A cleaning company charges $140 for each office it cleans. The fixed monthly cost of $450 for the company includes telephone service and the depreciation on cleaning equipment and a van. The variable cost is $50 per office and includes labor, gasoline, and cleaning supplies. (a) Write a linear cost function representing the cost Cx (in $) to clean x offices per month. (b) Write a linear revenue function representing the revenue Rx (in $) for cleaning x offices per month. (c) Determine the number of offices to be cleaned per month for the company to break even. (d) If 25 offices are cleaned, will the company make money or lose money

a) false; the points do not have to be in a straight line.

step-by-step explanation:

the points could be in the shape of a triangle

b is incorrect

c is incorrect because it is saying the immediately don't form one when they are capable of doing so

d is incorrect

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
