Azookeeper predicted the weight of a new baby elephant to be 274 pounds when it was born. the elephant actually weighed 306 pounds at birth. what was the percent error of the zookeeper's prediction?

About 11%

Step-by-step explanation:

I first subtracted 250 from 282, to get 32. I then did 32/282 to get .11 You round that out to about 11%

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

doubled
