Answer: 36%

Step-by-step explanation:

Since the price last week, was 4 boxes for $5. Therefore, the price per box will be:

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 ...

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