What is the factored form of this expression? x^3-6x^2-9x+54
Nesterboy [21]

The factored form of this expression is (x+3)(x-3)(x-6)

<h3>Factored form of an expression</h3>

Given the polynomial function

x^3-6x^2-9x+54

Group

(x^3-6x^2)-(9x+54)

Factor out the greatest common factor

x^2(x-6) - 9(x- 6)

Find the factors

(x^2-9)(x-6)

using the difference of two square

(x+3)(x-3)(x-6)

Hence the factored form of this expression is (x+3)(x-3)(x-6)

What are the values that satisfy the trigonometric equation for: 0≤q≤2π ?<br> sin(∅)+tan(−∅)
Mrac [35]

Answer:

First choice: 0, pi

Step-by-step explanation:

I am assuming the equation is

\sin q + \tan (-q) = 0

(the =0 part is missing in the original problem)

\sin q + \tan (-q) = 0\\\sin q + \frac{\sin (-q) }{\cos (-q)} = 0\\\sin q + \frac{-\sin q}{\cos q}=0\\\sin q = \frac{\sin q}{\cos q}\\\sin q \cdot \cos q = \sin q\,\,,\,\,\, 0\leq q \leq 2\pi\\\implies\\\cos q = 1 \implies q=\{0, 2\pi\}\\\mbox{or}\\\sin q = 0 \implies q=\{0, \pi, 2\pi\}\\\implies\\q=\{0,\pi,2\pi\}

So, the full solution for q is three values: 0, pi, 2pi. This matches the first choice (which is not complete, but that is ok)

The cost for one ticket to a jazz concert is $7.50. Two tickets cost $15. Write an equation in point-slope form to represent the
Flauer [41]

An equation in the point-slope form to represent the total cost y for x tickets is y-15 = 2(x-2)\\

Let the cost of ticket be C

Let the number of tickets be x

The coordinate for the cost of a ticket will be written as: (x, C)

If the cost for one ticket to a jazz concert is $7.50, this is represented in coordinate form as (1, 7.50)

If two tickets cost $15, his is represented in coordinate form as (2, 15)

Get the slope of the equation

m =\frac{15-7.5}{2-1}\\m=\frac{7.5}{1}\\m = 7.5\\

Get the equation in point-slope form

y-y_1 = m(x-x_1)\\

Substitute the slope and one of the point into the formula:

y-15 = 2(x-2)\\

Hence an equation in the point-slope form to represent the total cost y for x tickets is y-15 = 2(x-2)\\
