A bacteria culture is grown with a population of 15 million cells and kept under observation. The bell population is found to double every hour. How can we use geometric sequences and series to find the total population after six hours? Show all work.
Answers
Answer:
Population after 6 hours is 2.44 *10^12
Step-by-step explanation:
The geometric population growth formula is
[tex]P = P_0 * e^{kt}[/tex]
Substituting the given values in above equation we get
[tex]P = 15 *10^6 * e^{2 * 6}\\P = 15 *10^6 * 162754.791\\P = 2.44 *10^{12}[/tex]
Population after 6 hours is 2.44 *10^12

Step-by-step explanation:
The image is not too clear. Let us assume we need the base AB
AB = opposite
BC = hypotenuse
Sin theta = opp/hyp
Sin 37 = AB/BC
Sin 37 = AB/28
AB = 28sin37
AB = 28(0.6018)
AB = 16.85
AB ≈ 17
Hence the length of AB is 17

Answer:
(-1/2, 3)
Explaination:
Multiply the second equation by 2, then add the equations together.
(4x-y=-5)
2(-2x+3y=10)
Becomes:
4x-y=-5
-4x+6y=20
Then add the equations to eliminate x.
5y=15
then solve 5y-15 for y. (Divide both sides by 5)
5y/5 = 15/5
y= 3
Okay, now we have found y where going to plug it in an equation to solve for x
Going to chosse equation : 4x-y=-5
Subsitue 3 for y in 4x - y = - 5
4x - 3 = -5
( Add 3 to both sides)
4x - 3 + 3 = - 5 + 3
4x = -2
(Divide both sides by 4 )
4x/4 = -2/4
x= -1/2

Translation can be accomplished by reflecting across two parallel lines. The amount of translation is double (twice) the distance between the lines. Any two lines with the same spacing will give the same translation.
Here, the translation is 4 up and 4 right. The amount by which each point is translated is 4√2 units in the direction "northeast", that is, along a line with a slope of 4/4 = 1.
Any line of reflection is a perpendicular bisector of the segment joining the original point and its image. This means we need to identify two lines that have a slope of -1 and that are separated by (4√2)/2 = 2√2 units.
The attachment shows that two lines with this slope that have a separation of 2√2 will have y-intercepts that differ by 4. (The lines shown happen to be the correct answer choices.)
The offered choices of lines have y-intercepts of {5, 6} and {10, 12}. The only pair of lines with y-intercepts that differ by 4 are y=-x+6 and y=-x+10.
_____
Additional comment
We have made sort of a qualitative argument for the correct answer. If you like, you can say that the two lines of reflection each cause the image to be located halfway to its destination. That mean, for example, for point R(2,2), the first image point is R'(4,4). The line of reflection, as we said above, is the perpendicular bisector of this. It will have a slope of -1 and go through the point (3, 3), so its equation is ...
y -3 = -1(x -3) ⇒ y = -x +6
Similarly, the second (final) image point is R''(6,6). We can find the other line of reflection to be one that has a slope of -1 and goes through the point (5, 5). Its equation is ...
y -5 = -1(x -5) ⇒ y = -x +10
These are two of the equations that are offered as answer choices, so should be selected.
As we said at the beginning, any lines with this spacing will do. We cannot presume at the start that each line of reflection will move the image half the distance.

The exponent function of the graph will be W. Then the correct option is D.
What is an exponent?Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as
y = a(b)ˣ + c
Where c is the intercept.
Let the leading coefficient will be 1.
Then the equation will be
y = (b)ˣ + c
The exponent function has a y-intercept at (0, 3).
Then the exponent function is given as,
y = (b)ˣ + 2
Some points regarding exponent function.
The exponent function remains positive for the real value of the x.If the value of x approaches to the negative infinity, then the function tends to zero.If the value of x approaches to the positive infinity, then the function tends to infinity.At x = 0, the function interset the y-axis at (0, 3).The exponent function of the graph will be W.
Then the correct option is D.

The dimensions of a right rectangular prism are shown below.
How many cubes with side lengths of 1 over 6 inch are needed to fill the prism without gaps or overlaps?
Answers
Answer:
91 cubes
Step-by-step explanation:
518 cubes are needed to fill the right rectangular prism without gaps or overlaps.
What is right rectangular prism?"It is a prism whose all faces are rectangles."
What is the volume of rectangular prism?The volume of a rectangular prism with length l, width w and height h is,
V = l × w × h
What is the volume of cube?The volume of a cube having side length 'a' is given by,
[tex]V=a^3[/tex]
For given example,
The dimensions of a right rectangular prism are:
length : [tex]l=2\frac{1}{6}[/tex]
⇒ [tex]l=2.17[/tex] in.
width: [tex]w=1\frac{1}{6}[/tex]
⇒ [tex]w= 1.17[/tex] in.
height : h = 1 in.
So, the volume of a right rectangular prism would be,
⇒ V = l × w × h
⇒ V = 2.17 × 1.17 × 1
⇒ V = 2.5389 cu. in .
Now, the side lengths of a cube : [tex]a=\frac{1}{6}[/tex]
⇒ [tex]a=0.17[/tex]
So, the volume of a cube would be,
⇒ [tex]V=a^3[/tex]
⇒ V = (0.17)^3
⇒ V = 0.0049
Let, 'n' cubes are needed to fill the right rectangular prism without gaps or overlaps.
volume of a right rectangular prism = n × volume of a cube
⇒ 2.5389 = n × 0.0049
⇒ 2.5389/0.0049 = n
⇒ n = 518.14
⇒ n ≈ 518
Therefore, 518 cubes are needed to fill the right rectangular prism without gaps or overlaps
