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

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

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
