Girls=3 units
3unit=30
divide both sides by 3
1unit=10

2+3=5
5 total units
1unit=10
times 5 both sides
5units=50

50 total students

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.

$c = -6$

Divide by 2

$c/2 = -3$

Square both sides

$(c/2)^2 = 9$

Hence, the constant to add is:
