Answer:
Step-by-step explanation:
Start with h(t) = -16t^2 + initial height, which here is h(t) = -16t^2 + 1296. Set this = to zero, which corresponds to the object hitting the ground (h = 0):
0 = -16t^2 + 1296. Dividing all terms by -16, we get t^2 = 81, whose positive square root is 9. It takes 9 seconds for the object to hit the ground.
Divide each number by the previous number. You always get -3.
The pattern is to multiply a number by -3 to get the next number.
The next two numbers are -243, 729
When we have the equation of a line y=mx+b, the "b" value tells you how high or low the line is. your b value when from -7 to 1. with the -7, each point on the line would have been lowered 7 units from its original position. changing the -7 to a 1 will raise the line y=12x+1 8 units, because 1-(-7) = 1+7 = 8.
