On a hot day, a fan has a mark on the tip of one blade. The equation y
stellarik [79]
<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

5

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 5 \le y \le 45

Aliyah created the circle graph to show the weather for April in her hometown. How many of the 30 days in April were rainy?
Stells [14]

10 Days in April will be Rainy Days

Step-by-step explanation:

Percentage formula will be used to calculate the number of days which will be rainy

Given

Percentage of rainy days = 33%

Total days in April = 30

So 33% of 30 days of April will be rainy

Now

No.\ of\ Rainy\ Days = 33\%\ of\ 30\\=0.33*30\\=9.9

Rounding off to nearest whole number

9.9 => 10

Hence,

10 Days in April will be Rainy Days
