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.

Solve the inequality for x -5x - 49 &gt; 113
Anika [276]
X < -40.5

To find this, here are the steps:

Combine like terms like so:

-4x - 49 > 113

Then, begin to isolate the variable x by adding 49 to both sides leaving you with:

-4x > 162

Then divide by negative four. Don’t forget, dividing by negatives switches the way the sign points so your final product will be:

x < -40.5

Hope this helps!
