Before she went on a diet, jenna’s waist measured 32.45 inches. after the diet, it measured 26.97 inches. how many inches did jenna lose?

Jenna lost 5.48 inches off her waist.

32.45 - 26.97 = 5.48

Hope this helps.

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
