If sin A + sin^3 A = cos^2 A, prove that cos^6 A - 4cos^4 A + 8cos^2 A = 4.
Sphinxa [80]

Answer:

Step-by-step explanation:

sinA(1+sin^2A) = cos^2A

sinA(2 -cos^2A) = cos^2A

Squaring both sides,

sin^2A(4-4cos^2A +cos^4A) = cos^4A

(1-cos^2A)(4-4cos^2A +cos^4A) = cos^4A

4-4cos^2A +cos^4A-4cos^2A+4cos^4A-cos^6A = cos^4A

4 -cos^6A +4cos^4A -8cos^2A = 0

cos^6A - 4 cos^4A + 8cos^2A = 4

hence proveproven

There are 11 that contain equal numbers of toy cars and 6 that contain equal number of helicopter toy.

<h3>Greatest common factor</h3>

John is filling in party goodie bags with toy cars and helicopters. There are 66 toy cars and 36 helicopters. Each bag must only have either toy car or helicopter - there is no mixing of toys.

Each bag must have the same number of toy cars in it.

Each bag must have the same number of toy helicopter in it.

All bags must have the same number of toys in it.

a) How many bags will contain toy cars?

b) How many bags will contain toy helicopters?

Factors of 66: 1, 2, 3, 6, 11, 22, 33, and 66.

Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, and 36

The greatest common factor of 66 and 36 it s 6

66 ÷ 6 = 11 toy cars

36 ÷ 6 = 6 helicopter toy

Therefore, there are 11 that contain equal numbers of toy cars and 6 that contain equal number of helicopter toy.
