What is the electrical force between [tex]$q_2$[/tex] and [tex]$q_3$[/tex]? Recall that [tex]$k=8.99 \times 10^9 N \cdot \frac{m^2}{c^2}$[/tex].

you can work only as a farmer 15 hours per week 10x+5y>=150 => 10 x >= 150- 5y :5 => 2x >=30-y => 30-2x <= y x+y<= 25 => y>=30-2x y<=25-x

x = nr. hrs working for a farmer; y = nr. hrs. babysitting; x + y <= 25; 10x + 5y >= 150
a) Solve the system => one of the solution is x =5; y = 20(babysitting) b) 10 + 12 =22 <= 25; 10*10 + 5*12 = 160 >=150.

The system of inequalities that models the situation is 10x + 5y ≥ 150 and x + y ≤ 25, with both variables being non-negative. The combination of working 10 hours on the farm and 12 hours babysitting achieves an income of $160, which meets the goal of at least $150. Therefore, the student's plan is successful in reaching their financial target.
