Similar Question 1
<p>Which parent function has the given characteristics?</p> <ul> <li>The domain is not all real numbers, and <code class='latex inline'>f(0)= 0</code></li> <li>The graph has an infinite number of zeros.</li> <li>The graph is even and has no sharp corners.</li> <li>As x gets negatively large, so does y. As x gets positively large, so does y.</li> </ul> <p>Explain.</p>
Similar Question 2
<p>The blades of a particular windmill sweep in a circle 10 m in diameter. Under the current wind conditions, the blades make one rotation every 20s. A ladybug lands on the tip of one of the blades when it is at the bottom of tis rotation, at which point the ladybug is 2 m off the ground. It remains on the blade for exactly two revolutions, and then flies away.</p> <ul> <li>Is the rate of change of the ladybug&#39;s height affected by where the blade is in its rotation when the ladybug lands on it?</li> </ul>
Similar Question 3
<p>Refer to question 1. Suppose each sketch in parts a) and b) begins when the radius from the centre of the wheel to your car is along the negative y-axis. Sketch a graph of your horizontal displacement versus the angle through which you turn for one rotation of the wheel. Which function models the horizontal displacement? Justify your choice.</p>
