The cost of manufacturing clocks is given by $C ( x ) = 72 + 62 x - x ^ { 2 }$. Also, it is known that in thours the number of clocks that can be produced is given by x=9t , where $1 \leq t \leq 12$ Express C as a function of t . A) C(t)=72+62t-9 B) C(t)=72+558t-81t² C) C(t)=72+62t+t² D) C(t)=72+558t-81t

Question

Quizplus · Accepted Answer

Substitute x=9t into C(x) to get C(t) = 72 + 62(9t) - (9t)^2 = 72 + 558t - 81t^2

The Cost of Manufacturing Clocks Is Given By C(x)=72+62x−x2C ( x ) = 72 + 62 x - x ^ { 2 }C(x)=72+62x−x2

The Cost of Manufacturing Clocks Is Given By $C ( x ) = 72 + 62 x - x ^ { 2 }$
