Part A: 14 + 14 = y or 14•2 = y
Part B: (n•2) - 2 = a
Not 100% sure that this is correct but, hope this helps! :) If you have any questions than ask me.
(First equation:Multiply 6•7=42. 42+5=47)=(second equation:7 to the 2nd power is 49. 49-2=47 )
Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.
Step-by-step explanation:
since the coefficient is the same for the fist three they have the same equation.
the reason: there can only be one line that goes through one point with a specific coefficient.
