Answer: This is a quadratic equation in x and can be solved using the quadratic formula: x = (-b +_ (b^2 - 4 ac)^1/2) / (2 * a)
or (-7 +- (49 - (4 * 2 * 6))^1/2) / (2 * 2) where a=2, b=7, and c=6
and x = (-7 +- (49 - 48)^1/2) / 4 = (-7 +- 1) / 4
giving x = -8/4 and -6/4 or -2 and =3/2
Answer:
The correct answer is 9 seconds.
Step-by-step explanation:
On your graph, use a ruler and your eye to get the best fitting line.
Then find the time in seconds (45) which is between 40 and 50 on the x-axis.
Go across to the y axis. You will find it is about 9 seconds.
