A. 180
b. 230
c. I'm not sure what that on is
Good question I’m not sure what it is but I’m sure you can look on google
The answer is 4.81x 10^13. By the way your welcome.
I believe its the second one because it say four times the number wich the number is the y and it is = too the number wich is y and increased going up are adding by 9. hope that helped.
Answer:
y = (-16t-2)(t-1)
To find the zeros, let's set y = 0 and separate these two expressions in parenthesis with the zero product property.
0 = -16t-2
0 = t-1
Now let's solve for t and get two zeros.
0 = -16t-2
2 = -16t
<u>t = -1/8</u>
0 = t-1
<u>t = 1</u>
1. Our two zeros are t = -1/8 and t = 1.
2. The two zeros are not both meaningful! Remember that this is modeling time, and we don't really care about -1/8 seconds. We don't need that negative time measurement, so we just want to know what's happening at 1 second. And at one second, the ball is on the ground. Great, so we know that height of ball = 0 after 1 second.
