So you want height to be 0 so you plug zero into the height and solve from there. You subtract 192 from both sides to get -192=-16tsquared. Then you would divide by -16 and end up with 12 = t^2. Then you find the square root of 12 and get t = 3.464 seconds.
Answer:
A and C are proportional relationships.
Step-by-step explanation:
Recall that a "proportional relationship" has no constant term. Thus, we eliminate Answers B and D immediately.
Answer A represents a proportional relationship: y varies directly with the square of x.
Answer C also represents a proportional relationship: y varies directly with x.
Try multiplying the original price by the decimal so for example 22.50x0.18
That’s the answer just make it into a fraction it is already simplified
Using tan50=p/14=p=14*tan50
total distance betn the end of the class = 28*tan50=53.6910052ft
