Answer:

(a) 20 represents the initial population and

    1.014 represents 1 + % growth of rabbits each day

(b) Average Rate of change = 0.8

Step-by-step explanation:

P.S - The exact question is -

Given - A population of rabbits in a lab, p(x), can be modeled by

            the function p(x)=20(1.014)^x, where x represents the number

            of days since the population was first counted.

To find - (a) Explain what 20 and 1.014 represent in the context of

                   the problem.

              (b) Determine, to the nearest tenth, the average rate of

                   change from day 50 to day 100.

Proof -

(a)

Given that the function p(x) is represented as

[tex]p(x) = 20(1.014)^{x}[/tex]

Here,

20 represents the initial population and

1.014 represents 1 + % growth of rabbits each day

(b)

Given,

[tex]p(x) = 20(1.014)^{x}[/tex]

When x = 50

[tex]p(50) = 20(1.014)^{50}[/tex] = 40.08000 ≈ 40.1

When x = 100

[tex]p(100) = 20(1.014)^{100}[/tex] = 80.32033 ≈ 80.3

Now,

Average Rate of change = [tex]\frac{p(100) - p(50)}{100 - 50}[/tex]

                                         = [tex]\frac{80.3 - 40.1}{50}[/tex]

                                         = [tex]\frac{40.2}{50}[/tex]

                                         = 0.804 ≈ 0.8

⇒Average Rate of change = 0.8

Answer:

XW in the first blank

Z in the second blank

Answer:

A: 3.84% chance.

B: 23.08% chance

The chance of pulling out an A and then a Z and two vowels in two consecutive turns will be 1 / 650 and 2 / 65, respectively.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

The letters of the alphabet are written on pieces of paper and put into a hat. they are then pulled out and not replaced.

Then the total number of letters of the alphabet will be 26.

Then the chance of pulling out an A and then a Z in two consecutive turns will be given as,

P = (1 / 26) x (1 / 25)

P = 1/650

The chance of pulling out two vowels in two consecutive turns will be given as,

P = (5 / 26) x (4 / 25)

P = 20 / 650

P = 2 / 65

The chance of pulling out an A and then a Z and two vowels in two consecutive turns will be 1 / 650 and 2 / 65, respectively.

Answer:

[tex]Volume = 960in^3[/tex]

Step-by-step explanation:

Given

Empty Tank

[tex]Length = 24in; Width=10in; Height = 12in[/tex]

When filled with water, the height is:

[tex]Height = 8in[/tex]

Required

Determine how many more cubic inches needed

First, we calculate the difference between the height of the tank and the height of the water.

[tex]H = 12in - 8in[/tex]

[tex]H = 4in[/tex]

The volume of water to full the tank is then calculated as:

[tex]Volume = Length * Width * H[/tex]

[tex]Volume = 24in * 10in * 4in[/tex]

[tex]Volume = 960in^3[/tex]

Answer:

18 is 14% of 128.5714

Step-by-step explanation:

it's 77.78

Step-by-step explanation:

14: 18*100 =

(14*100): 18 =

1400: 18 = 77.78

Now we have: 14 is what percent of 18 = 77.78

Question: 14 is what percent of 18?

Percentage solution with steps:

Step 1: We make the assumption that 18 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=18$100%=18.

Step 4: In the same vein, $x\%=14$x%=14.

Step 5: This gives us a pair of simple equations:

$100\%=18(1)$100%=18(1).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{18}{14}$100%x%=1814

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{14}{18}$x%100%=1418

$\Rightarrow x=77.78\%$⇒x=77.78%

Therefore, $14$14 is $77.78\%$77.78% of $18$18.

Answer:

Step-by-step explanation:

so this question is about perpendicular lines.    keep in mind that a perpendicular line has a reciprocal slope of opposite sign, from the line it's perpendicular to .  :)  okay so what is that line the robot is on, let's first  

find the slope  , m

m = (y2 - y1)  / ( x2 - x1)  

P1 = (8,6)  in the form ( x1,y1)

P2= (-10,-5) in the form (x2,y2)

then

m = (-5-6) / (-10-8)

m = -11 / -18

m = 11/ 18

and then lets use the point-slope formula with the slope we just found and one of the given points, let's pick  P1

y-6 = 11/18(x-8)

y = 11/18x - 88/18 + 6

y = 11/18x -88/18 + 108/18

y = 11/18x + 20/18

now let's take the reciprocal of the slope and change the sign,  then we have

y = - 18/11x +20/18  ( coordinates robot can move on )

on the graph I'm attaching the green line is the one where the robot first moves, then the purple one.. is the one it turns 90 ° on to .

Answer:

Radius -  4

Apothem -  2

Area - [tex]12\sqrt{3}[/tex] or 20.8

Step-by-step explanation:

Try to draw out my explanation so you know what this looks like.

~~~~

This is an equilateral triangle, so all sides are the same length. The perimeter can be divided by 3 to get each side length...

[tex]12\sqrt{3} \div3 = 4\sqrt{3}[/tex]

Now that we know the side lengths, we can get this started!

~~~~

Now, an equilateral triangle has angles that all equal 60 degrees. We can bisect this into TWO special case triangles of measures 90-60-30.

4 times the square root of 3 will be the hypotenuse, and the smallest leg is always half of that. The larger leg is represented as the small leg times the square root of 3.

[tex]Small=2\sqrt{3} \\Hypotenuse = 4\sqrt{3} \\Long =6[/tex]

By the way, the formula for the area can be either of the two:

[tex]A= \frac{1}{2} bh\\or\\A = \frac{1}{2} NAS[/tex]

we can easily find the area using the first formula.

[tex]A= \frac{1}{2} (4\sqrt{3} )(6)\\A=12\sqrt{3}[/tex]

The radius is the distance from the center to the corners & the apothem is the distance from the center to a side...

So we can divide the big triangle into a mini triangle at the bottom left/right

The height (small leg) of that triangle would be the apothem

The hypotenuse of that triangle would be the radius.

I did the math really quick because this is getting long. Anyhow, the small leg is 2 so is the apothem, and the hypotenus is 4, so is the radius

Answer:

x = 18

Step-by-step explanation:

1/2x - 7 = 1/3 (x- 12)

Multiply both sides by 3

3 * 1/2x - 3 * 7 = 3 * 1/3 (x - 12)

3/2x - 21 = x - 12

Collect like terms

3/2x - x = 21 - 12

1/2x = 9

Multiply both sides by 2

x = 2 * 9

x = 18

Answer:

[tex](x,y) = (-1,0)[/tex]

Step-by-step explanation:

Given

[tex](x+1)^2 = -8(y-2)[/tex]

Required

The coordinates of the focus

First, write the expression in form of: [tex]y=a(x-h)^2+k[/tex]

[tex](x+1)^2 = -8(y-2)[/tex]

[tex](x+1)^2 = -8y + 16[/tex]

[tex]-8y + 16 = (x+1)^2[/tex]

Subtract 16 from both sides

[tex]-8y = (x+1)^2 - 16[/tex]

Divide through by -8

[tex]y = -\frac{1}{8}(x+1)^2 - \frac{16}{-8}[/tex]

[tex]y = -\frac{1}{8}(x+1)^2 +2[/tex]

In this case:

[tex]a = -\frac{1}{8}[/tex]

[tex]-h = 1[/tex]         [tex]h = -1[/tex]

[tex]k = 2[/tex]

The focus of the parabola is:

[tex](x,y) = (h,k + \frac{1}{4a})[/tex]

This gives:

[tex](x,y) = (-1,2 + \frac{1}{4*-\frac{1}{8}})[/tex]

[tex](x,y) = (-1,2 + \frac{1}{-\frac{1}{2}})[/tex]

[tex](x,y) = (-1,2 -2)[/tex]

[tex](x,y) = (-1,0)[/tex]
