Last year there were 205 ducks living on the pond. This year there are 20% more ducks living on the pond. Which equation would I use to solve this problem? * d = .20 x 205
d = 1.20 x 205
d = .80 x 205

the discriminant is 64 + 4*1*12 = 112

this is prime.

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

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
