Answer the s below carefully. provide any relevant sketches. a) pick three points in the first quadrant with six distinct coordinates. b) find the equation for each side of the triangle. label them f. g and h. c) use three definite integrals to find the area of the triangle. d) verify your result from part (c) using a method other than calculus. ee e) verify your result from part (c) using heron's formula. f) suppose the three points are collinear. what is the area of the triangle? what property of integrals is demonstrated by this area formula? consider the following functions. complete the following parts very carefully (r-3)3+6- h(r)= sin(2na) v1+ cos(r r(r=

i dont know sorry

step-by-step explanation:

answer: idk

step-by-step explanation:

step-by-step explanation:

the shape,the size and the distance

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.
