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

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

What four consecutive intergers have a sum of -34

Ivenika [448]

Answer:

-7, -8 , -9 and -10 are such four integers.

Step-by-step explanation:

Let the first integer = k

So, the next three consecutive integers are ( k+1), ((k + 1) + 1) and (((k + 1) + 1) +1)

or, k , (k +1), (k +2) and (k +3) are four consecutive integers.

Now, their sum is -34.

⇒k + (k +1) + (k +2) + (k +3) = -34

or, 4k + 6 = -34

or, 4k = - 34 - 6 = -40

⇒ k = -40/ 4 = -10

Hence, the first integer k = -10

The next integer = k + 1 = -10 + 1 = -9

Similarly next two integers are -8 and - 7.

So -7, -8 , -9 and -10 are such four integers.
