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:



![l = \sqrt[3]{\frac{138}{4} }](https://tex.z-dn.net/?f=l%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B138%7D%7B4%7D%20%7D)

Now, the second derivative offers a criteria to determine if solution leads to an absolute minimum:

(Absolute minimum)
The depth of the tank is:

are</h2><h2>

( 1),

,

(2) and

.</h2>
Step-by-step explanation:
We have:
The unit fraction = 
To find, the next four multiples of the unit fraction
= ?
∴ The next four multiples of the unit fraction
The first multiple = 
The second multiple = 
The third multiple = 
The fourth multiple = 
∴ The next four multiples of the unit fraction
are
( 1),
,
(2) and

Answer:
Distance between plane and airport is 134.4 miles.
Step-by-step explanation:
Given : An airplane leaves an airport and flies due west 150 miles and then 170 miles in the direction S 49.17°W.
To find : How far is the plane from the airport.
Solution : Distance from airport to west is 150 miles and then 170 miles in the direction south and angle form is S 49.17° W
Refer the attached picture for clearance.
Applying law of cosines


where a= 150 miles
b=170 miles
C= 49.17° angle in degree
c = distance between plane from the airport
Put values in the formula,






Therefore, Distance between plane and airport is 134.4 miles.
Answer:
1)= 1 kilogram per liter (kg/l) + 8.35 pound per gallon (lb/gal)
2)= 4.4704 meters per seconds
3)= 12in= 1ft ratio is 12:1
4)= 1ft=12in ratio is 1:12
5)= 3ft= 1 yard ratio is 3:1
6)=1 yard = 3ft ratio 1:3
Step-by-step explanation:
12 in = 1 foot
1 yard = 3 feet
1 yard = 36 in
