How many possible values for y are there where y= Cos -1 0

Mathematics
1 answer:
Norma-Jean [14]3 years ago
6 0

Answer:

B) 1 possible value

FOR THIS SPECIFIC INSTANCE

Step-by-step explanation:

If it is Cos -1 (0) and cos is capitalized, that means it is a function and you apply restrictions. Based on the restrictions you get one possible value (I think the value is pi/2)

However, if the problem is cos -1(0) with no capitalization, it is a relation meaning values are infinite because of repetitions. The answers would be pi/2 and 3pi/2 and both would be added/subtracted by 2n(pi).

<h3>Answer: Commutative Property (choice C)</h3>

===================================================

Explanation:

Here are all of the justifications for each step

  • Step 1. None needed. This is the original expression
  • Step 2. Distributive property
  • Step 3. Multiply  (the 3 and 5 multiply to 15)
  • Step 4. Commutative property. Specifically, this is the commutative property of addition which allows us to add any two numbers in any order we want. In this case, the  -15 and 4x terms swap places.
  • Step 5. Associative property. The parenthesis group the first two terms away from the third term.
  • Step 6. Combine like terms. Both 3x and 4x have an x only so they are like terms that combine to 7x. You can think of it as 3+4 = 7, then you just tack an x onto everything to get 3x+4x = 7x.
