Answer:

Option 1,2 and 5 are true.

Step-by-step explanation:

Given : The polynomial  4x^3- 6x^2 + 8x- 12

To find : Which statements are true about the polynomial? Check all that apply.

Solution :

First we find the factor of the given polynomial.

4x^3- 6x^2 + 8x- 12=2(x^2+2)(2x-3)

Now, We check one by one.      

1) The terms 4x^3 \text{ and } 8x have a common factor.

Yes, it is true they have common factor i.e, 4x.

2) The terms  4x^3 \text{ and } -6x^2 have a common factor.

Yes, it is true they have common factor i.e, 2x^2.

3) The polynomial is prime.  

No, It is not prime, and the factored polynomial is 4(2x-3)

4) The factored polynomial is (2x^2-3)(2x + 4).

No, It is not correct. As factored of polynomial is 2(x^2+2)(2x-3)

5) The polynomial can be grouped in different ways to factor by grouping.  

Yes, it is true.

Therefore, Option 1,2 and 5 are true.

Help me! Answer in pic not correct !
sladkih [1.3K]

Answer:

Q'=(4,1)\\R'=(6,-5)\\S'=(3,-4)\\T'=(1,-1)

Step-by-step explanation:

First we have to find the coordinates of the original ordered pairs then we will do the translation.

Q=(1,3)\\R=(3,-3)\\S=(0,-2)\\T=(-2,1)

Now we will add 3 to every x value and add a -2 to every y value.

Q=(1_{+3},3_{+(-2)})\\R=(3_{+3},-3_{+(-2)})\\S=(0_{+3},-2_{+(-2)})\\T=(-2_{+3},1_{+(-2)})

When you do that you will get the new prime points.

Q'=(4,1)\\R'=(6,-5)\\S'=(3,-4)\\T'=(1,-1)

The Demand function for a product is given by:
VikaD [51]

Answer:

The average rate of change of Demand between 40 and 175 units sold is of -0.1045.

Step-by-step explanation:

Average rate of change:

The average rate of a function f(x) in an interval [a,b] is given by:

A = \frac{f(b) - f(a)}{b - a}

In this question:

D(q) = -0.0003q^2 - 0.04q + 23.56

What is the average rate of change of Demand between 40 and 175 units sold?

a = 40, b = 175. So

D(40) = -0.0003*40^2 - 0.04*40 + 23.56 = 21.48

D(175) = -0.0003*175^2 - 0.04*175 + 23.56 = 7.3725

So

A = \frac{f(b) - f(a)}{b - a} = \frac{7.3725 - 21.48}{175 - 40} = -0.1045

The average rate of change of Demand between 40 and 175 units sold is of -0.1045.
