The prism below has a volume of 21 cubic units. The base is a right triangle with legs that have lengths of 2 units and 3 units. Find
the height of the prism.

OA) 7 units
OB) 3.5 units
OC) 21 units
OD) 11.5 units

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
