\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{10}~,~\stackrel{y_2}{-14}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-14}-\stackrel{y1}{10}}}{\underset{run} {\underset{x_2}{10}-\underset{x_1}{(-2)}}}\implies \cfrac{-24}{10+2}\implies \cfrac{-24}{12}\implies -2

\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{10}=\stackrel{m}{-2}[x-\stackrel{x_1}{(-2)}]\implies y-10=-2(x+2) \\\\\\ y-10=-2x-4\implies y=-2x+6

What are the coordinates of the point on the directed line segment from (5,5) to
iogann1982 [59]

Answer:

(x,y) = (6,2)

Step-by-step explanation:

Given

(x_1,y_1) = (5,5)

(x_2,y_2) = (8,-4)

m:n  = 1:2

Required

Determine the coordinate of the partition

This is calculated using:

(x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})

Substitute values for m,n,x's and y's

(x,y) = (\frac{1 * 8 + 2 * 5}{1+2},\frac{1*-4 + 2*5}{1 + 2})

(x,y) = (\frac{18}{3},\frac{6}{3})

(x,y) = (6,2)

An exponential function is graphed for all real numbers. This includes which of the following sets of numbers?
anygoal [31]

<span>In addition to linear, quadratic, rational, and radical functions, there are exponential functions. Exponential functions have the form f(x) = <span>bx</span>, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent.</span>

 

<span>An example of an exponential function is the growth of bacteria. Some bacteria double every hour. If you start with 1 bacterium and it doubles every hour, you will have 2x bacteria after x hours. This can be written as f(x) = 2x.</span>

 

<span>Before you start,   f(0) = 2<span>0 </span>= 1</span>

<span>After 1 hour           f(1) = 21 = 2</span>

<span>In 2 hours              f(2) = 22 = 4</span>

<span>In 3 hours              f(3) = 23 = 8</span>

and so on.

 

 

<span>With the definition f(x) = <span>bx</span> and the restrictions that b > 0 and that b ≠ 1, the domain of an exponential function is the set of all real numbers. The range is the set of all positive real numbers. The following graph shows f(x) = 2x.</span>
