With a tailwind , a bird flew at a ground speed of 3mi/h. Flying the same path against the same wind, the bird travels at a ground speed of 1.5mi/h. What is the bird's air speed? what is the wind speed?

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

answer: sine

step-by-step explanation:

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
