What is the area of the rectangle?50 units²54 units²60 units²65 units²A rectangle is graphed on a coordinate plane. The horizontal x-axis ranges from negative 10 to 10 in increments of 1. The vertical y-axis ranges from negative 10 to 10 in increments of 1. The vertices of the rectangle lie on begin ordered pair negative 1 comma 1 end ordered pair and begin ordered pair negative 3 comma negative 5 end ordered pair and begin ordered pair 6 comma negative 8 end ordered pair and begin ordered pair 8 comma negative 2 end ordered pair.

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.

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

thus, the first answer choice, y = sec x, is the correct one
