Factor out the cos<span>θ:
</span>cosθ (2sin<span>θ + sqrt3) = 0
</span>Therefore, the only ways this can happen are if either cosθ = 0 or if (2sin<span>θ + sqrt3) = 0
</span>The first case, cosθ = 0 only at θ <span>= pi/2, 3pi/2.
</span>The second case, <span>(2sin<span>θ + sqrt3) = 0 simplifies to:
</span></span>sin<span>θ = (-sqrt3)/2
</span><span><span>θ = 4pi/3, 5pi/3
</span></span><span><span>Therefore the answer is A.

X is at most 30 represent as an algebraic inequality
masya89 [10]

Answer:

x ≤ 30

Step-by-step explanation:

'at most' means the same as 'less than or equal to'.

The sign 'for less than or equal' to is ≤.

So it's simply x ≤ 30.

What is the amplitude of the function?
Licemer1 [7]

Answer:

2

Step-by-step explanation:

Take the absolute value of the lowest y value.

So

| - 1|  = 1

Take the absolute value of highest y value.

|3|  = 3

Add those two together and divide by two.

\frac{1 + 3}{2}  = 2

So the amplitude is 2

Judy bought a coat at a 20% discount sale for $68. What was the original price of the coat?
11111nata11111 [884]
80% of (Cost) = $68

80% is also 0.8:

0.8 x Cost = $68

dividing each side by 0.8

Cost = 68 / 0.8 = 85 = $85

Solve the equation 2cosA = 3tanA
zavuch27 [327]
\bf sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)&#10;\\\\\\&#10;tan(\theta)=\cfrac{sin(\theta)}{cos(\theta)}\\\\&#10;-----------------------------\\\\&#10;&#10;2cos(A)=3tan(A)\implies 2cos(A)=3\cfrac{sin(A)}{cos(A)}&#10;\\\\\\&#10;2cos^2(A)=3sin(A)\implies 2[1-sin^2(A)]=3sin(A)&#10;\\\\\\&#10;2-2sin^2(A)=3sin(A)\implies 2sin^2(A)+3sin(A)-2

\bf \\\\\\&#10;0=[2sin(A)-1][sin(A)+2]\implies &#10;\begin{cases}&#10;0=2sin(A)-1\\&#10;1=2sin(A)\\&#10;\frac{1}{2}=sin(A)\\\\&#10;sin^{-1}\left( \frac{1}{2} \right)=\measuredangle A\\\\&#10;\frac{\pi }{6},\frac{5\pi }{6}\\&#10;----------\\&#10;0=sin(A)+2\\&#10;-2=sin(A)&#10;\end{cases}

now, as far as the second case....well, sine of anything is within the range of -1 or 1, so -1 < sin(A) < 1

now, we have -2 = sin(A), which simply is out of range for a valid sine, so there's no angle with such sine

so, only the first case are the valid angles for A
