Answer:
it is number 1. because the answer above is equivalent to number 1
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.
Answer:
x
Step-by-step explanation:
If you added x to the equation, then it would become x²+4x+9=0, which is a perfect quadratic square
Equation of circle
(x-h)^2 + (y-k)^2 = r^2
=> (x-10)^2 + (y+4)^2 = 4 is the answer
1 foot = 12 inches
20 feet = 20 x 12 =240 in.
42 x 2= 84 in.
240 - 84 = 156 in. already cut
240 - 156 = 84 in
84/2 = 41 pieces are left to be cut
