Which one does it simplify to? please
9966 [12]

Answer:

1    +    { \sin}  \theta

Step-by-step explanation:

\frac{  { \cos}^{2}  \theta}{1 -  \sin \theta}  \\  \\  = \frac{  { \cos}^{2}  \theta}{(1 -  \sin \theta)}  \times  \frac{(1  +  \sin \theta)}{(1  +   \sin \theta)}   \\  \\  = \frac{{ \cos}^{2}  \theta(1    +    { \sin}  \theta)}{(1   -   { \sin}^{2}  \theta)}  \\  \\  = \frac{{ \cancel{ \cos}^{2}  \theta}(1    +    { \sin}  \theta)}{ \cancel{{ \cos}^{2}  \theta}}   \\  \\  = 1    +    { \sin}  \theta

What is the slope of a line that is perpendicular to the line whose equation is 3x+2y=6 3 x + 2 y = 6 ?
Tanzania [10]

Answer:

The slope of the line perpendicular to the given line is 2/3

Step-by-step explanation:

step 1

Find the slope of the given line

we have

3x+2y=6

isolate the variable y

2y=-3x+6

y=-(3/2)x+3

The slope of the given line is m=-(3/2)

step 2

Find the slope of the line perpendicular to the given line

Remember that

If two lines are perpendicular, their slopes are opposite reciprocal of each other ( the product of their slopes is equal to -1)

so

m1*m2=-1

we have

m1=-3/2

so

m2=2/3

therefore

The slope of the line perpendicular to the given line is 2/3

If n+1 integers are chosen from the set
baherus [9]

Answer:

Pigeonhole Principle

Step-by-step explanation:

From series {1,2......2n} ; we need to select 'n + 1' integers.

Even integers series from above series = {2,4,6..........2(n-1), 2n}

Odd integers series from above series = {1,3,5........2(n-2), 2n-1}

So, we can choose only n odd integers from the series. Hence, if we choose n+1 integers, atleast one of them have to be even integer.

  • Eg : n = 5, Series = (1,2,3,4,5,6,7,8,9,10}, Odd series = {1,3,5,7,9}, Even series = {2,4,6,8,10}. If we choose 5 +1 ie 6 integers, there must be one even integer, as there are only 5 total odd integers in series.
