-π/2 < arctan(x) < π/2
So cos(π/2) < cos(arctan(x)) < cos(0)
0 < cos(arctan(x)) < 1

Answer:
167b + 84
Step-by-step explanation:
Multiplication is indicated between a number and a variable by writing them next to each other. A "product" is the result of multiplication, so "the product of 167 and b" is written 167b.
If you want a value that is 84 more than that, you get it by adding 84.
167b + 84
the answer is d (i think) because anything aboveboard .90, whether it is positive or negative
Its 872 when the integer goes down
