Answer:

The answer is cosx cot²x ⇒ the first answer

Step-by-step explanation:

∵ cot²x = cos²x/sin²x

∵ secx = 1/cosx

∴ cot²x secx - cosx = (cos²x/sin²x)(1/cosx) - cosx

  = (cosx/sin²x) - cosx

Take cosx as a common factor

∴ cosx[(1/sin²x) - 1] ⇒ use L.C.M

∴  cosx[1-sin²x/sin²x]

∵ 1 - sin²x = cos²x

∴ cosx(cos²x/sin²x) = cosx cot²x

31.693 Rounded to the nearest Hundredth ​
ioda

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

31.69

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

  • '9' is in the hundredths place. The rounding is the digit to it's right, or '3'.
  • Since 3 is less than or equal to 4, we would round down.

⸻⸻⸻⸻

31.693 ≈ 31.69

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Answer

Find out the how much prize money did she win.

To proof

Let us assume that the total amount prize money did she win be u.

As given

Mrs.Gill won certain prize money in a cooking competition.

She spent half of the prize money on the clothes

= u -\frac{u}{2}\\ = \frac{u}{2}

one third on grocery

= \frac{u}{2} -\frac{u}{3}

(L.C.M of (2,3) =6 )

= \frac{3u -2u}{6} \\=\frac{u}{6}

gave away the remaining Rs.2000 to an orphanage

2000 = \frac{u}{6}

u =Rs 12000

Rs 12000  prize money did she win.

Hence proved
