The amount of time it would take you to go from chicago to las vegas is equal to 1525 miles divided by your average rate of travel. which equation describes how the time and rate of travel are related?

Step-by-step explanation:

time = distance / rate of travel

time * rate of travel = distance = 1525 miles

uhhh idk u yolo?

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
