Express sin(3theta) in terms of sin (theta)

BigorU [14]

3∅ can be rewritten as (2∅+∅)
sin(3∅) = sin(2∅ + ∅)
Opening brackets on the right hand side;
= sin2∅ cos ∅ + cos2∅sin∅
This simplifies to;
= 2sin∅cos^2∅ + sin∅ (1- 2sin^2∅)
= sin∅ (2cos^2∅ + 1 - 2sin^2∅)
= sin∅ (2(1 - sin^2∅) +1-2sin^2∅)
= 3sin∅ - 4sin^3∅

Two kinds of tickets to an outdoor concert were sold: lawn tickets and seat tickets. Less than 400 tickets in total were sold. L

miskamm [114]

Answer:

Tickets to sit on the bench (b) = 150

Tickets to sit on the lawn (l) = 200

Step-by-step explanation:

Tickets to sit on a bench (b)cost $75 each.

Tickets to sit on the lawn (l) cost $40 each

350 tickets had been sold

$19,250 had been raised through tickets sales

This forms a simultaneous equation:

b + l = 350 ... (i)

75b + 40l = 19,250 ... (ii)

Multiplying (i) by 40 and (ii) by 1 we get;

40b + 40l = 14,000 ... (i)

75b + 40l = 19,250 ... (ii)

Subtracting (ii) - (i) we get;

35b = 5250

b = 5250 ÷ 35 = 150

What is the simplified form of 3abc/abc, when abc does not equal zero? Explain using the properties of real numbers.

elixir [45]

3abc / abc
= 3 ( abc ) / abc
= 3

because the real numbers did not have zero. the real number are starting from positive 1 to positive infinity number.
If we suppose a = 1, b = 2, c = 3
abc / abc = 1.

I hope that i helped you :)
