She begins with 4 kg of an alloy that is one-half tin. Keeping the amount of copper constant, she adds small amounts of tin to the alloy. Letting x be the total amount of tin added, define: C(x)=Concentration...
The safe load, L, of a wooden beam of width w, height H, and length l, supported at both ends, varies directly as the product of the width and the square of the height, and inversely as the length...
The value of a machine, V, at the end of t years is given by V=C(1-R)t , where C is the original cost and r is the rate of depreciation. Find the value of a machine at the end of 4 years if the...

A population grows exponentially at an annual rate given by r=0.03. What will the population be in 75 years if the initial population is 2500?
A stone dropped from rest travels 230 feet in the first 5 seconds. How far will it have fallen at the end of 7 seconds? (Round to the nearest Integer)
The revenue function is given by R(x) =x*p(x) dollars where x is the number of units sold and p(x) is the unit price. If p(x)=50(5)-x/5 find the revenue if 10 units are sold. Round to two decimal...
