Answer:

Step-by-step explanation:
Given that the displacement of a particle on a vibrating string is given by the equation
s(t) = 3 + 1 5 sin(3πt),
where s is measured in centimeters and t in seconds.
We are find the velocity of the particle at time t.
We know that velocity is nothing but rate of change of s or derivative of s

Answer: Both of the ballon will meet at 35 above ground
Step-by-step explanation:
1st ballon:15 add 2 min will give you 35 { 15+10+10 }
2nd ballon: 40 add -2 min will give you 35 { 40+(-2.5)+(-2.5) }
Answer:
4(x+3)²+4
Step-by-step explanation:
4x²+24x+40=0
using the equation above
a:4 b:24 c:40
4(x+(24÷2x4))² + (40-(24²÷4x4))
4(x+3)²+(40-36)
4(x+3)²+4
