algol13

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.

QUICK HELP!!!!
sasho [114]

Answer:

y =  \frac{3}{4} x -  \frac{3}{2}

Step-by-step explanation:

y =  \frac{3}{4} x - 1→y - y1 = m( x - x1)

y - 6 =  \frac{3}{4} (x - 6)→y - 6 =  \frac{3}{4} x - 6

2(y - 6) = 2( \frac{3}{4} )(x - 6)

2y - 6=  \frac{3}{2}( x - 6)

2y - 6 =  \frac{3}{2} x - 9

- 6 \: from \: both \: sides

2y  =  \frac{3}{2} x - 3

divede \: by \: 2 \: on \: both \: sides

y =  \frac{3}{4} x -  \frac{3}{2}

Hope this helps!

Answer:

V= 42.41

Step-by-step explanation:

V = \pi r^{2}\frac{h}{3}

where r is the radius = 3 and h is the height = 4.5

V= \pi × 3^{2} × \frac{4.5}{3}

V = 42.41
