Question
I need to know which of the steps listed is wrong. Then how to fix it and solve the rest of the problem please.

Transcribed Image Text:A baseball is thrown in the air from center field to home plate. The path of
the baseball is represented by the equation
p(x)
-7x²+52x + 99. How long will it take for the ball to get
to home plate?
Tell me what steps went wrong as I solved this problem. Explain how to fix
it.

Transcribed Image Text:Problem:
P(x) = -7x2 +52x+99
Step 1: -7x- +52x+99 = 0
Step 2: a = -7 b = 52 c = 99
-52+/(52)-4(-7)(99)
Step 3:
2(-7)
-52+5476
Step 4:
14
52+74
Step 5:
14
11
x = - 9
7
Step 6: x =
11 seconds

- Akira is running around a circular track. Akira runs counterclockwise. From where he starts, it takes him 22 seconds to reach the easternmost point of the track. It takes him 95 seconds to run one complete lap.Bob starts running at the same time as Akira. Bob starts from the northernmost point and runs clockwise. Bob and Akira pass each other for the first time after 26 seconds. How long does Bob take to run one lap of the track? The answer to this question should be the amount of time in seconds rounded to four decimal places that it takes for Bob to run a complete lap around the circular track.arrow_forwardShow the complete solution.arrow_forwardJean typically takes 2 less hours than Donald to assemble a bicycle if each works alone. Jean and Donald worked together to assemble a bicycle for 1 hour, and then Donald finished the job without Jean after an additional 1 hour. How long would it have taken Donald to assemble the bicycle alone? Do not include the units in your answer.arrow_forward
