Answer:

B. Cosecant is the reciprocal of sine

Step-by-step explanation:

Well, this is where you have to remember your reciprocal identities in your trigonometric identities!

So:

- Cosecant is the reciprocal of sine

- Secant is the reciprocal of cosine

- Cotangent is the reciprocal of tangent

How I remember them is just the co is with the non-co (cosecant with sine (no co there) and cosine with secant. Tangent with cotangent is pretty easy to remember.)

I'll attach a picture for trig identities! Let me know if you have any further questions :)

masha68 [24]

Answer:

\frac{104}{5} weeks or 20\frac{4}{5} weeks

Step-by-step explanation:

To do this we can set up a proportion

\frac{52}{1} *\frac{2}{5}

This will tell us how many weeks are in 2/5 of a year

Let's evaluate this

\frac{104}{5}

We cannot simplifiy this anymore, so we will leave it as an improper fraction, or a mixed number as shown below

20\frac{4}{5} weeks
