If r=[x,y,z] and r0=[x0,y0,z0], describe the set of all points (x,y,z) such that Ir-r0I =1.

sdas [7]

Answer:

The points (x,y,z) that respond to Ir-r0I =1, are all that describes the form $(x-x_0)^2+(y-y_0)^2+(z-z_0)^2=1$ with:

-1+x₀<x<1+x₀

-1+y₀<y<1+y₀

-1+z₀<z<1+z₀

Step-by-step explanation:

All points required in this problem came from applying the definition of modulus of a vector:

Ir-r0I =1.

$|(x,y,z)-(x_{0},y_{0},z_{0})|=|(x-x_{0},y-y_{0},z-z_{0})|=\sqrt{(x-x_{0})^2+(y-y_{0})^2+(z-z_{0})^2}=1\\(x-x_{0})^2+(y-y_{0})^2+(z-z_{0})^2=1^2=1$

The population of Linton is 12 times as great as the population of Elmore the combined population of both towns is 9,646 people

zysi [14]

Let the population of Elmore be "X".
Since that the population of Linton is 12 times as great as the population of Elmore, then it is considered to be "12x".
Since that the sum of both Elmore and Linton is 9.646, then "X + 12x = 9464" x+12x is 13x , so it should be "13x = 9464". Now, it is easy to find the population of Elmore which is 9464 / 13 = 742. Since that the population of Linton is 12 times the population of Elmore, then the population of Linton is "742 * 12 = 8904".

The equation s(n) = 20.bn is an exponential equation, and the hourly percent growth rate of the bacteria would be 85%.

<h3>How to determine the hourly percent growth rate?</h3>

The value of b is given as:

b = 1.85%

Let the hourly percent growth rate of the bacteria be r.

So, we have:

b = 1 + r

Substitute b = 1.85%

1.85 = 1 + r

Subtract 1 from both sides

r = 0.85

Express as percentage

r = 85%

Hence, the hourly percent growth rate of the bacteria would be 85%.
