$264.75 I like math it took 15 minutes but I got it
Answer:
Average velocity = (V2 - V1)/2 = (268.8 + 256)/2 = 262.4 m/s
Step-by-step explanation:
The distance fallen s = 16t^2
The velocity v = = 32t
If we substitute the values of t into the velocity v, we'll have
t = 8 s, V1 = 32 x 8 = 256 m/s
t = 8.4 s, V2 = 32 x 8.4 = 268.8 m/s
Identities enable us to simplify complicated expressions. They are the basic tools of trigonometry used in solving trigonometric equations, just as factoring, finding common denominators, and using special formulas are the basic tools of solving algebraic equations.
You use FOIL (first, outer, inner, last) to check your answer. Eg: (x-4)(x+3)then distribute by using FOIL to get 2 2
x +3x -4x -12 then simplify to get x -x -12
