After t hours of operation, an assembly line has assembled A(t)=19t-1/2t^2 power lawn mowers, 0 = < t = < 10 . Suppose that the factory's cost of manufacturing x units is C(x) dollars, where C(x) dollars=2657+70x.

a. Express the factory's cost as a composite function of the number of hours of operation of the assembly line.
b. The cost of the first 2 hours of operation is $___.

Respuesta :

Answer:

a.   [tex]C(A(t)) = 2657 + 1330t - 35t^2[/tex]

b.    the cost of the first 2 hours of operation is $5177

Explanation:

From the given information:

a.  The factory's cost as a function of the number of hours of operation of the assembly line can be expressed as:

[tex]C(A(t)) = C ( 19t - \dfrac{1}{2}t^2)[/tex]

[tex]C(A(t)) = 2657 + 70 ( 19t - \dfrac{1}{2}t^2)[/tex]

[tex]C(A(t)) = 2657 + 1330t - 35t^2[/tex]

b.   Replacing t = 2 in the above equation, we have:

[tex]C(A(t)) = 2657 + 1330t - 35t^2[/tex]

[tex]C(A(2)) = 2657 + 1330(2)- 35(2)^2[/tex]

[tex]C(A(2)) = 2657 + 2660- 140[/tex]

[tex]C(A(2)) =5317- 140[/tex]

[tex]C(A(2)) =5177[/tex]

Hence, the cost of the first 2 hours of operation is $5177

The activities that help in the management of the various managerial activities are the operational activities. These activities aid in the function of the different activities of the firm.  

a.  [tex]C(A(t))=2657+1330t-35t^{2} \\[/tex]  

b.    The cost of the first 2 hours of operation is $5177

a.  The factory's cost as a function of the number of hours of operation of the assembly line can be expressed as:

[tex]C(A(t))=C(19t-\frac{1}{2}t^{2})\\C(A(t))=2657+70(19t-\frac{1}{2}t^{2})\\C(A(t))=2657+1330t-35t^{2}[/tex]

b.   Replacing t = 2 in the above equation:

[tex]C(A(t))=2657+1330t-35t^{2} \\C(A(2))=2657+1330(2)-35(2)^{2}\\C(A(t))=2657+2660-140\\=5177[/tex]

Hence, the cost of the first 2 hours of operation is $5177
