Alattice point is a point whose coordinates are both integers. how many lattice points are on the boundary or inside the region bounded by the $x$-axis, the line $x=4$ and the curve $y=2\sqrt{x}$?

answer:

mmhhhu not sure

step-by-step explanation:

try to look on line maybe that will i look up stuff all thre time

2x3 – 6x2 – 14x + 24 square centimeters

if i'm wrong i'm sorry : )

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
