$2.36 per cup. there are two cups in a pint, so if there are 2 pints then there are 4 cups. 9.44/ 4 is 2.36
To get minimized number of x steel bars, we differentiate the equation and then equate to zero:
d/dx (C(x) = 0.02x² – 3.4x + 150)
C'(x) = 0.02(2)x – 3.4 = 0
Solving for x
0.04x – 3.4 = 0
x = 85 steel bars
For minimum cost,
C(x = 85) = 0.02(85)² – 3.4(85) + 150 = 5.5 dollars
Answer:
5 + 2x
Step-by-step explanation:
Called the unknown number "x"
The problem essentially says;
5 + 2x
Answer:
1.486713333333333
Step-by-step explanation:
Step 1:
Add all 4 together.
1.5 + 15 + 0.67056 + 0.67
Step 2:
Divide by 4.
17.84056 ÷ 4
1.5 mph = 0.67056 m/s
20% is your percent m of error in this problem
