Answer:
tanx + cotx = 
Step-by-step explanation:
<u><em>Explanation</em></u>
Take R.H.S =
= 
= 
= 
= tanx + cotx
tanx + cotx =
After 20% reduction the price is $48 which means $48 is only 80% of the original price...so let x= original price
<span>48=.8x </span>
<span>60=x </span>
<span>it was $60

<span>Prime numbers are the numbers that are bigger than one and cannot be divided evenly by any other number except 1 and itself. If a number can be divided evenly by any other number not counting itself and 1, it is not prime and is referred to as a composite number. Prime numbers are whole numbers that must be greater than 1. Zero and one are not considered prime numbers. Learn how to determine which numbers are prime.

Answer:
This function would be even.
Step-by-step explanation:
You can tell a function is even if you plug in -x for x and then simplify and it is the same function. This is the case below.
y = 2x^4 + 2x^2 ----> Plug in -x
y = 2(-x)^4 + 2(-x)^2 ----> Simplify
y = 2x^4 + 2x^2
You'll notice the simplified version is exactly the same as the original, which makes it odd.
