The blades of a windmill turn on an axis that is 35 feet above the ground. The blades are 10 feet long and complete two rotation

s every minute. Which of the following equations can be used to model h, the height in feet of the end of one blade, as a function of time, t, in seconds? Assume that the blade is pointing to the right, parallel to the ground at t = 0 seconds, and that the windmill turns counterclockwise at a constant rate.

<span>It could be C. If the blade spends twice in a minute, it would be 30 seconds. 30=2pi/B=pi/15. </span>

No equation on your list can be used to model 'h', because
you didn't provide a list.  That leaves me wondering just what
"the following" means, and it leaves me to create an equation
out of thin air.

So there's no way I can help you pick the right choice from
the list of choices.  But if you see anything there that looks
like this:

                             h = 35 + 10 cos( π t / 30 )

then go ahead and pick that one.

Write the numbers in order from greatest to least. 7.982, 7.981, 8.782, 8.981
ziro4ka [17]

Answer:

<h2>8.981, 8.782, 7.982, 7.981.</h2>

Step-by-step explanation:

To order decimals is to subtract, line up, and comparing digits.

Comparing digits is a good way to order decimals for greatest to least.

(Most Understood.)

<h3>Comparing Decimals:</h3><h3 />

We could put numbers in any order to compare digits, but you should look closely:

  • Numbers can<u> Trick You.</u>
  • <u>Be wise, look closely.</u>
  • <u>If the digit is 0 for a number, the other number is greater if it's not 0.</u>
  • Lastly, <u>you (cannot) multiply, divide, add, or subtract.</u>

__________________________________________

First, we pick 2 numbers to compare, maybe 8.782 and 8.981.

We look at the digits for both numbers.

We see 8's, And 7 and 9, 9 is greater, so 8.<u>9</u>81 is the greatest and 8.<u>7</u>82 is the 2nd greatest.

<h3>8.981, 8.782, ?.???, ?.??? Is Our Order so far.</h3>

Our last 2 numbers are 7.981 and 7.982,

We look at the digits for both numbers.

We see 7's, we see 9's, and we see 8's, but 1 and 2. 2 is greater so 7.98<u>2</u> is the 3rd greatest and 7.98<u>1</u> is the least.

<h3>Our order is: 8.981, 8.782, 7.982, 7.981.</h3><h3>We checked it by comparing wisely. (√ Means Check)</h3>

Best of Luck to you.

Answer:

If you know the radius of a circular track, you can use physics to calculate how fast an object needs to move in order to stay in contact with the track without falling when it reaches the top of the loop.
