A water faucet leaked 2 and 3⁄5 liters of water over the course of 2 and 3⁄4 hours. How many liters would it have leaked after 4 hours?

p> q if you calculate p is100 q is 79

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

add a pic of the graph, then ill edit this "answer" and solve it for you : 3
