Answer:
t=7seconds or 5seconds
Step-by-step explanation:
s=-16t^2 +192t
let s=560ft
560=-16t^2 +192t
16t^2 -192t+560=0
16(t^2-12t+35)=0
(t^2 -12t +35)=0
factoring it ,it will give
(t-7)(t-5)=0
solving for t
t-7=0 or t-5=0
t=7s or t=5s
2X^2 + 4y = 2 * -2^2 + 4 * 3
Your answer is 4.
If this is incorrect, then I am sorry.
Add them together and then you would get the answer
A 7.2-7.3-7.4-7.5-7.6
b 5.60-5.61-5.62-5.63-5.64
