A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit. Y=-44x^2+1375x-6548

The selling price of each widget is 15.63 cents.

Step-by-step explanation:

A quadratic function or function of the second degree is a polynomial function of the form:

f(x)= a*x² + b*x + c;  or  y=a*x² + b*x + c

The maximums and minimums in a function f are the largest (maximum) or smallest (minimum) values or extremes that the function takes. The vertex is a point that is part of the parabola that coincides with the maximum or minimum of the function:

In this case you know that the amount of profit, y, made by the company is related to the selling price of each widget, x, by:

y= -44*x²+1375*x-6548

In this case, comparing with the form of the quadratic function:

So, since the value of a is less than zero, the vertex will be the maximum of the function. Therefore, the vertex will indicate the price at which the devices should be sold for the company to obtain the maximum profit.

The value of the vertex on the abscissa axis (the x-axis) is:

In this case:

x= 15.63

Since x represents the selling price of each widget, then this will be 15.63 cents.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
