Perform the indicated operation.<br> h(n)=n-3<br> g(n)=-2n² + 2<br> Find (hºg)(n)

Anni [7]

Step-by-step explanation:

$h(n) = n - 3 \\ g(n) = - 2 {n}^{2} + 2 \\ \\ (h.g)(n) = h(n).g(n) \\ = (n - 3).( - 2 {n}^{2} + 2) \\ = n( - 2 {n}^{2} + 2) - 3( - 2 {n}^{2} + 2) \\ = - 2 {n}^{3} + 2n + 6{n}^{2} - 6 \\ \red{\boxed {\bold{\therefore \: (h.g)(n) = - 2 {n}^{3}+ 6{n}^{2} + 2n - 6}}}$

galina1969 [7]

The answer is c. 10%
We know that the antique dealer would normally charge 20% more than the price he purchased the item for. This also means that the antique dealer is making a profit of 20% on the items he sells. If the antique dealer hosts a 10% off sale, he is reducing the profit he is making from 20% to 10%.
