Answer:
Builder is right.
Step-by-step explanation:
circumference, C = 10 feet
Let the radius of circular window is r.
Use the formula for circumference.
C = 2 x π x r = 10 .... (1)
10 = 2 x π x r
r = 1.59 ft
The formula for the area of circular window
A = π r²
Differentiate with respect to r.
dA/dr = 2 x π x r
Differentiate again with respect to r.
d²A/dr² = 2 π
It is positive for any value of r so the area of minimum.
So, minimum area is
A = 3.14 x 1.59 x 1.59 = 8 ft
So, the minimum area id 8 ft². The builder is right.
Answer:
19.24 weeks
Step-by-step explanation:
Given that;
Mean, m = 18
Standard deviation, s = 3
Break down cost = 2000
Preventive maintenance cost = 1400
The optimal preventive maintenance level is Given by :
Mean + service level * standard deviation
Service level = preventive maintenance cost / (breakdown cost + preventive maintenance cost)
Hence,
Service level = 1400/(1400+2000) = 1400 / 3400
Service level = 0.4117647
Optimal preventive maintenance level :
18 + (0.4117647 * 3)
18 + 1.2352941
= 19.235
= 19.24 weeks
