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
lora16 [44]

Answer:

The maximum amount of profit the company can make is $854.08

Step-by-step explanation:

Let

x ----> the selling price of each widget

y ---> the amount of profit

we have

y=-3x^{2} +155x-1148

This is the equation of a vertical parabola open downward (because the leading coefficient is negative)

The vertex represent a maximum

so

The y-coordinate of the vertex represent  the maximum amount of profit the company can make

using a graphing tool

Find out the vertex of the quadratic equation

The vertex is the point (25.83,854.08)

see the attached figure

The y-coordinate of the vertex is 854.08

therefore

The maximum amount of profit the company can make is $854.08

The area of the triangle is 28.7 square centimeters. What is the base length of the triangle in centimeters?
Montano1993 [528]

In order to derive the base of a triangle from its area, you need its height as well.

In fact, if we solve the area formula for the base, we have

A=\dfrac{bh}{2} \iff 2A = bh \iff b=\dfrac{2a}{h}

So, the base length would be

b=\dfrac{2\cdot 28.7}{h} = \dfrac{57.4}{h}

where h is the height relative to the base you're interested in.
