Answer: $4603.82
Step-by-step explanation:
Given
The initial cost of a car is ![P=\$20,000](https://tex.z-dn.net/?f=P%3D%5C%2420%2C000)
The rate of depreciation is ![i=12.5\%](https://tex.z-dn.net/?f=i%3D12.5%5C%25)
Depreciated value after n years is given by
![\Rightarrow P(1-\frac{i}{100})^n\quad \text{where n=no. of years}](https://tex.z-dn.net/?f=%5CRightarrow%20P%281-%5Cfrac%7Bi%7D%7B100%7D%29%5En%5Cquad%20%5Ctext%7Bwhere%20n%3Dno.%20of%20years%7D)
Value after 11 years
![\Rightarrow 20,000(1-\frac{12.5}{100})^{11}\\\\\Rightarrow 20000(0.875)^{11}=\$4603.82](https://tex.z-dn.net/?f=%5CRightarrow%2020%2C000%281-%5Cfrac%7B12.5%7D%7B100%7D%29%5E%7B11%7D%5C%5C%5C%5C%5CRightarrow%2020000%280.875%29%5E%7B11%7D%3D%5C%244603.82)
Answer:
3.6 m
Step-by-step explanation:
Because the triangle is a right triangle, we can use the pythagorean theorem:
a^2 + b^2 = c^2 (a and b are the legs of the right triangle, and c is the hypotenuse)
6^2 + b^2 = 7^2
36 + b^2 = 49
b^2 = 13
b = 3.6 m
Negative, increase, decrease.
Positive, increase, increase.
