X₁ + X₂ / 2 & Y₁ + Y₂ / 2 ------------- This is the formula to plug in the coordinates.
3.5 + 1.5 / 2= 2.5 2.2 + (-4.8) / 2= -1.3
Answer = (2.5,-1.3)
-20 -18 -6 -4 2 4 this is the answer
Answer:
-2
Step-by-step explanation:
Two points (1,0) (0,2) use slope formula 0-2/1-0
No, permutation is for finding out orders like how many ways can you arange the letters x,y,z the answer is 6, because xyz, xzy, yxz, yzx, zyx, zxy
permutations are a branch of probability
probability is (desired outcomes)/(total possible outcomes) or
10/total people registered
Not sure why such an old question is showing up on my feed...
Anyway, let

and

. Then we want to find the exact value of

.
Use the angle difference identity:

and right away we find

. By the Pythagorean theorem, we also find

. (Actually, this could potentially be negative, but let's assume all angles are in the first quadrant for convenience.)
Meanwhile, if

, then (by Pythagorean theorem)

, so

. And from this,

.
So,
