Answer:
n = 3
Step-by-step explanation:
-18 = -6n - 6 + 2n
-18 = -6n +2n -6 (Combine like terms)
-18= -4n -6
-18+6= -4n -6+6 (Addition Property of Equality)
-12 = -4n
-12/-4 = -4n/-4 (Division Property of Equality)
3=n
The value of 'n' is 3.
When the penny hits the ground, h will = 0.
So: Set h(t) = 0 = -4.9t^2 + 0t + 150 m
Then 4.9t^2 = 150, and so t^2 = sqrt(150 / 4.9) = plus or minus 5.53 sec.
We can use only the positive root, as we're measuring time.
t = 5.5 sec (answer)
