Sec x = 1/cos x
cos 2x = cos^2 x - sin^2 x
sec 2x = 1/(cos^2 x - sin^2 x)
Option A is the correct answer.
Answer:
Area of the other polygon = 4 in.²
Step-by-step explanation:
Area of the bigger polygon : Area of the smaller polygon = square of the side length of the bigger polygon : square of the corresponding side length of the smaller polygon
Let "x" represent the area of the smaller polygon
Thus, we have:
100/x = 20²/4²
100/x = 400/16
100/x = 25
Cross multiply
25x = 100
Divide both sides by 25
25x/25 = 100/25
x = 4
Area of the other polygon = 4 in.²
Answer:

Step-by-step explanation:
Answer:
7200 people
Step-by-step explanation:
Let's say x amount of people tried out.
After round 1: 1/2 x are left.
After round 2: 1/3 (1/2 x) are left
After round 3: 1/4 (1/3(1/2 x))) are left
Each time we multiply by the fraction that are left. By the end we will have
1/6(1/5(1/4(1/3(1/2 x))))
So to find it multiply the denominator out:
![\frac{1}{6}*\frac{1}{5}*\frac{1}{4}*\frac{1}{3}*\frac{1}{2} x\\\\\\\frac{1}{6*5*4*3*2}x\\\\\frac{1}{720}x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%2A%5Cfrac%7B1%7D%7B5%7D%2A%5Cfrac%7B1%7D%7B4%7D%2A%5Cfrac%7B1%7D%7B3%7D%2A%5Cfrac%7B1%7D%7B2%7D%20x%5C%5C%5C%5C%5C%5C%5Cfrac%7B1%7D%7B6%2A5%2A4%2A3%2A2%7Dx%5C%5C%5C%5C%5Cfrac%7B1%7D%7B720%7Dx)
To find x, we set it equal to 10.
![\frac{1}{720}x =10\\x= 10*720\\x=7200](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B720%7Dx%20%20%3D10%5C%5Cx%3D%2010%2A720%5C%5Cx%3D7200)
Answer: I think it’s 22 May 2021
Step-by-step explanation:-
First Step ) August 2020 + 9 Months = May 2021
Second Step ) 4 + 7*2 ( two weeks has 14 days ) or 4 + 7 + 7 = 18
Third Step ) 18 + 4 Days Later = 22
So final answer would be 22 May 2021.
Hope it helps, Good Day! And happy reading
