it is 1 hour and five munites
Step-by-step explanation:
Answer:
1. x = -6, -8, -90
2. solutions for include -5, while -5 is not a solution for
Step-by-step explanation:
Since derivatives lower the degree of polynomials, if you want the second derivative to be zero you have to choose first-degree polynomials.
So, you have
Two polynomials are linearly independent if they are not multiples of each other. So, for example, you might choose and to find two linearly independent solutions.
As for
we want a second-degree polynomial with leading coefficient 1/2 so that we will get 1 when deriving it twice:
If we impose the conditions
we have
So, our solution will be in this form:
To fix , we use the second condition:
So, we have fixed and the solutions is
Answer: 5 new games. 1 old game.
4x5=$20
Add the remaining $2 which Is the cost of 1 old game to get to the total spent.
