A pool company has learned that, by pricing a newly released noodle at $4, sales will reach 15,000 noodles per day during the summer. Raising the price to $6 will cause the sales to fall to 13,000 noodles per day.
[Hint: The line must pass through (4,15000) and (6,13000).]
a. Assume that the relationship between sales price and number of noodles sold is linear and write an
equation describing this relationship.
y=
b. Predict the daily sales of noodles if the price is $4.50.
y=noodles

1. minimum

2. 6400

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.
