<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 
10 in each do 10 times 3 then subtract total
Answer:
Conditions in the ghettos were appalling. For example, the majority of the apartments in the Warsaw ghetto were unheated during winter, and the Nazis decided that the inhabitants of the Warsaw ghetto could survive on an official food allocation of 300 calories per day (compared with 634 calories for the Poles and 2,310 for the Germans).
The Nazis ordered Jews to wear identifying badges or armbands with a yellow Star of David on them in the ghettos. Many Jews were also required to perform forced labor for the German Reich. The Nazi-appointed Jewish councils (Judenrat) and Jewish police maintained order within the ghettos and were forced by the Germans to facilitate deportations to the extermination camps.
Step-by-step explanation:
We can notice from the figure that : Area of the home plate is equal to sum of the Area of the rectangle ( 8 in x 15 in) and Area of the triangle with height 6 in and base 15 in.
Area of the rectangle : Length x Width
⇒ Area of the rectangle = 15 x 8 = 120 in²
Area of the triangle : 1/2 x Base x Height
⇒ Area of the triangle = 1/2 x 15 x 6 = 45 in²
Area of the home plate = Area of rectangle + Area of triangle
⇒ Area of the home plate = 120 in² + 45 in² = 165 in²
<u>Answer</u> : D
