Answer:
x > 1 or x < 7
Step-by-step explanation:
| x - 4 | < 3
± ( x - 4 ) < 3
There are two possible cases
( x - 4 ) < 3 or - ( x - 4 ) < 3
x - 4 < 3 or - x + 4 < 3
x < 3 + 4 or 4 - 3 < x
x < 7 or 1 < x
x > 1 or x < 7
Therefore option 4 is correct.
Answer:
Observational study
Step-by-step explanation:
- See the researcher visits the forest.
- She want to experience or observe the forest fire.
- She want to observe how it affects the animals.
- Hence it's observational study
Answer:
cos y = r/q
Step-by-step explanation:
Sine is opposite divided by hypotenuse. Here, since sin y = 7/q, we can say that the opposite side length is 7 and the hypotenuse side length is q.
Tangent is opposite divided by adjacent. Here, since tan y = 7/r, we can say that the opposite side is 7 (just like above with sine) and the adjacent side is r.
Now, we have a triangle with its two legs labelled 7 and r and its hypotenuse labelled q.
Cosine is adjacent over hypotenuse. Because the adjacent side has a length of r and the hypotenuse has length q, we know that cos y must be r/q.
Hope this helps!
