Cos(2x) + sin^2(x) = 0
zloy xaker [14]

cos(2<em>θ</em>) + sin²(<em>θ</em>) = 0

Half-angle identity:

cos(2<em>θ</em>) + (1 - cos(2<em>θ</em>))/2 = 0

Simplify:

2 cos(2<em>θ</em>) + 1 - cos(2<em>θ</em>) = 0

cos(2<em>θ</em>) = -1

Solve for <em>θ</em> :

2<em>θ</em> = arccos(-1) + 2<em>nπ</em>

2<em>θ</em> = <em>π</em> + 2<em>nπ</em>

<em>θ</em> = <em>π</em>/2 + <em>nπ</em>

where <em>n</em> is any integer.

T/) The senior classes at High School A and High school B planned separate trips to the county fair.
blsea [12.9K]

Answer:

C) Van: 9, Bus: 25

Step-by-step explanation:

6V + 2B = 104

V + 2B = 59

V = 59 - 2B

6(59 - 2B) + 2B = 104

354 - 12B + 2B = 104

10B = 250

B = 25

V = 59 - 2(25)

V = 59 - 50

V = 9
