A triangle has a base of x½ m and a height of x¾ m. If the area of the triangle is 16 m2, what are the base and the height of the triangle?

Base = 4.62m,   Height = 6.93m

Step-by-step explanation:

I worked through the black first, then went to the blue.

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
