for the polynomial P(x)=4x^2-5x+6 and c =1, find p(c) by (a. direct substitution and (b. the remainder theorem
nata0808 [166]
p(x)=4x^2-5x+6

c=1\implies p(c)=4(1)^2-5(1)+6=5

By the remainder theorem, the remainder upon dividing a polynomial p(x) by a linear binomial x-c is equal to p(c). Via synthetic division, we get

1   |  4   -5   6
.    |        4  -1
- - - - - - - - - - -
.    |  4   -1   5

which translates to

\dfrac{4x^2-5x+6}{x-1}=4x-1+\dfrac5{x-1}

or

4x^2-5x+6=(4x-1)(x-1)+5

Indeed, when x=1, the first term on the right hand side vanished and we're left with 5.

A store marked up the prices p of its merchandise by 11%. The marked-up prices of the merchandise can be written as 1.11p. Which
Y_Kistochka [10]

Answer:

p + 0.11p

Step-by-step explanation:

The merchandise is marked up 11%. This means you pay 100% of the price plus 11%. We can represent that as (1+r) where r is the percent marked above. For 11%, this expression would be 1+0.11. We multiply that by the price p. p(1+0.11). This simplifies to p+0.11p. We can further simplify it to 1.11p.

P(1+r) = p(1+0.11)= p+0.11p=1.11p
