The axis of symmetry is X=-2
The vertex is (-2,4)
The maximum is 4
There is no minimum as the maximum is also the vertex of the parabola.
The zeros are (-4,0) and (0,0) or just 0 and -4
The domain is all real numbers from negative infinity to positive infinity
The range contains all real numbers less than or equal to 4 :)
Answer:
n+p=21
Step-by-step explanation:
7n+7p=147si
7(10.5) +7(10.5)=147si
73.5+73.52=147si
On a number line, you could divide the eighths evenly and mark where the 5/8 are and where the 3/8 are. Then you will be able to see which one is farther on the number line.
There are 3 more protons than electrons, so the net charge is +3. You can find this by doing 26+(-23)=3.
It would be B because it makes sense
