Answer:
b. -36/77
Step-by-step explanation:
As 0 < x < /2 => tan x > 0
As 0< y < /2 => tan y > 0
We have the formula:
=>
=
=>
As tan x = 1/(cotx) =>
As tan x > 0 => tan x = 8/15
=>
=>
As tan y > 0 => tan y = 4/3
As tan (x-y)=
Answer:
15.9
Step-by-step explanation:
The answer to this question is B, (-infinity, -28].
We can get this answer by first multiplying each side of the inequality by 7. That would get rid of the fraction. When one does that, the result is d + 28
0. That means that d -28. In interval notation, which is the notation the problem is asking us, that would be (-infinity, -28], since d is all values less than -28 this includes infinity, but it also includes -28, so there is a ] around it. That means that the answer to this question is B, (-infinity, -28].
