8/13 = 0.6153

y = cos-1(0.6153)

y = 52.0

I'm not totally sure if this is what you mean or if this is.

y = cos(8/13) = 0.9999 which to the nearest tenth is 1.0

Answer:

52.0

Step-by-step explanation:

To solve this, we will perform the inverse cosine:

cos y = 8/13

cos⁻¹(cos y) = cos⁻¹(8/13)

y = 52.0

How do i write y = x -4 in a x and y chart/table?

IrinaK [193]

Okay well it kept saying that I for some reason was not using appropriate words so my long response got deleted.

tldr; we can treat this like a box that we put something into (x) and we get something back from it (y).

We can then take this data we get and put it in a table. This is useful for finding patterns.

I will post a picture of what a table may look like.

Hope this Helps!
