Answer:
2.5 ft
Step-by-step explanation:
A rectangular prism's volume is given by it's base area multiplied by it's height:
In this problem, we are given the volume and the base area, so we need to solve for h:
The units are feet, so the answer is 2.5 ft.
(f-g)(x) = 2x² + 1 - x² + 7 = x² + 8
The answer I got is 420. Since 4.20 = 420/100
We are given the statement that the strength, S, of a beam of width w andheight h is proportional to wh2. hence using k as the proportionality constant, the equation is S = k wh2. the exact width and height can be determined by applying optimization to the problem. optimization is taking the first derivative of an equation and equating then to zero
