Answer:
-5
Step-by-step explanation:
the slope is the variable in front of the x
Answer:
6.2832 square units (rounded off to four decimal values)
Step-by-step explanation:
Area of a semicircle =
× π × r²
r (radius) = 2 units
For our semicircle the area =
× π × 2² = 6.28318530718 square units
Or 6.2832 square units (rounded off to four decimal values)
The answer is A,because the way your question is written,there would be 4 molecules of salt (NA) and one molecule of CL (Chlorine)
Y = mix + b would be slope intercept for. your y intercept would be B which is the line that crosses that y intercept your Mx would be a fraction for point slope form like if your slope would be 1 over 2 you would fo up and left twice because of rise over run
Step-by-step explanation:

is a root of the quadratic

This quadratic isn't factorable so use the quadratic formula

The plus and minus sign after b means we going to have two roots.
The roots are

and

We subsitue those values for Beta.
