Answer:
27.4 metres
Step-by-step explanation:
Um, your question is missing the x's. I'm going to assume, -4.9x^2+22x+5.5
= -4.9(3)^2+22(3)+5.5
= 27.4
At 3 seconds the ball is 27.4 metres above the ground.
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
