Question:

If a circle has the diameter of 8, what is the circumference?

Tatum Lynn H.

Answer:

To find the circumference you will use the equation: C = 2(pi)r You will plug in your numbers into the equation. The diameter is 2 times the radius. The diameter is 8, therefore, the radius will be 4. C = 2(pi)(4) C = 25.13

Biology

Question:

Which of the following attributes is common to both prokaryotic cells and eukaryotic cells? - A membrane-enclosed nucleus - The use of DNA as the information storage molecule - Generally about the same size - Membrane-enclosed organelles - The use of proteins as information storage molecules

Tatum Lynn H.

Answer:

When answering this question, you need to compare and contrast prokaryotic and eukaryotic cells. Prokaryotic cells: are generally smaller than eukaryotic cells due to less organelles present, have no well-defined nucleus, have no membrane-enclosed organelles Eukaryotic Cells: have a true nucleus surrounded by a nuclear envelope, use DNA for information, have membrane-enclosed organelles, synthesize proteins using DNA information Using this information, the only answer that is true for both prokaryotic and eukaryotic cells is the use of DNA as the information storage molecule.

Question:

Write an equation for a line passing through (4, 1) and (-2, 0) in slope intercept form.

Tatum Lynn H.

Answer:

You will need to use the point-slope formula y-y1=m(x-x1) This will look like: y-1 = (1/6)(x-4) or y-0= (1/6)(x- -2) You will then need to get the y by itself therefore, it will look like: y=(1/6)(x-4) + 1 or y=(1/6)(x+2) You will then need to distribute the leading coefficient. It will look like: y=(1/6)x-(4/6) + (6/6) or y = (1/6)x + (2/6) After simplifying the equation, your final answer will be: y = (1/6)x + (1/3)
