Answer:
Step-by-step explanation:
We are given the following in the question:
A storage shed is to be built in the shape of a (closed) box with a square base.
Volume = 150 cubic feet
Let s be the edge of square base and h be the height.
Volume of cuboid =
where l is the length, b is the base and h is the height.
Volume of box =
Area of base =
Cost of concrete for the base = $4
Cost of base($) = 
Area of roof =
Cost of material for the roof = $2
Cost of roof ($) = 
Area of 4 walls =
Cost of material for the side = $2.50
Cost of material of side($) =
Total cost
= Cost of base + Cost of 4 sides + Cost of roof
is the required cost function.

Answer:
The reaction ca occur at 10 degree Celsius or -14 degree Celsius.
Step-by-step explanation:
We are given the following in the question:
The completion of a chemical reaction is expressed by the equation
where y is the number of seconds needed to complete the reaction and x is the temperature in degrees Celsius at which the reaction occurs.
We have to find the temperature at which the reaction occurs, if the completion time of reaction is 160 seconds.
Putting y = 160
Thus, the reaction ca occur at 10 degree Celsius or -14 degree Celsius.
Write it in y= mx+b form. Subtract 5x from both sides to get 4y = -5x + 100. Divide by 4 so the answer would be y= -5/4x + 25.
Answer: The answer would be f^-1 (x) = x/2 - 3/2
