Answer:
1. 6/15, 0.4, 40%
2. 0.15, 15%
3. 18 green marbles
Step-by-step explanation:
Hello,
s=48t-16t²
a)
s=0==>16t(3-t)=0==>t=0 or t=3
b)
s>32==>48t-16t²>32===>16(t²-3t+2)<0
Δ=9-8=1
==>16(t-1)(t-2)<0
==>1<t<2 (negative between the roots)
Answer:
120
Step-by-step explanation:
They would make 120 because if you multiply 24 by 5 you will get 120.
So you would use SOH CAH TOA and the inverse of whatever we will use to solve this problem. so we have two measurments 40ft and 25ft. so we will use the inverse of SOH which is sin. so Sin^-1(25/40)=38 degrees is your answer.
