Answer:
The number of watches must he repair to have the lowest cost is 54.
Step-by-step explanation:
The cost of operating Bob's shop is given by

Differentiate the given function with respect to x.

... (1)
Equate C'(x) equal to 0, to find the critical point.


Divide both sides by 4.


Differentiate C'(x) with respect to x.

C''(x)>0, it means the cost of operating is minimum at x=54.
Therefore the number of watches must he repair to have the lowest cost is 54.
Answer:
48x³y²
Step-by-step explanation:
The LCM of the numbers 12 and 16 is their product divided by their greatest common factor: (12·16)/4 = 48.
The LCM of the xy terms is the product of highest powers of x and y. Both those powers are in the first term, so the LCM of the given terms is ...
48x³y²
Let x be the amount that Jeff spent for the food and medication of his dog. With this representation, the cost of food and medication for each cat is 2x/3 - 5. The equation that best represent the given situation is
x + 6(2x/3 - 5) = 195
The value of x from the equation is 45. Jeff spent $45
Answer:
u=-1
Step-by-step explanation:
if you replace with a or b the answer on the left side is actually bigger since it is closer to 0 than -20. same with choice d
choice c makes -12-28 which is a smaller value than -20
For this case the volume of the box is given by:
V = l * w * h
Where,
V = 24 feet ^ 3
Substituting values we have:
24 = l * w * h
Clearing the value of h we have:
h = 24 / (l * w)
Answer:
The height in terms of the other sides is:
h = 24 / (l * w)
