Answer:
400 ft
Step-by-step explanation:
Let the distance traveled = d
Let the time taken = t
d α t^2
d = kt^2
k = d /t^2
When d = 100 and t = 2.5secs
k = 100/ (2.5)^2
k = 16
d = 16t^2
When t = 5secs
d = 16(5)^2
d = 16 * 25
d = 400 ft
Answer:
3.1
Step-by-step explanation:
19.9 = 9y - 8
+8 +8
27.9= 9y
/9 /9
3.1 = y
Check:
9(3.1) - 8 =
27.9 - 8 = 19.9
13-k
Explanation: it’s just 13 minus the number k
