Answer:

  cos(θ) = -12/13

  csc(θ) = -13/5

Step-by-step explanation:

The relation between the cot and csc is ...

  cot² + 1 = csc²

The signs of the cot and sec tell you this is a 3rd quadrant angle, where cos and csc are both negative.

Then ...

  csc(θ) = -√(1 +(12/5)²) = -√(169/25)

  csc(θ) = -13/5

__

  cos(θ) = cot(θ)/csc(θ) = (12/5)/(-13/5)

  cos(θ) = -12/13

Snezhnost [94]

Answer:

The new mean is 77cm

Step-by-step explanation:

If the mean height of the 30 children in a room is 76 cm, then the sum of their ages is

30 \times 76 = 2280cm

If James with height 107cm joins them, then the total number of children now becomes 30+1=31 and the total height becomes: 2280cm+107cm=2387cm

The new mean now becomes:

\bar x =  \frac{2387}{31}  = 77cm

Which equation represents the function represented by the table? 17 POINTS!!!
dybincka [34]

Answer:

  f(x) = -x -1

Step-by-step explanation:

You can make the correct choice by seeing which equation works for the first line of the table.

  f(-1) = -(-1) -1 = 0 . . . . . the first equation works

  f(-1) = -(-1) +1 = 2 . . . not zero

  f(-1) = -1 -1 = -2 . . . not zero

  f(-1) = 1 -(-1) = 2 . . . not zero (same as second equation)
