For the three-part question that follows, provide your answer to each part in the given workspace. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C. Part A: Explain what the roots of a function are and how to find them. Part B: Calculate the zeros of the function y=-x²-4x+21. Part C: Describe the graph of the function from Part B, including key characteristics of the function.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

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.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
