Answer:

Nathan’s estimate is reasonable. He spent about $300 and earned about $200 so he should have about $100 less than he started with.

Step-by-step explanation:

Lets use round #s

He buys 10 posters at $30 each, so he spent 10*30 = 300

He sells 5 posters at $40 each, so he made 5*40 = 200

So he made 200 - 300 = -100, meaning he made 100 less than he started with. 100 less from 1000 is $900.

Simplify the trigonometric function
Alisiya [41]

Answer:

  a.  csc²θ

Step-by-step explanation:

You can use the identities ...

  1 +tan² = sec²

  cot = cos/sin

  sec = 1/cos

  csc = 1/sin

___

Then the expression becomes ...

  \cot^2{\theta}(1+\tan^2{\theta})=\cot^2{\theta}\sec^2{\theta}=\dfrac{\cos^2{\theta}}{\sin^2{\theta}\cos^2{\theta}}=\dfrac{1}{\sin^2{\theta}}\\\\=\boxed{\csc^2{\theta}}

Find the exact value by using a half-angle identity.<br><br> tan seven pi divided by eight
murzikaleks [220]

Answer:

  1 -√2

Step-by-step explanation:

  \tan(x/2)=\dfrac{1-\cos(x)}{\sin(x)}\\\\\tan\left(\dfrac{1}{2}\cdot\dfrac{7\pi}{4}\right)=\dfrac{1-\cos\dfrac{7\pi}{4}}{\sin\dfrac{7\pi}{4}}=\dfrac{1-\dfrac{1}{\sqrt{2}}}{-\dfrac{1}{\sqrt{2}}}=\boxed{1-\sqrt{2}}

tan(7π/8) = 1 -√2
