-π/2 < arctan(x) < π/2
So cos(π/2) < cos(arctan(x)) < cos(0)
0 < cos(arctan(x)) < 1
Answer:
Yes
Step-by-step explanation:
Multiply 4/5 so that they have a common denominator.
14/15 > 12/15 (4/5)
The answer is C 16:20 because both numbers 4&5 are multiplied by four
Well to answer question 43, you would have to multiply the radius but 2 so 8*2= 16 and 16* 3.14= 50.24
ANSWER: 50.24
