The question should be accompanied with choices, below are the choices:

a) sqrt(1-x^2)
b) x/sqrt(1-x^2) 
c) sqrt(1-x^2)/x 
D) 1/sqrt(1-x^2)

The answer should be c) sqrt(1-x^2)/x .

cos u = sqrt (1 - sin^2 u) = sqrt(1 - x^2), and cot u = cos u / sin u.

5q - p + p + 1, please help!

So basically you just add the like terms to simplify the equation. You have 5q-p+p+1 you can cancel out the both p’s because one is negative and one is positive. That leaves you with 5q + 1 they are not like terms so you cannot simplify them so your simplified equation is 5q +1

At the end of three days, $72.9$ % of the original amount of liquid remains in Kyle's container .

Step-by-step explanation:

Here we have , Every day 10% of the liquid present in the morning in Kyle's open container will evaporate. At the end of three days, We need to find what percent of the original amount of liquid remains in Kyle's container . Let's find out:

Let's suppose initially we have 100% of liquid present so ,

At day 1:

10% of the liquid present(100%) in the morning in Kyle's open container will evaporate , So left is :

⇒ $100- \frac{100(10)}{100}$
