Step-by-step explanation:
Answer:
y=3x+13
Step-by-step explanation:
Addition: negative four plus negative four plus negative four equals negative twelve
Multiplication: negative four times three equals negative twelve
Division: twelve divided by 3 equals negative four
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)
