The number of passengers using a railway fell from 190,205 to 174,989 during a 5-year period. Find the annual percentage decreas

lakkis [162]

Answer:

1.65%

Step-by-step explanation:

We will assume the percentage was the same over the 5 years. The number of passengers using a railway is expressed by the formula

$P(t) = P_{o}(1 - r)^{t}$

Where

P(t) is the number of passengers after 5 years

P(t) = 174,989

P₀ is the number of the passengers at the beginning of the period

P₀ = 190,205

r is the rate in percentage r = ?

t is time duration t = 5 years

Substituting these given values into the formula,

$174,989 = 190,205(1 - r)^{5}$

$(1 - r)^{5} = \frac {174,989}{190,205}$

$1 - r = \sqrt[5]{ \frac {174,989}{190,205}}$

$1 - r = \sqrt[5]{0.920}$

$1 - r = 0.9835$

$r = 1 - 0.9835$

$r = 0.0165$

r = 1.65%

The annual percentage decrease over the period of 5 years is 1.65%

Please help me!!!!!!! It's very important!!!!

The formula for the area of a circle is A = (pi)r^2
So if you plugged in the numbers you would get this equation A = (3.14)97^2
Solve the equation and you would get your answer which is 29544.26
Hope this helps! :)
