Answer:

C

Step-by-step explanation:

note that sin x = cos(90 - x ) ← Cofunction identity

If x = 36 then 90 - x = 90 - 36 = 54

Hence sin 36° = cos 54° → C

The 5th term in a geometric sequence is 120. The 7th term is 30. What are the possible values of the 6th term of the sequence.
klemol [59]

Answer:

± 60

Step-by-step explanation:

aₙ = a₁ * rⁿ⁻¹

a₇ = 30 = a₁ * r⁷⁻¹ = a₁ * r⁶     (1)

a₅ = 120 = a₁ * r⁵⁻¹ = a₁ * r⁴     (2)

(1)/(2): 30/120 = 1/4 = r²

r = ± 1/2   or ± 0.5

a₁ = a₇/r⁶ = 30/0.5⁶ = 1920

a₆ = 1920 * (± 1/2)⁶⁻¹ = 1920 * ± 1/32 = ± 60

Tim plays a computer game. each game is a win or loss
Drupady [299]

Answer:

If the rest of the question is:

Each game is a win or a loss.

He wins three fifths of his first 40 games.

He then wins his next 12 games.

For all 52 games, work out the ratio wins : losses

Give your answer in its simplest form.​

then the answer is below ↓

Step-by-step explanation:

9:4

of his first 40 games:     3/5 *40=3*8=24  wins

=> of his first 40 games: 24 wins and  40-24=16 losses

next 12 games: 12 wins

so,  for all  52 games: 24+12=36 wins and 16 losses

36 wins and 16 losses

wins: losses=> 36:16=> 9:4
