Oh, use SOH - CAH - TOA
Sin x = Opposite / Hypotnuse
Cos x = Adjacent / Hypotnuse
Tan x = Opposite / Adjacent
So for #1, for example:
Sin A = 15/17
15/17 would be your answer.
Answer:
D. –X+XY–7y
Step-by-step explanation:
We just have to combine (add) the similar terms... so all terms that have an x in them for example.
–3x + 2xy + 4y – xy + 2x – 11y
Let's first re-write it placing similar terms next to each other
(-3x + 2x) + (2xy - xy) + (4y - 11y)
Then we sum them up, for each similar terms
1x + 1xy -7y
so, x + xy -7y
Answer D.
Answer:
1.f(-3)=-18 f(0)=-12
2.function notation is the way a function is wiritten
3.q=3
Step-by-step explanation:
