Answer:
a) 122.5 m ; b) 10 s
Step-by-step explanation:
Just use the given equation and plug in what you know.
a)
d = 4.9t^2
d = 4.9(5^2)
d = 4.9 * 25
d = 122.5 m
b)
d = 4.9t^2
490 = 4.9t^2
100 = t^2
t = 10 s
Answer:
15 if b is supposed to the side length, √15 if b is the base which is a square.
Step-by-step explanation:
5
1/4n + 3
Plug 8 in for n so 1/4(8) + 3
1/4 x 8 = 2
2 + 3 = 5
