Charlidamelio is overrated
A definitely has to be one because it's a fact and you need to know what it looks like. B isn't true because the greatest integer function rounds down values. C is also not correct because a one-to-one graph has one x-value for every y-value. This one doesn't. D has to be true because f[0] = 0 because the Greatest Integer Function requires it to be. And E is also correct because that's in the definition of a Greatest Integer Function. So, your answers are A, D and E.
Cos(angle) = adjacent/hypotenuse
Cos(angle) = 1.5/10
Angle = arccos(1.5/10)
Angle = 81.37 degrees
Although the angle is close, it is over the 80 degrees, so the inspector should be concerned.
The answer is C. No, the adjacent sides are not perpendicular. (Apex)
Answer:
3
Step-by-step explanation:
- 3 - 6 = -3
- Plug -3 in:
- Simplify the fraction. Two negatives equal a positive. It should now look like this:
- Simplify even more. Divide 12 by 3, and change -1 to a positive by removing the plug sign:
- Plug 1 in: 4 - 1
- 4 - 1 = 3
I hope this helps!
