Answer:

9t + 4c ≤ 250

3t + 2c ≤ 80

Step-by-step explanation:

t is the number of tables

c is the number of chairs

Each table takes 9 hours to assemble and 3 hours to finish, so t tables take 9t hours to assemble and 3t hours to finish.

Each chair takes 4 hours to assemble and 2 hours to finish, so c chairs take 4c hours to assemble and 2c hours to finish.

Therefore, total assembly time is 9t + 4c.  Total finishing time is 3t + 2c.

Total assembly time is at most 250, and total finishing time is at most 80.

9t + 4c ≤ 250

3t + 2c ≤ 80

True [87]

Answer:

C

Step-by-step explanation:

V(t) = [x(t)]³

A(t) = 6[x(t)]²

dV/dt = k × 6[x(t)]²

Where k < 0

From the options,

taking k = -0.2

dV/dt = -1.2[x(t)]²
