A circle shape is persevered regardless of any rigid transformation <span />
3. First factor as a difference of cubes:
For the remaining group, apply the double angle identity.
5. seems rather tricky. You might want to post another question for that problem alone...
6. Factorize the left side as a sum of cubes:
From here we have to prove that
We can write everything in terms of sine:
(double angle identity)
(angle sum identity)
After some simplifying, we're left with showing that
or
This last equality follows from what you could the triple angle identity for sine,
Anything what i can do for you?
37.025 = thirty-seven and twenty-five thousandths
Answer:
50, and 51.
Step-by-step explanation:
You can basically just use guess and check.
Set up x+y=101.
In this case 50+51=101.
They are also consecutive too.
