :)
you need to substitute.... then do: 160.4(mean)+2(x)*27(z)= 214.4lb
