Which graph represents the function f(x)=0.2x+3?
g100num [7]

Answer:

The top right

Step-by-step explanation:

The y intercept is = 0.2^(0) + 3 = 1+3 = 4

Now let considered some point

Let x = 3

0.2^(3) + 3 = 3.008

Let x = 10000

0.2^(10000) + 3 = 3.00032

As we can see, it approaching 3 so the top right is correct

What is the slope of a line that is perpendicular to the line shown.
sertanlavr [38]

Answer:

3/4

Step-by-step explanation:

First of all, we need to calculate the slope of the line shown. This can be computed as:

m=\frac{\Delta y}{\Delta x}

where

\Delta y = y_2-y_1 is the increment along the y-direction

\Delta x = x_2 - x_1 is the increment along the x-direction

We can choose the following two points to calculate the slope of the line shown:

(-3,2) and (0,-2)

And so, the slope of the line shown is

m=\frac{-2-(2)}{0-(-3)}=-\frac{4}{3}

Two lines are said to be perpendicular if the slope of the first line is the negative reciprocal of the slope of the second line:

m_2 = -\frac{1}{m_1}

Using m_1 = -\frac{4}{3}, we find that a line perpendicular to the line shown should have a slope of

m_2 = -\frac{1}{-4/3}=3/4
