Answer:
Step-by-step explanation:
there's no graph selection attached. Can you upload it and then I can help?
Since the sign before the parentheses is a + , we can just remove the parentheses.
<span>5i + (-9 - i) = 5i - 9 - i = -<u>9 + 4i</u></span>
The equation of motion is
s(t) = (1/2)a·t² +v₀·t +s₀
where a is the acceleration, v₀ is the initial velocity, and s₀ is the initial position.
For t in seconds and s(t) in feet, your values make this equation be
s(t) = 5t² -20t +8
It depends on how good the service was. it the service was really bad or just bad than maybe 2$, if the service was ok 5$ and finally if the service was extremely good and everything was just the way you like it then I would say tip 10$-20$
