Lines m and n are perpendicular. if the slope of m is zero, then the slope of n is
zero
undefined
negative

When two lines are perpendicular to each other, then the product of slopes of both lines is equal to “-1”.

Let the slope of line “m” is n1 and slope of line “n” is n2, then ;

n1 x n2 = -1

As per question conditions, n1 = 0;

So n2 = -1/0

Hence n2 = undefined. Thus 2nd option is correct. 

undefined

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

2, 2, 2 or -4, 20, 29
