Angle x is a third quadrant angle such that cos x = -1/5.
Yuki888 [10]

Starting from the formula

\cos^2(x)=\dfrac{1+\cos(2x)}{2}

We can divide all the angles by 2 and we get

\cos^2\left(\dfrac{x}{2}\right)=\dfrac{1+\cos(x)}{2}

And finally

\cos\left(\dfrac{x}{2}\right)=\pm\sqrt{\dfrac{1+\cos(x)}{2}}

Angle x is a third quadrant angle, meaning that it is somewhere between 180 and 270. This implies that x/2 lies between 90 and 135. So, x/2 is a second quadrant angle, and its cosine is negative. This means that we can update the previous equation to

\cos\left(\dfrac{x}{2}\right)=-\sqrt{\dfrac{1+\cos(x)}{2}}

You know that

\cos(x)=-\dfrac{1}{5}

so, plug that value into the expression and you'll get cos(x/2).

Presto Corp. had total variable costs of $180,000, total fixed costs of $110,000, and total revenues of $300,000. Compute the re
Kryger [21]

Answer:

$230,000

Step-by-step explanation:

Contribution margin = Sales - Variable costs

=($250,000 - $137,500)

= $112,500

Contribution margin ratio = Contribution margin ÷ Sales

= ($112,500 ÷ $250,000)

= 0.45

Basically

Break-even sales = Fixed expenses ÷ Contribution margin ratio

=($103,500 ÷ 0.45)

= $230,000
