D'(p) = -8p + 160
<span>-8p + 160 = 0 </span>
<span>-8p = -160 </span>
<span>p = 20 </span>
<span>~~~ </span>
<span>B) Number of drills sold when p = 20 is </span>
<span>D(20) = [ -4(20)^2 + 160(20) - 270 ] = 1,130 drills </span>
I think this is right, i tried.
4x+1=1/2(8x+2)
4x+1=4x+1
-1 -1
4x=4x
/4 /4
x=1
The formula for volume of a sphere is 4/3(pi*radius³)
4/3*3.14*12³=7234.56 inches ³
Janine inflated a ball with a radius of 18 cm.
The volume of that ball will be
Volume = 4 / 3 * pi * r^3
Volume = 4 / 3 * 3.14 * 18^3
Volume = 24416.64 cm^3
Janine inflated another ball with a radius of 12 cm.
The volume of that ball will be
Volume = 4 / 3 * pi * r^3
Volume = 4 / 3 * 3.14 * 12^3
<span>Volume = 7234.56 cm^3
</span>
Difference = 24416.64 cm^3 - <span>7234.56 cm^3
</span>Difference = 17,182.08 cm^3
Answer:
1.) In biology, <u>cell theory is the historic scientific theory that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.</u> Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
Part 2-<u>Hans and Zacharias Jansen, Robert Hooke, Matthias Schleiden, Theodor Schwann, Robert Brown;</u> were all the scientists that contributed to the cell theory.
2.) <u>Prokaryotic and Eukaryotic.</u> Prokaryotic cells lack a nucleus and other membrane-bound organelles. Eukaryotic cells have a nucleus and other membrane-bound organelles. This allows these cells to have complex functions.
3.) <u>Homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems.</u> This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range).
4.) I can't help you here, sorry.
8.) <u>Step 1: DNA Replication</u>
<u>Step 2: Chromosome Segregation</u>
<u>Step 3: Separation</u>
Part 2- <u>Mitosis</u>
Part 3- <u>Meiosis</u>
