a man bought a trampoline for his children to use. the trampoline has a diameter of 20 feet. if a man wishes to put up netting to go around the outside of the trampoline, how many feet of netting does he need? give the exact circumference of the trampoline and then approximate.

step-by-step explanation:

3024 rhe base is what up in worry about

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

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

faster, im not sure why but i know it is faster
