Step-by-step explanation:

Here we have a problem with exponential decays,  we will find that we can expect that 110 rabbits will still be alive at the end of 7 days.

An exponential decay can be written:

P(x) = A*e^(-k*x)

Where:

A is the initial amount.

k defines the rate of decrease.

x is our variable.

In this case, the exponential decay is applied to the population of rabbits, and we know that:

The initial population is 240, then A = 240

P(x) = 240*e^(-k*x)

We also know that after two days (at x = 2) the population was 180, then we can write:

P(2) = 180 = 240*e^(-k*2)

With this equation we can find the value of k:

180 = 240*e^(-k*2)

180/240 = e^(-k*2)

Now remember that:

Ln(e^n) = n

then if we apply the natural logarithm to both sides, we get:

Ln(180/240) = Ln(e^(-k*2)) = -k*2

-Ln(180/240)/2 = k = 0.144

Then the equation is:

P(x) = 240*e^(-0.144*x)

Now with this, we can find the population of rabbits after 7 days, we just need to evaluate the above function at x = 7, we will get:

P(7) = 240*e^(-0.144*7) = 110.3

That we could round down to the next whole number, 110.

Concluding, we can expect that 110 rabbits will still be alive at the end of 7 days.

Answer:

Step-by-step explanation:

1) x² - 8x + 5 = 0

2) No subtract 5 from both sides

x² - 8x + 5 - 5 = 0 - 5

x² - 8x  = -5

3) Now find (8/2) = 4. Add 4² = 16 to both sides

x² - 8x + 16 = -5 + 16

x² - 8x + 16 = 11

4) (x - 4)²  = 11

5) Take square root both sides

x - 4 = ±√11

x = 4 ±√11

Answer:

For a line to be parallel it must have the same slope. So the slope of the new equation is 6.

The slope intercept form is y=mx+b. And we have a point (3,-5). Plug in what we know....

-5=6(3)+b

Solve for b (the y-intercept)

b= -23

Therefore.... y=6x-23

i could be wrong but i did it in my head , but the equation is right . just do that in order

Answer:

( 0.5, - 1 )

Step-by-step explanation:

So here is the equation:

x2 + x1 / 2 For the x coordinate

y2 + y1 / 2 For the y coordinate

x2 is 4 and x 1 is -3 whilst y2 is 2 and y1 is -4.

Thus:

4 + -3 / 2 = 0.5 x coordinate

2 + -4 / 2 = -1 y coordinate

So it becomes (0.5, -1)

// To remove fractions, multiply equations by their respective LCD

Multiply equation [1] by 3

// Equations now take the shape:

[2] y + x = 4

Graphic Representation of the Equations :

-2x + 3y = -3 x + y = 4

Solve by Substitution :

// Solve equation [2] for the variable x

[2] x = -y + 4

// Plug this in for variable x in equation [1]

[1] 3y - 2•(-y +4) = -3

Answer:

y = -26

Step-by-step explanation:

[y = 2 - 2x] + [y = -16 + 2(x - 3)^2​]

y = -16 + 2x - 6^2

y = -16 + 2x - 6^2 + 2 - 2x

y = (+2x - 2x) - 16 - 6^2 + 2

y = -16 - 6^2 + 2

y = -16 - 12 + 2

y = - 28 + 2

y = -26

Step-by-step explanation:

You're letting x = 0.325325325…, which means

1000x = 325.325325325…   (or 325.325, but pretend the underline is actually an overline)

Then the next box you'd fill in with 0.325325325… (or 0.325).

Subtracting these, you have

1000x - x = 325.325325325… - 0.325325325…

999x = 325

Finally, solving for x gives

x = 325/999

Answer:

(-6, 4)

Step-by-step explanation:

We want to define the name of a plane. We will find that some of the possible names are:

IJF, JFE, FEI.

To define any given plane, we can just use two collinear points that are on the plane and a third point, which is on the plane and is not-collinear to the other two points.

Remember that points are collinear if we can connect them with a line.

So for the shown plane, some names can be:

IJF

where IJ are two collinear points and F is the third point that is non-collinear to the other two and also is on the plane.

Other names can be:

JFE

FEI

etc.
