Answer:
both variables are just 0-
Cos
θ
=
√
5
3
or it could be cos
θ
=
√
5
−
3
Explanation:
Since sin
θ
is negative, it can be in the third or fourth quadrant
Drawing your right-angled triangle, place your
θ
in one of three corners. Your longest side will be 3 and the side opposite the
θ
will be -2. Finally, using Pythagoras theorem, your last side should be
√
5
Now, if your triangle was in the third quadrant, you would have
cos
θ
=
√
5
−
3
since cosine is negative in the third quadrant
But if your triangle was in the fourth quadrant, you would have
cos
θ
=
√
5
3
since cosine is positive in the fourth quadrant
Answer:
ƒ(x) = (x - 2)^2 + 1
Step-by-step explanation:
To make f(x) be a translation of the graph of g(x) by (h, k), write it as ...
f(x) = g(x -h) +k
You want to translate g(x) = x^2 by (2, 1), 2 units right and 1 unit up, so the function f(x) is ...
f(x) = g(x -2) +1
