Round 2.81 to 2.8 and 3.72 to 3.7. Add both together to get 6.5
Let us find the slopes of the two lines
ax+by=c, slope m1 = -a/b
bx-ay=c, slope m2 = b/a
m1*m2 = (-a/b)(b/a) = -1
Therefore the two lines are perpendicular so the answer is D
Answer:
(0, 1)
Step-by-step explanation:
All other choices do not match the two possible vertices of the square.
We have:
Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:
We clear f(x):
we simply what we can:
Thus, the correct answer is;
