Answer:

110

Step-by-step explanation:

Let x = rate #1 and then 155-x=rate #2.

15x + 5(155-x) = 1225

15x - 5x + 775 - 1225

10x = 450

x = 45, second rate is 110

Based on the figure below, the ratio of x/y is equivalent to which trigonometric function?
Ede4ka [16]

Answer: OPTION D.

Step-by-step explanation:

For this exercise it is important to remember the following Trigonometric  Functions:

sin\alpha =\frac{opposite}{hypotenuse}\\\\cos\alpha =\frac{adjacent}{hypotenuse}\\\\tan\alpha =\frac{opposite}{adjacent}\\\\sec\alpha =\frac{hypotenuse}{adjacent}\\\\csc\alpha =\frac{hypotenuse}{opposite}\\\\cot\alpha =\frac{adjacent}{opposite}

Knowing this, we can identify that:

cosA=\frac{AC}{AB}=\frac{x}{AB}\\\\sinB=\frac{AC}{AB}=\frac{x}{AB}\\\\secA=\frac{AB}{AC}=\frac{AB}{x}\\\\tanB=\frac{AC}{BC}=\frac{x}{y}

Therefore, the ratio \frac{x}{y} is equivalent to this Trignometric function:

tanB=\frac{x}{y}

r to the 4 power times t to the third power write a verbal expression for each algebraic expression ??
aalyn [17]

r to the 4th power = r⁴

t to the third power = t³

r to the 4th power times t to the third power would be written as:

(r⁴)(t³)

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.
