Given the points J(4, -7) and L(-2, 13), find the coordinates of point K on JL such that the ratio of JK to JL is 1:4.

a .4y4

hope this !

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

the answer is 99.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.
