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.

Answer:
x = -2
Step-by-step explanation:
-4x + 3y = 23
y = -7x - 9 // *-3
-4x + 3y = 23
-3y = 21x -27
+++++++++++++++++++
-4x = 21x + 50
-50 = 25x
x = -2
The answer is D because if the perimeter of wxyz can be found by multiplying 2 with the perimeter of hjkl, then the area would be area of hjkl times 2
