Rudik [331]

Answer: $4603.82

Step-by-step explanation:

Given

The initial cost of a car is $P=\$20,000$

The rate of depreciation is $i=12.5\%$

Depreciated value after n years is given by

$\Rightarrow P(1-\frac{i}{100})^n\quad \text{where n=no. of years}$

Value after 11 years

$\Rightarrow 20,000(1-\frac{12.5}{100})^{11}\\\\\Rightarrow 20000(0.875)^{11}=\$4603.82$

Answer:

$\frac{height\ of\ a\ person}{height\ of\ flower} =\frac{length\ of\ person\ shadow}{length\ of\ flower\ shadow}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

In this problem

$\frac{height\ of\ a\ person}{length\ of\ person\ shadow} =\frac{height\ of\ flower}{length\ of\ flower\ shadow}$

Rewrite

$\frac{height\ of\ a\ person}{height\ of\ flower} =\frac{length\ of\ person\ shadow}{length\ of\ flower\ shadow}$
