2. When we solve a quadratic equation, how many solutions should we always start out seeking? Explain
why when solving a quadratic equation in the
form ax + bx+c=0 we may graph the equation
y= ax2 + bx + c and have no zeroes (x-intercepts).

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 number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
