Answer:
- Carlton thinks that converting metric units is as easy as moving the <u>decimal point</u>
Step-by-step explanation:
- When you convert the unit, you move decimal point on your answer from the left to the right or from the right to the left the number of places as per relevant prefix.
<u>Example: </u>
- 1 meter = 1000 millimeters (1.0 m = 1000.0 mm)
- 1 milligram = 0.001 grams ( 1.0 mg = 0.001 g)

<h3>Answer: 5 cm</h3>
===================================================
Explanation:
Recall that the range for cosine is from -1 to 1, including both endpoints. The smallest cosine value is what we're after, since we want the height to be as small as possible (to allow the blade be closest to the table).
Effectively, this means we replace the cos(x) with -1 so that it's as small as possible. Then we compute to get:
20*cos(x)+25
20*(-1) + 25
-20 + 25

The height of the fan tip is 5 cm when it is the closest to the table.
Side note: On the flip side, the furthest away the fan tip can get is 20*(1) + 25 = 45 cm. Therefore, the range of y values is
