Question

if a single pane of glass obliterates 3% of the light passing through it, then the percent p of light that passes through n successive panes is given approximately by function p(n)-100(0.97)^x. what percent of light will pass through 25 panes

Answer 1

Answer:

46.7

Step-by-step explanation:

3% of light is obliterated from this pane of glass

1-0.03

= 97% = 0.97

The function has been given as

P(n) = 100(0.97)^x

Let's take our x to be 25 just as the question says

P(n) = 100(0.97)²⁵

P(25) = 46.697

This is approximately equal to 46.7

Therefore the percentage of light that would pass through 25 panes is 46.7
