Answer:

start with -29, multiply each term by 3

start with 90, multiply each term by 0.2

start with 67 and multiply each term by 2

The colony has 8576 cells after 7 minutes

Step-by-step explanation:

The pattern for the first part of Q2 is multiply each term by 3.

-29, -87, -261, -783... <u>start with -29, multiply each term by 3 </u>

The pattern for the second part of Q2 is multiply each term by 0.2.

90, 18, 3.6, 0.72... <u>start with 90, multiply each term by 0.2 </u>

The pattern for the third part of Q2 is multiply each term by 2

<u>start with 67 and multiply each term by 2 </u>

The colony has 67×2×2×2×2×2×2×2= <u>8576 cells after 7 minutes</u>

Answer:

<em>The graph of </em>y + 1 = −3/5 (x − 4)<em> would be a straight line. The graph figure is attached below.</em>

Step-by-step explanation:

As the linear equation y + 1 = −3/5 (x − 4) is given.

Since y-y₁ = m (x - x₁) is the Point-slope form is the general form y-y₁=m(x-x₁) for linear equations.

Hence, from the linear equation we can determine the slop which is m = -3/5

Also, when we put x = 0 in the linear equation, we determine the y-intercept as follows:

                            y + 1 = −3/5 (x − 4)

                            y + 1 = -3/5(-4)      ∵x = 0

                            y = 12/5 - 1

                            y = 7/5

y-intercept: 7/5

Hence,

Table for some points can be made for x and values as:

<h3><em>x            y</em></h3>

0<em>  </em><em>         7/5</em>

<em>1            4/5</em>

Which is true about the expression 3 square root x 2 square root
dexar [7]

Answer:

Step-by-step explanation:

Neither one of the two given numbers are rational. sqrt(3)*sqrt(2) equals the square root of 6. All three numbers are irrational.

You can try it for yourself.

sqrt(2) = 1.4142

sqrt(3) = 1.732

1.4142 * 1.732 = 2.4493

sqrt(6) = 2.4493

The difference is a rounding error.

So the answer is B. sqrt(6) is totally irrational.

Two similar cylinders have a scale factor of 1.6/3. Find the ratio of their volumes.
Blababa [14]
So assuming that each thing is 1.6:3 smaller
radius=1.6r   to   radius=3r
height=1.6h   to   height=3h

volume=pi times r^2 times height

1.6                                                           3
pi times (1.6r)^2 times 1.6h    to         pi times (3r)^2 times 3h
pi times 2.56r^2 times 1.6h      to       pi times 9r^2 times 3h
 pi times 4.096hr^2              to      pi times 27hr^2

so the ratio is
pi times 4.096hr^2:pi times 27hr^2
divide both sides by pi
4.096hr^2:27hr^2
divide both sides by hr^2
4.096:27

answer is 4.096/27

Someone please help! Due soon! Im really tired and I cant focus, anything helps!..
Helen [10]

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>
