[Answered] What happens to the brightness of the light from each bulb as each new bulb is added?

[Answered] Solve the inequality: \(4 < n + 2\). First, solve the inequality for \(n\): 1. Subtract 2 from both sides: \[ 4 - 2 < n + 2 - 2 \] \[ 2 < n \] In words, the solution to the inequality \(4 < n + 2\) is that \(n\) must be greater than 2.

[Answered] What is the value of \( f(-4) \) in the piecewise function? \[ f(x) = \begin{cases} -x - 5 & \text{for } -5 \leq x \leq -2 \\ -x^2 + 1 & \text{for } -2 < x \leq 2 \\ (x-3)^2 + 2 & \text{for } 2 < x \leq 4 \end{cases} \] (Note: Make sure the intervals make sense and check if \( x = -4 \) falls within one of the specified intervals.)

[Answered] A basketball rolls off a 0.70 m high desk and strikes the floor 0.25 m away from the base of the desk. How fast was the ball rolling?

[Answered] Name three roles you play in your relationships with others. Explain when you play each role.
