Answer:

See below

Step-by-step explanation:

REMEMBER  sec = 1/cos ...so the left side is

[1/cos -1]   /  [1/cos  +1 ]    

  get common denominator for numerator and denominator

[ (1 -cos) /cos  ]  /  [ (1+cos) / cos ]    

 now flip the bottom fraction and multiply to get

[(1-cos/cos) ]  *  [ cos / (1+cos) ]    which simplifies to   ( the 'cos' term cancels)

(1-cos) / (1+cos)              done !

PLEASE HELP ME WITH THIS ALGEBRA QUESTION!! THANK YOU!!

Answer:

The first four terms of the sequence are: {-10,-23,-62,-179}

Step-by-step explanation:

Given recursive formula is:

a_n = 3a_{n-1}+7

First term = a1 = -10

The first term is already known. In order to find the next terms, we will put n=2,3,4 in the recursive formula.

Putting n=2

a_2 = 3a_{2-1}+7\\a_2 = 3a_1+7\\a_2 = 3(-10)+7\\a_2 = -30+7\\a_2 = -23

Putting n=3

a_3 = 3a_{3-1}+7\\a_3 = 3a_2+7\\a_3 = 3(-23)+7\\a_3 = -69+7\\a_3 = -62

Putting n=4

a_4 = 3a_{4-1}+7\\a_4 = 3a_3+7\\a_4 = 3(-62)+7\\a_4 = -186+7\\a_4 = -179

Hence,

The first four terms of the sequence are: {-10,-23,-62,-179}

A square has an area of 100m2. What is the length of each side? please help and explain!!!
Salsk061 [2.6K]
The length is 10 meters.

A square has 4 sides that are all the same length. This means that if one side was, say, 20 cm, every side would be 20 cm.

Recall that to solve for area, you simply have to multiply the length by the width. Since a square has all equal sides, the length and the width will be equal.

Since we know that the area is 100 m^2, we can make an equation:
n * n = 100
n = sqrt(100)
n = 10
