C(x) should be ;
C(x)=0.9x² - 306x +36,001
Answer:
$9991
Step-by-step explanation:
Given :
C(x)=0.9x^2 - 306x +36,001
To obtain minimum cost :
Cost is minimum when, C'(x) = 0
C'(x) = 2(0.9x) - 306 = 0
C'(x) = 1.8x - 306 = 0
1.8x - 306 = 0
1.8x = 306
x = 306 / 1.8
x = 170
Hence, put x = 170 in C(x)=0.9x²- 306x +36,001 to obtain the
C(170) = 0.9(170^2) - 306(170) + 36001
C(170) = 26010 - 52020 + 36001
= 9991
Minimum unit cost = 9991
Answer:
no
Step-by-step explanation:
24 x 5 = 120
40 x 4= 160
Answer:
- Lower bound ⇒ 855 kg
- Upper bound ⇒ 865 kg
Step-by-step explanation:
The upper bound is the highest number that a figure can be to be rounded off to the rounded figure.
The lower bound is the lowest number that a figure can be to be rounded odd to the rounded figure.
The lower bound of 860 to the nearest 10 is;
= 855 kg
855 is the lowest figure that can be rounded up to 860.
The Upper bound is;
= 865
865 is the highest figure because no figure above this can be rounded to 860.
<em>855 kg ≤ 860 kg < 865 kg</em>
