Two hikers are 11 miles apart and walking toward each other. they meet in 2 hours. find the rate of each hiker if one hiker walks 1.1 mph faster than the other.

8 2/3 is the answer

step-by-step explanation: just use a calculator

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
