Answer:
![\displaystyle k = \frac{34}{3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20k%20%3D%20%5Cfrac%7B34%7D%7B3%7D)
Step-by-step explanation:
We are given the polynomial:
![\displaystyle P(x) = 3x^3 - kx^2 + 5x + k](https://tex.z-dn.net/?f=%5Cdisplaystyle%20P%28x%29%20%3D%203x%5E3%20-%20kx%5E2%20%2B%205x%20%2B%20k)
And we want to determine the value of <em>k</em> such that (<em>x</em> - 2) is a factor of the polynomial.
Recall that the Factor Theorem states that a binomial (<em>x</em> - <em>a</em>) is a factor of a polynomial P(x) if and only if P(a) = 0.
Our binomial factor is (<em>x</em> - 2). Thus, <em>a</em> = 2.
Hence, by the Factor Theorem, P(2) must equal zero.
Find P(2):
![\displaystyle \begin{aligned} P(2) &= 3(2)^3 - k(2)^2 + 5(2) + k \\ \\ &= 3(8) - 4k + 10 + k \\ \\ &= 34 - 3k \end{aligned}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cbegin%7Baligned%7D%20P%282%29%20%26%3D%203%282%29%5E3%20-%20k%282%29%5E2%20%2B%205%282%29%20%2B%20k%20%5C%5C%20%5C%5C%20%26%3D%203%288%29%20-%204k%20%2B%2010%20%2B%20k%20%5C%5C%20%5C%5C%20%26%3D%2034%20-%203k%20%20%5Cend%7Baligned%7D)
This must equal zero. Hence:
![\displaystyle \begin{aligned} 34 - 3k &= 0 \\ \\ -3k &= -34 \\ \\ k = \frac{34}{3} \end{aligned}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cbegin%7Baligned%7D%2034%20-%203k%20%26%3D%200%20%5C%5C%20%5C%5C%20-3k%20%26%3D%20-34%20%5C%5C%20%5C%5C%20k%20%3D%20%5Cfrac%7B34%7D%7B3%7D%20%20%5Cend%7Baligned%7D)
In conclusion, <em>k</em> = 34/3.

Answer:
500
Step-by-step explanation:
Define listed price = C
Based on the term, to have the balance on both plan, the equation is 30+90%C = 80+80%C
- 30+0.9C=80+0.8C
- 0.1C=50
- 1C = 500
