Yandel will place a ramp over a set of stairs at the backyard entrance so that one end is 5 feet off the ground. the other end is at a point that is a horizontal distance of 40 feet away, as shown in the diagram. The angle of elevation of the ramp is represented by e°. Each step of the stairs is one foot long. What is the angle of elevation to the nearest tenth of a degree?

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

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

what? that isnt a question
