Write the following in standard form: 6x^3-8x^4+5x+12x^2-9
kondaur [170]

Answer:

-8x^4 + 6x^3 + 12x^2 + 5x -9

Step-by-step explanation:

To write a polynomial in standard form, list its terms from highest to lowest degree. The degree of a term is represented by its exponents. Thus, rearrange the terms so that the terms with the highest exponents are first and the ones with the lowest are last.

6x^3-8x^4+5x+12x^2-9\\-8x^4 + 6x^3 + 12x^2 + 5x -9

Thus, -8x^4 + 6x^3 + 12x^2 + 5x -9 is the answer.

A company sells widgets. The amount of profit, y, made by the company, is
denis23 [38]

Answer:

449.25 units

Step-by-step explanation:

The amount of profit, y, made by the company, is  related to the selling price of each widget, x, by the given equation as follows :

y=-x^2+51x-201 ...(1)

For maximum profit,

Put dy/dx = 0So,

\dfrac{d}{dx}(-x^2+51x-201)=0\\\\-2x+51=0\\\\x=\dfrac{51}{2}\\\\x=25.5

Now put x = 25.5 in equation (1).

y=-(25.5)^2+51(25.5)-201\\\\y=\$ 449.25

so, the required answer is 449.25 units.

Oneta writes an algebraic expression with three terms. The y-term has a coefficient of -3, and the x-term has a coefficient of 1
Snowcat [4.5K]

Answer:

x - 3y + z

Step-by-step explanation:

Terms are just names for objects inside the equation -- anything that isn't an operation. A coefficient the is the number a given term (variable) is being mulitpled by. In this case, -3 for y, and 1 for. x. We can deduce from this the start of the expression (x has no coeff. bc of multiplicative identity)

x - 3y

We know we are missing one term, and we also know that the third term cannot be constant, so it must be another variable. In this case I have chosen Z, in theory it shouldn't really matter but z is the best variable name in this case.
