Step-by-step explanation:
Answer:
B. √14
Step-by-step explanation:
The line shows point R which looks like it is 3.7 and the square root of 14 is 3.748.... So it is closest to the point R on the line.
Hope This Helps :)
K = number of carpenters = 10
<span>C = 15,000+50(10)^2 +60x^2 </span>
<span>C = 15,000+5,000+60x^2 </span>
<span>C = 20,000+60x^2 ----- cost function </span>
<span>Marginal cost function = dC/dx = d/dx [60x^2] = 120x </span>
<span>MC = 120x ----- marginal cost function </span>
<span>Average cost function = C(x)/x = 20,000 /x + 60x </span>
<span>AC = 20,000/x + 60x
</span>Marginal cost when x=14 is:
<span>120(14) = 1,680 </span>
<span>Average cost when x=14 is: </span>
<span>20,000/14 + 60(14) = 2268.57
</span>
<span>Marginal cost is less than the average cost, so the average cost is decreasing as the number of electricians increases.</span>
Answer:
The measure of ∠D = (Q) = 28.81
Step-by-step explanation:
Tan(Q) = perpendicular/ base
In this case perpendicular is BC and base is DC
BC =25 DC = 45
Tan(Q) = BC/DC
Tan(Q) = 25/ 45
Tan(Q) = 5/ 9
(Q) = tan^ -1 (0.55)
(Q) = 28.81
