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:
100% = 96
1% = 100%/100 = 96/100 = 0.96
the temperature changed by 96 - 71 = 25.
how many % are these 25 ?
we check how often 1% fits into 25.
that is done by division :
25 / 0.96 = 26.04166667 ≈ 26%
700 / 15 = 46.67 mph and 140 / 3 = 46.67 so your answer is B
Answer: 14) 12 and 15) -27.
Step-by-step explanation:
<em>x - 10 = 2</em>
<em>x= 2+10</em>
<em>x=12</em>
<em />
<em>-16 = x +11</em>
<em>x = -16-11</em>
<em>x= -27</em>
