A baseball player hits a high pop-up with an initial velocity of 32 meters per second, 1.3 meters above the ground. The height h(t) of the ball in meters t seconds after being hit is modeled by h(t)=−4.9t2+32t+1.3.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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
