The function f(x)= 3(1.4)' gives the length (in inches) of an image after being enlarged by 10% x times.
kondaur [170]

Answer:

3.99 inches

Step-by-step explanation:

<u><em>The correct question is</em></u>

The function f(x) = 3(1.1)^x gives the length (in inches) of an image after being enlarged by 10% x times.

What is the length of the image after it has been enlarged 3 times? Round your answer to the nearest  hundredth

we have

f(x)=3(1.1)^x

This is a exponential growth function

where

f(x) represent the length (in inches) of an image

x is the number of times the image is enlarged

so

For x=3

substitute in the exponential equation

f(x)=3(1.1)^3=3.99\ in

Find the slope of the line that passes
Veseljchak [2.6K]

Answer:

-1/3 or -2/6

Step-by-step explanation:

First, you pick two points, I did (-5,10) and (1,8). Then, because slope is y(2)-y(1)/ x(2)-x(1), the equation would be 8-10/1-(-5) which equals -2/6 which simplifies into -1/3.

(hope this helps!)
