Cells undergoing mitosis double with each cycle. A biologist has a sample containing 15 cells. Which graph and equation represents the number of cells after each cycle occurs?

distance = √(x1 - x2)^2 + (y1 - y2)^2

distance = √(-6 + 1)^2 + (7 - 1)^2

              = √25 + 36

              = √61

To the nearest whole unit:

√61 = 8

Answer:

5 meters

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z -----> the scale factor

P1 -----> the perimeter of the reduced rectangle on the right

P2 ----> the perimeter of the original rectangle on the left

[tex]z=\frac{P1}{P2}[/tex]

substitute

[tex]z=\frac{24}{30}=0.8[/tex]

step 2

Find the width of the reduced rectangle on the right

[tex]P1=2(L+W)[/tex]

substitute the given values

we have

[tex]L=8\ m[/tex] ---> see the attached figure to better understand the problem

[tex]24=2(8+W)[/tex]

[tex]12=8+W[/tex]

[tex]W=4\ m[/tex]

step 3

Find the width of the original rectangle on the left

To find the width of the original rectangle on the left, divide the width of the reduced rectangle on the right by the scale factor

so

[tex]W=4/0.8=5\ m[/tex]

25h-35=440

440+35=25h

475=25h

475÷25=h

h=19

19 hours

It will take 19 hours of lessons.

An equation is formed of two equal expressions. The answer describes the correct solution for the situation It will take 19 hours of lessons. The correct option is D.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that Ahmet rents a piano for $35 per month. He earns $25 per hour giving piano lessons to students. Therefore, the profit earned by Ahmet will be,

Profit = Total Earning - Expenditure

Profit = Total Earning - Cost of renting the piano

Profit = $25x - $35

Where x represents the number of hours

Now, since Ahmet wants to earn a profit of $440, this month. Therefore, we can write,
$440 = $25x - $35

$440 + $35 = $25x

$475 = $25x

x = $475 / $25

x = 19

Thus, Ahmet needs to give 19 hours of lessons in order to earn $440 profit.

Hence, the answer describes the correct solution for the situation is It will take 19 hours of lessons.

[tex]f^{-1}(7)=\dfrac{7-1}{3}=\dfrac{6}{3}=2[/tex]

The inverse of a function is f⁻¹(7) equals 2.

The correct option is B.

To find the value of f⁻¹(7), we need to substitute 7 into the inverse function f⁻¹(x) = x - 1/3.

f⁻¹(7) = (7 - 1)/3

f⁻¹(7) = 6/3

Since 6 divided by 3 is equal to 2, we have:

f⁻¹(7) = 2

Step-by-step explanation:

Let's start with the y-intercept.  (0, 50) is shifted 10 units to the right and becomes (10, 50).  Next, we know the slope is 5.  We can use this to plot more points, or we can use it to write an equation in point-slope form:

y - 50 = 5 (x - 10)

y - 50 = 5x - 50

y = 5x

So the new y-intercept is (0, 0).

What this means is that Jeremy's savings account will be worth $50 in ten years.

If we compare the new y-intercept to the old one, we see that the 10 unit shift to the right is the same as a 50 unit shift down.  Shifting graph B up 50 units will bring us back to the original graph.

33 + 33 + 38 + 35 +37 + 40 + 57 = 273

273 / 7 = 39

33 + 33 + 38 + 35 +37 + 40 = 216

216 / 6 = 36

The mean (average) of the data set without the outlier is 36 and including the outlier is 39. The outlier here being the value 57 which deviates most from the other values in data set.

To find the mean (or average) of a data set, you add all the values together and then divide by the count of the values.

Firstly, for the mean without the outlier, we add 33+33+38+35+37+40 = 216, which we then divide by the 6 values, giving us 36. So, the mean without considering the outlier is 36.

For the mean considering all values including the outlier (57), calculate 33+33+38+35+57+37+40 = 273, then divide by the 7 values, which gives us approximately 39. The answer to the nearest tenth is 39.0. Therefore, the mean of this data set with the outlier is 39.0 and without the outlier is 36.0.

The graph in the attached figure

Step-by-step explanation:

we have

[tex]f(x)=x^{2}-2x+3[/tex]

This is the equation of a vertical parabola open upwards

The vertex is a minimum

The vertex is the point (1,2)

The y-intercept is the point (0,3)

The function does not have x-intercepts

see the attached figure

let's recall that there are 16oz in 1 lbs, so then 12lbs is 12*16 = 192oz, plus 5, that makes it 197oz, so then 12lb 5oz is really 197oz.

likewise, 7lb is 7*16 = 112oz, plus 10 that makes it 122oz.

197 - 122 = 75 oz

and 75 oz is just 16+16+16+16+11, 4lbs and 11 oz.

The Fahrenheit temperature range at which the antifreeze protects the car, converted from Celsius, is -40°F ≤ F ≤ 284°F.

To convert the Celsius range to a Fahrenheit range, you can use the conversion formula, F = (9/5)*C + 32. Using this formula, for -40°C the Fahrenheit equivalent would be F = (9/5)*(-40) + 32 which equals -40°F, and for 140°C the Fahrenheit equivalent would be F = (9/5)*(140) + 32 = 284°F. Therefore, the compound inequality representing the Fahrenheit temperature range at which the antifreeze protects the car is -40°F ≤ F ≤ 284°F.

Please let me know the choices to better help you.

Step-by-step explanation:

I see zeros at x=-2 , x=0 , x=1 , x=3.

Any time it makes like a little U or upside down U at a zero you are going to have a even power on your factor (for which the zero occurs).  If it goes through the zero increasing or decreasing (not making a kind of U shaped upside down or upside right), it is an odd power.

So at x=-2, (x+2) is going to have an odd power

So at x=0,  (x-0) or (x+0) or even just x is going to have a odd power

So at x=1,  (x-1) is going to have an odd power

So at x=3, (x-3) is going to have an even power

So the polynomial could be represented by

[tex]x(x+2)(x-1)(x-3)^2[/tex]

Answer:

c=ab/(2b+a)

Step-by-step explanation:

20^c = 4^c  *  5^c

20^c=  (2^2)^c   * 5^c

20^c= (2 )^(2c)   * ( 5 )^c

Raise both sides to power a

20^(ca)=(2^a)^(2c)  * (5  )^(ac)

20^(ca)=(20^c)^(2c) * (5  )^(ac)

Raise both sides to power b

20^(cab)=(20)^(2c^2b)*(5^b)^(ac)

20^(cab)=20^(2c^2b) * (20^c)^(ac)

20^(cab)=20^(2c^2b) * 20^(ac^2)

Rewriting using law of exponents on right hand side

20^(cab)=20^(2c^2b+ac^2)

Now bases are same so that means the exponents have to be the same, that is we have:

cab=2c^2b+ac^2

assuming c is not 0, divide by c on both sides

ab=2cb+ac

Factor the right hand side

ab=c(2b+a)

Divide both sides by (2b+a)

c=ab/(2b+a)

C  is expressed in terms of b as c = [tex](5^b) / 2.[/tex]

To express c in terms of b in the equation [tex]2^a = 5^b = 20^c[/tex], we need to use the property of exponents that states:

[tex]a^(m * n) = (a^m)^n[/tex]

Let's first express [tex]20^c[/tex] in terms of 2 and 5:

[tex]20^c = (2^2 * 5)^c = 2^(2c) * 5^c[/tex]

Now, we have the equation:

[tex]2^a = 5^b = 2^(2c) * 5^c[/tex]

Since the bases (2) and (5) are equal, the exponents must also be equal:

a = 2c

Now, we can express c in terms of b:

Divide both sides of the equation by 2:

c = a/2

Since we know that a = [tex]5^b[/tex], we can substitute it into the equation:

[tex]c = (5^b) / 2[/tex]

So, c is expressed in terms of b as c = (5^b) / 2.

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-7, -5) and (-5, 4).

Calculate the slope:

[tex]m=\dfrac{4-(-5)}{-5-(-7)}=\dfrac{9}{2}[/tex]

Put it and coordinates of the point (-5, 4) to the equation:

[tex]y-4=\dfrac{9}{2}(x-(-5))[/tex]

[tex]y-4=\dfrac{9}{2}(x+5)[/tex] → the point-slope form

Convert to the standard form Ax + By = C :

[tex]y-4=\dfrac{9}{2}(x+5)[/tex]         multiply both sides by 2

[tex]2y-8=9(x+5)[/tex]        use the distributive property
