Plug in 31 where h is assuming that's what the variable h represents.
31 - 15 = 3.2t
16 = 3.2t
Divide both sides by 3.2
t = 5
Answer:
both are A but i do not really know
Step-by-step explanation:
The marginal cost curve is generally upward-sloping, because diminishing marginal returns implies that additional units are <span>more costly to produce.
The graphical relation or connection which formed a U-shaped curve that is between marginal cost and yield is known as marginal cost curve and it is comparatively high when there is output in small quantities, and when the mount of product increases it declines and approaches a minimum value and then rises again.

We will use substitution for the partial integration:
The integral becomes:=
2nd integration:
we will add and subtract x^2 to the numerator:
u-substitution:
...=
Finally:...=
