2. A exponential decay because it is decreasing by 4. 64÷4= 16 16÷4= 4 4÷4=1
3. Neither because it is arithmetic
Okay, so first, we need to find the discounted rate of the TV:
(1 - 0.2)849 = 0.8(849) = <u>$679.20</u>
Now that we know this, we solve for the price with sales tax:
1.06(679.20) = $719.952 (this can be rounded to 719.95)
The total cost of the TV is $719.95
Pretty sure it’s c

Answer:
A. (x-3)(x+4)(x-6)
Step-by-step explanation:
We need to find the polynomial f(x)=x^3 - 5x^2 - 18x + 72 as a product of lineal factors.
We're going to solve the problem using Ruffini's rule:
1 -5 -18 72
3 3 -6 -72
______________________________
1 -2 -24 0
Then we have:
1 -2 -24
-4 -4 24
______________________________
1 -6 0
Lastly:
1 -6
6 6
______________________________
1 0
Then, the roots are: x=6, x=-4 and x=3
For that reason, the product of linear factors is:
(x-6)(x+4)(x-3) which is option A.
