Let r(d) represent the monthly revenue, in dollars, from selling skateboards when the price of a skateboard has been decreased by a specific amount d times. which representation of the revenue function would be most in determining the maximum revenue earned by the sale of skateboards? brainliest to whoever answers correctly kinda losing my mind at this point

Step-by-step explanation:

Here r(d) represents the monthly revenue, in dollars, from selling skateboards when the price of a skateboard has been decreased by a specific amount d times.

As r(d) is a quadratic function, it represents a parabola. When the parabola opens downwards, at the vertex the value of the function is the maximum value of the function.

The vertex form of parabola with vertex at is,

The standard form of parabola is,

where vertex is

In equation 1, the leading coefficient or the coefficient of maximum power i.e d² will be negative, so it opens downward and focus is at Hence, the maximum revenue earned will be $122,500.

But all the remaining cases you have to take them to standard form then only applying formula you can get the coordinates of vertex.

Therefore, equation A representation of the revenue function would be most helpful.

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%
