Answer:
9
Step-by-step explanation:
If we find the factors of each and rewrite them like this:
16, 16 x 9, 16 x 9 x 9, etc.
We notice we are multiplying by a factor of 9 every time we increase the number of subscribers.
Answer:
it makes a right angle
Step-by-step explanation:
Answer:
x = -3, y = -4
Step-by-step explanation:
Double the first equation to get 6x - 2y = -10
Now just add the two together and get x = -3. Plug this back in to get y = -4.
Answer:
Step-by-step explanation:
How can you remember the formula?
Well, it helps to know it's the Pythagoras Theorem with something extra so it works for all triangles:
Pythagoras Theorem:
(only for Right-Angled Triangles) a2 + b2 = c2
Law of Cosines:
(for all triangles) a2 + b2 − 2ab cos(C) = c2
So, to remember it:
think "abc": a2 + b2 = c2,
then a 2nd "abc": 2ab cos(C),
and put them together: a2 + b2 − 2ab cos(C) = c2
Answer:
Choice 3: 6 <= m <= 12
Step-by-step explanation:
Domain is where the function is defined. And it is defined between 6 and 12
