Answer:
D
Step-by-step explanation:
1/4 is equal to 25/100
Aka D
The distance can be found with integ (v(t)= integ(49 _ 9.8t= 49t _ 9.8 /2 t^2
so D(t) = 49t _ 9.8 /2 t^2, for t = 10s, D = 49x10 _ 9.8 /2 x 100 =441
D = 441
-4(2y)+11y=15, -8y+11y=3y=15: y=5
X=2(5)=10
To check your work -4(10)+11(5)=15
15=15
