Answer: y=7
Step-by-step explanation:
V1=60. 60×t1=50×t2=S
V2=50
T=t1+t2=5. 5-t2=t1
60×(5-t2)=50×t2
300-60×t2=50×t2
300=50×t2+60×t2
300=t2×(50+60)
300=t2×110
300/110=t2
S=50×300/110
It hit of a wall. It went ten feet then hit off of a wall then came back.
(2,8) is the answer hope this helped
Answer: 2sqrt(10)
Step-by-step explanation:
I'll do the top left one as an example, you can do the rest.
From the geometric mean theorem, we get that 5/x = x/8.
This rearranges to x^2 = 40
x = 40 = 2sqrt(10)
