Question

A construction company pours concrete at a constant rate to make a sidewalk. There are 1,054 cubic feet of concrete available, and 6.2 cubic feet of concrete is poured each minute. The equation below shows the total volume, in cubic feet, of concrete remaining t minutes after the construction company begins to pour the concrete.
C(t)=1,054−6.2tWhich statement BEST describes the domain of function C(t)?

A
The domain of C(t) is [0, 1,054] because the company can pour up to 1,054 cubic feet of concrete.

B
The domain of C(t) is (−∞, ∞) because the company can pour concrete for any number of minutes.

C
The domain of C(t) is [0, 170] because the company can pour concrete for up to 170 minutes.

D
The domain of C(t) is [170, 1,054] because the company can pour 1,054 cubic feet of c

Answer 1
