Answer:
2x + 2y = 7
Step-by-step explanation:
(x + 2)2 + (y + 1) = 13
2x + 4 + 2y + 2 = 13
2x + 2y = 7
Given
Hourly rate of labor = $12.00
Duration of job = 3 1/2 hours
Overhead rate = 66 2/3%
Price of parts = $112.50
Answer
Rate for 3 1/2 hr =12 x 3 1/2 = 12 x 7/2 = $ 42
Overhead rate 66 2/3 % of $42 = 28
Total cost job = 112.50 + 28 + 42 = $182.50
Yes you can classify by sides but I’m not sure about angles
Answer:
,
Step-by-step explanation:
The equations of volume and surface area are presented below:
The length of the tank is:
The expression fo the surface area is therefore simplified into an univariable form:
The first and second derivatives of the expression are, respectively:
The first derivative is equalized to zero and length of the square side is now found:
Now, the second derivative offers a criteria to determine if solution leads to an absolute minimum:
(Absolute minimum)
The depth of the tank is:
<span>2/3+y−1/9=7/9
y = 7/9 + 1/9 - 2/3
y = 8/9 - 2/3
y = 8/9 - 6/9
y = 2/9</span>
