Answer:

a_n=-4n+10

Step-by-step explanation:

Let us consider the given terms one by one:

First term, a = 6

Second term, a_2=2

Difference between First and Second term = 2 - 6 = -4

Third term, a_3 = -2

Difference between Second and Third term = -2 - 2 = -4

Fourth term, a_4 = -6

Difference between Second and Third term = -6 -(-2) = -4

Therefore, the common difference is:

d = -4

Let the use the formula for n^{th} term of an arithmetic sequence:

a_n=a+(n-1)d

Putting the values of a and d:

a_n=6+(n-1)(-4)\\\Rightarrow a_n=6-4n+4\\\Rightarrow a_n=-4n+10

Therefore, the n^{th} term is:

a_n=-4n+10

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
7nadin3 [17]

Answer:

Widgets should be sold by $38.88 to maximize the profit.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

f(x) = ax^{2} + bx + c

It's vertex is the point (x_{v}, y_{v})

In which

x_{v} = -\frac{b}{2a}

y_{v} = -\frac{\Delta}{4a}

Where

\Delta = b^2-4ac

If a<0, the vertex is a maximum point, that is, the maximum value happens at x_{v}, and it's value is y_{v}.

In this question:

The profit is given by:

y = -9x^2 + 700x - 6005

Which is a quadratic function with a = -9, b = 700, c = -6005

The maximum profit happens at the x of the vertex. Thus

x_{v} = -\frac{b}{2a} = -\frac{700}{2(-9)} = 38.88

Widgets should be sold by $38.88 to maximize the profit.
